Horizontal lines on Samsung Plasma

I have a Samsung HP-R4252 plasma tv. About 1 year after I purchased it (right after the warranty expired) I got several black horizontal lines on the screen. A few months later the picture went completely out. Audo still works. Any suggestions?

    My tv has horizontal lines going thru half of my tv. I have tried switching the hdmi ports and cords and I still have the problem. I have a crystal clear picture on one side and the other half is watchable, but distracting. The lines are noticeable regardless of the lighting. I tried resetting the picture mode. I'm not sure what else to try.

Horizontal lines on Samsung Plasma


Hi,


The most common cause for the loss of picture is a bad Horizontal Output Transistor (HOT). but I would suggest you get a detailed estimate. I think that this would cost you about $60.

The horizontal lines means the vertical amplifier or deflection system has failed. There are over 100 components in this section and any one of them, or most of them can be at fault. However, the most common failure is the VOT or vertical output transistor (which is often buried inside a chip).

The repair will cost around $150 plus or minus.

FEW TROUBLESHOOTING STEPS YOU CAN TRY:

ONE: Do a hard reset (just to make sure there is nothing in the coding that is fowling things up). Unplug the power cord; leave it disconnected for 4 hours. That will restore everything to factory defaults when you power it back up.

TWO: Do the "whacking test" by banging your fist on a few strategic places to see if there are any cold solder joints or loose wires acting up inside the set.

If the above steps don't solve ur problem then I suggest you to go for a repair if you don't have any knowledge of repairing it.

Goodluck...

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.

It depends on color of line.

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.
