Sylvania 6842-PEM Flickering Problem

I have a Sylvania 6842-PEM that is about 1 year old. A few weeks ago I noticed flickering and blinking while watching a show, it stopped and restarted a few times. I contatcted the cable company and they say TV problem not their system. I tried changing cables and coverter boxes still the same problem. The problem is: after the unit is turned on the display starts flickering/blinking. You see thin white horizontal lines. they flicker and blink are a few seconds to a couple of minutes. Somedays nothing at all. Any suggestions

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.

Probably power supply failure. Power is getting to the TV (red light), tries to start (green light) then stops

Looking for info on Sylvania 6842 PEM


This RadioShack capacitor is no good - too low a voltage rating. Try replacing it with this one, or something with the same values:

This fix worked for me. Best of luck

Sudden Power Loss


Most likely a problem on the sub-power pcb. If its under a year old it is still on parts warranty.

Flicker-Blinking on picture


Too late now but I hope you had it serviced while it was still on parts warranty. With a couple of exceptions, service on those is by major pcb replacement.
