Question about Toshiba 32AV500U 32 in. LCD HDTV

1 Answer

Toshiba 32AV500U HDTV keeps losing channel 2.1

I'm trying to help out my elderly neighbors. Channel 2.1 (KCBS OTA - Los Angeles) keeps disappearing from the above TV. All other local channels have no problem. The only way to get it back again is to do a complete rescan, which then adds back in the multitude of Spanish and Asian channels which then need to be manually disabled. After the re-scan channel 2.1 has a strength of 97% and the picture looks great, but after a couple of hours the channel disappears again. It doesn't just get poor signal quality - it completely goes away, can't be manually tuned and once again it has to be completely rescanned. Rescanning and manually tuning out the unwanted channels is no easy task for an elderly couple and they usually end up calling me over to help. Their other two TV's have absolutely no problem with channel 2. They have a great antenna with pre-amp and proper cabling to all three TVs. I suspect a firmware issue because no other channels are having a problem and it is suspicious that only the first channel in the list is affected. Toshiba says there isn't a firmware update, however.

Has anybody else seen this issue or have a recommendation?

Elderly couples have had enough trouble with the HDTV transition, they usually can't (or don't want to) afford satellite or cable, and it's pretty aggravating they have to put up with issues like this!

SOURCE: some of my channels were lost after I TRIED RESCANNING I I LOST

Check your antenna direction (antennaweb.org or tvfool.com are good sources for signal direction). When I lose channels, it's a digital signal that came in with "bad signal" strength and my external antenna has rotated in the wind. (Oddly another TV in the house doesn't seem to lose the signal as easily even though they share an antenna.)

Also check the weather conditions and time of day. I've gained distant channels when scanning near sunrise or sunset and lost others during thunderstorms.

I hope this helps.

Sony bravia is stuck on one channel and won't change to any other station


Same thing happened to me when I was channel surfing and landed on channel 18.7 in los angeles.

What worked for me was turn the power off and then back on. While it is powering on press the channel button either up or down quickly. It should jump channels. It only jumped one channel for me and was still frozen. Repeat the process and I was able to jump more channels out of the trouble zone and back to normal.

Once my tv was working again. I tried to autoprogram my channels again but it still picked up 18.7.

Also tried to "hide" the channel in channel management but it would go to 18.7 and froze up my tv again :(

Hope this helps anyone that has the same problem.

Look in your manual for a channel scan entry. It should be an item in your setup menu. What this does is re-scan for all the signals it can receive.
Once the scan is done, it should display all the channels that are viewable in your area

Tv guide/tuner problems


Most likely the TV Guide is broadcast from the OTA PBS channel. I don't know why its being lost. I'm thinking its probably a firmware problem of some sort. Adding the PBS channel back in, making sure the signal comes in ok and leaving the TV off for a while might help.
