I blown away most dust particles with dry air when assembled back this unit (maybe any microscopic dust have remained there but could not be seen :)).

Yes, I do know what is a white LED, how it is powered and how it works. I just need to know what is the type of LEDs used by HTC?

Now, I took a photo of my trouble. There are 8 LEDs and 2 of them was re-soldered very bad quality and seems these LEDs have slightly other shape, maybe even other type, as You said. They are powered by 2-wire ribbon soldered to main flex display cable which connects to mainboard through regular connector (see the picture no.1) and all 8 have the same apparent brightness for my eyes (if some of them was burned they should become blueish white with reduced brightness but all of them are normal bright white, just not enough brightness = not enough current from power source). From this picture I see that LEDs are connected in series, and we know that it is easier to power a bunch of LEDs connected in series because you have to control their current only, but higher voltage is needed. That's why I supposed power source failure, not LEDs, because higher voltage is present here (about 24..28V) if we have a current limited PWM LED power module. Till I did not took any measurements it will be only a hypothesis anyway :D

When I'll have access to an oscilloscope, I'll continue further research, may be tomorrow or on Thursday. I can spend some money and buy a new LCD but I have to be sure that this is the problem :confused:

In the picture no.2 You can see "white spots" (upper left corner) on thin polarizer film. This film is Aluminum coated on the other side and these scratches are "etched" in this Aluminum coating, I have not idea how it was happened, can suppose only that was some condensed water or sweat if the phone was carried in pocket. In reality they looks like bright scratches under picture. That and a few dark dirt particles was the reason why I disassembled my LCM.

EDIT: Today I observed strong overheating of a small IC under LCM connector (see picture no.3), may be it is the LED driver? Somebody knows what is this IC?
[HD2 General] pvii:
I spent some time and did a little research:

1. Replaced LEDs are the same current and brightness (about 10 mA, brightness it's my opinion :));

2. When connected to an independent LED driver (Boost, PWM, current limited) they work very bright at 10 mA, as intended. But when connected to phone's LED driver they actually will work at approx. 20-25% brightness and at voltage drop is 19V (must be 3.2*8=25.6V).

To verify that LEDs are OK I connected a flex cable with six white LEDs from SONY PSP broken LCD (LEDs are absolutely the same as in HD2 LCD by voltage and current) and measured voltage on whole LED bundle. It was 15.2V (must be 6*3.2=19.2V). I vent to conclusion that LEDs and LCM are OK and is time to start troubleshootong M/B. These measurements proofs that LEDs are driven by current limited boost circuit, as current is the same and voltage caries in function of LEDs stack. Open-circuit voltage is about 38V, enough for 10 LEDs.

I did a backtrace of LED mains and came to a little problem: the PCB is a very multilayer, about 4-6 layers and a lot of routes are hidden in middle layers, it is very hard, near impossible to trace full schematics of diving circuit, but a little part of it is clearly visible.

In the my last post I did a mistake. That IC I tought is overheating was not overheated, there was some flux traces but it's temperature is ok. More ov that, this IC is not related in any way to backlight LEDs, seems it is digital magnetometer (compass). I thought that will be logical to place drivers for all LEDs all together, near the battery connector and power controllers. And it is! In attached picture no.1 we can see power outs for backlight LEDs and flash LEDs. It's a regular boost PWM scheme, where output power module is an IC which integrates a power MOSFET, current limiter and programmable PWM regulator with digital interface (driven in my opinion by I2C or SPL from PM7540). PWM is a IC coded as BZR 9AK, did not find any info about it in GOOGLE or other search engines :(

Summing up, problem comes from: (a) PWM IC or (b) interface between PM7540 and BZV-9AK and I do not have any idea how to fix it.

Now about Your schemas. In my head came a similar idea and it works, but I powered my phone from a lab power supply which don't discharges as battery. I connected LEDs as showed in picture no.2 and it works. I don't know how it will work when battery discharges, I think it will dim a lot when battery charge will be 40% or less, need to test it. But it isn't a good fix, additional wires will make assembling of this phone a little puzzle :D. You will need to use soldering iron to connect/disconnect LCM module. It is still a temporary solution and I still wondering why it happened and where to buy that IC marked as BZR?
[HD2 General] motoi_bogdan:
i haven't got a disassembled hd2 to check these components so i must rely on your findings.

I also mistaken in my above schematics :D they will not work in a serial connection for the led's. Simply because when taking power directly from the battery, we'll have only 3.7-4 volts and not the 25 volts required to drive the serial array of leds. It could have worked if the leds were placed in parallel.

About the step up converter, the inability to drive the load, coupled with the collapse of the driving voltage when the load is connected may suggest the BZR IC failure - more precisely the mosfet transistors switching the voltage to the coil. I have absolutely no idea why the frequency generator part should fail (or whatever components determine the frequency of the PWM) I haven't seen this type of problem too often. But more probably the "power" components (chip containing power mosfets) have failed - to some degree.

I guess there won't be direct replacements, you should look for a compatible chip (pin to pin would be ideal) but.. what about the coil and other components...
[HD2 General] pvii:
Yeah, I think so that BZR is partially broken as I wrote in my last post and still looking for compatible replacement but no luck yet :(

All external components like diode, capacitor and inductor are intact, no signs of burn or overheating.

It's the ad networks that are used by the app.

