Line, faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.

The resolution on this was to check the surge protector the television was plugged into. Once we unplugged and plugged into another surge protector, the screen went back to normal and the appearance was great. We believe this was due to one of the resistors within the surge protector may have become faulty.

other than a software upgrade. it probably a graphics chip malfunction and will need replacement.
These can be replaced but costly. Does it do the same if you use screen as a pc monitor?

Hi,
It could be 1 of 4 things:
1. One of the ribbon cables has worked itself loose (Simple Fix)
2. One of the assembly boards maybe faulty
3. The driver board which feeds the panel maybe faulty
4. The panel is faulty
The driver board in the UK costs approx £70 and approx £35-70 to fit it if this is the fault.
All other parts are between £80-160 and approx £35-70 to fit it if this is the fault.
The panel will cost approx 50-75% of what the TV was worth when you bought it - "Repair versus Replacement"
Thanks

Thats a pixel data problem, there's no data being sent to that row of pixels so they don't change color. This is a pixel address registry (PAR) issue and the PAR circuits need to be serviced its usually due to open or shorted SMT components on the PAR circuits. PAR also sends data, voltage, and control to each pixel, the green line you see are pixels that have voltage but because there's no data sent too them their all green because there's no control. If the pixels have voltage but no data or control they show up as green red, blue, yellow, or whit line vertically down the LCD panel. The vertical-horizontal section of PAR are controlled by 16 to 32 bit micro-controllers which may need replacing. If its under warranty take it back if not have your local repair center fix the tv for you...

That actually happened to a tv of mine once-i had some clear diet soda get spilled on front, I didn't clean it out(just off of screen) and I corroded the contacts on the lcd itself. if it is a recent problem get it cleaned/clean it yourself as soon as possible to prevent damage to screens connections. hope this was helpful, good luck.
