Question about RCA R52WM24 52" HDTV Projection Television
I turn the power on but youll hear a low thonk sond then itll tur itself of without showingn a picture
Most times when you hear this kind of sound on a TV it is because the flyback transformer is bad (from what I can remember anyway!). Its been a while since I repaired TV's, so hopefully someone can verify my info. The flyback transformer steps up the voltage very high which powers the color tubes. If that is bad, you will get the thunk sound. Also, if memory serves me well, there is a high power output chip that could be bad as well. Please, anyone who knows TV's, please verify for me. It has been years for me!
