How to disable defect columns on Plasma TV? (turn them black)

[Airjy]

I got a Samsung PN50C430 that has a bad panel / bad columns drivers;

About 3 inch from the right side there is half inch wide vertical stripe of white noise. I want to salvage the TV by watching content exclusively from a computer and using software to move the output to the left of the panel defect.

But the white noise of the defect columns is distracting and I want to shut those pixel off. I am thinking about cutting ribbon cable traces between panel and bonded columns IC to do so.

Did anyone do that? Will floating the signal line from/to columns driver by cutting them result in pixels not lit or is it exactly such state that create noisy pixels? Could floating the lines damage circuitry/panel (other than column driver)?

Thanks,

On the bottom of the set are the E , F, and G buffer boards. You can unlatch the panel connector that is in line with the defect. Maybe you will get lucky and it will return to normal, but thats unlikely.

This is a cheap set, there is no connector on the ribbon cables going to the panel, flex cables end are glued to the circuit board running at bottom of the set.

But wouldn't disconnecting such cable only remove video signal from panel anyway? I need the column to be switched off, not the input signal...
