Unplug for 30 seconds from it's power source and then try it again. If that doesn't work, call Samsung for further troubleshooting and have your model number and serial number handy. Please be prepared to tell them how long the line is.

Try to replace the YSCAN board. If not fix it, then it's the PDP Panel failure.

SOURCE: When I turned the tv on only vertical lines appeared

I talked to a Samsung support helpline and it needs to be taken to a service center for repair.

SOURCE: Samsung LN-S4692D - Vertical lines (>15) & static on screen

this sounds like a scan board gone ,, if you check ebay youll see two things,
1, other tvs for sale with the same fault (It might give you a clue to the fault ie , which board )
2, the same tv as yours with a broken screen ,

i dont know how good you are with taking things to bits but i personally would buy the tv with the broken screen and start swapping over the internal boards ?

Have you checked your home insurance policy for broken tv,s
it may have fell of its stand when you were'nt looking?

Tip

TV shows either: black screen with: white vertical or, horizontal line


If Your screen shows a: white vertical line on a black screen or, a white horizontal line on a black screen:
Your TV vertical or, horizontal power transistor or, chip is getting too hot.
A vertical line indicates the horizontal circuit is at fault, a horizontal line indicates the vertical circuit is at fault.
To troubleshoot: Turn on your TV untill the line shows then: after about a minute, remove power (unplug) the TV, remove the TV back cover, find the too hot transistor or, chip; using component coolant; spray the too hot component with the component cooler until the screen comes back to normal. To fix: apply white coolant cream to the back of the too hot transistor or, chip. or, if there is room, a small fan can be wired in to cool the part. Radioshack sells the cream and, also a "component cooler spray" that should find and, fix this problem, also; with power removed you can, if you feel it is safe; carefully (with only one hand) feel the part; it will be very hot! (it could burn your finger!) Do not touch anything else! (this will not hurt the tv; when the picture comes back on (the offending part has cooled) you have found the problem part.

Flashing black and white vertical lines


Vertical lines in the display indicate a failing screen. New screens are expensive and not worth the labor and parts charges to repair it. It's new monitor time.

Black Vertical Lines in screen


All I can tell you is that you maybe have left your T.V. on a channel that didn't move for so long, or maybe someone else did and it burnt the screen. Plasma's run off of plasma gas to create the great picture and they collect on the screen and stick. What you need to do is go to your menu and look for "screen burn protection" and put it on white and let it sit for 20 minutes. All of one color such as white doesn't harm your T.V. The only way anything burns is like a bright white line in front of a black background.

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 syncmaster 204b


Yes. There is no vertical deflection. The circuit that controls vertical deflection is bad. This is an easy fix for a TV tech. Take it to the TV repair shop.
