    When I change the channel either on the tv or the remote the picture does not change. The only way to get the picture to change to the channel the tv is on...i hit it. Its an older sony 40" tube tv and i know it would just be easier to get rid of it but for some reason i love that tv. PLEASE HELP Thank you

    I don't know what control the change of channels in a tv but I guess the problem is a relay which stacks or a bad connection inside.

    It's likely a bad connection somewhere in the control circuitry.

    This isn't something for a novice to attempt to repair.

    Sgt is right, don't attempt to repair it if you are novice in electronics. TVs develop very high voltages inside (20KV or more) which can be lethal. Better to take it to an expert.
