Your TV is a plasma, it has no backlight or inverter board, First confirm your picture source or video cable is not the problem, Try another input, if it is OK, then check the TV. You must check Vs and Va voltages or Y Sus board when you loose video. Do this only if you are comfortable around electricity, You can hurt yourself or render good parts useless.

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Surf the site with patience. Pull up older posts.

Only one bad door switch should do that

The 20 min time out is the GEM or Body Module,
which is normal only because you have a bad switch,
otherwise it goes to sleep when either front door opens

Put radio on & open a door,the radio should go off
& kill the time delay if no issues exist

Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.
