sound bar and subwoofer used to play fine,then quit playing after a couple mnutes and shuts down--why

Aug 9, 2018
tv Panasonic,vizio sound bar used to work fine. Then sound bar will only work for couple minutes then shuts down. Will start working after short time, but only for couple minutes. There was no schematics with system bought from Sams Club.
I would guess that the amp inside the soundbar is overheating which would shut if off. When it cools down it will come on again.
If you get inside it you may be able to spot some discolored parts or blown caps but finding out the values if your can't read them off the part is going to be really tough if possible at all
