Question about Toshiba CF27H50 TV
We used the set earlier today for about an hour then turned it for for couple of hours. When I turned it on it came on as usual then after about 10 seconds, the screen went blank. No sound, no display, no nothing. The set is still on, you can see the fuzzy's. If you turn it off and back on it does nothing. If you let it sit abit, cooling off?, it comes on but will go off again after about 10 seconds. I hate to spend a lot on a 10 year old TV but hate to give up on it if it is something simple. Any ideas?
It soulds as of your solder joints are getting old and starting to crack. If the screen goes completely black then I would resolder all the major solder joints on the main PC board, and if you mean that the screen goes to all snow (as if the cable went out) then I would also pull the tuner and resolder the joints inside it too. If you do not have experience soldering on small PC boards then allow a qualified tech to handle it for you. The fact that it works sometimes means that all major components are fine and the repair shouldnt cost too much.
