Question about Samsung HP-R4252 42 in. Plasma HDTV

Purple and white distorted fuzzy lines running up and down and side to side on tv

I have a Samsung HP-R4252 plasma 42in. It worked great for 6 months, with an occasional wierd "Glitch" as I like to call it here and there. The top half of the TV would blink, then turn into a sorta blurry/fuzzy rainbow colored assortment of lines that went side to side, with no visible picture behind them. A solid mass of colors and fuzz. This happened on and off for the next 6 months, and like a dummy I didn't have it serviced. Now that the warranty has expired, it finally blew up. The lines have moved from the top half of the tv, to the lower left corner, and it is constant. The lines run up and down, and side to side, moving with the picture displayed in the section of the screen. Multi-colored and mostly purple, fuzzy and VERY annoying. They are not solid anymore, but almost like a plad pattern you would find on fabric. I have tried everything Samsung told me, besides getting it serviced. I am not affraid to take it apart, as I am a certified computer repair technician and certified Automotive mechanic. By this I mean I know what not to touch. (Capacitors, Transformers, blah blah) If anyone has any suggestions, please let me know. Thanks!

I just had my lower Y-buffer board swapped out to fix a problem similar to yours. After an hour and a half of on-time, the lower half of the screen would flicker on and off with the same appearance you mentioned. Changing out this particular board fixed it for me. However, since it has gone from top to bottom on your set, it may be more of a main board problem for you (that controls both upper and lower halves). Beyond this, I don't know any more. I am considering getting a service manual to gain more knowledge about the various PCBs in the unit so I can fix any future problems myself.

You may have to change the DMD (Digital Micromirror Device). Also you may have to change the color wheel and lamp; the DMD will cost you around $200-$300. The color wheel and lamp will together cost you another $300.
This type of tv repair may be very expensive especially if you have to pay a technician to perform the repair for you.
It's at that point that you may decide to invest in a new unit.

Samsung Plasma TV - picture has 6 sections of horizontal lines

All I can say is when you watch T.V. the plasmas run off of plasma gas and when you leave something on for so long it burns in the screen. I have the same T.V. and when watching like the weather channel it leaves lines but they go away. If yours are permanent then you can't do anything, but it may help if you go on your remote and go to "menu" then look for "setup" and scroll down with the arrows on your remote. Look for "screen burn protection" and select "white screen". This will make your whole screen white and it may take out the lines. If you let it sit white it won't hurt it. All one color won't hurt, the only thing that hurts is like bright white lines in front of a dark background. Just give your T.V. a break from time to time ESPECIALLY ON VIDEO GAMES. T.V. shows that are HD usually have their channel icons that move or are very dim and they won't hurt. Just go to what I told you and let it sit about 20 minutes, if that doesn't help, then the T.V. you have i believe comes with a 2-year standard warranty and if it's under warranty take it back if you have the reciept. If no reciept then call 1-800-SAMSUNG.

Vertical lines across my entire screen

My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

Samsung HP-R4252, white vertical line

Unfortunately you probably have a bad lcd panel. This is caused by the heat of the panel releasing the solder that holds the ribbon cable that supplies the picture information to the panel. A lcd panel is more often than not, more expensive than getting a new tv, also the new tv will come with a warranty. Most of the unit I have had this problem with were uneconomical to repair. Sorry for the bad news, Hope this helps.

Verticle lines on screen

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
