Sylvania 6842-PEM 42 in

Hi Zexxal - I see that several people are having trouble with a blown capacitor in this particular TV - I have the same problem. I replaced the blown capacitor with a replacement from RadioShack (the one from the link you posted), and the TV worked fine for about 10 seconds, then the part blew out. This happened twice. I was wondering if you had any idea about what could be causing to fail; perhaps you know of another part that needs to be replaced also? Any advice would be great - thanks a lot.

    The part from RadioShack is no good - wrong voltage rating. Try this part:

    It worked for me - TV runs great now. Good luck!

If you are certain that the capacitor is OK, there could be a different problem on the main power board or even on the sub-power board. The sub-power board should have output voltages even if the main power board is defective.

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

You can find a replacement Capacitor at any local Radio Shack. Just ask them for a 50 Watt Capacitor and they will give you a box of 2 for like $1.45

0.047µF 50V Hi-Q Ceramic Disc Capacitor Pk/2

If the above link does not work, add this to your browser:

You will see the blown capacitor once you open up the back of the unit. It is over to the top left side of the unit.

Here is a link for some basic soldering instructions for circut boards.

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.

Sylvania 6842PEM


Have fixed a bunch of those as a Sylvania ASC. There is a small ceramic capacitor on the main power PCB that has ruptured. It must be replaced with a different part, a special type of capacitor, or it will just fail again. Sylvania had recommended replacing the main power PCB rather than repair because sometimes there was additional damage on the board, however replacing the capacitor fixed every one that came to us. I preferred that because some electrical voltages have to be adjusted if the circuit board is replaced with a different one.
