It sounds like your LCD panel may have failed. First thing you should check is that all the internal connections and wiring are ok and just re-seat any connections for the LCD.

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.

So I have a 50 Lg ( LG 50LN5700). There is still a picture however about every 3 seconds it goes from regular to blurry and repeats. There seem to be about 3 black lines across the top horizontally about 3...


To clarify, are the 3 black lines horizontal (left to right across entire width of screen)? or are the 3 black lines vertical (top to bottom across entire height of screen)?

Horizontal lines are almost always the result of a failed panel, and no board replacement will fix the issue.

Vertical lines such as you have described (only 3) are probably also a bad panel. If the black lines were evenly spaced in a repeating pattern, it could be a mainboard or TCONN board.

Has this panel been cracked? or perhaps cleaned recently with too much water or cleaning solvent that has gotten the screen wet?

You may have to sell the TV for parts.

I have a brand new tv , but the screen shows a white line across and a red line down the screen?


Fault is with the TV. Contact the authorized service centre. Do not do anything by yourself; as it void the guarantee. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Line, faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.

I have one horizontal line running across the entire screen


It was not software problem, may screen or screen connecting cables may damage - change it at your nearest service centre

Horizontal line across screen


HELLO
This is called "Field Collapse". Line collapse is different (a single vertical line) in the centre of the screen.
But field collapse is usually a fault in the field circuit (possibly a field output IC has gone short circuit) or electrolytic capacitors have dried out. The same can happen in a CRT TV - looks as if LCD panels are the same way! I think you will have to take this to a service centre.
GOOD LUCK! (:-)

SAmsung has two white lines across screen with no picture


If the 2 white lines are in the centre of the screen it sounds like you have a fault called 'field collapse' . The 'x' or horizontal circuit on the tv deflects the beam across the screen which in your case is ok because the line runs across the screen ok. The 'y' or field circuit on the tv deflects the beam down the screen. Without a circuit diagram for your tv i cannot point to individual components.

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?

No picture or just one line across screen on hitachi ultravision rearproj.


Could be a loose connection on the printed circuit board in the Vertical deflection circuit.
You would have to have a qualified technician to repair this problem.
A intermittent connection in the circuit described can cause a horizonal line across the screen.
You have to be careful and not leave the TV on for a period of time with a bright line, as it can actually burn a line on the CRT screens, which is permanent.

Color line across the center of a black screen


Hi. this is caused by dry solder joints on the frame o/p IC. Resolder all legs of frame chip. Should sort that out.
