The condition of your TV called power supply overcurrent shutdown. The TV is going into a protection mode to prevent further circuit damage. That's why it will not turn on or not powering up. I would concentrate on the power supply section board. Bad regulation of the incoming voltage could caused this issue although,there is a capacitor across the incoming line and nuetral.Maybe its leak or dry up and cause the problems,change it out with one of identical rating .I would probably also check the flyback circuit and flyback transformer although now you are getting into dangerous area,especially if you have no electronic experience background. It could be also be a loose ,crack or cold solder joint,a blown fuse,fusible links or other component .It could be one of several boards.Unfortunately the level of sophistication on these TV make it virtually impossible to diagnose them further without taking them apart and probing around with a multimeter and other tools.This TV is handy enough to take to a repair shop find a good one.You will probably have to pay $75 to $100....

Hope this may help you..

Wont turn on


Take the back off of the TV and look at the power supply board (middle of the set). One or more electrolitic capacitors will have the tops swelled up. Replace them with the same value parts and you will be OK.

Sylvania 6842-PEM Flickering Problem


Something is breaking down. Possibly a specific ceramic capacitor on the main power pcb that has been troublesome. Usually there is just a loud pop and the screen goes dead. If the set is less than a year old it is still on parts warranty and the technician could just change circuit boards until the problem is gone.
