SM-G530T1 backlight only after replacing LCD with SM-G5308W_LCD by "inhouse"
I have a SM-G530T1, unlocked and the digitizer and LCD had broken. I replaced them and all seemed fine, but then the digitizer died on me and in the midst of removing it, the new LCD cracked. I replaced it, and had issues with the new one, seemed like the connector was loose, and I had to constantly reseat it. So I replaced it again, and when I powered it on, the backlight would flash on then off, and that was all, it stayed black. I replaced it 3 more times with the SAME ISSUE. I was positive my display connector was bad, though it looked perfect, and I posted a hail-mary on Reddit and had someone say they had the SAME issue, until they got an OEM lcd.
The LCD I got, well all of them, were from Amazon, and were about $25 for the LCD & Digitizer together. The model is SM-G5308W_LCD _FPCB_REV0.6 and the brand printed on it says "2014.09_17 inhouse" All of the displays are like that. So does anyone have any experience with these?

After I replaced the crashed screen glass and digitizer on my sisters HD2 it doesn't work properly. The phone starts only if it's connected to a power source and when it starts the screen backlight is turned on but no picture appears.
I've replaced the screen glass once before on my HTC TytnII and then everything went fine but now something got wrong. Does someone know what it might be?
I've tried to disassemble it and assemble it again but it's no difference.
Get the LCD and digitizer together and then assemble with the HD2.
Looks like the 2 are not correctly stuck together and this is a cumbersome process requiring the use of an oven.
So the two must stick together to display any picture? It sounds strange to me but I've used some glue that I bought on the same place I bought the digitizer so it should be ok.
Check the LCD clip on the main board, as well as the flex cable. If both are fine, your LCD is dead and needs to be replaced. The digitizer does not need to be taped or glued onto the LCD for it to work. When reattaching the LCD, be EXTRA careful of the clip, thats the first part any of my techs damage when they first work on this phone.

Hi all,
I sucessfully changed my cracked digitizer on my Nexus 7 gen 1. Followed the procedure in youtube and heated my screens and used guitar wire to remove the cracked digitizer-looked good.. Cleaned up the glue on the LCD and and taped the LCD to the digitizer. I did not glue the LCD to the digitizer. Reasembled everything and booted.
I booted and everything booted correctly. Except for starting. I had to drag the lock icon over to the right to open the tablet. Swiping did not work.
The digitizer does not work with swipes. I had to touch several times to even get a response. I could touch a icon app to start it but could not turn pages if I needed to. I thought the digitizer electronics was defective, so I bought a used motherboard(suposely 100% tested).
When the new motherboard came, I rassembled everything.
I powered up the new motherboard. Half of the screen had sigguily lines and I could see the boot up icons coming up on the other half. Thinking I did something wrong, I pulled the battery connector. Rechecked all of the connections, and pushed the start button. Nothing happened. No light of any kind.
I reinstalled my original motherboard and same thing, no boot up at all. The only difference is that with my original motherboard, I heard a "bonk" sound from the speaker 3 seconds after I push the start button, but nothing on the screen.
Any suggestions from anybody? Maybe bad LCD connector. If the connector is bad, would that prevent booting?
Anybody seen this before?
Help!!!!!!

Leave it charging for half hour and press power button for 10 to 15 seconds and it will boot
Hi all,
I think I found the answer already.
My LCD flat cable is broken. Using a ohmmeter, I found most of the flat gold traces have a break in them. Probably from my dis-assembly of the
and assembly of the LCD too many times. i am ordering two LCD cables from a China distributor.
I hope it fixes the problem, I have not received the cables yet.
But the question remains. Does having a bad LCD cable prevent or stop the Nexus 7 from booting?

