Question about Samsung LN-T4661F 46 in. LCD HDTV

Open Question

Horriblydistorted display until TV warms up. Then clear.

Samsung replaced TV in '08 for the same problem in addition to the green vertical lines going up and down the screen. Warranty ran out 3/09 and TV started the distortion in May. TV turns on with a very distorted picture, improper shading (all black or discolored on part of the screen) or sometimes goes to all black (like AV1 mode) but you can still hear the sound. Additionally, there are four large horizontal separations across the entire screen that further distort the picture. Once the TV warms up, however, everything clears up and works fine. Very bizarre especially since Samsung replaced the TV last year and the same problem is occuring. Please help. Any recalls?

SOURCE: 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.

SOURCE: samsung 42" Plasma -Black vertical line when turned on.

It sounds like an Intergrated Circuit (IC) has fried. Even on a good day, this is not something you can attack at home. As a tech (and as an owner of that model samsung), I'd need a map & tools to know what's going on. Your best bet in this situation is to contact Samsung and let them recommend an authorized service center in your area. Sorry I can't be of more help, but this is a rather serious problem.

SOURCE: tv is about 4 years old. Suddenly developed two

Your plasma screen is made up of 1080 verticle lines and now a few of these lines are not working. This is the screen itself and needs replacing.

One green vertical line in 42" samsung plasma tv mfd. last 2008


A thin line, like a pencil line, all the way from the top to the bottom is most commonly associated with the display itself.
In your case a 42 inch panel. These are no longer available from most manufacturers, and even if it were it would be cost prohibitive
Something like: Core Price 250.00 Part Price 1200.00
Total Price 1450.00
.plus about 150.00 shipping because it is considered oversized

Vertical lines


Was this problem why you changed the panel in the first place?
check your connectors and perhaps you have a bad Tcon.

LCD display problem


Are you sure the cable is properly seated? You will typically get a tint of red green or blue when a particular pin on the cable isn't making contact. The lines on the other hand would indicate a bad display. Best advice would be to check the cable and if its all the way in hen replace the monitor. They are not worth repairing and also dangerous to work on.

My CRT TV displays a single horizontal white line across the screen. It will flicker and try to display the picture. If you smack it you'll get a quick picture then back to a line. After about 10-15...


The single line means that the vertical deflection doesn't work. And since it is working when you kick the tv or has warmed it's clearly a bad connection - open the case and reseat the wires going to the tube coil.

im afraid to say that your display has gone the best thing you can do is call the supplyer of the tv if its under warranty or call samsung. the cost of a new display will be 400 - 500 pounds so you may have to buy a new set.
