My Samsung Galaxy 4 tablet wont charge. I plugged it in and the battery sign appears but it wont start charging. It either freezes on the battery sign or the sign appears and disappears. The tablet is off. Wont turn on. When I try to turn it on, it turns off quickly and the battery sign appears.

Have you tried a different cable or try moving the connection around carefully to see if the charging port is broken you can also try a reset. Power button and volume down button at the same time till it says its resetting

Firstly, the battery is not holding a sufficient charge to boot because the LCD screen is constantly turning on. This causes a tremendous drain on the battery for a split second, if your battery is completely dis-charged like mine then you will never get ample charge into the battery for it to turn on hence why the screen keeps failing.

  1. Open the back cover.
  2. You will see 3x vertical ribbon cables. Carefully remove the on on the right, it is marked LCD (Convenient)
  3. Plug your charger in and leave it to charge for at least 8 hours. (Use the wall socket adapter, it produced more current than a USB port on your computer) Now that the battery is not being drained constantly by the display the battery will have a chance to get some juice into it.
  4. After you have left it to charge for some time unplug your charger (Crucial) , re-insert the ribbon cable for the LCD you removed making sure that it is in all the way so that the lines on the ribbon and the board are aligned.
  5. Power on. If it boots great. If not it may be time to purchase and replace the battery ($25 on eBay) and make sure that your charger has enough power to keep it charged and at 100% while in use. Beware of leaving any Li-Ion battery fully discharged for a long period Good luck!

Anyone tried the volume down + power button hold down trick for 5-10 seconds?

I had the same issue. This might sound weird but this is how I solved it. I tried all the different button combinations didn’t work. While trying the combinations I realised the tablet felt cold. Kept the tablet against my body while charging for about half a hour while watching a movie on laptop. Body heat seemed to have warmed it enough to start charging. Suppose you could try other warming methods.

Right now it sounds like you are having battery issues. what is the voltage/amperage of the phone charger you are using? If you do not have that written on the charger, what model is the charger?

The last time I used the tablet was about 4 years ago. Needless to say, the battery was completely drained. I plugged it into a charging cable connected to an iPhone 2.1A charger but the display just kept on flashing. Hmm. I then connected it to a wall charger with the same result. I was 100% convinced it had to do with the power supply not being strong enough. The 2.1A output may not be true 2.1A. I then switched to a portable battery charger with 5V 2.1A output and voila, the Samsung Tablet is now charging as it should. The display stopped flashing, and it shows a battery with a small green line at the bottom indicating it is charging.

The Battery connector might be loose, open the back cover and Solder it to make sure it is connected properly… If the problem still persist then change the battery… It should work… Good Luck…

I had the same problems. Wouldn’t charge, screen kept turning itself off. I pulled the back off and disconnected the battery and could see that 3 of the 6 copper teeth on the motherboard (that the battery connector plugs into) had come off the motherboard and stuck themselves to the connector. No way to remove them without destroying them so I stacked two pieces of cutup old credit on top of the battery connector and snapped the cover back on. It’s pretty tight in there already, so the additional pressure was enough to keep the connector pressed hard into the motherboard and the power connection complete. No more problems. Won’t last forever, but it’ll do the trick until I can sort something else out.

My Samsung tab e wouldn’t charge was going take back off and unplug charging port but before I did I simply turned off tablet plugged in charger and it charged in no time

My phone is an LG K40, everytime that i put it in charge it the the battery keeps flickering on and off idk what to do my phone aint getting charge now imma be bored at heck plz help me idk if it’s my charger or my phone plz help me!!

Try cleaning the charger port with a paperclip- pick out any dust bunnies in there, and if needed carefully scrape the metal connectors. That worked for me.

I stripped off the insulation from my charger down to bare wire and hooked up jumper cables attached to my Lexus and cranked it. The phone popped but it still won’t come on. The Lexus is ok. It starts now, but not the phone. I think the phone is broken. Will check the warranty, but the phone is getting old. Probably from about 2000. But, I did purchase a lifetime warranty when I bought it from Cingular.

Warming works! I placed it under my leg whole in bed for 20 minutes!

I have a Samsung Tab a10.1 and after not using it for a while and putting it to charge, the lightning/charging symbol came up but after a few seconds the screen started to flicker a lot. I tried two cables. Both connected to the USB front of my PC. Turns out it worked when I used the normal power plug and into the power outlet.

I tried the thing were you unplug the screen and that worked… when it died it had the same problem, I tried 8 hours first (it worked the first time) and the second time I tried 5 hours (worked after it died) and now it’s staying on! Hope this helps!
