I bought an 8525 used off ebay, with a broken screen listed as its only defect. I bought a replacement screen and installed it, but still no dice. I can plug the phone into my PC and it's accessible through Windows Mobile Device Center. It even let me upgrade the firmware to the official WM6 ROM. Still, no video.
I read in a thread here that if you plug in the phone to USB with no battery in it and a red light comes on, it means the hardware is OK, and with a battery in it if the light flashes red then goes black it means the battery is no good, and that the screen won't light in this circumstance.
So I bought a *brand new battery*, and plugged it into the phone--it still flashes a red light and doesn't turn on the green charge light, and the screen still doesn't light.
Can someone please offer some advice? Obviously the device itself works because it connects, syncs and takes software updates, but without a display it's as good as dead anyway. My new screen came with a new cable as well, so I'm pretty sure it isn't the problem.
Thanks!!!

From what you've described I don't think a broken screen was the only problem with the phone and that some of the internal electronics are defective as well.
I tend to agree, but I'm looking for a starting point to look at next. As I mentioned, the device works fine aside from the screen, so apparently there is something more, I'm just not sure where to look.
Thanks!

I had a problem with my LCD and tracked it down to a bung flywheel... I have no idea why that affected the lcd but I got a 2nd Hermes off ebay and replaced the flywheel off the old one onto the new Hermes as I liked the feel of the older flywheel better. This caused the new LCD to turn off too. I replaced the flywheel again and it worked... Have had no problems since...
Cheers...

Thought I'd try talking whilst going for a jog and managed to get some sweat into my XDA Mini. The result: the LCD still operates, but the backlight is broken.
I took it to a repair shop to see if they could repair it but they say I need a full new LCD - not so cheap. The guy seemed a bit dodgy so I thought I'd double check people's thoughts here before I go and spend the $150 to fix it.
I'm sorry if I'm insulting your intelligence, but have you tried holding down the power button while the screen is on? The backlight can be toggled on and off by holding the power button down a few seconds.
Just making sure!
(Eg. Check your floppy drive before you decide that the hard disk is dead - store attendants can actually forget things like that)
Haha,
Yes I have tried everything relating to normal backlight usage, including a hard reset.
I know the backlight is stuffed because for a while it would turn on for a sec before turning off, then finally it went kaput.
Well the backlight probably is stuffed. And $150 is a bit steep for a new screen, but I doubt you will find any better - though if you want try eBay. I just searched eBay US for 'xda mini LCD' and got a range of LCDs from $70 to $100.
The installation isn't too hard, as long as you're careful - it just involves opening the Magician (which takes patience, but isn't too hard or risky), unplugging the old screen, detaching it, and installing the new screen.
Darn,
I found a screen for AUS$115 delivered on ebay.
Is there any way I can tell if I have the black or yellow screen connector without opening the phone up (I'd prefer to have to open it as few times as possible). My guess is that it would be one of the black ones as I think it's an earlier model.
Hey maximus, I know it's been a while. Did you fix your screen? I've got a Trinity with me (also known as Dopod D810) and I put a new screen into it. It worked, but after a few weeks, the alignment went off and would not reconfigure no matter what I tried. Then suddenly, the backlight went dead but the LCD still worked (I can see the content on the screen if I shine a torch on it). I'm an experienced phone repairer but I thought I'd check to see if you did anything to fix your original screen.
I've got the phone open - the connectors are fine. I've tried applying light pressure to the sides of the LCD, hoping that maybe it was just a loose connection inside the LCD, but to no avail.
Looks like I'll have to buy another LCD
hey i'm have=ing the same problem !
there are not any option but new screen
Do I blame the onboard video or the LCD itself for this problem? I've taken the phone apart and re-seated the motherboard connections, which was no help. If I connect using EveryWAN the phone appears to be working fine, in fact I flashed the T-Mobile ROM and than the Button ROM thinking it was a IPL/SPL issue. Even if I try to start in boot loader mode the screen still looks the same.
Just trying to decide If I need to replace the motherboard or the LCD.
Thanks,

Screen seems intact without any damage visible, no cracks or out?
Had this problem once with my old Universal, was the colour transfer wires that were loose, but pretty sure the Uni is totally different to our wizards.
Prehaps open her up and see if theres anything thats loose prehaps.
I had it opened and re-seated both the connecting cables, but no luck.
Ive had this problem with my wizard .. i couldnt find a solution. tho i didnt really try very hard. Basicaly just picked up another one on ebay for like £30 seemed cheaper than spending the time and effort fixing it. I think mine got progressivly worse. It used to do it occasionaly and now just it as soon as its switched on
i have a same sort of problem...
left of the screen fills with lines and the whole screen fades to white.
turning on and of the screen via power button takes it back to normal but then it happens again.
noticed it only happen in portrait so i have to set it to landscape all the time
for some rom and spl's it happens just a few times a day and others i cant use it in portrait.
If i find a solution it might be working for you to
Fading white screen of death
Could be the battery. Have you tried a new battery?
Solved.
The LCD itself was bad.
Okay, I already have a fine working black G1 with a broken camera ribbon, the ribbon is a ***** attaching to the motherboard always seems to come off during install of the motherboard, and it force closes the camera app when started. But today I got a white mint condition G1 with water damage for free. The white one does not power on and looks almost brand new.
I want to swap out the guts and install my mainboard, camera, baseband, utms in the white one and use it. Now 2 concerns, would the screen and keyboard be fine?
and also when I am reassembeling how would i do the camera ribbon? its always a ***** cause it seems to come off when i put the motherboard in the brackets.
thanks guys.
Did you check the service manual that's floating around? Not sure if it's in there but it's worth a look if you haven't checked already.
Alright, I've managed to transfer everything from my phone onto the water damged phone except the keyboard and the screen and when connected to a charger, it lights up red led and when i take it off the keyboard lights stay on and so does the red led. it stays on. Now my only concern is what is the problem now? I've managed to put back together my phone and it works perfectly fine.
Hi all, I was going to sell my HTC touch HD to a mate of mine and due to many scratches on the casing I purchased a new case & chassis. After following a guide on the internet, as I removed the screen I caught a small ribbon cable believed to be the light and pulled it slightly out of the clip. We replaced it and put the phone back together and it looks like we have broken the screen as you turn it on the phone vibrates but we get a small white blob near the end call button. It also appears the phone no longer charges although the amber light appears and you can turn the phone on. I think the phone was working because if you press the buttons the phone vibrates, but now nothing happens. Is my best bet to sell the phone as it is or shall I buy a new screen and attempt another repair? its £38 for a new one and I dont want to waste any more money.
Use a program like MyMobiler to check on your desktop pc that your device is working, and that you are sure the screen is faulty. If you really have broken it then a replacement is your only option.

cheers thats a great idea.
Does anyone know about why I may be getting the charging problem? Is it because the ribbon inside the phone might not be earthed 100% as I removed the tape holding it down
The phone was working fine but my son said the touch screen was working off and on. Now it doesn't come on at all. I am trying to find out if the phone needs a new lcd screen or maybe it's just a cable causing the phone not to work. We tried the reset, took out battery/sim card and still nothing happens on the phone. The screen is still a grayish white. It seems to be charging. When we put the battery back in it vibrates like it wants to turn on. Any help with this problem would be appreciated.
Still bad
Hi, hope you fixed the phone, sounds like a bad flex, you can get a new one from eBay (about 16Dlls).
Changing the flex isn't that difficult but you must be VERY CAREFUL or you can damage some phone internals, there is a service manual but i think you cant watch some disassembly videos on youtube, they're better.
