Got a 7 year old Toshiba TP50F90 50" rear projection TV with average 6-7 hours per day use that's started distorting sound on most channels when set to stereo. It sounds OK when set to mono. And the sound is OK playing pre-recorded DVSs or VHS tapes. So my layman's guess is the problem is in the TV's tuner's stereo circuitry. Cable company came out and checked the cable and it's OK.
Describing these symptoms to local (Atlanta) TV repair guys brings "blind" estimates in the $500 range to fix.
Anything I can tackle myself? Worth fixing? Time for a new TV?
