If this set has a cable box, satellite box or even a receiver hooked up to it remove power from them and the set for a while and power back to see if a reboot cures this issue.

short of that someone who is willing and knows how to check things is going to have to look inside and test things, repair if not what I have suggested consists of replacing boards which can either fix the set or not and gets expensive.

SOURCE: samsung 50" plasma tv with no picture but has sound.

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!!!!!!!!

I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.

Reparing Samsung PS-50 C430 Plasma TV


Good day.
If you can identify those shorted transistors and you can remove them, you can actually order them from Samsung through this links http://electronicsmarket.com.au. It has everything Samsung, you will not be disappointed. Click on the link, click on Plasma TV's, then click on PS50C430, then (again) click on the version you may have and a list of possible parts will appear for this model. I didn't go through the long list (5 pages), but I believe what you're looking for is there. If not, you can contact them Website and ask not only for the transistors but you can actually get further help with your query.
Hope it helps. Cheers

Can i change the sound board for samsung plasma ps 50c91h in my home and what will be the cost of the board, the main problem is when we increase the sound above 17 point the sound goes off, please help me...


There is no sound board in your TV. You need to replace mainboard that control sound and video.
Before having replacing that board, try to use button to see if the same problem happens. If there is no problem with buttons, the cause from the remote control or sensor board. Main board costs $300 up, you can call Samsung and order or go to their affiliates.

Samsung Plasma 42" TV - 2006


Hi, this is quite a common problem for plasma screens and LCD screens. The fluroscent backlight is more than likely faulty and would need replacing. The best thing to do is to take it to a service centre because there are no user servicable parts inside the plasma.
