Answer 1

Some really old Trinitron and Trinitron Plus TV's use a different type of remote all together. They use a "Supersonic" remote that you probably can't buy anymore.

If you're changing channels on the channel selector on the TV and not having any luck, open the channel selector by pulling on the little handle, remove the bracket on the left, and there should be directions on how to change channel settings. Basically, you turn the outer dial to change bands (red=low VHF, yellow= high VHF, blue= UHF), and the inner knob to change which frequency (channel) in that band you want.
