Tablet doesn't charge when on but charges when off but is in a loop

Just yesterday my tablet started to not charge at all when it was on, i tried different cords, adapters, all that, then i turned it off and saw that it can charge however its stuck on an infinite loop, first charging for a few seconds, then going off, and then on again, and repeat, getting no charge at all.

(Fyi i can still turn it on, and the piece where the usb cord goes in is getting extremely loose, meaning its coming out of its port.)

If you have any possible solution, please comment ASAP.

Hi,

What is the make and model number of the tablet?

It sounds as if the USB charge port is loose on the systemboard.

Most USB ports in laptops, tablets, mobile phones etc. (not all) are a SMD (surface mounted device) type connector mounted directly onto the systemboard.

You will need to have the requisite SMD soldering skills and tools to repair / replace the port.

This is not a job for novices to try. You can cause more problems than what you had if you don't know what you are doing.

I recommend that you contact a reputable, professional mobile phone repair service and ask for a quote to repair / replace the port.
