Usually caused by the main driver board for the panel, or on the back-plane of the panel. The common solution is to change the driver board. If this does not work, then the panel would have to be tried.

It is possible in some cases the fault could be caused by the interaction of other boards, or can be on more than one of the boards. The factory service will use the process of elimination to locate the fault.

Service on these sets is done with board swaps, just like with computer service. Once the board is exchanged the new board may require some calibration to be at specs.

There is a red dot near the center of my Vizio tv screen, what is it?


if just a single tiny dot it is a bad or defective pixel in the front panel-usually there from first time the unit is powered up but from a distance may not be noticed--almost never gets worse or increases in size. Unless set is under warranty do not worry about is as a Panel(entire front screen unit) usually costs more to replace then the entire TV.

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!

According to Sharp it is a software problem. Engineer came, installed software update ,10 minute job.....TV worked fine for 1/2 day unfortunately: Then images turned black and white in all channels TV turned itself off, and stanby and OPC buttons started flashing. When TV came back on its own 10 mins later , screen had 2 large square staines superimposed in image (as if it was a burnt screen)...Engineer will be back next week...all quite sad really for a new TV.....will keep u posted

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.
