Strange TV problem

[soccerdad]

OK, I know this is a PVR forum but I thought I would toss this one out. My ~8 year old 32" Toshiba TV suddenly has lost sound on channels 9-12. This is not an issue using the MVP, but it is a problem for non-PVR viewing. It works fine on all my other TVs so I know it is not the cable company. Last night it worked for a while on channel 9 and then the screen went blank for about 1 second and when it came back, the sound was out of sync. Today it is fine on channel 9, but I am still dead (I get video only) on 10-12. I can understand loss on all audio, but can't understand just 3 channels. Also the sync issue is very odd. Any guesses? (My thought is a conspiricy by the TV/cable companies to send out some magic bullet to kill my TV right before the Superbowl so I will pop for HD! ) Go Panthers!

I figured it out (thanks to Google). SAP somehow got turned on and it killed the sound on some channels since the cable company does not actually transmit a second stream of sound on that channel.

Just out of curiousity (sp?)... what is SAP?

I think it stands for Separate Audio Progamming, well not sure. It is a second audio stream broadcast with the original programming. It allows shows to be dubbed into another language. Here in the US it is typically Spanish.

Ok, we have the same thing here. Didn't know what it was called, though. However, knowing the TV standards in Europe/America I wouldn't be surprised at all if it's two completely different technologies that are used ;-)
