You'll probably have a lot of trouble getting that back on, are you rooted?

youll have to replace the entire main flex cable the power button is attached to.

wanted htc wizard main board

I broke the screen on mda and purchased a replacement but I think i fried my main board during the installation of the lcd. Is anyone selling a mainboard for the wizard or know where I can find a mainboard? I have checked on ebay and have found broken phones with bad usb connectors or headphone jacks. I don't need that. If anyone is selling a mainboard for the wizard as well as the housing, as long as its in good condition, please let me know. Thanks --> Mistawright
Are you sure it's dead??

I've just received a new screen for mine from HK. When I first put it in all I could get was a white screen, nothing else.
After ages of stripping down etc I found that it was the screen connector causing the grief - tape it down with some electrical tape and away it went.
Got versed in the art of connecting the screen to the main board and holding the battery in place at each stage of the re-construction to ensure it was still working.
I dropped mine and had vertical lines on the right side of the screen. Now, with the new screen in, initially it was fine but has just started wavering a little on the right side, so I may have had more than just a screen issue. Still as long as it lasts until my Kaiser arrives from T-Mo I'll be happy.
So are you selling a mainboard or not? If you are not what was the point of your post?

The point was in the subject of the reply: ARE YOU SURE IT'S DEAD?
I offered help based on my experience changing the screen and questioning wether your mainboard was really dead or not.
But if you don't anybody offering advice and only want to buy another mainboard without really checking if yours is dead or not then I'll shut up.
lets start from the beginning.
1) I broke the screen.
2) the phone would power on but cracked screen.
3) I bought a replacement
4) after taking the phone apartment and replacing screen phone does not power on
5) Amber light does not come on on phone when connected to charger.
Instead of suggestions like the topic of the thread says I'm looking to purchase a working mainboard or a phone with a cracked screen that works at a decent price.
Hi,
Did you follow any replacement doc to do the job? Or you just started alone? I asked you cause I got a LCD for my friend and together we replaced it without any problems. Everything is working fine! Remember that exist many pitty hardware parts during the process you should care about it. If you missed or have broken one of them, you'll probably fried the main board or similar component!

[Q] HD2 Screen Trouble, Looking for an answer to buy the right part

Greets all,
I know probably this is the wrong section but I thought I would get a quicker response to my dilema. I was testing out my rom on my Test HD2 phone (I have two of them) and this one has the infamous end key issue, and tested my patience, so I read that if you use a very small flathead screw driver and push a certain place, you can get it to unstick, being that I tried all my methods that usually worked, I decide to try, well, the screwdriver slipped under the button part between the end key and the back key and screwed up my screen where I have all funny colors all over. So I was wondering if any could tell me if this is a LCD problem or a digitizer problem. There is no running liquid on the screen. The screenshot below is exactly what my screen looks like, and I want to buy the replacement, but I dont want to buy the wrong part and waste money, so can someone please let me know what it is that I have to replace? Thanks!

Its definetly an LCD issue, anyways not a major issue, as long as you can dismantle the phone and clear up the area btw the LCD and Keypad, i guess it should be back to normal
When you say Clear up the area, mind clarifying what that means? I can dismantle the phone, at this point it would probably be cheaper then sending for repair especially that its most likely out of warranty anyway.
I'm pretty much under the impression I am going to need to buy a lcd/digitizer combo to fix this. Unless I dont have to, cause like I said there is no bleeding and the phone works fine (minus the touchscreen issue caused by the end key) I can navigate thru the phone using droid explorers Screencast.
well what i intened to say was that there could be particles of dust or debris that is causing the LCD ribbon to come out a little, Coz i had a similar issue with "Dead touchscreen workin hard press end key " , later when i dismantled the phone and put it back again my screen looked exactly like yours, all i had to do was open it again and fix the LCD flex to the Main board properly thats all.
on a side note:
Well the touchscreen issue eventualy died all together, and i now have a replaced LCD from HTC and the screen is dull

[q]mayor problems after replacing screen wont boot[19 jan]

Hi i have a htc hd2 with gingerbread, my brother replaced my screen and it work fine the first time with the only problem that you see light in the corners because it didnt fit properly to the frame,
2 he tried to fix it so he used some glue when i turned on it freezed when booting and the color white was showing pink
3 he took it apart again to put it like the first time and it work but now the speaker stoped working so i used it like that for 3 weeks
4 then i told him if he could check the speaker so he took it apart again with no luck and now it freezes again when booting we have tried to find the problem with no luck
do someone have any clue for what is causing the problem please help me
another thing since replacing the screen the first time you turn on the phone has to be with the ac cable because it wont do nothing with the on button after that the button works fine
hope someone can help me and sorry for my poor english
it seems like you might have a loose cable connection somewhere, like the loose flex ribbon or broken sockets. Your only bet is to disassemble your HD2 and assemble it,but this time around, you might want to do it according to proven methods and go step by step. Refer to the links below to help you:

http://pocketnow.com/hardware-1/official-htc-hd2-disassembly-assembly-training-videos-leaked
if proper disassembly and assembly do not work, then im afraid you have to replace your flex ribbon or get a new screen. it is often hard to troubleshoot what exactly is causing the problem unless you see a visual break in connections. take a really close look at all the connectors that are involved with the screen: the locks, sockets and cables.
do try the above and good luck. hope this helps.

HD2 (wanted spares/broken phone/advice) Please help !!!!

Hey guys just wondering if there is anybody in Melbourne or Australia or anywhere for that matter that may have a old broken HD2 (preferably T9193) that i might be able to use for spares ?? I currently have one and have dropped it and now it's colours are up the sh*t i have done a screen and digitizer replacement and without any luck the problem still persists any ideas would also be greatly appreciated
Ps. if i twist the phone in oposite directions the problem goes away which leads me to believe that something has come away from the board itself i have looked and cant see a thing any suggestion would be greatly appreciated
Maybe mainboard connector, have you tried applying pressure to connector socket/ribbon with it stripped but screen, mainboard rigged up with battery & bench test it while applying pressure to mainboard connector/ribbon with insulated/earthed tool.
maybe abble to fix it if can find out exact point of problem but most HD2 faults need replacement parts to cure faults long term ...

[Q] Weird non responsive lcd

I have a EU HD2 with dual boot WP7 and android. The lcd is not respondig at all, all my hard buttons
work flawless, including the power, the light is very poor and when I plug the charge cable the
display flickers just a bit. I can answer and end calls.
This happend after the micro-usb port stoped working. I was uninspired to try and fix it myself,
I managed to fix it, but NOT with a glue gun because is much too difficult. I just put a
little piece of cloth on top of the micro-usb port,so now the micro-usb is pressed against the board and
makes contact and now is charging well. I was extracarefull...but something gone wrong:silly:.
I even sent it to phone service, even if the warranty has expired, they say that I need another display,
but they didn`t have any for replacement. I don` know if I should trust them...
So I ask you guys maybe u can help me.:fingers-crossed:
Sorry for my bad english.
I attached some pics
Thanks
PM me, maybe I can help you...:good:
