Galaxy tab 3, screen has power but is black.

Having an issue w/what I think is the latest kitkat update.

I put off the installation for like a week, finally decided to do it on Friday night.

Install went without a hitch, rebooted a couple times and finally rebooted and everything appeared to be working as it should.

Anyways, this morning I notice my battery is down to like 25% so I plug in (Original charger and cable)

Let it charge throughout the day and go to pick it up (Had plans that required my tablet be on a decent charge)

I unplug it and power on, I can hear the startup chime but my screen is black (not totally black, it still has that powered up glow)

I've tried every button combination/sequence I can think of, have disconnected/reconnected the battery, Still No Joy..

WTF, Kitkat update is the only thing thats changed on my tablet lately and now its blown away..Its never been dropped, is always in its case except for when I had to disco/reco the battery, not a scratch/dent/blemish on it.

IDEAS???

Update

Thanks for the input Joy, Glad it has helped someone as well as yourself out.

Referring to my first post you'll see "I've tried every button combination/sequence I can think of, have disconnected/reconnected the battery, Still No Joy.." No pun intended w/the "Still no Joy" part.

Anyways, tried powering the unit up again this morning (with power/vol +/- buttons annnd nothing, Same old same old.getting along great w/my EVGA Tab but I do miss my GT3.

i have the same problem with my Samsung tab and for one moment it looked like it was gonna start then back to black screen with the powered up glow. if anyone has any info, please comment here thank you

I have the same problem. The screen is black but it has a glow to it. Please help me

Same here.. I can be playing a game watching a movie or taking notes and then it goes black. so annoying.

I have a similar problem. The screen is as it should be when my Tab 4 is booting up but as soon as has booted up the screen looks as though someone took a scissor and cut the screen up into hundreds of thin horizontal strips and then tried to put it back together again. I reset the Tab to original factory settings but then it became even worse. Don't know if I have a virus (no protection - yes stupid) or I have dropped it and disturbed something internally.

Would like to avoid taking it to a shop and paying exorbitant fees.

Any suggestions.

Thanks

Barry

I had the same problem too (with the recent update and all), but I pressed the power button and volume button (both + and -), my tab restarted, and now it's working just fine.

Simply restarting the tablet doesn't always fix the issue.... I know that it certainly didn't work for me.... The black screen issue is on most cases due to the device being dropped (even if it didn't hit the deck very hard). In the process of doing so, what's happened is that it more than likely has slightly dislodged the LCD connector. What you will need to do is remove the back cover to your tablet (Make sure that the tablet is turned off before attempting to remove the cover in order to prevent any potential short circuiting in your motherboard or other electrical components). Once its open you will see 2 black tape looking connectors. 1 is for your LCD and the other is your battery charger. Both tapes should look fairly firm and tight. If they're not, then they are loose and more than likely the cause of your issues. You will see that at the connection point, there will (generally) be sticky tape or similar taped over the top. Gently remove each tape. Each connection point is only held in by a small black clip. Unclip each clip (easy to remove) then gently pull out and remove the connection. Leave each connection point unconnected for say 2 mins then carefully reinsert the connectors back into the connection points and secure it with the clip. At this point, what you want to do is to attempt to get each connector tape as tight as you can. the tape should late flat against the battery. you can do this by running your finger from the bottom of the tab and sliding towards the top towards the connection point. Then insert the connection point carefully and secure the clip. Get yourself some fresh sticky tape or electrical tape and stick it over each connection point. What I have found that seems to help is to also tape down each connection tape as well - just to help keep it secure. you don't have to go taping it down excessively, just 2 or 3 will do. I know that its the black screen issue we are attempting to fix, but the point of working on both tapes is that you may as well do it for the battery connector tape as well while you have it open. Hope this helps! :) Cheers!

Thank you soon much! I went on YouTube to find out how to take off the back cover, but I would not have even known what to look for if you hadn't put up this extended answer. Thank you, thank you, thank you! !!!

@tevo912 thank you so much. I was scared, but I did exactly what you said. This fixed the problem on TWO TABLETS and I feel like a certified smartypants. A million thanks!

tarafından

Thank you so much as well! I thought my tablet was a goner! You helped me fix it in 10 minutes!

tarafından

Wow I didn’t think it would work but sure nuff the lcd connection was loose and it was easy to remove tape and readjust. Thanks for this now my kid can kid YouTube lol ❤️ Taking off the back was a little hard but I can see why starting from the top left where the pin insert is worked better for me and it snaps back on easily. Again thank you!

tarafından

Thanks mate it really did work, the edges a bit darker but at least it’s visible thanks again 10/10

I have the same problem too on my daughters Samsung tablet 3. Looks like its going to load up then nothing happens, the screen is still lit up. I have tried everything... Tried rebooting it but still having the same problem. Really need some help as I don't want to be paying £70 to get it fixed when I know its something straight forward.

tarafından

Oh my goodness! This finally fixed my problem. They screen was still backlit, but nothing showed up and it wouldn't shut down or anything. I've been putting off taking it somewhere for over a week because I didn't want to spend the money. Thank you!!!

I restarted my tab 3 by pressing menu button + volume down button. Then the tab 3 restarted successfully. After that I uninstalled "Clean Master" and then the black screen problem solved in my case.

The GT3’s back is super easy to remove.

I initially used a guitar pick to open mine. After having done it so many times, I can now do it with just a fingernail.

Don’t be scared, it’s already F’d, what’s the WORST that could happen?

Alternatively a hammer and sharp chisel or just the hammer could solve all GT3 issues.

I had this same problem with my tablet. So all I did to solve the problem with my tablet, I pressed the home button , power button, and both of the volume buttons at the same time. Also, I had to hold it for about 1 min or until the logo appeared. And it turned on and function successfully! So if you have the same problem try out this method.
