Question about RCA F27440 27" TV
My tv is a 46" Sony. It is probably 6 years old. Recently the picture only comes on for a minute then the screen goes black. The sound works perfectly any ideas?
I'm assuming this is a projection set given the size. Sony TV's have circuits to monitor picture tube operation and cut off video when something isn't within limits. It's very likely your set has one or more bad tubes (there are 3, for red, green and blue), troubles on the circuit boards connecting to them, or problems with the set's control circuits. This set should be serviced by a professional if you want to keep it.
