Zenith 50" plasma tv no sound

call 877-543-8325 this is an LG Executive call center and they will fix this for free. I have a 50" plasma I bought january 2006 which is out of warranty by 5 months. They faxed me and the LG repair shop a 30 day warranty for my tv to cover the repair. Just tell them you heard a pop and in my case the picture is distorted. All they need is the model number and serial number and they should take care of it. No arguing needed.

I had a similar problem with my 42 in Philips LCD HDTV.

Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.

Here are some options for you.

1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found at tv-part.com but supplies are limited. I would definitely shop around though.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.

Hope this helps and if it does please rate it accordingly. Good luck.

I just had a similar issue with my 46" Samsung LCD and fixed it myself for $5.11! I realize we have different tvs, but I bet it is the same issue ... crapped out capacitors.

I researched the problem online and most places, like samsung's site, referred me to call a repairman and called for the whole control panel or power supply to be replaced for anywhere between $400-$1000. I was like ... "screw that" ... I refuse to put in a fautly part in the place of a faulty part. So I continued to research.

That's when I stumbled on youtube. There are many how to videos on how to tackle this daunting task. I read that the issue was more than likely faulty capacitors and there is a very easy way to tell if it is in fact the capacitors that are blown. instead of having a flat top, faulty capacitors are crowned or even ruptured! When I opened up my TV I saw 3 blown capacitors!

So I bought 3 new capacitors all with the same uf and higher volts ... I think all three of my capacitors were 1000 uf and 25 volts. I kept the uf the same (recommended) and raised the voltage to 35 volts. It doesn't mean more volts, it just means it COULD handle more volts if it had to (which was the problem those cheap Samsung bastards screwed up on). This is a very common problem with Samsung TVs.

Anyway, I have never soldered before, but I did it. I warmed up the solder on the bad capacitors and removed them them slid thenew ones in and soldered them in and popped everything back together ... and PRESTO .... the damn thing works better than ever!

3 capacitors= $5.11
1 solder gun and solder= about $18
fixing an incredibly intimidating TV by yourself= PRICELESS!


Seriously ... don't be afraid to F up ... check it out on youtube and other place and save yourself a bundle. Source(s): I just fixed my TV!!!!!!!!
