[Q] HTC One M8 No Backlight after screen replacement ! - One (M7) Q&A, Help & Troubleshooting

Hi there,
Here is my story :
First of all, i bought a HTC One M8, one day was very rainy and my HTC M8 was in my pocket, i was very wet and the humidity goes on my M8.
Ok after that arriving home, i saw my screen black, no more backlight, then the backlight screen flashed i was thinking it come back but no never came back.
I sent my HTC (under warranty) to HTC.
They said it's not under warranty cause it's water damage...
I was very angry about that, cause my phone was just in my pocket.. They propose me to pay 600 USD to repair the phone, i said no i don't want to pay the cost of the phone just to repair it.
They send it back to me, i ordered a replacement screen on a very known website for 100 USD with all the tools, i changed it, charged the phone and, started the phone, and backlight is always black, i can see the picture through sun but the backlight don't work !!
Can someone explain me where is the Backlight on this phone ?? Is it a mainboard problem ?? It can't be the screen...

What can cause no backlight on a M8 screen ? i already replaced the screen but seems to be the same.... what do you guys think ?

anything could be wrong with a water damaged phone it could be motherboard it could be the socket the screen plugs into.
you could have messed up installing the replacement ?
any way it goes your most likely going to need another phone

i think it's the socket... but i can't find a M8 motherboard, and i dont want to pay a motherboard for a bad socket
No replacement is OK.

Where to buy replacement motherboard for kaiser

Yup, just like the title says.
And before anyone yells at me, YES i did the search button but nothing...
I checked ebay, and for some reason no one has a motherboard... and I don't want to risk it with buying one with a cracked screen that might have a messed motherboard.
HTC wants to charge me $352.26 for a new motherboard AND lcd... when only the motherboard wasn't working (last i checked, the lcd was working... unless THEY did something at the repair)
I've seen this before in another thread. I believe the consensus was that there was no place to buy them except risking eBay.
Damn...
So how much do you think HTC would charge to repair the motherboard separately from the LCD ?

Replacement LCD

Hi everyone,
I replaced my LCD screen and digitizer at the weekend and am now having a few problems. The battery is draining really quickly, in about 30mins. Could this be due to a non oem screen or something? (got mine off ebay)
I am also having a few issues with the power button, there was a small amount of tape in place but im unsure if this should go below the switch or above. To prevent the circuit board switch from shorting or something?
Any help appreciated.
how much did you paid for digitizer?
well I got an LCD with digitizer attached for $43
I'm needing the same, how difficult was it to put back together,
taking it apart isnt a problem but theres that many parts I'm not sure if I could put it back together correctly
Can you tell me how many different variants of the LCD are used in the Diamond? or there is just ONE LCD w/ digitizer..? And from where can I get them for a good price?
Well to be honest, I have only had problems since I changed mine and the phone is now unusable. Its quite easy to put back together, but it seems really easy to create shorts that cause problems and I think the quality of the LCD I bought is far below that of standard and is using lots of power.
Have ordered another screen from somewhere else and will try that but think I will get a leo next week as then im due an upgrade
Would still appreciate some help with my original questions?
I bought on ebay both/LCD+touch screen/. Price is fine 36US dollars. When you buy only on of this you have problem with right connection between LCD and touch screen. Picture have little contrast but not tragically. Battery draining is same. Touch screen is more sensitive than original.

Maybe is problem with correct connect gps antenna to connector on board.
To update this I bought a new screen with digitizer from a US company and replaced the board that connects to the microphone and now more Diamond is as good as new.
Screen is as original and excellent quality

Hi,
screen is original.
what happened was, i enabled win mobile autolock, and then i kinda had a fit. It was turning the screen on and off for about 1 second each time, i thought it would stop so i waited about 40 seconds, then hit the reset button.
when the phone reset it still had an "imprint" of the windows mobile lock screen on the screen, as if it had "burnt" all the white areas onto the screen.
I tryed to screenshot it, but it didnt show in a screenshot so i presumed the screen was wrecked.
I have left my phone without battery overnight and it SEEMS to have sorted itself out, but im not sure!
Thanks in advance

Thought this was fixed but the battery drainage is still huge. The phone is now constantly hot, so have stopped using it. I have dismantled the phone countless times now as I thought there may be a short circuit but with no fix.
When I posted originally the battery was on 85% after 4 hours but then the next time I turned the screen on it was on 1%.
Its annoying as I loved my Diamond but now I just feel angry when I see it on my desk. Using an old moto flip phone at the moment which I hate, untill some shops get the leo back in stock. Tempted by the n900 also, any thoughts?
Hi,
I will change my Diamond's screen. Did you buy it online? If so, would you please send a link of the LCD w/ Digitizer that you bought. Thanks in advance

Phone does not switch on. Any way to access Internal Storage ?

