I have a SONY plasma TV. It's developed a problem - a thin horizontal
black line that goes from one end of the screen to the other (about 4"
from the top of the screen). I've also noticed that several other
people have reported the same problem. I've even seen folks selling
their plasma TVs on ebay with this same problem.

The bad news is that I am told by service technicians that the problem
is a bad display driver board, which is part of the display panel.
Cost to repair: $2,000.

My gut tells me it's a bad chip somewhere. I shouldn't have to replace
the entire display. Correction - I shouldn't have to throw a $4,000 tv
in the garbage after three years.
It is not inherently impossible to fix.
I'd estimate you could probably set up a station to try to fix it for
well under 10 million dollars.


If you could find an identical panel with a broken glass it might
technically be possible to transfer the driver from one panel to the
other, but with the ones I've seen there would be absolutely no way in
hell of doing this at home. It really is a shame, I don't understand
why they bond them rather than just using some sort of connector.

Didn't we just discuss the political issues in adding 25 cents to the
cost of a product? Could imagine how many levels up the chain of management
would be needed to add a few dollars worth of connectors? :)
