Samsung UA49K5100 vertical bar

[pronester]

Hello guys,

i have Samsung UA49K5100 with a quite visible vertical bar on the left side of the screen (refer pictures, marked with a circular thingy in the picture)

Anyone had similar problem and managed to fix it? appreciate your assistance on how to go about this..

just to note that i have tried the tape method but can get the bar go away.

Thanks.

1. Please post detailed pictures of back side
2, Measure width of that bar vs width of the screen

Re: Samsung UA49K5100 vertical bar

One or more incorrect gamma voltages are causing this.
They are generated on t-con and common for all cofs.
You have to look at the cof corresponding to problem bar, take a picture of it.

I see the pictures you posted, it should be that cof.
Gamma voltages are GM1 to GM14, measure all of them and look at connections.

ic..if you mind.. where are the points to test with multimeter? and what is the normal voltage?
