did this, but also put some foam on the little connector to the left of the dpad connector too. The one that joins the lcd to the main ribbon cable back to the phone. I also put a piece on the connecter that connects the screen back to main phone. Working 100% now, hopefully the WSOD, button failure and screen alignment issues dont return :)

Just waiting on that Touch Pro to hit Australia now :) :)

Another success story

Hi people,

there seem to be many different reasons causing a white screen on hermes.

My device was also affected :(. While pressing on D-pad with my thumb very firmly, everything was fine.

So i decided to diassemble the device and check all connections to the TFT-unit, like mentioned in this thread.

After checking every connector very intensely, i had to realize that everything was in right in place.

Flat cable O.K., nothing broken on the connectors but still white screen.

With the unit mostly dissasembled i reconnected the TFT-unit and exerted little pressure on the main PCB.

...you might guess what happened!

While pressing screen O.K., no pressure ...white screen again.

I took a pencil and tried to isolate the area that caused the error.

In the end there very two chips, that seemed to be the cause of all evil:

The Samsung CPU and the ATI GPU.

While touching these components the white screen went away!

I decided to try the hot air gun method, that was also described here by cool2bdave.

O.K. there was nothing to loose, i thought ;)

The Samsung chip is a stacked component and could easily be damaged,

so i decided to heat the ATI GPU first (it is mechanical less complex and smaller!)

Using some solder fluid, i heated the component about three minutes, put some fluid and heated again about three minutes.

The mainboard is absorbing a lot of heat, so don't be shy:p

Afterwards i reconnected the TFT-unit...

Voila, what a nice screen!

Everything working again no white screen anymore :D

Thanks for all the excellent advices in this thread!!!!!

Cheers,

scholbert

tons of thanks

after days of fighting with white screen issue on my 8525, finally it can be fixed now...a long long journey to joy ^_^

Thanks to this great forum.

Honestly, in the first day I got to give-up with the problem..

But after read all posting in this forum,googling nowhere/anywhere ? ^_^

Yeah, yes I did it...after read deeply this manual from this post

http://xdaforums.com/showthread.php?t=340426

My story...

Borrow the tools from my friend, dismantling all parts, clean the connector using propanol, reseating the flex cable (don't forget to double check for any physcal damage).

Re-assembling the parts, power-on the device,..eeekkk..oh no still white screen.

Put 8525 in the freezer, to cooling down the parts ?? (ops, what's I'm doing ? .pls don;t try it at your home...^_^ ..I've sealed my device using special packaging ...

Ten minutes on freezer is enough...pull it out then I got to sleep....

next day, using ActiveSync ..tried to install MyMobile (yes, it's Display Mirror) to access 8525 remotely. Seems everything looks good but on 8525 still white screen..yeah.I'm happy enough this time...nothing todo..

What I'm thingking ..howto hard reset or flashing the unit using the latest ROM (bad or good ideas?)..nothing to loose to try...d

Yeah, I did it again...hard reset completed but white screen is persistent..eeeeks The problem getting worst..how to check and perform screen alignment after hard reset while white screen still remain?

I do some search on forum..found a solution

Create welcome.not file, copy it into my microSD..insert it into 8525..and do

hard reset once again.

WHat's a suprise..white screen is missing now!

Oh yes.I just by passing the screen alignment...and successfuly perform hard eset..my 8525 alive...in firts time use, i can do screen alignment using stylus on 8525's screen

Yeah I'm happy enough now..but to ensure everything is running fine..I've to wait for one or two days...hopefully no more white screen..or I'lll back to fight with it ^_^

Thanks

done foam thing but still no good, must be d-pad connector cos only happens when i move down, does that mean i need some flex cable? anyone know were from in uk to order one?

cheers :confused:

edit: added more foam, screen ok but d-pad not working, screw came off connector with being to tight!

bought another spv m3100 off ebay, prob cheaper in the long run......spare charger battery screen etc.
[8525, TyTN, MDA Vario II, JasJam General] n_tops:
Symptoms?

I've been reading the forums for a while, and in the last couple of weeks my M3100 has started to go rapidly down hill. While my screen is defiantly fading to white, it doesn't match all the symptoms presented by others.

At random intervals (camera, video and music generate it almost without fail) I will get flickers across the screen(horizontal lines) and the phone will freeze, this gets progressively worse, with the screen eventually going completely white. By pulling slightly on the upper edge of the phone it often springs back to life. Eventually the phone completely locks up.

I have tried a few ROMs including the original orange WM5 and the results are fairly consistent (subjectively it seemed to occur less often with WM5)

From the forums, it appears that their phone continues to work and only the screen goes, had anyone else had these symptoms and established a cause?

I have made a youtube video to demonstrate the problem.

Any assistance would be helpful, I'm off to buy a torx 6 screwdriver to take it apart tomorrow. It could well be up on E-Bay for parts in the near future!

Thanks in advance

white screen fixed Again

Follow up to my previous post. Retouching the solder points proved to solve things for a little over a month, then it got worse than ever.

