SOURCE: 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.

SOURCE: My 50'' Samsung Plasma has dead screen after only 2 years

Hi,
welcome to fixya!
without doing voltage checks, my best guess is this:

Plasma hpr5053 or hps5053 models will burn out a buffer board or both, there are two buffers and the Y board.
I usually change all 3 at once, but if on a budget you can try to remove one buffer and see if you get half picture (upper or lower)
this is something only a technician should attempt. the boards cost $200 each (buffers)
$300-$400 (Y board).
if you actually get half a picture the Y and one buffer are good, a bad buffer usually burns out the Y board. and in really bad cases the panel is bad also (not common, but possible)
For part#s , specific help you can post a model# , but again this is a repairmans job not something the average customer can fix.
hope this helps
Eric

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!!!!!!!!

Prima Cineplus 50" Plasma PH-50R18C will not turn on

The ambient temperature might be high. Check whether the foolinf fans are working or not. If not, check out the reason for it. The TV must be placed at least 6cm away from wall, and should have sufficant ventilaation.

The TV turns on and shows a picture that you can watch and within 10 minutes the TV loses its picture, however, the light is still green. If you turn the TV off you can get the picture to come back after...

The issue here could be a capacitor within the power circuit. Also could be a power transistor that is faulty. On the easy part it could be a matter of reprogramming the unit but I doubt it.

T.V. Loses its picture when it gets hot but I can still hear it

Hitachi sets are prone to Power Supply Faults.

I think your PSU is getting too hot, then shutting down.

The better sets have Fans in them.

Either repalce the Power Suplly or put up with the fan.

It will however still fail in the end, one or more components are allready failing under stress / load.

Thanks

Samsung HP-R5052 Plasma TV

It related with Power Board(50%) or Y-Main(50%).
But, if you use the power bar with surge protacton, need to check
the power bar's lamp when the TV is turning on & off.
