same question. looking to buy a replacement LCD to replace a cracked one.
[myTouch 4G General] periwinklewishes:
Every phone that I got from costco has good display but bad chip
[myTouch 4G General] Phateless:
Lol I had the opposite from Costco.
[myTouch 4G General] periwinklewishes:
Really???? How many times did you return yours?
[myTouch 4G General] aalna:
Im not a dev...

I guess thats why after testing two mt4g, one panel 1 and one panel 2, I still dont see a diference. Rofl. Maybe one day!
[myTouch 4G General] Phateless:
Once to Costco and probably 4 or 5 to T-Mobile. Now I have tons of dust under the screen and starting to have touchscreen issues.

I had such high hopes for this phone.... :(
[myTouch 4G General] mackster248:
Ditto.

This has been a huge disappointment. You know what I'm scared of? Is when my warranty ends in NOV and then the phone turns to ****, ie dust, dead eMMC, and my touchscreen is starting to fail.

That's why I'm considering trading it for a SGS4G. Samsung has way better QC IMO.
[myTouch 4G General] kalel33:
They only give that option when they run out of Mytouch 4Gs. You can always buy the extended warranty, if you do another warranty exchange, for $3.99 a month.
[myTouch 4G General] battlekry:
Anyone know a good source, LCD's can be had online from different vendors but anyone know of a good source.
[myTouch 4G General] kalel33:
There was a posting that had an email from HTC that stated the issue was the glass coating, which would make sense. If you look at it from an angle then the problem does seem to be the glass and not necessarily the LCD itself.
[myTouch 4G General] dragone5:
I was thinking of ebay but I don't know if its the digitizer or the lcd screen..

New Digitizer and new LCD might work ?!

I was wondering if I would replace the LCD with an OEM replacement LCD screen and/or a new OEM digitizer, would that fix the washed out screen issue? Has anyone here tried that yet?

I got my first "main" black MyTouch 4G back in December and I got the good, bright, superior screen on the first try :) I bought a used black MyTouch 4G on Craigslist for $ 180 about 2 weeks ago and unfortunately it has the bad washed-out screen, it is made in Taiwan. A few days ago I found a post on Craigslist that someone had a black MyTouch 4G in pieces for $ 45 and jumped on it and I bought it. It is also made in Taiwan but I couldn't pass this deal up :) The LCD and digitizer are broken on it because the lady had dropped it and I have already ordered the OEM replacement parts on eBay. By the way, it is really NOT that difficult to disassemble and reassemble the MyTouch 4G, I'm a gal and I can do it, but then, I'm also a computer tech and I love to diddle with these kind of things and gadgets LOL Just type in "MyTouch 4G disassembly" on youtube and it'll bring up several very good videos on how to take your MyTouch 4G apart.

What I am planning now is to replace the washed out screen on the first MyTouch 4G with the one that is on it's way and put the washed out screen on the MyTouch 4G that is in pieces right now and use that for rooting and flashing.

I will post here if it fixed the problem, I really hope so !! From what I have read, the washed out effect is because of glass coating which I believe has something to do with the digitizer. For those of us who have the washed out screen, it might be a good alternative compared to getting a warranty replacement (that are a pain in the butt to get through T-Mobile and that are most likely refurbished phones and that had problems before according to a T-Mobile representative who I talked to today). Plus, even if they do a warranty exchange, there is no guarantee that the replacement phone doesn't have the same bad screen and you're back on square one.

I will let you know how it goes, the replacement parts should be here by mid-week :)
[myTouch 4G General] Serious_Beans:
How do you know you're getting the "good" digitizer/lcd?
[myTouch 4G General] PCLiteratesJax:
Serious_Beans, that is one thing I have wondered about too, you don't and can't know if the new LCD and digitizer are the "good" ones :) It's a "shot in the dark" I guess. The new LCD came in the mail today, now I only have to wait for the new digitizer. From what I read, the bad screen issue has something to do with glass coating, I am sure that they have most likely fixed the issue with the coating by now, it has been 9 months since the MyTouch 4G has been released :)
[myTouch 4G General] dragone5:
Does the new lcd have a model number or anything like SH or SO?

