Usually this problem is associated with the LCD Screen. The screen is made up of many layers in a matrix form. If there is any separation, no mater how slight ....it will cause the mastic in the screen to break connections. This can be caused by manufacture defects...which is hard to prove. Common causes is someone unaware what happened pushed the center of the screen causing it to flex a minute amount there by breaking the mastic or matrix if you prefer.......replaced screen and corrected problem. That is the most common cause, however as with any problem; other issues can cause the same effect.

The cable (data) comming off the logic board to the screen can have a loose or dirty connection; there by giving the appearance of a broken mastic. In which case unplugging and replugging the cable in and out several times should clear this up.

Last but not least is the logic board. There is no need to try and repair this. Replacement is the way to go. Why most of the logic and data chips have so many connections that special equipment is need to facilitate repairing the board.

Hope This help.

Hello; The width of the line means everything. If the line is razor thin, meaning one pixel wide, this is is very likely a bad LCD panel ( costs more than the TV sold for ). If the line is much wider say 1/2" give or take, the problem is the LCD controller or LCD timing ( same thing ) PCB. Much more less expensive! John

HDMI Closed-Captioning won't go away

I bought this television yesterday, bought the HDMI cord and hooked it up through my Comcast digital cable box. Every channel would display closed captioning, despite it's supposed inability to support that function. In order to remove it, we had to turn off the cable box's ability to display closed captioning. To do that, turn off the cable box and hit menu to get to the setup menu. It is there that you will be able to turn off closed-captioning.

Try a reset to this TV and check. There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. 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/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

It's the fuse in the electric engine. You can bypass this fuse by cutting it off and then you just connect the two ends together, wrap with electrical tape. It'll work, that's what I did to mine. Works great again

A lot of people are confused about turning the TV 'off'. If there is a light showing when the TV is 'off' it is merely on 'stand-by' and not truly off. Off means being physically turned off by either the switch on the set or the mains. using the remote to turn 'off' the TV will not turn off it will only put the set into stand-by mode. In many cases if the TV is in stand-by mode, and then switched off, when the set is turned back on, it will still be in stand-by mode, and will need to be turned on with the remote. (even if you unplug, in some cases) All TV's are different, so will operate differently of course.
