Lightening hit my cable TV line, destroying my cable tv converter box,
all
splitters on the coaxial, and put a nice pink blotch on my TV screen.

In my other room, my PC was turned off, and plugged into my APC unit.
However I had my external USB WinTV unit connected.
So the lightening surge destroyed by Win TV unit went through the usb
cable,
destroyed my ASUS p4p800 E-deluxe mobo and my antec Power Supply.

All else seems ok...except my video card (Nvidia GeForce 6200) has a
pink
tone to everything and
blues are really really bright. Attempts to correct
the color with the nvidia display software did not work.
My monitor is tested and fine.

Is there any hope for my video card (which i bought 2 weeks ago), or
shall I
consider it garbage.

Any opinions appreciated.
Thanks VM

The monitor cable to the video card would act as a transformer.
The blast of energy flowing through the other wires, would
also created a high voltage on the monitor cable. There is a
good chance that damaged the output of the video card.

Have you tested your computer monitor on another computer ?
Are you sure it is not the computer monitor that is (also)
damaged ?

Yes the monitor is an NEC LCD flat panel and I have tested it with another
PC.
It appears to be working fine.


For your TV set, the blotch could be residual magnetism in the
frame of the set (I'm assuming here, that it is CRT based).
You could try finding a TV repair shop that has a degaussing
coil. I took my old CRT to a TV shop, and they waved their
degaussing coil around it, and removed all the discoloration
I had. The degaussing coil in the unit itself, was not
strong enough to remove the magnetism in the frame of the
CRT, but the external degaussing coil got all of it.

I suppose it is also possible to blow some of the phosphor off
the screen, but then the set would probably have been destroyed
too.

If the TV set is based on some other technology than CRT,
then degaussing won't help.


The TV set is an 11 year old CRT. Not sure if it's worth attempting to fix,
cost wise.

Thank you.