I emailed back and forth with the CTO of DI Radio (DI.fm, SKY.fm) and it basically came down to that while DI Radio wasn't looking at my cell tower location, carrier name, and ESN, the ad network was to track me, but he said they wouldn't change their ads just because of that.

However, after this fiasco with Pandora... Maybe they will.

I really don't see an issue here. It's way overblown. It's the price you pay for an ad-supported app, and I think it's a small price.

So they want to know if I'm male or female? Yeah, I don't need to see Tampax ads.

They want to know my birthday? OK. I give that out at Chilli's to get a free order of nachos on my birthday. And I don't need to see Depends ads for another 40-50 years or so (I hope).

Location? Well, OK, I can see that this makes people a little uneasy, but if they want to send me a coupon when they see I'm near a strip club, I'm probably grateful to receive it.

This is NOT a thread where I have a fix for battery usage problems on CM7; I'm looking for a fix. Ladios's kernel is not fixing my battery issues. I'm running Ladios's modded RC4. It's not that I get battery drain while off; while actually using the phone's internet browser/doing anything other than texting it'll drain at faster than 1% per minute while browsing in 3G. Putting it in Edge is NOT an option, I did not buy a 2G phone. Any solutions?

Here's the thing man. Cm7 has new features etc that take up more processing power which = battery power if u trace what is actually being used.. common sense. Sure cm6 may have outstanding battery life we all know that. However, It may seem small but did cm6 have the notification pull down Widgets? The theme Chooser app? Compcache support, nicer graphics? All of this plays a role. The more features were ***** and moan about NOT having leads to *****ing and moaning when we do have it. Add in the tweaking and time spent testing new releases and yea our battery will **** out. If we ran stock full time no Modding our battery's would run to manufactures spec minus a few lemons here and there that get missed by the phone company production line. Nothings perfect. But honestly give the battery a break. Just cause software is updated doesn't mean the battery magically can handle it. Hate the battery life? Get a new battery or a new phone.

[Windows Phone 7 Q&A, Help & Troubleshooting] OTD Razor:
Kinda hard to understand what you are saying, but I will take a guess at what you are meaning.

If you updated your phone to Nodo and forgot to dev unlock + prevent relock via the registry you can go undo your update by using the backup function in the Zune software... so long as a backup is made. From there do the dev unlock and take the steps necessary to prevent relock, then update to Nodo. Once you are updated your phone will still be unlocked and will not relock.

I did this in my Focus.

Does the Focus come with a memory card?
[Focus General] KonAitor:
No, but it comes with a micro SD Slot.

However, there are no officially certified cards that work with the focus. You can look at the sticky of this forum to see a lit of cards that have been tested by the members.
[Focus General] MartyLK:
Yeah, I gave the sticky a good looking and saw it works with the Samsung 16GB C4 card. Good enough for me. Just needed to know if there was a card in it when I get mine so that I can install one before accumulating data and stuff.
[Focus General] MartyLK:
Popular formatting method?

Is there a preferred method of formatting the cards, or will WinXP formatting tool be sufficient?

Thanks
[Focus General] FishFaceMcGee:
All you'll need to do is put the card into the phone, and then do what's called the three-finger-salute. You'll need to hold down the power, volume-down, and camera buttons until it asks to do a hard reset/format.
[Focus General] foxbat121:
You need format it inside the phone together with the phone storage, e.g. hard reset/format the entire phone with the card inserted.

Also, if for some reason the card gives you issue with the phone and you decide not to use it anymore. You need to re-format the phone again. And your card will be useless unless you have a Nokia phone running Symbian OS. That's the only device that can re-format the card that is pulled out of WP7 phones like Focus.
[Focus General] MartyLK:
Using a Sandisk 16GB C4 card. Formatted in WinXP, inserted it into phone and did the "Volume" + "Camera" + "Power" button combo to format in phone and initialize it.

A little off topic...I haven't had time to use the Focus yet. I had to make a quick run to a local mall to have the Ghost Armor put on the highly scratchable "Gorilla-Glass" screen. Been reading horror stories about how scratchable the Focus' screen is.
[Focus General] MartyLK:
I don't know if it's a problem or just how the Focus is with 7004 firmware but, sometimes it acts funky about loading the main screen...where the tiles are. Sometimes, generally after running an app, when I go to the main screen, the tiles are slow about loading or showing. One time I had to reboot and then they all loaded right. Other times it take a few seconds to stabilize.
[Focus General] foxbat121:
IIRC, slow loading home screen is a typical symton that the SD card is not working out well. Even after NoDo update, it will be the same. Microsoft did very little to fix the SD card issues. That hints it is the Samsung problem.
[Focus General] aksmurf:
Since I've got the nodo update, all in all the phone is more stable, but I have been having the same problem with the main screen taking a few seconds to load, however its only when using the xda app and nothing else. Using a Kingston 16gb c4 sd card as well
[Focus General] MartyLK:
I notice the slow main screen loading issue when the phone is tasked with other stuff, like installing apps or updating email or news and such as that. My HD7 did the same thing from time to time. But my concern is with the installed card. It's a class 4 card and the experts are saying it isn't about speed or throughput but the ability to keep up with WP7. The class 2 cards may have slower read/writes times but they seem to be more capable of keeping up with WP7.

One thing is sure, I won't buy one of those highly over-priced certified models. I'll wait till the larger cards get certified and buy the common version...the one without the expensive WP7 logo. :D
