    RCA RLCDV3282A-B LCD power off and on every few minutes

    I have a LCD combo tv model RCA RLCDV3282A-B, and it broke down. The symptoms were

    [1] very low volume

    [2] flickerring image proportional to sound and brightness

    [3] the power turns off and on every few minutes

    So I took it apart and looked at the power board. I found some swollen capacitors. So I replaced all electrolytic capacitors (14 of them) according to their original specs.

    Unfortunately it did not fixed all problems. I have a the volume and no more flickering (good image). However, the power turns off and on every few minutes randomly.

    What I am missing? What are my next steps?

    might be a solder joint problem, recheck your work and check all other solder joints.

            Can't see your connector pin out. Need to check your voltages on connector to mainboard.