So based on cool2bdave's post about the xylinx chip I set out to reflow the solder on the dpad board.

I followed cool2bdave's directions except that instead of using a heat gun

I used a toaster oven and a temperature probe to reflow the entire board.

This may sound silly but there are many tutorials on this method on the net.

The heat profile I followed was from here.

http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s2006/ki38/Webpage/index.html

I am happy to report that after three weeks the phone has been problem free. Thanks to all in this thread.
[8525, TyTN, MDA Vario II, JasJam General] n_tops:
Solved, New battery and everything appears fine so far.

Think I have managed to solve this, replaced the battery and now it seems to run just fine. Hopefully this might be of use to someone else.

White screen caused by faulty IC on PCB A (located under the directional keypad)

I am inclined to agree with you. I had the same problem and took my V1605 (hermes 200) to service center who fixed it for me within 2 hours.

:):):) The technician confirmed that the problem is with an IC on PCB located under the directional keypad. It cost me GBP25. I hope this helps.

I had my hermes for 18 months before it gave me white screen and d-pad issues, after a pretty insignificant drop off my bed.

After putting up with it for a few weeks, I decided to go ahead with the fix described in the first thread. I've never pulled a phone apart before.

The steps are pretty straight forward as long as you take your time and have the right tools (3 small screwdrivers).

For foam I cut up bits of an old dust mask and shoved it in the gap on the back of the chassis to cover the long bottom electronics, then carefully placed another bit on top of the conector and closed it up again.

I can tell straight away that the problem is gone but long term use we will see what happens.

I really can't make it work.

I thighted the screw near the flat..but it was worst. Completely white screen. Then i tried to disconnect and reconnect it carefully, but it makes false contacts.

I tried with few foam...i tried with more foam...

I'm just giving up. :(

Its working man thank you very much but instead i put 3 to 4 layers behind the screen and its really working,

Heya,

I've been having this white screen problem for a very long time. About a year ago, the screen started to go white randomly and squeezing the phone would make it come back. It eventually got worse and i couldn't do anything the get the phone back.

Then one day I was stuck at work and the work cordless phone battery died and my phone was getting the white screen again. I needed to make an emergency phone call and was unable to. I got so angry that i smashed my fist on it, cracked the lcd and broke the touch screen. I ended up putting it in the corner at home and its been collecting dust all this time.

After switching to an old sony for a while, I ended up buying an LG KU990 viewty phone which i totally regret. It looks nice but isn't very practical. I guess, being a female, i should learn not to go for looks first :P

So Anyways, i wanted to go back to using my pda phone for work. I bought a new LCD and touchscreen from ebay and decided to reassemble the phone. I followed the instructions and replaced it with no problem. The only issue is that i have a permenant white screen. I tried putting the little foam strips in but it didn't work. Then i setup the test method described in previous posts and was putting pressure on the certain connecters and ribbon cables but screen is still white.

I'm not really sure what to do anymore and I just spent $80 for the new lcd. I don't really want to take it to any random repairer because i'm female, they tend to think i don't know anything and it makes me feel really degraded.

Does anyone have any suggestions? or know any decent repairers in Sydney, Australia that have experience with this problem?
[8525, TyTN, MDA Vario II, JasJam General] eld0ra:
Hooray! My partner was doing some research and found some new information which sort of helped.

Apparently there are two types of LCD for the hermes phones and depending on the factory LCD, You can only replace it with the same LCD otherwise you get a white screen. The only difference between the two physically is the colour of the ribbon cable that’s on the back of the screen. It can be either black or gold.

So, finding out this information, I disassemble the phone again for like the 6th time to find out that I did actually buy the right LCD for the phone. I was still puzzled and just ended up assembling the phone again carefully. But this time, for some reason the screen started working. I didn’t do anything different. I must have just connected the ribbon cable to that flip connection properly. That connection is a little bit fiddly and fragile. But yeah, good news for sure. It works!

It’s only been 1 day and I’ve had no white screen issues. But we’ll see.

Thanks for the information! :D

Well After a pounding heart whether i am going to Fix my Hermes or Brick it. I manage to follow the walk through to fix the white screen of death. And so far so good. D-pad is working fine and i dont find any white screens after that. Although i was unable to get hold on the foam so i used a thick double sided tape which can found behind the hooks that care attached on the walls to hangs something like cloths etc. I used it on the location as mentioned on the page 3 with pictures.

I used this tape for tow reason as first it has sticky end to we dont need any kind of tape to attach it and its thickness gives an extra pressure.

I will update if i find these errors coming back again after this solution.

Who ever invented this technique and Improved it great thanks to you.

:):):)

But after putting back my TYTN i found a rectangular shaped rubber with a engraved end as it gets hold on to somthing but i cant find it where it goes. I dont have a good camera to give a snap shot if any one know for what i am talking about . Please let me know where it goes.
[8525, TyTN, MDA Vario II, JasJam General] MikeChannon:
Well done, lets hope it lasts.