Sent from my HTC Glacier
[myTouch 4G General] PCLiteratesJax:
No, nothing like SH for Sharp or SO for Sony :( The more I think about it, I don't think it is the LCD itself, I am actually thinking that the reason for the washed out display is the digitizer. When HTC mentioned "glass coating", there is really no glass coating on the LCD but the digitizer certainly has a coating on it, it makes sense because of the display being good when looking straight at it but distorted and washed out when you tilt the phone.
[myTouch 4G General] Belvadier:
I have had a MT4G since November and the first one I had was the bad black model. I called and requested a replacement and received a black model with the good screen.

Unfortunately about 2 weeks ago pixels started burning out in the top left leaving me with a rather large black dot on the screen. I called and requested a replacement and got the bad screen. I kept calling for replacements complaining about the screen and after 3 replacements all with bad screens they said that they couldn't replace my phone with a mt4g again and only a G2 or an HD7.

I picked the G2 and have had it for about 3 days. It's not bad...pretty comparable to MT4G and doesn't lag nearly as much actually and the screen is great. Honestly I could do w/o the keyboard but it doesn't bother me...
[myTouch 4G General] PCLiteratesJax:
Replaced LCD and digitizer and still have a washed out screen :(

Ok, I got the last 2 parts I needed today in the mail and the phone is up and running again and everything works - YAY :) That's the good news. Unfortunately, the screen is washed out despite a new LCD and Digitizer which tends me to believe that it might actually be the video chip on the phone's motherboard that is the culprit on the MyTouch 4G's washed out displays. I'm not sure about that though. Maybe the replacement part(s) are a Sharp LCD or one of those bad coating digitizer panels. I don't know. I just wanted to keep you guys and gals updated :)
[myTouch 4G General] daewond3r:
I did a warranty exchange because of dust under the screen, and I just got my replacement phone today. Sadly it's a Panel type = 1. My last phone (with the dust) was a Panel type = 2.

I'm debating if I want to send it back. Has anyone ever been in this situation? Can I send back the replacement or do I need to send back my dust-riddled phone and then do another exchange?
[myTouch 4G General] Phateless:
Send back whichever one you want. I've done that before, I still have my phone with dust under the screen.
[myTouch 4G General] daewond3r:
I hopped on the t-mobile chat again to ask about another replacement. Took the honest route too (about the screen). Here's the cliff notes.

_Ashley A: I am showing here that this a known issue with the device.

_Ashley A: Customers may report display screen concerns based off manufacturing locations. Concerns include the screen appearing to be washed out when compared to another myTouch 4G with identical settings. T-Mobile myTouch 4G devices are built in two different factories using the same procedures, materials, and high quality standards. It is expected that slight screen contrast variances may occur and are more noticeable at different viewing angles.

Jeremy: Does that mean I'm left to choose between my old phone which has a good display w/ dust under the screen, and my replacement phone which dust-free but has an inferior display?

_Ashley A: Unfortunately, we cannot exchange the phone for this issue.

She then proceeded to explain to me how to adjust the brightness of the screen (brightness, contrast, same thing right? SMH).

I guess I'll spend the day trying to decide if I prefer dust or washed out colors.
[myTouch 4G General] Phateless:
The dust will annoy you less often than the colors and in fewer conditions.
[myTouch 4G General] daewond3r:
That's what I was thinking. Although, I plan on getting the Hercules when it comes out and I thought the dust-less one would have a better resale value.

Decisions, decisions.
[myTouch 4G General] kalel33:
Wow, she actually looked up the issue and she just copied and pasted the policy to her answer. She did her job like she was supposed to. I've read that policy and still don't understand the suggestion of changing the contrast, brightness, etc. in that policy.
[myTouch 4G General] jjbadd385:
Ok, I have a question. I am trying to find out which screen type I have. I followed the instructions, to restart the handset, open up terminal emulator, I type "demsg" (without quotations), & I get a response from terminal emulator that says "permission denied". Can anyone help me figure out why? My phone is unrooted if that helps. Thanks in advance. jj
[myTouch 4G General] daewond3r:
It's dmesg

Maybe that's the problem?
[myTouch 4G General] 420hackr:
Can something bad happen if we have a bad display ?
[myTouch 4G General] raddy:
Hello Everybody

I am planning to buy a used HTC Mytouch 4G soon via ebay.

How can i make sure to not get a faulty piece?

