THE RIGHT HAND SIDE OF MY LG LED TV IS COMPLETELY BLACK, WHEN I TURN IT ON I SOMETIMES GET VERTICLE LINES ON THE RIGHT HAND SIDE BUT THEN IT JUST GOES BLACK. THE LEFT HAND SIDE IS WORKING FINE ITS JUST THE RIGHT HAND SIDE
THIS set uses 2 boards inside--one drives the left and the other the right side of the screen.
You have to id which is which (GOOGLE?) AND replace it-every brand has different names for these but it sounds like your problem
Some research (you or me) should give a board breakdown for this model---not looking for main or power board but another like sustain etc. and there will be 2 listed (for right and the left sides)
SOURCE: There is a big black verticle line on the screen
vertical lines in general are caused by the data boards (buttom of screen) theres a left one and right one these boards are atached by ribbon cables going to the logic board .first all ribbon cables must be checked and reconnected to make sure there well seated ,also pass compressed air ( can ) , if this dose not solve problem try slightlypressing on the connecters replace defective board , on many lg tvs the connecter on the logic board is defective slightly pressing solves problem ,if this does not work you have two choices the data board thats on the same side of the line is defective you may try to clean the brown flex connecters that plug to the data board these connecters are not easy to reconnect be delicat and patient !!!if data board does not solve replace logic board !
SOURCE: Flicker
I had the same problem with the flicker. Mine was a Flicker followed by a greenish line through the screen. It got worse then after 2 months the tv stoped working the power didnt come on at all. I Im taking it to bget fixed. The guy said it has somthing to do with a burnt out switch in the unit.
SOURCE: ORANGE OR RED VERTICLE LINE DOWN RIGHT SIDE OF SCREEN?
hi..the probelm is due to the video circuit board.
only when you have a problem with the video
circuit board you will get such type of faults.so
you have to check the video board immediately.
check it out..
thank u..

I had this problem on a 37" Viewsonic LCD. Pulled it apart and through a process of elimination, I traced the problem back to a small board with several flat white ribbon cables coming out of it. The board was near the top center of the screen and under a ton of other equipment requiring almost a total disassembly.
This small board was clean but I noticed one of the rubber standoffs had slipped down and was making contact with one of the outputs running to the LCD. It also happened to be the output running to the section of the screen with the problem.
I postulated that the sticky glue on the rubber standoff may have just enough conductivity to cause a problem. Moved it so that it was no longer touching anything electrical and then reassembled the TV.
Afterwards, I turned it on and was pleased to see the problem has gone away! If you're having the vertical line problem, then maybe this could be your problem too, especially if you have a Viewsonic since it could be a manufacturing defect.
