    Hello,

    I'm having some trouble with a Sears model television with an RCA ctc146
    chassis.
    1. It currently has a black horizontal bar about 2 inches wide running
    across the top of the screen.
    2. When its first turned on (cold) it will cycle on/off for several
    minutes before staying on.

    Any ideas where I should start? Should I purchase a service manual? If
    so, what's a good site?

    Thanks,
    Bob M.

    Start by checking/replacing electrolytic capacitors in the power supply and
    vertical area.
