I have samsung 50 " plasma tv. it is connected to direct tv hd receiver. i turned it on and there is sound but no picture. we can change channels also with sound and still no picture using the remote.
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.

SAMSUNG 50'' PLASMA MODEL NO. PN50B450B1D-This TV has been sitting for awhile, bought it new, after a year it started turning on and off over and over, it would click every few seconds and the screen doesnt come on probably cause it shuts off 5 seconds after it turns on, never had a problem the first year but after 12-14 months this problem started and its been sitting ever since, im wondering if anyone is having the same problem, as soon as it turns on you hear the click and see the little red light turn on then click it shuts back off, over and over until you unplug it...help! i really liked the picture quality, i bought a new 55'' vizio but the older plasma looks better to me, let me know if i need a switch or fuses or??? thank you
