Cliffs Notes version:
Broke the glass on my Rezound but the digitizer and LCD were working fine. While replacing the glass I broke the LCD, so I bought a replacement from ebay.
Now the new LCD will turn on to show the initial HTC screen and then it goes blank...no backlight or anything else on display. I can boot into hboot and fastboot. When I try to boot into recovery I get the blank screen. Did I get a bad LCD, or is there more to it than that? I managed to find the broken LCD and it has similar behavior, so I'm worried I may have broken something else on the board while replacing components

make sure the rainbow cable isnt pinched anywhere and that it's plugged in 100 completely, ive had this happen to me when i first started to take apart phones with the Inc. even if it's a slight angle it will not make a good enough contact.

So, about 2 weeks ago, I got my HD2 off of Craigslist with a cracked screen. It worked perfectly fine with the exception of the hardly noticeable cracks. I knew I could get the replacement digitizer/screen for $40-80. I got my screen in the mail yesterday and, following the "YouTube" video tutorial found on this site, I......ugh.... replaced the screen....................I SCREWED UP BIG TIME!
First, I broke the ribbon cable for the Side "Volume Up/Down" buttons. Then, I broke the ribbon cable for the "soft keys." Ah, crap, but oh well. I figured I could use the touch screen for pretty much everything i needed to do. Well, while prying the cracked digitizer screen from the LCD, I went a bit too deep & peeled the tinted film off of the LCD. I thought nothing of it at the time. I'd already done enough damage. So the display would be a bit brighter than normal oh well.......WRONG! I put the phone back together and once I get it to power up, all I get is a white screen. I thought I missed something. So I disassemble & check 3 more times. Still a white screen.
Well, after all of this, the new digitizer/screen doesn't want to stay in place very well. So, being pissed off and curious, I pull it out and away and notice in the backside reflection of the digitizer that I can slightly make out the phone display. So, apparently the "Tinted Film" that I accidentally peeled off of the LCD makes images visible on the phone screen. I kind of damaged this film when peeling it off. Therefore, I am unable to put it back on. Does anyone know of a simple fix without replacing the LCD?
SORRY FOR THE "SHORT STORY LONG."
I was brainstorming and thought that maybe the film was polarized. So, I grabbed my sunglasses, which are polarized, and wearing them, I can faintly see the display. Anyone think maybe polarized window tint might fix my problem?
Hey man I have some electronic devices that need repair, can I send them to you to fix them?
SURE!
You can pay me in HD2 parts.
Sir i can only say 1 thing. search ebay and replace everything you damaged. only that way you will get your hd2 in perfect state.

I'd go one step further and say bin it and get a new one!
You sound just like me. That is why I never try things like that anymore. Hope it gets sorted but might be better looking for a used one.
I've got it functioning...
I found the film that I ripped off, put it over the screen and........I CAN SEE! However, the top half has lines through it. So, I must've damaged the LCD. The good news is that my phone is useable again. I just have to do everything via the touch screen and can't let the screen hibernate unless I have my charger close by. I'm just gonna keep my eye out for a cheap busted phone and eventually have a 100% phone again...
I sympathize with you. I broke HD2 while I was trying to check for loose WiFi card cable(cuz i was getting weak WiFi signals). The cable turned out to be fine but the external speaker stopped working. I opened it up again and adjusted some parts and it just got worse. the HD2 didn't power on at all. I tried fixing it but to no avail. I ended up sending the HD2 to a repair shop and was charged $170 for the repair. the repair guy said i messed up the power IC and the connector for the external speaker and he had to replace the power IC and resolder the connector.
I think I'm gonna stop trying to open up expensive phones. i was stupid thinking that since I have successfully replaced digitizer for my previous Palm T3, E2 and T5, opening up HD2 wouldn't be a problem. Should have known HD2 components are really fragile...

The best topic ever Thanks, dude!
My X2 screen has started to occasionally go very dark, like the backlight (if that's what it's called) is going on and off, if you look at the screen almost straight on you can still see whatever was on the screen. I have reset it and put a couple of different ROMs on it, but same thing, so it seems it is unfortunately a hardware issue.
Does anyone know what the part that provides the light (backlight?) is called and can it be replaced somewhat easily or is it not worth the trouble on a phone this old?
Let me know what you think please. Thanks.
I found a digitizer for $35 and a LCD for $50. I would think just the LCD needs replacing right? What is the digitizer?

The digitizer is for your pixel's if i recall. Can try to replace the LCD.
Specifications:
Asus transformer tf300t
display partnumber hsd101pww1 rev 4-a00
OS latest software version
I have replaced a lcd display a some time ago. The replacement LCD was working fine, but after a few months the replacement lcd display is showing a strange and wrong color gradient. It looks like old 16bit colors...
My hardware related question, could this problem be cable or lcd or mainboard related?
Yikes. I'd suspect a physical issue with the display. What do you see when you connect to an external HDMI screen?

