I have no sound on my 4 yr old Panasonic Viera, 32" flat screen TV. The set was on and the sound simply disappeared - the picture is still perfect. Have tried all the usual switch off/ on, reset the volume controls in the TV set up but to no avail.

Can anyone help?

Model number?

Do you get any audio from the audio output to an external audio system (whether just computer speakers or headphones or the like)?

If you get no audio from the output connection, then you would need to replace the A board or main board. Or another option would be to just connect some speakers to your cable/satellite box (if you're using one).

Have a Panasonic Viera TC-L32C5 that came for NTSC only; need to change to PAL-N
