My plasma tv samsung sps4243 has lines blurry over picture

The symptoms you are describing with your Samsung plasma TV are consistent with a failure of the plasma display panel or a failure of the plasma drivers that control the display Here are a few things you can try to troubleshoot the issue:

1. Check the connections: Make sure all the cables and connections to the TV are secure and not damaged. Loose or damaged cables can cause visual distortions on the screen.
2. Perform a factory reset: Sometimes a factory reset can fix issues with the TV. Refer to the TV manual for instructions on how to perform a factory reset.
3. Check the internal components: If you have experience working with electronics, you can try opening the TV and checking for any obvious damage or loose components. However, be aware that opening a TV can be dangerous and may void the warranty.

Snow usually is due to poor TV signal strength.

your av board possibly may have crapped out

try to check your cables connecting your tv one of those lines might be broken. hope it might help you.

Change the voltage regulator 5m0380r

unfortunately these newer tvs do not display the standard definition analog channels very well. the picture gets better when viewing digital channels but doesnt display at its best untill u place it on a high definition channel

There are at least two issues here. First you have bad buffer boards. Second Very possibly a bad X-Main bd and P-Logic bds. Have a trained Samsung tech troubleshoot the set.

covergence problems and its not adjustable you need work done on the convergence board or a new board and realignment which can be timely.

I think you have a fault on the line output stage either dry solder joints or a fault with components on the line output stage or a faulty line output transformer. If you can check this for yourself otherwise find a competant technician. Hope this helps.

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.