When the hdmi cable is plugged between tablet and my tv, there is nothing wrong with output.
Today i have replaced also the flex cable, that did not help either.
Could the problem on lcd dispay be fixed? :'(

I'm speculating on the damage being with the LCD. I'm an IT professional (20+ years), so I do have a bit of experience here. One thing that's concerning is how the screen is separated, vertically, into the four bands. LCD screens are ridiculously delicate. I know from experience, having broken mine when replacing the digitizer glass.
LCD screens are typically very difficult/impossible to repair. It's cheaper/easier to just replace. I know this sort of sucks. Perhaps you can buy a replacement from a vendor that has a decent return policy. I'd use rubber gloves to handle the replacment (no fingerprints). Temporarily connect it. Problem gone? Then it was your LCD. Problem persist? (unlikely). Repack and return the replacement screen.
Good luck.

OK I have ordered a new lcd display, lets hope this will solve my problem.
Thanks everyone for your reactions.
(TL;DR version below) I have a BADLY cracked Rezound, which fell from my backpocket when I was taking my pants out of gym class and hit it smack right on the screen. I've looked for signs of a cracked LCD, I've never actually seen a phone with a cracked LCD, only digitizer, and I don't see any 'leaking' colors or discoloration, any dead pixels or anything, it's just a normal cracked phone. However, sometimes when I try to text, message, or write something, some of the buttons (Often the N and G button) doesn't work and it always presses the button next to them, I have to turn it in landscape mode for me to press the N and G buttons, but other buttons doesn't work, so it led me to the conclusion that certain parts of the screen does not respond. However, very rarely does the phone work perfectly, if not for the cracked screen, I can press every button just fine, and the phone doesn't press buttons by itself.
What does this mean? Does this mean the LCD is damaged? as far as I know, weird color display is the only symptom of LCD damage...will getting the digitizer fixed solve these problems?
TL;DR: Some parts of the screen do not work most of the time, phone presses button by itself, will replacing digitizer fix it?
If you have the insurance option and pay the 100 dollar deductible take it because I have read other posts were they have tried a replacing the digitizer and something else would go wrong like a burnt 4G card.

Nope, don't have any insurance, the Rezound is my second phone, with the original Motorola Droid being my 1st, and I have never dropped it so I was in over my head when I bought my rezound D: so is that a yes, that I need to replace my LCD, along with my digitizer??

Should not. If the display is clear with no lines or colors fading, digitizer is all you need.

Digitizer is all he would need, but would recommend replacing them both as a whole. Makes the process much easier, and isn't that much more expensive ($60 on eBay for a LCD + digitizer assembly). Don't have to worry about dust getting trapped under the digitizer when replacing it.
So my girlfriend dropped her s3 the other night , the screen stays off ( does not light up ) but the touch sensors still work, we can answer calls on it by knowing the approximate location of the answer button, any thoughts on what the issue is ? I would prefer to repair this at home rather than make her pay money through a shop, thanks in advance

It is easy to replace broken GLASS.
but i think you will need to replace screen.
If you purchase assembly of glass, digitizer and screen it will be very easy to replace by yourself.

The glass isnt broken, perfectly clean with no scratches cracks or nicks , it just wont light up;
i had the same problem once, had to be sent to samsung (or wherever) by the shop where i bought it
buying a display and metal frame (obviously you can't buy them seperatly) plus glass would have cost almost the same
i wanted to find out whether the screen still works and it's a problem with my motherboard or vice versa so i unscrewed all bolts to access where the screen is plugged in on the motherboard but i didn't have another s3 to do the same and check it :silly:
still don't know how amoled displays work so it might be possible that whatever's responsible for backlighting the display broke

My thought was that the backlight broke or maybe the entire display system is disconnected , I might just have to take it apart for an exploratory operation,
before it went completely black there was a purple stain which grew until two thirds of my display were purple, the lower part where it started was black.
then i managed to open this samsung hardware debugging menu where you can check for dead pixels by letting your display light up in red, green and blue. there i found out that only blue and green pixels very working correctly in the upper third. the next day every purple pixel was dead.
so 2 months after this little stain appeared my whole display was in the same state as your girlfriend's seem to be now.
so i don't think this plug (it sits in place pretty tight) got loose and that's why it doesn't work anymore.
and my sister had exactly your problem. she dropped her s2 and it immediately went black
she hat to sent it in as well ...
good luck
if you find out what's the problem and want to share it, i am curious about it as well
If possible, check for loose connectors first.
I don't know about replacing the screen. The sheer amount of LOCA makes it a messy job.
Probably the display is dead. You'd need to replace the screen+glass.
There is no back light on an oled screen.
