i tried to post pics but i am a noob and it wont let me. sorry

nevermind about not getting pictures. here they are.

Try reseating the display cable.

i had taken it all apart and back together again, and its still the same.

Did you try the old display? If the old one works, and this one doesn't, then this one is faulty.

it is the old display. it worked perfectly up until i replaced the glass and digitizer. even while my screen was cracked, i could use and see the phone just fine.

How did you get the glued down digitizer off? Did you start prying?
Oh, and you should have gotten an LCD/Digitizer combo.

i got it off by heating the edges carefully with a blowdryer and used the plastic guitar pick tool to remove the glass/digitizer from the lcd. it came off way smooth and easy.
i was thinking to myself i should have got the combo as well, but didn't have the extra 100$ now i totally regret not getting it. FACE PALM!!!

I looked again. You (somehow) broke the LCD. Look in the second photo at the top in the middle. See the dark spot?

If there is no physical damage, send it into HTC. You still might be under warranty.

That doesn't mean there is any visible physical damage. If he carefully replaced any void stickers, he should be fine.

that dark spot it just a piece of tape that is holding the generic screen protector on.
there is no more void sticker, and i purchased it from someone quite a while ago, not through a mobile service.

the g2 screen is very fragile the way it was designed has the digitizer wires running around entire screen but the flex cable is in the top right around where the front camera is a single crack will break touch on almost entire screen mainly up to the area where it happened; you should look into a replacement or warranty if you decide to do it yourself make sure to buy lcd+digitizer, I know that replacing only digitizer is cheaper but it's an almost impossible difficult task, I have lots of experience in taking apart electronics and decided to try and replace only digitizer with my g2 in December which ended up in lcd breaking half way through screen dissasembly

LCD screen white after replacing digitizer.

Hi,
I've replaced the digitizer and battery on my LG G2 D802. This was done after the original digitizer was cracked from a fall. Before the repair the screen and phone worked perfectly and half the digitizer was functional.
The battery was breached while attempting to disassemble the phone, so this was replaced as well.
When booting back up after the repair, the LCD is now having issues (no issues prior to digitizer replacement). The screen goes all white on boot up, and seems to be grey in it's turned off state, as opposed to the normal black colour. The phone seems to function besides the screen, and the digitizer seems work.
What do you think is wrong and how can I fix it? See pictures below.
Possible malfunctions according to myself are:
- I've read that white screens can happen when new hardware is not recognized. Maybe a factory reset will fix it?
- The connectors for the LCD screen not being tight (they seem fine to me);
- The screen got messed up from the heat or melting glue when heating the screen to peel off cracked digitizer.
I would very much appreciate your help on this issue, so thanks!
Pic 1: Screen is turned on and an all white screen is shown. Pic2: Screen is grey in its off state (looks like a 90s Nokia or a calculator). The bubble in the middle is caused by residue glue. Pic 3: G2 grey screen compared to normal black LCD off state of an iPad.

look like lcd was damage during removal of digitizer

When phone is powered off is that LCD still grey? If yes then probably its been damaged. Is there any colour problem it is definitely damaged. Also you stated that you replaced the digitizer and battery. AFAIK G2's LCD and digitizer are fused together so when you replace it will come as a unit. Maybe it was cheap clone?

He tried to do just digitizer which is a no no unless you have the correct tools. He said "- The screen got messed up from the heat or melting glue when heating the screen to peel off cracked digitizer."

Yeah now i see. That explain greyed screen. Lol. Bad choice. A set of it would be cheap and less hassle to operate. Not to mention he will got both LCD and digitizer as a new unit.

Yep, bummer!

I would recommend getting one with the LCD and Digitizer in the housing. Super easy to replace.

I didn't say that. I said it is a possible reason as to why the screen is now grey. Except for the colour it doesn't seem heat damaged. There are a bunch of videos on Youtube doing this same repair, so it's definitely not impossible. For all I know the screen might be greyed out if it's not connected to the battery. That's why I'm asking here.
Could anyone point me to a reliable supplier where I can get the LCD and digitizer as a unit without paying a fortune? I live in Europe btw.

same problem, how did you get it fixed ?

