My MiL has a 42" Toshiba HDTV which my wife & I gave her. After a storm, which may or may not have anything to do with this, she lost sound much of the time on 2 of her cable channels. Both happen to be local OTA channels. Just cuts in and out. Video is poor on those two channels. All other channels are just fine. TV is plugged into a high quality surge protector.

An older analog TV on the same line receives the channels perfectly. A call to the cableco yielded nothing of value.

As they are 5 hours away, I haven't seen it for myself, there may be other problems. I told her to call Toshiba.

Any ideas?

Sounds like a set problem. I'd call Toshiba (hope it's still under warranty). If you put another set on the same line and video&audio work fine it's not going to be a cable problem. Tell her what I would tell my mother-in-law, don't watch those channels....LOL!!

Thanks. I just hope she can work it out between her & Toshiba without bringing me back in. Long drive.

I wonder. The locals tend to be on higher frequencies on cable systems. The storm may have damaged the splitter that goes to that set so that it is acting as a low pass filter. A weak signal could have audio muting occur while still having just enough signal to prevent video mute.

Try replacing the splitter (and the coax from the splitter, just to be safe) before writing off the TV.

My feeling is that if it was the TV, more channels would be affected.

Shouldn't make a difference. If you put in another tv set in place of that one with the same spliter and the set is clear and sounds good it's the set. If a cable tech comes out and puts thier test set in-line and all is good on thier set it should be good on your set. Now you just got banged for a Service Charge as well.

Oops. Missed the "On the same line" piece.

Still could be the issue if the smaller TV has a more sensitive tuner. You haven't ruled it out completely.

Older TV might be using a cable box. Didn't think to ask.

That's a whole diffent story. LOL!! If they have a small 13-15 inch kitchen set, tell them to plug it in where the LCD is. If they have the same problem then It's either the coax or splitter like mentioned eariler. If not then it's the set. Also bypass the box. Just plug the coax into the set.

If all the other channels are fine, the same as before, I doubt if it is the TV. Even though its on the same line as another properly functioning TV the line has to be split. That spliter is where I'd start.
