Capacitor for the Sylvania 6842-PEM 42


No, it will not work (I tried it - twice!). Here is a link to the replacement part I used, and this fixed the problem - TV works great now.

Pulsing/strobing on black screens or dark backgrounds


It is very likely that there are electrolytic capacitors going high in ESR on the processor and driver boards, and also in the power supply areas. The tech should be able to see this by monitoring supply distributions with a scope.

Depending on the complexity of changing the caps on the boards (if it is actualy a cap problem), the best choice may be board replacements.

In almost all the cases where I had this type of fault, it was a number of capacitors that had to be replaced.

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

Parts


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

Link to Item

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.

Hope this helps out. Good Luck. Let me know if you need any additional assistance.

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.
