    Sanyo DP42840

    I have this set lighting hit it. i have 2.01v on PS-on 0 on 5v, no other power.
    I have checked vasistor, replaced
    bridge rectifier is good but the voltage jumps around on the + pin the pin right beside it only has 62v next one only has 59v.
    The two main capacitors either have 62v or jumping. That's checking it on the hot ground.
    No 5v across the hot line except to the ps-on.
    When I try to trace the ps-on backwards voltage slowly dies before it gets to the optocoupler.

    Checked the components in the rfi filter circuit all is good.
    fuse good
    start up resistor good
    need help

        Do you get 240 AC volts on the 2 middle pins of the rectifier?
        What voltage on the main filter capacitor etc.
