Make sure your SAP button is not turned on. This will give you a no audio condition when watching broadcasts thru the tuner. If this doesn't help then your tuner could be defective.

Hey Wilt: We had the same problem, for the same model of Toshiba TV. Had it repaired yesterday. Turns out the problem was the power supply (P.C.B). The total cost was $192.66 Canadian funds (taxes and labour all in). Our model was 6 years old, buts its playing like a brand new unit now. Hope this helped ...... Good luck

hi there, check some cold solder at the board or some loose connection inside the unit. ty

It sounds like a defective tuner or a IF module as well. It may also be a defective capacitor(s) or cold solder joints inside the tuner circuitry. I woud suggest to use a VCR or a TV convertor connected to an Audio/video input to change channels instead of fixing it.
Good Luck.

One of the power supply areas are most likely going intermittent. This can be from cold solder connections on the circuit boards, or from some components failing due to age.
An experienced tech should be able to service your set, but it will be expensive for the time involved. Sometimes these types of faults can be very time consuming to resolve.
