Trials and Tribulations of TV Repair

Nice to hear there are still some businesses out there which care for their reputation, glad to hear you got it fixed!
John, I was reading your thread about TV problems and noticed the part about artifacts that can only be seen on your LCD and not your CRTs. Have you read my post in the thread "AV vs S-Video" on this site?

You may actually get a better picture using your RF input or your composite input. It is definitely worth trying. It's to do with the comb filter (Y/C seperator) in your set-top box vs the one in your LCD TV.
Tooth, some guys over at satteliteguys recommended the same thing. I'll have to give it a try.