.. to remove personal data and sell it for spares ?
As I understand there is nothing like an SD card inside, is it embedded to the motherboard somewhere ?

Hi Hertc,
I had the same problem and i had to return it back to Bestbuy guys and atleast i had insurance on the phone by bestbuy so i got the new HtC touch Diamond phone by Best buy. HTC people said its a bug in the motherboard and that is not repairable.

Mine is not covered by the warranty (hard floor impact ) and the price quoted for the MB replacement is more than they ask for a used Diamond-2 in excellent condition on eBay.
I will probably have to break it apart and sell screen, battery etc. separately destroying the motherboard .. do not want anyone accessing my personal details, could cost more than what I can get for the whole broken phone ...
Anyone needs a replacement screen ?
Need the screen
Hi. I actually do need the screen, got HTC Diamond as a gift, does turn on, I can hear the sounds but no picture. I am guessing I need the new screen. I would need that screen.

compatibility....?

hi my friends!
i found a mainboard replacement for my GT-N7000...
my phone is white, the replacement phone is black.
i can use everything from the black one, both are 16Gb edition, both GT-N7000 model...
my question is: is there any chance that the mainboard from the replacement phone not to work into my own?
help me!
If your pretty much sure 100% that the replacement phone (which is black) is for the international unlock N7000 one.. then I'm pretty much sure also that the motherboard of that will and is 100% compatible with your white Gnote.
Aesthetically. the only diff between your white one and the replacement one is the colors of their casing... but other than that... I'm sure internally all are one and the same
the replacemetnt phone which is black has the screen broken, but if you call it it rings, but no can answer or anything, as the screen is broken.
is a GT-N7000 unlocked phone... my fear is that chance of incompatibility of that mainboard on my phone (which all is good except the mainboard...)
if the only problem on the black replacement one is the broken screen itself... then I'd say the motherboard of that is really compatible with your white Note.
By the way, where are you buying the replacement? if it's on Ebay,just a word of caution... don't rely too much on what the seller has to say... who knows.. some says that it's only the screen itself that is broken... but when you finally receive that unit... there might be something more to it that is broken.. you'll never know...
just a piece of advice....
no, not ebay...
just a guy has it and i found it on one of locally forums.
i see it and tested personally the black Note (replacement) and beside the broken screen, i was able to call the phone and it rings, vibrates, but i can't do nothing because of the broken screen.

then u should change the screen. otherwise with "cannot do anything" on your notes is equal to not owning notes.
no, you did not read the whole topic....

then, if you trust your instincts then go for it.. Again let me reassure you... there's no difference between the white and the black N7000s... only the color of their casings.. other than that.. internally, they're all the same.
thank you, i really hope you are right...
maybe i will have my Note back...

[Q] Should I buy a broken One m7

I saw an ad for a broken One m7 and the guy says he dropped it and the screen is dead, so I was thinking I could replace the screen and make a buck. but before I do I wanted to ask a question... He says when he starts the phone some lights go on and the screen stays black, on my m7 it vibrates and starts up without any lights. could this be a sign that there is more damage than just the screen and digitizer?
Thanks

Honestly, if you are asking questions like this you should not buy a broken phone. Only buy if you are sure you can repair it and know what is damaged exactly.
The M7 can be found for less than 250$ New on ebay btw. not sure you'll make any profit after paying for the phone, the replacement parts and the time to fix it. There are also some risks when opening that phone, many member here sucessfully repaired the M7 themselves and other damaged the phone when opening it, even if they did it very delicately.
Imo doesn't worth it.
But still worth to buy one for 250$ if you want to have one for yourself.

If I buy it it'll be for $60, that's why it's so tempting. but I will definitely put a lot of thought into it before I jump on it.
Remember if you are going to repair it properly, you'd probably want to buy a screen assembly + housing. Its almost impossible not to damage the phone when you open it.

60$ for a broken phone + 50$ for a screen assy + 15$ for a new housing (almost always damaged when opening like said) = 125$ + parts shipping, So lets say 150$ total and you are still not 100% sure it will work and won't have other issue like the infamous bad (purple) camera (25$)" Phone is used and will probably need a new battery, another 15-20$.
So at least 150$ + your time and still not sure it will work (might not be a broken screen, maybe a broken mother board), you might damage other parts when attempting to repair like the tiny flex cables. add an extra 75$ and you can get a brand new and carrier unlocked M7.
I'm glad I asked before going a head with it, thanks guys.
