Hi- I have had a Samsung HP-R4272 42" plasma for about 3 years now, so it's way out of warranty. A few months ago, it bagan to flicker for the first few minutes it was on, and here and there there would be a few pixels that would misbehave (light up bright with one color), but again, only for a few minutes, and never in the same spots. Two days ago it started to show a really bad image, with these bands here and there under the whole image, and this mess of red distortion all over the screen. I have seen what i thought were other colors in the distortion, but really it almost all red - like spray or bleed. Changing inputs doesn't seem to make a diff. I can see disturbance through the black when there is no feed. I generally use the RBG component, but the vid input on the side gives the same effect. I am attaching a pic or two I tried to take. I am hoping this is some video board of some sort that failed. Anyone have any ideas or pointers? I would be eternally grateful.
I have a very similar problem. My HP-4272 is about 3.5 years old. Started off with the bottom half going black for a couple of seconds. Then the top would flicker. Now I get the following picture... Not sure if I need to replace boards (Y-buffer lower, upper, and/or Y Main Board)? or if something just needs to be "adjusted"...
Pals, I have almost the same problem but mine is in the middle of the screen and is thinner than that. Whats the cause of it??? can it be repair and isnt too expensive??(mine is a samsung PL-42P5H, 2 years with ps3 hooked)

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.
It's possible that the motherboard or the controller board for the screen is defective. At this point, I would use the warranty from Vizio. It should be no doubt that it covered. Here's the info you will need from the Vizio web site. http://www.vizio.com/support.aspx?id=1588
sounds like a faulty scanning head to me......
when images are scanned they are normally imaged in 3 colours red blue and green these are then combined to give a full colour scan. sounds like you are only getting the blue pass.
not alot that can be done here, if it is in warranty (check with manufacturer for duration of warranty as sometimes this can be more than a year) they should repair or replace this for you
Sorry to hear that. You could fix it with Best Buy or the warranty service repairman recommended by Panasonic.com I have a client that had used one of the panasonic repairman to fix the same problem that you have about a year ago,the TV is good ever seen. I am in the A/V installation business, my recommendation(Pioneer Kuro Plasma TV or Sharp LCD.)Very good track records from my clients. solutiondoct
Look in your owners manual and contact Samsung and complain about the Repairs. They can't do anything about the promotion deal, but they should check into the repair issue for you. Especially if the Company servicing the TV is an Authorised Samsung Center.
I have a Samsung 50" plasma, that has been blacking out over the last 6 months. A 9/2005 set. Now its practically unwatchable as it happens 3 times in an hour. Its not heat related - I have a high volume 9" fan activated on TV power on. Turning the set offf/on usually makes it come back for a now short while. Considering to go put it in the back of my pickup and park it in front of Best Buy and discourage Samsung purchases. This is the 2nd Samsung TV I've purchased (the other a 32" tube) I gave to my folks a couple years ago and its gone bad as well. Samsung product may look good, but their video engineers are not.
Did you get this problem resoslved? I had the same issue a few months ago. I tech came by and took my TV to the shop, a few days later he said it was fixed as they needed to make some adjustments.....The TV has been fine up until a week or so ago and now the red dots have appeared again. Was wondering what happened to yours.