Please help me.
[myTouch 4G General] Phateless:
Read the first post!

Search this thread for dmesg.
[myTouch 4G General] raddy:
Yeah, i just read the updated first post.

But i can't ask an eBay seller to install terminal application and run dmesg and observe a minute detail.

If there is any obvious indicators please suggest.
[myTouch 4G General] Phateless:
Why not, it takes two seconds and you're gonna spend $200 or more. If dude wants to sell the phone he'll cooperate.

Make sure he reboots first.
[myTouch 4G General] raddy:
See, basically establish sellers in ebay won't dare to take so much efforts.

We can't risk our money to unestablished sellers.

So if there is any easy to find evidence, that would be good.
[myTouch 4G General] Phateless:
Do exactly what I just told you.
[myTouch 4G General] erickdj:
The only other indicator would be a good set of screenshots, but that's not very reliable. Why couldn't you ask the guy to install terminal and check out the screen type? Seriously, it takes like two minutes to do all of that. If he's being dodgy about it, then you really don't want to buy his phone anyway.
[myTouch 4G General] erickdj:
It's the other way around... established sellers got there by giving good customer service and will do what they can to stand out from the crowd.
[myTouch 4G General] androph:
Products made in different factories are generally given differnt revision numbering on some parts and on the product (usually some letters after the name)

Based on above I would assume the same was done here.

I have (x1) mytouch with bad screen showing "Glacier XA SHIP ...." in bootloader

I have (x1) mytouch with good screen showing "Glacier PVT SHIP..." in bootloader.

Is it safe to say that XA and PVT indicate the factory of manufacture?

If so, we can assume different parts,methods, etc are used between the factories.

I have seen instances where the quality between factories manufacturer the same product vary enough to create quality issue.

Strangly enough this XA phone now has hboot errors (it was stock with zero mods)
[myTouch 4G General] Phateless:
Location was debunked. There are both good and bad screens from both China and Taiwan.

Check the poll on page 1.
[myTouch 4G General] swan3983:
Urgh!

I'm new here, but recently joined the rooting world and read that XDA was the best place to start. I've been through two G2 phones with T-Mobile (first one sent back after 8 months because the screen blanked out, second G2 sent back because the refurb they sent had a bad/blown out earpiece speaker) and two MT4G phones.

They offered me a new MT4G instead of another G2, so I took that offer. Got the good display and good eMMC, but after two weeks, I was using it and thought there was a dead pixel... it turned out to be dust under the screen. Once I seen it, I couldn't unsee it, and it drove me crazy every time I used the phone since then. I called T-Mobile and they sent a MT4G refurb, and before I even unrooted and switched back to stock on the old one, the refurb not only has the bad display, but has dust under that screen as well!! After doing a ton of reading, apparently the dust under the screen problem happens with several HTC devices. Called T-Mobile again, and they offered another MT4G, Sidekick 4G, or Galaxy S 4G. I took the offer for the Galaxy S 4G, as I haven't read anything online about dust issues or bad displays. *sigh* but there's still no CM7 or MIUI on Galaxy S 4G :( :( All these returns and exchanges have taken place over the last month. Why is getting a device without defects so difficult??

Anyways, as far as displays go, my first MT4G was a winner, my second one a dud.
[myTouch 4G General] Belvadier:
Same exact thing happened to me except where you went from g2 to mt4g I went from mt4g to g2. My first mt4g had the good memory and screen as well and then a pixel died and after repeatedly being shipped a mt4g with the bad screen (it really is horrible) they offered me a g2. I've had it for a few months now and I honestly couldn't be happier. It's a great phone.

They never offered me an sgs4g though as a replacement, they only offered the g2 or of all things and hd7 which i really was not interested in...
[myTouch 4G General] swan3983:
Honestly, I miss my original G2 like crazy. That phone was a beast, and they're definitely awesome. I don't blame you for not wanting the HD7, I wouldn't want one neither. Windows Phone 7... all those tiles... no thanks!!
[myTouch 4G General] myeverything:
Does anyone know if Moblicity will exchange the Panache in Canada ?
[myTouch 4G General] DKMikey:
Rocking the good display, but there is dust under my screen. QQ.
[myTouch 4G General] PCLiteratesJax:
Interesting....

