We had a power surge, a rather large one. It trip most of the breakers

sure everything was ok) stated that most of the TV's fuses did their
jobs and that I should just open and replace them.

Not too sure, but I did open one of them, Toshiba 14" 14AF46 (< 6
months old) and the fuse where the power comes into the board was
blown. It is a 125V/6.3A. My background is with computer boards from a
PC side and not with TV's. Before I go and waste my time and make the
repair more costly, could it be as simple as replacing the fuse? If so,
where would one normally purchase these fuses, not a common type.

The only TV that turns on still is a Sony KV-36XBR250. The image is
black and gray(can't really say white) and everything looks like a
hazy, reversed, indented images. The sound is fine. Is this TV toast?
Better to trash and replace?

I have replaced fuses before on two older tv's several years back, but
I am not sure about this newer TV.

Any advice is greatly appreciated.

ER -

Replace the fuse *once* with one of the *correct* rating and try it. If it blows again then you have further damage.
