Trying to repair Sylvania 6842-PEM plasma T.V.

The problem is likely that several more capacitors are on their way out. Other possibilities are that you did not ascertain the reason for the failure of the cap; or that it took something else out when it went. If you don't have an ESR meter, your only option is to replace all of the caps in the vicinity and try it again (after checking everything else you can for faults).

Conversely, someone else on the group might have specific information which relates to your tv.

If a capacitor blows out, then it is probably having a higher voltage on it than it is rated for. You don't say what the voltage rating was for the original capacitor or what the voltage rating was for the replacement. Did you try to measure the voltage in the 10 seconds before the replacement blew??

No, I did not try that - Actually, someone from a different message board recommended this particular replacement capacitor (Radioshack item number

It sounds like your replacement cap has too low a voltage rating. .047 is much too small to replace an electrolytic capacitor. If you can find enough of the original cap to identify it, then you will at least know what you need. It's not uncommon for caps to fail from heat and old age, or a defect in the original cap.

The original capacitor was a small blue disc, about .5 centimeters in diameter, with the following writing on it:

Does this give you any idea about what kind of replacement to use? Thanks a lot

The 1KV marking is 1000 V. The suggested RS component was 50 V.

With twenty dollars, You can buy five hundred of them here for your experiments!! :-)

Note the description of the coding in the advert.

Thanks a lot!!

After my last post I did some research on capacitor coding and came up with the same numbers as you gave:

I ordered a few of these (at 18 cents each!!) and I will install them next week when they arrive. Hopefully, that will do the trick. I'll post back here and let all of you know if that fixed it..

Thanks to everyone who responded to this thread. You guys are all awesome!!

Throw the set in the trash and forget about T.V. all together. It's boring and full of commercials. I got so sick of T.V. after a short while I threw a bowling ball threw my t.v. screen and then finished it off with the bowling ball. I use the space that my T.V. was in and I filled it up with Twinkies and Oreos and orange cupcakes. I usually munch to pass the time.

F*ck what all'yall think. If I want to be heavy, that's my prerogative.

That new capacitor seems to have fixed it - it appears to be working OK. Thanks again for everyone's help. Cheers
