My Westinghouse 36 inch TV has picture and sound when I turn it on but when I change channels, the picture disappears and I have only sound. The picture comes back if you turn the TV off and back on but...


Hello, it sounds like your inverter board is goin out on the set, when you change channels if you notice on almost any TV the screen goes dark and the new channel appears, it sounds like you are not getting enough power out of the inverter board to power up the backlight enough to come on. This is why the sound remains because everything else works fine and the sound is connected to the main board.

No sound on one channel


Just one channel has no sound?

Then you need to change the sound option stereo or mono instead SAP.

Hi,

There's a set-up menu in your ps-3, you have to change the menu from analog to digital output.

Picture problem when changing channels


Are you using a cable box or a satelitte reciever? If so i would suspect them first. If not, unplug the TV for 2 minutes and try again.
