So, I have a Samsung SM-T230NU. When I tried to power it on, it flashed for a split second the Samsung Galaxy Tab 4 logo and then went blank. I figured it was out of juice, so I plugged it in and let it charge for an hour or so.
When I came back, it was flashing and going dark.
I tried a different cable. As soon as power was applied, it flashed and went dark again.
Now, the boot logo is showing for an even briefer amount of time.
I am suspecting the battery or USB port. I don't have parts readily available to swap, however.
It may be worth adding, when I plug in the device, without touching any buttons, the screen starts flashing the Samsung Galaxy Tab 4 boot logo. I would guess a stuck power button, but the power button travels freely. When I unplug the tablet from the computer, the flashing stops.
Trying to boot it with power + volume up garners no response from the device.
Any ideas?
Having same issue here
Tried hard reset, no dice.
Tried opening the back to see if I can identify some loose connection, didn't see anything funny. I am not an electrician.
My sister's having the same issue with her T230NU. It still boots (it'll boot to the Samsung splash, but then it flashes off the screen in half a second; this repeats every 7 seconds), but only if it's plugged directly to the wall charger. She let it sit overnight to charge, and it's still got this issue. I'm pretty sure her battery was drained when the issue started occurring last night, but it doesn't look like the battery has charged much (if at all) since then.

Noticed my E900 was unexpectedly powered off. Tried to switch on and got the LG logo for 3-4 seconds, then... nothing. Seems to power off. Failed to boot?
Subsequently, power button did nothnig. After removing/replacing battery and powering on, I get the same LG logo for a few seconds, then nothing.
The LG logo tells me it isn't a dead screen. Connected to PC/Zune and nothing seen.
Are there any button combinations to do a reset?
I have ordered a new battery, but I think that's unlikely to help.
Any thoughts?
Thanks.

I had already tried charging the phone of course, and had left it plugged in for several hours. No change, still as dead as ever.
But later I connected to a PC. No sign of life from there, but I happened to leave it connected. An hour or so later I noticed it was displaying the almost-full-screen picture of a battery, with a small fraction of green at the bottom.
So it seems the battery had been totally drained to the point it was (almost) unrecoverable. Perhaps it was the low-current trickle from USB that got it going again.
Back up and running now. Glad I didn't panic and buy a new phone!
Hi there,
so I have here a Galaxy S4 Value Edition Black (I9515) and it is doing simply nothing. Just black screen, no lights, no vibration, battery is charged in another phone to be sure! I tried all the normal button combinations for Recovery or Download mode but nothing happens. Not even a charging indicator when plugged in.
Story:
I had it on my desk over night with the battery pulled out and in the morning I was able to get to the boot logo with the blue recovery text. But it will just hang there. After one or two tries it will only display half the bootlogo before it goes back to doing nothing again.
So I waited another few hours with the battery out and tried using a USB JIG to get into Download mode. This surprisingly worked on the second try and the phone stayed for around 20 minutes in this mode and was also identified by ODIN. While searching and downloading the correct stock pda I disconnected the phone und reconnected it every minute to check if its still working. After around 20 minutes it was still recognized by windows but not anymore by ODIN. So I now have to wait another few hours to get back into Download mode.
Questions:
-What could trigger such an "only power on when discharged"-behaviour? Fuses, Capacitors? idk
- Is there a way to quickly discharge every component on the board, so that i dont have to wait that long.
- What Hardware components should I inspect closer? Measunring points? Voltages? (multimeter at hand)
Thanks in advance!
Good day XDA,
My phone went on a real havoc starting yesterday when it kept on rebooting in the "Samsung Galaxy S5 powered by Android" logo. It doesn't go past it without having the phone plugged into into a power source, either USB, powerbank or wall charger. After charging it 'til it goes full, it only takes few minutes to few hours before it goes to the same cycle again - and I have to plug it in again in order to use it properly.
What could be the problem? Your immediate response is greatly appreciated. Thanks everyone!
hi , i find when i experience this issue is when play store updates theme that i have in use at time , soon as i reboot i get bootloops ...i fix mine by pressing and holding vol down menu and power for as long as it takes for bootloader then press them same keys again but release before bootloader so that your phone boots as normal hope this helps
I know this is the combination for force reboot but sadly, that doesn't help. Thanks for the idea, though.
Tried clearing caches from recovery?
Battery still good?
I think the battery might be the problem. When I tried charging it, I went back and it was on 92% then few seconds later, it jumped to 100%. I tried booting it but with no luck, so I pulled the battery and upon putting it back, it dropped to 50%. I pulled and put it back again and it went to 84%. I'm thinking it might be the battery. I cannot boot into system or TWRP, only on Odin mode but I need to save the files saved on my internal storage as it has photos I haven't backed up yet.
Long-time lurker, first time posting on this forum. I have a SM-G928A S6 Edge+ that is only a week or so old that ran down and will not boot again. No signs of life at all, and no amount or combination of buttons will get it to display anything. If I disconnect the battery (I repair cell phones professionally), and plug the device in, I get the normal charging screen, and the phone will even boot correctly and run for about 30 seconds before rebooting. I replaced the battery with a new one, and it does the same thing. With either battery connected, no button combo, charging, anything will get the display to turn on. Nothing displays - completely black. There is no accessing recovery, no logo, no safe mode; staring at a black screen. If I disconnect the battery, it operates almost completely normally. Bone stock phone. Any ideas anyone?
Thanks!
So Sunday night, my phone as at 34% charge, I went to plug it in with the same Samsung charger I've always used and I noticed a moment later it started to re-boot itself. Found it odd but then it was stuck at the white "T-Mobile" screen for some time, and I removed the battery to re-boot and this time stayed at the Samsung screen. Following troubleshooting tips, I removed the battery and held the power button down for 30 seconds, replaced the battery and tried to power on and now it won't do anything. No boot, no load, no power. Unable to even use recovery mode. I tried 3 usb chargers all with no sign of life on the device.
Thought perhaps the battery was shot, went to two t-mobile stores who were no help, eventually went to a battery/phone repair store and tried a new battery, still nothing. The person said it could be a board issue or software problem (but they did not test it other than putting a battery in.)
Is this thing bricked now? Or are there any options I may have to repair/recover anything on it.
Never rooted or anything, stock S5 with the push updates from t-mobile and such.