The black rubber piece is most likely the microphone protector / muffle. You can just make it out (amongst the shadows) on the right side of this picture half way down. It's a pest to keep in place when you re-assemble:

Mike
[8525, TyTN, MDA Vario II, JasJam General] freeinspace:
Thank you Mike for your help. I will save the picture for further reference.

So far my PDA is doing great all the kays are working normal. and NO white screen at any stage not even at soft reset. Hope Its gone for good.

As it is working fine, i dont want to open it. so is this rubber thingy important or i can leave it out till i need to open it again.

Thanks For the Support.
[8525, TyTN, MDA Vario II, JasJam General] MikeChannon:
It'll work without it. It's probable purpose is to damp out extraneous sound and vibration entering the microphone. But just to satisy yourself, why not phone someone and see that they are getting reasonable quality sound at their end. Otherwise I think it probably only makes the smallest of differences and you should be OK to carry on without it.

FIXED!!!

I bought a second hand JasJam for my son about a month ago & fell in love with it, so decided to try & find myself one. Well I did, but it had significant whitescreen problems so...

Fantastic work, I combined everything I've learnt here...

Dismantled the phone, cleaned every contact with wd40, placed foam tape on the highlighted areas & placed a small square of cc plastic under the square bit of the dpad...reassembled and all buttons work and, Yay, not a single whitescreen in a week!

Thanks soooooo much.

Rubber Thingy

You are much right about the microphone protector, while talking with the speaker on the person i am calling hears much louder sound and cant hear me properly so this rubber thing should be in there.

But Naaahhh!!! I am not going to open it again. At least will enjoy it a week or two.
[8525, TyTN, MDA Vario II, JasJam General] hiltinuts2:

Just wanted to say thanks. I've been getting the white screen for months and had to start using my old non-pda phone (yuck). I woke up this morning convinced that I needed an iPhone but decided to check the ole XDA forums for help before I left the house. I came across this thread and was able to fix my phone.

Thanks brotha!

Ah, one more note... I used thick-ass electrical tape rather than the foam. Also, I didn't have a torx6 so this gave me an excuse to head down to RadioShack and pickup a sweet micro driver set. Anyway, thanks again!

White screen fix and explanation

I have been mucking about with this problem for quite a while now on my SPV M3100 and I think Coolsbdave has hit the nail on the head!!

The white screen problem has always centred around that area ie. squeezing or putting foam on ect.

I have just tried his heat application trick and it has worked to a degree but I carried out the procedure without flux but it does work!! I am waiting for the delivery of some alcohol based flux so I can do the job properly.

If you take a look at the two attached PDF links that I have found you will see that the manufacturer of the Xilinx chip admit that they have F####d up with the soldering process on this chip and that just about clinches it for me, now I'm no great techie but I think this meens lots of dry joints but if anyone can give me a laymans interpritation them please send me an e-mail.

I will let you know how I get on when I get my Flux.

One last thing, sorry if this is a rubbish post but it is the first post I have ever done so give me a break????

RTFM! A note of caution

Mistake #1!

I tried this using my heatgun but unfortunately I'd not read the instuctions properly & heated up the pc board without peeling off the button plastic! Needless to say, I found that the adhesive plastic had shrunk & most of my buttons misaligned. I then peeled off the distorted tape, peeled off all 12 buttons & carefully aligned them in place then stuck a strip of electrical insulation tape over the buttons & board. I reassembled the board & tested, all the buttons were working fine. This is where I should have reassembled the rest of my Hermes & said "Well Done"!

Mistake #2!!

Now I noticed that there were 2 rectangular cut outs on the original adhesive strip, so I removed my board again & proceeded to "carefully" cut out those "rectangles" using a sharp blade........duh! I found out after numerous re-assembly & disassembly that I'd cut through some minute tracks too. Now none of my front buttons work, neither does my blue, orange or green lights. Time to shop for a new board huh?

The buttons on my Hermes stopped working but its only the 8 buttons that surround the D-Pad (left and right soft keys, call and hang up buttons, Start, Internet, Messaging and ok buttons. All the others work fine and theres no white screen.

This originally started on my Orange WM6 Rom and still the same after flashing HardSPL, flashing new Rom and Hard Reset. I have taken the phone apart numerous times, cleaned connectors and adjusted the tightness of the screws to avoid warping but to no avail. Also I have noticed a few times that the phone goes into the dialer screen by itself sometimes, but not all the time.

I know this isnt a Software problem so just wondering if anyone could give me the benefit of their experience. Thanks for any help :)

Happens to me every so often... especially after I drop the phone. Screen is fine but the whole dpad doesn't work.

Everytime I've had to take everything apart and reconnect the dpad connector, and now I've put in a piece of thick paper to further reinforce the connection.

You might want to dig out one of my posts where I described how I further "propped" the pins to try to get a better connection with the socket.

Hope it helps you out... good luck!

The strange thing is that the D-Pad itself and center button work fine no problems at all its just the buttons to the left and right that dont work.

Thought it might be a software problem but a new Rom and Hard Reset give the same problems.
