Tablet doesn't turns on or charge. Overheating at the right sup corner

I literally just barely had this issue with my iPhone about an hour ago, so I went to this website and found the answer- there is something to do with the battery that once it dies and your device gets hot, the battery needs to be reheated- some people recommended applying a blow dryer, some said put it between 2 cable boxes that emit heat, and one said take off any kind of case you have, plug it into the charger( I actually don't even know if that's necessary, but it's what I did) and rub the battery area between your hands for about a minute or until you get some kind of response- good luck!

I have the same issue with my tab S. I got it checked from a local tech and he confirmed that Power IC is heating up and needs to be replaced. As Samsung is just selling the tabs and not giving repair services in Pakistan. I got brand new ICs from Ali Express. On replacing the IC, my device didn’t turn on. Now the techy is saying that its processor is shorted which I am not agreeing.

Before turning on, device has nothing to process. Why it is heating up on charging in ‘off state’, still a mystery. But I am not giving up and will update if some luck comes in the way.

This is a common issue with most tablets and usually it starts affecting it the older it gets as the MotherBoard could break down or short circuit some parts. A short term fix that I've found is to cool the tablet by placing It on an ice pack or putting it in the fridge for a minute or 2. This could help to turn it on but is again only short term. But keeping the device cooled and turned off when charging to help limit heat to the motherboard will save the life in the long run.

I have a Samsung Galaxy tab A SM-355Y. About 4 months prior it started to get hot when charging and using. Then one day whilst charging it got VERY hot and never turned on again.

Today l received a brand new battery for it, l then put it in (very difficult to open case), but following a YouTube video l managed to replace the old one.

About 1.5 hours into charging it up, l felt the back of the unit, and, as you’ve probably guessed, hot in the lower third section. So, it wasn’t the battery at fault!. So then l let it cool down, and then switched it on again (to try and isolate exactly where the heat was radiating from). The location turned out to be -, if you can imagine dividing the back into six sections - one line down the centre (top to bottom), and two equal lines side to side - now if you measured 2cm up from where the USB cord goes in and drew a line around a small soup spoon (between the two lowest sections of the case), that is where the heat emanates from. Now, having given that location, l have to tell you about a very strange abnormality, right bang smack in the centre of that ‘spoon’ shape, is something l that can only think of to describe as a ‘pimple like’ bump, (raised from the inside of machine, the bump being proud on the outside of the case) - l can give an exact location, - 4 cm up from USB port, in the dead centre. Possibly, what ever is causing the problem is behind that, and the raised ‘pimple’ has been caused by the heat of a faulty component directly behind there!

Can anybody shed some light on this, particularly what is directly behind the ‘soup spoon’ and the ‘pimple’ areas?