Touch screen unresponsive -> Inserted new LCD+digitizer -> touch screen unresponsive
My friend's Galaxy S4 i9505 had a crack in the glass and he asked me if I could fix it, so I carefully separated the glass from the LCD and glued a new glass on it using Loca UV glue. At first glance the result was absolutely great, but when I powerd on the phone again, the touchscreen suddenly was unresponsive. After re-checking al connections over again and resetting the phone back to factory defaults, the touchscreen was still unresponsive.
We decided to order a new LCD + digitizer unit from a Chinese Ebay seller with 99% positive feedback. After about a week and a half it arrived and I moved over parts on to the new screen and installed it very carefully. After checking all connectios and booting up the phone I unfortunatly noted that the touchscreen was still not functioning.
Now I really don't know what to do anymore, since the new LCD's touchscreen (digitizer) can actually be a D.O.A. what I would find bad coincedence or there is some sort of problem with the phone's mainboard wich would be bad luck.
What do you guys think? I am really not sure now. I will probably contact the seller of the LCD and try if I can return it and he will send me a new unit (No money back guarantee :crying: )
Maybe there are some other options left? Any ideas, please?
EDIT: Problem solved. Repairguy discovered that a small chip on the mainbord was damaged. He replaced the chip and now the phone works like a charm.
I had a similar problem after replacing my entire front assembly housing (preassembled glass, digitizer, LCD, frame). After I got everything transferred over from the old one (vibration motor, front camera, earpiece, headphone, motherboard, antenna micro-coax cable, lower bezel control ribbon), hooked everything up, screwed rear housing back on, reinserted SIM card & SD card, reattached back battery cover, powered it back on-- then to my horror, there was ZERO touch input response on the touchscreen. Panicking for a few minutes, started planning on moving everything back to an old Android (S3) phone, then thought to try a reset first-- I pressed the up volume & power buttons, got into recovery mode, then selected "wipe cache partition", then selected "reboot". After it restarted (and holding my breath), VOILA it worked! Touch input was restored, Hallelujah!
Just commenting here so I remember where this thread is.....lol
I'm going to be replacing the screen on my son's S4 when he's saved up enough money to buy the replacement screen......
Does anybody know if (in general) ebay purchased screens are reliable?......

I have a T-Mobile HD2. A few months ago, the digitizer got a little crack but touch was working fine, so I order a new digitizer and replaced it. No matter what I did, the touch wouldn't work with the new digitizer (I know about front buttons putting pressure on digitizer ribbon cable which sometimes results in touch not working).
I thought problem might be the LCD connection slot for digitizer, so I order a new LCD too. But even with new LCD and new digitizer still touch doesn't respond! What am I doing wrong?
This problem is still baffling me. Right now, I have 2 sets of digitizers and LCDs (old ones and new ones I purchased) and no matter what combination of them I use, digitizer is not responding.
I have to say the old digitizer used to work fine before I opened up this phone, it was just it had a little chip/crack in the edge so I wanted to replace it just to make it nicer. But now digitizer won't work at all!
Is there supposed to be an insulating layer between digitizer and LCD? What wrong did I do by opening up this phone? I was very careful. The only thing I am not putting back for now is the front keys and its flex cable. Other than that, all what I took apart before, I have put back!
Hey friends,
I recently replaced my cracked screen but half the screen is static/noise. The touch works on the entire screen though. I purchased two screen replacements off of eBay and both have the sameness problem so I'm assuming it's the board or something as I also factory reset the phone to stock. Any help?
Definitely a connectivity issue, maybe a bad cable connector or something broken on the motherboard since the LCD panel has the cable pre-attached. Check the LCD interface cable that connected to the mainboard for damage and check the connection making sure the locking tab is in place.
Yea that's what I thought. It looks fine though and the LCD interface cable is fine and the locking tab is in place.

I replaced my screen when it did that half static thing with one off of eBay. It lasted a few months working perfectly and today it crapped out again. I ordered a new screen hoping it will fix it again, but will be watching for a new phone deal.
I am not sure if the screens go bad or something else, but replacing the screen worked for me the first time. Odd that both of your replacements are bad. Did you check that the ribbon cable is seated perfectly, there is a line on the cable and one on the board to help you line them up right. I put mine in crooked once and it gave me the half static screen you describe.
I do think the screens of eBay are not top quality. My replacement had all sorts of bright areas that my original screen never had. I have replaced my screen 3 times now due to breakage and other issues.

I thought the replacement screwed this up for me but I have hotspots too on the replacement screen. Not a huge deal but really weird. So definitely be prepared for the hot bright spots for sure if you order screens off ebay
