Question about Samsung HPT5054 50 in. HD-Ready Plasma Television

Open Question

Great ideas on how to fix my Samsung 50" plasma but they all seem to be for the techy geek (no offense intended). Will it be clear when I open the back of my TV which is the "Y" board? Where can I order the $200 part to fix it?

I had the same problem and had the TV serviced and found that the y board was blown $350 total. The repair guy explained that the board has a hot transister underneath that slowly leaked onto the board, but says that they can not get Samsung to admit to the problem. Works fine now but only have a 90 day warrenty on the parts.

SOURCE: error diffusion on Samsung 50" PLASMA TV

Yes the diffusion problem on your tv is due to the pdp panel aging. What you can try is readjusting the VSCAN voltage, there is a test point marked VSCAN using a DVM you can first check the voltage, should be around -- 190 turn the adjustment counter clockwise this should reduce the voltage, watcthing the picture turn control untill the sparkling pixels stop. That should do it. The panel is starting to age this may occur again until you can't adjust it out meaning a bad panel.

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 have the same problem. No video just audio.
No on screen display visible either (volume, channel labels) nothing.

Samsung tried to repair this under warranty TWICE within 2 months. Second time they replaced circuit board and it worked for another 8 months. So I paid $1.500 for a TV that died again after 1,5 year - this is ridiculous.

I have no idea what the reason might be and I wont try to fix this since samsung tech could not fix it without replacing circuit board.

This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.24001fc.jpg
