iPad won't charging/unlock iPad to use accessories

Try all the steps provided in this support article:--> If your iPad won't charge - Apple Support

If the issue persists, I suggest that you make an appointment (*) and have your device inspected at an Apple Store or AASP (Apple Authorized Service Provider) among this list:--> Apple – Location Selector. After checking it out, they'll give you all the available options.

(*) You can do it:

• Online:--> Genius Bar Reservation and Apple Support Options - Apple;
• Contacting a local Apple Store or AASP among the list provided above;
• Using the "Apple Store" app, available and downloadable from AppStore.

Sorry about that.

I would try to contact Apple Support directly (they have tools to run remote diagnostics), using this link:--> Get Support

We, just users like you, cannot diagnose that kind of issue remotely.

Giulio

My pleasure.

Best wishes for a speedy recovery to your iPad, but above all to you.