Ok, so I bought another MyTouch 4G made in China with the superior screen on Craigslist for $ 60 but the screen was busted. I ordered a replacement Digitizer and for some reason I broke the LCD while replacing the totally shattered Digitizer. I was so mad at myself but - the replacement LCD I received is SUPERIOR !! I am almost thinking that it's not the LCD or Digitizer but a chip on the motherboard inside the phone that determines if your screen is superior or washed out unless I finally discovered a company for replacement cellphone parts that actually sells the good LCD's. A LCD I bought off eBay was washed out and this one I ordered from mengtor dot com is superior. There's another good thing about this - I really know this phone inside and out now LOL
[myTouch 4G General] kerryking1:
thankyou thankyou
[myTouch 4G General] joemoss:
Good news is I got my first replacement today and it has the good screen but the really bad part is that it came preloaded with the 2.3.4 update which really sucks so now I have a perfect phone that I can't root yet

Fml!!
[myTouch 4G General] PCLiteratesJax:
There is a way to root Gingerbread 2.3.4 :)

Joemoss, I bought a MyTouch 4G that had a broken digitizer which I replaced that had the 2.3.4 Gingerbread update already on it and I thought exactly the same as you. I found this thread here on xda that helped me to downgrade the OS to 2.2.1 via ADB. I was a noob at that but I was able to do it, it took me a little while but I got it to work:) I am now rooted and running Virtuous Unity 2.35.0 with Sense 3.0 which runs GREAT on that phone :) Here is the link: http://xdaforums.com/showthread.php?t=1178912

Good Luck !! :)
[myTouch 4G General] joemoss:
Yeah I've already tried that many times and hours of tries I read the guides and everything I just don't understand adb at all its 4am now so I've given up tonight however tomorrow I am gonna try again and hopefully downgrade but if I still fail I am going to either wait for a video or wait for another method which will hopefully come soon
[myTouch 4G General] nba1341:
Just bought a white mytouch 4g used got the panel 1. Although I am coming from a t mobile comet so this is really a non issue as the comets screen was so small and crappy I am pretty damn happy with it :)
[myTouch 4G General] Zephead:
My wife got the MT4G in Dec '10 and the display is brilliant, I just looked under the battery and it was made in China...are the Chinese ones the better ones or something? It's never had any kind of problem at all.
[myTouch 4G General] smugglur2:
Had a good display since day one, dropped it in the ocean on vacation.. luckily I had insurance. After $130 they sent me a "new" one. seemed to be refurbished and had a bad screen.

I called t-mobile and they sent me another replacement only to have another bad screen and muffled earpiece. Spoke to a manager about getting another one sent out and she said T-mobile and HTC are aware of the 2 different displays and weren't going to give me anymore exchanges. Instead she offered me early upgrades to Slide or Sensation for $267 on top of my $130 I had already paid. (they did offer me a sidekick free of charge, no thanks.)

So I hung up and called again asked a regular rep and she was kind enough to issue another exchange. (I think due to mainly the muffled earpiece) Phone came in the next 2 days and everything was perfect, good screen and everything, seems to be new not refurbished. 3rd time's a charm.

This all took place from august 25th-sept 2nd. Each time they sent me a phone I got them to waive the $5 fee. =)
[myTouch 4G General] Phateless:
Read the thread. Where it was manufactured has nothing to do with it.
[myTouch 4G General] nba1341:
My sister just got a brand new mt4g in black and the panel is type 1 however it does not have any washed out colors at angles and looks identical to the panel 2 pictures.

It looks a lot better than my white mt4g that I just bought on craigslist a few days ago (which is also panel 1).

Is this problem fixed now with panel 1's?
[myTouch 4G General] quikclik2:
Good to know, thanks for helping me figure out that I have the good screen
[myTouch 4G General] gbondoc:
Superior Black Voted.
[myTouch 4G General] qayum:
Same here... I don't think panel 1 is too bad IMO.
[myTouch 4G General] kamui957:
I just had this happen too. I mean, it isn't exactly as rich as some of the pics, but it is not ANYWHERE close to the previous images. My blacks are black, my whites aren't washed out. Ran Terminal Emulator, got a screen type 1. So... yeah, dunno what's going on. Got 28 days left before I'm stuck with it, but it doesn't seem to be a bad display.
[myTouch 4G General] Shirokishi:
well im "screwed" considering my deal is 7 days and on fair use/fair play.

basically if i make a 10 min phone call i now own the phone.

