If you didnt drop it or took it for a swim i think you might have a broken/loose flex cable, that happened to me a few weeks back (it got ripped in half) and unfortunately the flex ribbon is nowhere to be found, i had to buy a slide with a broken screen on ebay to take the flex and replace it on my phone.
i might be wrong but if the keyboard is lit up then this is the only explanation i can find...

One X solid red light after (attempt to) repair

I dropped my HOX and I got another HOX with working mainboard. I replaced it and everything worked except for very faint backlight and flickering. So I disassembled the phone and put it back together again. Now I can't start the phone anymore and the solid red led burns when connected to the charger....after I connect it it flickers one time, very fast. Does anyone have an idea what it could be? So pissed of right now...
Hi, if you don't have any power at all eg no vibration or lights on three bottons at the bottom, it could be that the power connecter is not properly plugged in. follow cabble down from power button, plug is hard to get at unless you unstick power button from cassie.
If you have some power check lcd is working by using a bright light near the screen and closely checking to see if you can see anything, could be backlight not working.
just my 2cents
feel bad for ya!

Okay, I have experienced the same thing and I'll tell you what I did to fix it. I dropped my HOX after owning for only a few days and the screen was cracked. I ordered a replacement LCD/ screen digitizer part and took it apart. One of the things that I found was that there was adhesive everywhere, including adhesive on the connection to the battery.
After it was taken apart, I attempted to test the new screen. It was then the LED turned solid red and the phone would not power on (even after 10 minutes of charging). What I did was remove the adhesive from he battery connector and disconnected the battery completely. I plugged it back in 10 seconds later and it turned back to flashing green (which is normal because I had several missed texts).
So my solution was just to unplug the battery and it worked just fine. The hardest part about this whole process was putting the cover back on, especially on the side with volume buttons! Hope that helps.
I have exactly the same problem. The difference is that now that I took it off charge, the red light is flickering on and off. I cannot get the display to show! Please please help.

Replacement LCD problems

Hi,
So I dropped my UK one X the other day, the fall was so bad the LCD popped from the frame and tore the ribbon cable for the LCD.
Now, I've ordered the replacement screen and after a strip down and rebuild which lead to removing the battery the new screen is now blank (phone charges and seems to power on)
After doing a quick search on this it is all pointing around syncing the screens - which I cannot do due to the broken ribbon cable on the old...
Any ideas how I can get this working without the syncing process?
It is rooted with a custom rom if that helps.
Thanks, Matt
Anyone? Kinda desperate.

Screen is "black"

Hello!
I hope somebody can help me, I tried to solve the problem by myself but I ran out of ideas what could be wrong. So to start with, i have replaced a cracked screen with a new one(lcd+digitizer). Everything was working fine after assembly, so I gave the phone back to the customer. Yesterday after 3 weeks of usage, he came back claiming that the screen isn't working anymore and that sometimes the screen was black and the other second was working. So I gave a look, but the screen was working(suddenly again), only the colours were a bit funky(probably the screen flat cable is the problem or?) So I opened the phone but nothing was wrong with the cables. I also cleaned the connectors with air if there was maybe some dust. Then when I assembled it back, plugged it in, to charge it, the battery was on screen,saying it is charging and I thought the problem is solved, but when I turn on the phone there is still nothing,blank screen. What could be wrong? The screen must be working because otherwise I couldn't see the green battery when charging the phone while off.

[FIXED] Multiple Blue Screen Glitches Led To Phone Bricking For No Reason

Before the phone turning brick, I was having these weird blue screen glitches that took almost half of the screen. It would stop after a few seconds, but this type of "glitch" happened a few times. 2 days later, I was on the home screen and the phone screen turned fully blue. It didn't go away so I took out the battery. After that the phone turned on with the boot logo but then shutdown itself. Now the phone won't turn on, charge, go to recovery, or go to download mode. Is there any way to fix this? (I don't have insurance on this :/)
(FIXED) It was "fixed" by leaving it charging, but now the blue screen showed up again. Now phone is probably damaged internally :/

I did flash a rom, but this was like 2 weeks ago. I wasn't having blue screen glitches until 3 days ago.

There is no solution to blue screen glitches.it is caused by a current IC that draws more current and heats up within 3 5 seconds. I lost one mobile in this game. I feel sorry for you too, it is hardware issue and won't get any repair.

What is "IC"? Also the phone turned on finally last night but when I connected it to a charger the same blue screen happened and now I can't turn it on again. Thanks for the information though

IC means integrated circuit. It's basically an electronic chip.
BSOD Fix
I had the same issue and was able to fix it temporarily for a few weeks but in the end I had to replace the motherboard from a donner phone. I had a lg d850 att and swapped out the mother board with a d851 from T-Mobile phone I found that had a broken screen and it worked fine after some tweaking. As far as your temporary fix (maybe permanent in your case idk) I took out my motherboard and put it in the oven at 385 degrees and baked it for 10 minutes let it cool off and reinstalled it. Phone came right up and worked like normal. Use some aluminum foil balls to put the motherboard on to keep it off of the surface in your oven that you put the motherboard on. That's it!
