Question about Toshiba CZ36T31 36" TV
Picture and sound comes and goes. Can sometimes hit sides and picture will come on. Have remove back and cleaned electronics (all on a black plastic tray 7x12" bottom of set). Seemed to help but soon got to where if picture goes out/on hitting does not work now, hardly. Can I buy the whole tray of guts since Im not able to fix much?
sounds like a cold solder joint in the tuner circuitry. Unless you can do it yourself it's probably not going to be worth the repair bill.

I think you flyback transformer is going out. Eventually it won't come back when you hit it.

Testimonial: "Thank you but what is the solution?"
that silver box is called TV tuner (see picture ) ............ but in your case that is not the problem ......... after 4 or 5 yrs (depending on usuage ) in some TVs on mainboard & CRT tube's circuit board at some soldering joints cracks develops ... then due to loose contact TV behaves as you have described ........ when you are hitting that lightly on its side then these cracks at soldering joints are getting connected temporarly & for few seconds or minutes you are getting normal picture ....... so solution is most of the soldering joints on mainboard & on CRT circuit board has to be resoldered ....... only good tv service engineer can do this without shorting joints or damaging components..... so that silver box ( TV tuner ) is not the problem because when it gets deffective then you will get picture that comes when tv is switched on ---- usually it will be blue screen ......& also if you connect dvd you will get picture normally ...only thing is that you won't get picture from cable or antenna ..............
