Re: image flat line
Vertical sweep failure.
It will be an I.C. with a part number that probably starts with an LA_
_ _ _ and be on a heat sink in the vicinity of the connector
going up to the yoke. Try replacing that. But first, check
all the electrolytic caps around it for testing dry (sorry - takes a
special meter to do it in circuit) or just replace them. May have
lost power to the I.C. as well. Look the I.C. up in the
free NTE crossreference at nte.com get a diagram of its pinout to find
what pins the power and outputs are on.
Hope ya fix it!

Visit this site named 'Electro-help' These type of fault to plasma TVs are described in detail there. Almost all plasma TVs will have same structured circuits. You can find which board to your TV is faulty, by referring details from this site. Check this link, and select the site named above. Pull up older posts there.
Does it look like a burned in image? If so and if you have a brand new samsung tv, it should a scroll bar that cleans out the screen. Go through the settings and this should fix it. If it is last years model or older you may not have this feature. Go to a channel that is snowy, scrambled picture and leave it on for couple of hours. This should some what make it better. If it is not a burned in image it could mean that you have dead pixels. Unfortunately this is not something you can just fix. I suggest contacting your manufacture. I hope this helps, if not give me a feedback. Good luck.
These lines came on to the tv LCD screen panel by itself?Yes,than the board that call the T-CON board it is dying to causes this problems,if these black lines problems causes by u or an object by hitting it to the tv LCD screen panel itself,it can't be repair,the tv LCD screen panel itself it is dead and leaking radiations.This T-CON board sit in the middle at the bottom of the tv LCD screen panel.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish T-CON board for the replacement.

You have a vertical output IC that needs repaired. You may need to only resolder the vertical output IC. If then you do resolder, you will need to check and replace any capacitor in the immediate area of the vertical IC. A weak or bad capacitor will heat up the IC, and create rings on the pins under the IC. Also check the solder grounds on any resistor and diode that are immediately near this IC. This will bring your TV back to full view. Thanks for asking and show a few hands of support!
That sounds like simple ring-cracks in the vertical circuit, most likely the vertical Ic itself... On the printed circuit side of the Tv look at the vertical Ic and examine it carefully under some magnification where each pin of the Ic solders to the board. See if you can find any cracks in those solder connections.
Your convergence ICs Stk-392-110s Replace Both ICs.If 110s use 180s if 020s use 040s other wise Go by number on ICs .Mat electronics has parts 1-800-628-1118.Thats Cheap for 300.00 if you only have to replace ICs! Check all resistors around ics replace them if burt/read bad.RK42 3.3ohms RK46 1.8 RK50 2.7
RK54 1.5 RK58 3.9 RK62 2.2 ohms.
Hopefully you still have under warrantee. If not, sorry. This line if memory serves me right is because the tv has 2 picture panels on each side of the TV (they join up together to make one picture). Toshiba did not realize that the panels will start slipping thus creating this fine line from the top of the screen to the bottom. They have revamped the newer models and placed glass to adhere the panels together. Even though my TV was under warrantee I got a new one and have had this one for 1/2 year and now the picture just blew (there is sound but no picture.) Take your TV back if it is under warrantee.