Dead screen on Galaxy S4

I bought it about 9 months ago on Craigslist. I'll never do *that* again.
After I got it home, I noticed that the screen looks as if it has been replaced. A tiny bit of glue in the upper corner. Oh well. It was working fine. Or so I thought.
A few weeks ago, I started getting these strange vertical lines through the entire display. I couldn't figure out any pattern to it (time of day, temperature, etc.) It would usually go away within a few minutes.
Then today, I hit the power button to bring it out of "sleep" mode, and the screen flickered a few times... and died. I tried to power it back on; no dice. I pulled the battery and tried powering it on; no luck.
I plugged it into an AC charger and at least I saw the battery icon. I powered it on, and the screen flickered and died again.
Is this a known error or a simple fix? Do you need more information?

Sounds like a dead display, not a real common problem but it happens. You can replace the display which is not a huge deal but my concern is the glue you mention. That may make it a bit of a challenge to repair. Depending on what type, how much and where glue was put.

How much would a new display cost if I replaced it myself? How do I know it's just the display, not the digitizer or something else, etc.?

Check Ebay. Ebay is usually loaded with replacement screens/lcds. If you do buy from there make sure it is a Sprint variant of the SG4. There are suttle differences on the inside between GS4s. The lcd is the part you'll need to replace if necessary. I would advise, taking the display off first to inspect what the previous owner had done. It's entirely possible that the lcd cable ribbon is loose or not seated properly to the board.

The display will be the outer glass, digitizer and LCD all in one package. You can try to replace parts separately, but trust me it is not worth it. The outer glass is glued down to the digitizer, that is a real pita to get apart clean without damaging what is left. Then if you do manage to get it apart it may not function as well or be as durable as originally because the outer glass no longer makes contact with the whole digitizer. Think of it like a single piece of wood vs a laminate like plywood.
Granted it may not be the display (there is always a possibility it could be something else -like aliens) but most likely it will be the display. I would think of it this way- try to replace the display, if that does not work you can resell the display you just bought and you might be out $20- well worth it in my opinion.

Thanks for the info. Looks like the glass/digitizer/LCD will run me about $100, so I'm not sure it's worth it.
Does anyone have the link handy for the Galaxy S4 drivers so that I can get what I need off the phone?

I've followed instructions to take the motherboard out and put it back in. Is it difficult to ge the display off? Is the LCD cable ribbon easy to find?

[Q] Screen troubles

So here it goes. I've had nothing but issues with screens on the G2. My first G2 had the glass separating from the frame during the first few weeks that I had it, then it decided to go into a boot loop randomly and Sprint replaced it.
My second G2 initially was fine but then of course the glass started separating after a few months from the frame and I just ignored it. About 8 months later I dropped and and cracked the digitizer, luckily I had synced my bluetooth keyboard/mouse to it and was able to back everything up.
I then ordered a LCD/Digitizer/Frame assembly. I installed it and noticed the frame and the glass were separating and I could see the back light like my other screens, this one also had some white spots and looked like pressure damage. The seller tells me that they accidentally sent me a defective screen (a "return") so they send me another one, which I notice has the glass already separating from the frame, at this point I don't really care anymore and just deal with the one I have already and leave the "new" one on the shelf.
About 6 months later a portion of the screen stops responding and sometimes will go crazy clicking and swiping everything. So I decide to order some 3M 3mm tape to properly adhere the glass to the frame of the "new" one I have on the shelf. I followed a guide and it all seemed to go smoothly, I let it dry for a week to make sure it won't start separating like the others. I tried installing it and while it looks great, the phone runs super slow, and touches respond after about 20 seconds. I unplugged the digitizer connections and it still runs super slow with my bluetooth keyboard/mouse. I plugged back in the connections and went into recovery and noticed it was just clicking everything and going crazy. I also noticed I couldn't power the screen off, I had to hold the power button down until the phone shut off.
I ended up putting my old screen back in and it works fine, other than the small portion of the screen that is unresponsive.
Any ideas? I feel just ordering a brand new phone, but I'm pretty sure it'll just have the same issue after a few months ..

What are you doing with it so that the glass separates from the frame? do you use a cover? could you post some pictures?

Nothing crazy. I use it and am typically pretty careful. I had my Epic 4g for 3 years and never had any issues with it.
First one did not have a case, I have had a case for the second one and it took longer to develop the issue.
It seems to be a pretty common issue due to the bezel being so small.
