Actually very faint sound at max vol w earphone but effectively silent.

It can't be the speakers because it does the same with two

AM I right to think it is a capacitor in the amp circuit? The reason I
doubt is it does not respond to hitting/shaking. THe other thing is the
faint sound at high volume doesn't match past experience with amp
capacitor burnout.

THe unit is a Supersonic 7" 193a HDTV with a 12v power adaptor.

PS, is there any "electronics repair rules of thumb" cheat sheet
anywhere?

Getting you to the proper documentation would depend on your current
understanding of electronics.
