Hello, Edward.

 

The set is a Toshiba Model 35A44 that we have owned for about 3 years or so.

 

We will be sitting watching TV and all of a sudden the volume indicator pops on and goes to zero, as if someone were adjust it using the remote control. The set is on a cable system, and we already went to them and got a new remote, thinking that might be it. We reprogrammed the remote, but it still does the same thing. We were thinking someone in the neighborhood must have a Toshiba and we are getting a signal. But our closest neighbor is at least 100' away, so that doesn't seem likely.

This is a common problem that can have a variety of causes. As strange as it may sound this problem can be caused by light dimmers, florescent lights, a bright light shinning into the remote sensor on the TV. Other causes are a high powered transmitter close to your location, such as a ham radio operator or a CBer. It is not likely being caused from a remote in a neighbors house. Covering the remote sensor's access on the front of the TV will eliminate the problem being caused by another remote. Once all of these sources have been eliminated I believe the problem will be a bad control board in the TV. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. If you have no electronic training I will suggest that this be professional replaced. The repair should cost $150 to $250.

Edward, can you tell me precisely where the remote sensor is on the front of the TV? It is not readily apparent to me.
Expert:  Edward replied 5 years ago.
They can be rather hard to detect. It will be on the bottom plastic panel. A flashlight might help locate a small discolored area about the size of a pea. Cover the entire panel with a piece of cardboard if you are not sure of the location.