I think its a bit much to keep on demanding until you get a new one but not unreasonable. I wouldn't be surprised if my store had nothing but type 1's.

If there's a way to know before we actually open the phone then i dont think retailers would mind as much
[myTouch 4G General] Phateless:
Read the thread. No way to know except turning it on and dmesg.
[myTouch 4G General] kamui957:
And as a few of us have said, even that isn't working, 'cause we're seeing 1s that don't have washed out screens.
[myTouch 4G General] Phateless:
Hold it side by side with a 2 before you say that.
[myTouch 4G General] invasion2:
Sigh...white model, panel 1..... :(
[myTouch 4G General] kamui957:
I have. It does wash out a little bit, but not nearly as severe as other comparison shots I've seen. I have to be looking at it at much closer to 180 degrees to get any kind of wash out that bad.

PS: I also compared it to my Sprint EVO 4G I still have from less than two months ago. The Evo's screen is very nice and I've never noticed any kind of contrast or washing out with it (with either it or it's predecessor that this one replaced). They wash out at identical levels at identical angles with similar contrast levels. Honestly, I don't have really ANY of the issues I've seen with other 1's shots that people have taken. Nowhere near the washout levels, etc. It's not as dark and doesn't have as high contrast as some of the 2 shots, but I reiterate, it's not anywhere near as bad as the 1 pics I've seen.
[myTouch 4G General] Phateless:
I got my glacier within a couple of weeks of release, and I've had both screens. There is a PROFOUND difference in day to day use.
[myTouch 4G General] MrKickstand:
hmm, this might seem wierd, but, ill try to get pictures up ASAP to prove this...but my MT4G has a Type 2 Panel and amazing screen quality and sharp looking colors and etc, but when i look in the emulator is says it has a Type 1 Panel
[myTouch 4G General] syntropic:
All I know is that there is a really big difference.

I was having wifi issues, and they sent me a replacement. It was the type 2 (or whatever one is not as good), and it was pretty bad. I sent the replacement back instead of my old phone....rather have wifi problems then a lousy screen.
[myTouch 4G General] Snakecharmed:
I know they're different phones and different screens altogether, but I saw an Evo 4G at an oblique angle today and it looked absolutely terrible. Washed out, warm whites, blown-out contrast, everything you've come to expect from the bad MT4G screens. It really looked much like the pictures and YouTube videos of the MT4G with a bad screen.

Interestingly enough, a coworker also has an Evo 4G that I looked at a month ago and I don't recall it looking as bad as the one I saw today. In fact, I was actually surprised that my coworker's Evo 4G looked as good as it did considering the panel's lower color depth. I had to comb through YouTube comments to find anything that resembled confirmation that there were two different screen types in use for the Evo 4G. Perhaps the Evo 4G did get two different displays in addition to their screen grounding issues, but if so, the different displays for that phone didn't cause nearly as much of an uproar as the two that went into the MT4G. I may have to look at my coworker's phone again to make sure I remembered correctly.

Before I rooted my MT4G, I couldn't find my display type in the midst of all that scrolling in Android Terminal Emulator, but the engineering bootloader confirmed that I have the Sony S-LCD screen. Then again, that was never really in question because with the stark differences between the Sony and Sharp panels captured on still camera, I got to be pretty good at picking out the screens in eBay auction pictures.
[myTouch 4G General] Phateless:
I remember noticing this too. My coworker's evo 4g most definitely has the good screen. The sensation also has two screens. So did the mytouch 3g. Apparently this is a common thing for HTC phones.

[myTouch 4G General] Jottle:
So sad. I had a great panel 1 screen mt4g for the last year or so, but the sense ui and app always ran slowly. Unfortunately, it was impossible to fix this despite using other roms and factory resets. The sad part is I initiated a warranty exchange knowing full well that I'd end up with a refurg. made in Taiwan, panel 2 phone. Sure enough, received my replacement yesterday. It runs nice and speedy, but that lower quality screen is total crap compared to the better one. It's only something you'd know about if you ever saw the good screen. I can live with the crappier screen versus having a slower phone. Some may not feel the same, but if you're doing a warranty exchange, I'm sure you're more likely to receive the crappier sreen.
