There are vertical lines on my LG RT-20LZ50 lcd tv screen. It looks like bar codes. First it start from the right side of the screen. Then it spreaded 3/4 of the screen.

Pl help me!!!!!!!!

buddy.. it seems to be issue with the strip running from the main board to the panel.. can be more.. but most probably the strip..

+1 it could be that.My viewsonic lcd monitor does give a single line,but if i tap the monitor it goes away.Happened ever since the viewsonic repair guy opened the lcd monitor ,to replace a OSD button panel board.

It could also be a problem in one of the components in the T-CON board.

This kind of issue can happen if the very delicate FFC cables on the
LCD screen are damaged. As they are so delicate, even slightly
mishandling it when you opened the set can cause it.

Sadly, replacing the LCD may be the only option.

It may be possible to delicatly shake the FFC cables to figure out
if it is loose contact, and then use Silicone glue to hold it in place.

Another possibility is static damage to TCON board during your repair.

Better call lg technician and know the problem ,most of the lg lcd delicate spares are not available in local market.
