No sound on some channels

It just means that where you are now doesn't have the Over the Air Channels at sufficient strength. Or perhaps you had other channels that came from a different source like cable, satellite, or some type of shared channels like you get in apartments?

Hi,
Sorry about problem in your tv for your favorite tv channels that your tv does not receive.
I hope your tv would be still under warranty so please return it to Store where it was purchased and ask for replacement. Take purchase receipt/ invoice along with tv.

Since June of last year all television broadcasting switched over to digital signals. Without a converter your radio will not receive any of the stations sound channels. Impossible to modify, only a converter will bring the stations in.

That's a broadcast signal issue not TV issue. If it was the TV all channels would be the same.

Try to see if you have 5volts for your EEPROM. If the voltage is normal try to replace your EEPROM or try to reprogram it. Your EEPROM is corrupted so that's why it will not store data.

TV is searching for over the air channels. Select in the main menu to go from over the air to cable channels and you should be fine.

Hi Suezie,

The problem is most likely your SAP being turned On.

SAP was created for audio programing including translations into a 2nd language. On nearly all sets, the SAP being ON will essentially select an alternate audio stream and will de-select or mute the main audio from the channel your are viewing. However not all TV stations have SAP enabled.

I am the Chief Engineer of a TV station in Denver, CO. We are not using SAP so if you selected SAP while watching my station you would get noise or static. There would not be any audio there.

Go to the front panel of your TV and select the "MENU" function. Step through the menus to Audio features and De-select SAP or Enable your main audio and this should take care of the problem. Alternatively you might be able to unplug your set for a period of time and it would reset itself. I used to get calls from elderly viewers when the set wouldn't pick up the UHF TV stations anymore. These were always after a power failure and the set had defualted to factory settings,

Different set manufacturers use different menu schemes and withou a password feature, these menus are so simple a small child playing with those fascinating buttons can change them for you to something you really don't want.

Good luck and write back if you can't find it. The set manufacturer and model number would help me look up a menu tree for your TV set.

Thak you,
Bernarr Howell
