Hello, when I use the TV/VCR button on my remote the TV cycles through channels 3, 4, AUX, and S-VHS. The TV doesn't even have an S-VIDEO jack. I have been able to get into the service mode but I don't know what to change to get rid of the S-VHS channel. I have 25" Magnavox model TP2526C. How do I get rid of the S-VHS channel?
