Question about Samsung 50 in. Plasma TV
Well, it could be something inside, but it could also be a setting.
In SETUP, there's the option of using the internal speakers or external speakers. If it's set on external speakers and you don't have any connected, then you get no sound.

My Samsung 52" plasma TV will shut off while watching TV. It will do it repeatedly and we have to turn it back on. Is it overheating and shuts down? How can this be fixed?

SOURCE: blackout problems
It could be the LVDS cable that is connected between the logic main board and the main board, sometimes this cable is too short and comes loose from one of the boards, it could also be a sign that the logic main is going out or the panel itself is shorting out

It's a pretty common problem. The no picture but sound problem is usually the y sustain board. I've replaced 2 on mine now. The 680uf 35V capacitors usually are bulging because one of the power transistors went and took them out. This has happened to both of the y boards I had. One time the failing y board took out the buffer boards too, and once it did not. The fix is super simple and anyone with even the most rudimentary knowledge of computers or electronics can do the labor yourself. You should do the simple stuff first by just doing a quick test with a multimeter. Just check the power coming to the y board. After that you can just remove the y board by removing 3 cables and like 3 screws. Plug in the new board and it's done! You can source the parts from a place like shopjimmy or discount merchant. 3 boards were like 200 bucks. 1 board is like 100 bucks. Labor took me 15min. Think about that the next time an electronics repair place charges you 1000 dollars. Of course they check everything (Yeah right) and warranty their work (I don't) but if you check the service manual it states that this is the most common repair. Look for the Canadian manual online. Hope this helps!
