Sylvania 6842-PEM 42 in. EDTV-Ready Plasma Television - Page 2 - Answered Questions & Fixed issues

So it comes on and then shuts off? how long does it stay on?

Is it always in the same place? Most likely one of the driver boards is defective.

The defective capacitor, if that is the problem, is not obvious. But the main power board has a standby mode and an operating mode. Many of the outputs are off in the standby mode. Do the output voltages go on when you press the power button? The tv draws considerable current when the power turns on, about 7 amps, and less then 1/2 amp when off. Do you have a way to monitor the current?
If the capacitor is the problem, it needs to be replaced with one with a Y5P dielectric or it will overheat and burn out again in a short time. Of the main power boards that I had in for repair, about one out of three had a problem other than the burned capacitor.

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.

Good luck!!

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

Sounds like a blown capacitor. I fixed the same problem in mine by replacing it with this one:

If you can do a little bit of soldering, you can fix it yourself. Good luck!

Here's a good replacement for that burnt out capacitor:

Good luck!

You need to replace the burnt out capacitor - the little blue disk on the upper left side of the power circuit board. Here's a link to a replacement that works:

Just solder the new one in and it should work fine. Mine works great with this replacement. Good luck

This fixed the problem for me - the TV works fine now. Good luck.

This will help a few people out there. This is the Service Manual for this TV

send me an email and I will tell you the code. I am in seattle and have some extra remotes.

Hi,

Unfortunatly, the Plasma Panel was never available as a replacement part.

A shipment of new boards is now available. You can purchase one from the distributor Vance Baldwin.
if the capacitor didnt fix it, it must have more problems, and those other parts were not available.

Check the menus to make sure the audio is not turned off. If that is OK and you have the means, try using other inputs. If it works on some inputs and not on others, that would imply a system control problem, which is unusual for that model.

You probably just need a new main power board. You can buy them from Vance Baldwin, Probably $125 to $150 with S&H. Adjusments are needed with a digital voltmeter while the board is operating in the set. Some techs have told me that the capacitor failure sometimes damaged one of the switching regulator ICs and that those parts were not available. Before we worked out that a special type of capacitor was needed, the capacitors we installed were getting very hot and we knew that they were not going to last long.

yes, you can get a 50 watt capacitor from Radio Shack and put it in yourself. It cost me $ 1.45 for a package of 2. Just ask them for a 50 watt capacitor

Just be careful when you remove the board, it holds a charge for a little while. I know from experience 8-)

Just take a small soldering pencil and remove the old one, then add the new one. You can get everything you need from Radio Shack for under $20 bucks. (if you have nothing to work with (solder, iron, capacitors Etc)

One hint, be careful with removing and adding the new one, don't burn or scrap the board and make sure when you add the new one not to put to much solder on the connections. Before you put the board back in, verify that you did not leave any solder on the board or cross the connections with the solder.

Believe me, this unit is very easy to work on and you should not have any issues.

Good luck. Hope this works for you.

Let me know if you need any additional information.

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

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.
