almost curry kinda colour.

I have an *old* top-loader, beta format VCR I am trying to resuscitate.
Everything works, but when I play storebought movies, I get audio wow and
flutter, and snow across the screen about once each second.  When I play
back tapes I recorded long ago at the machine's slowest speed, ...

I have a 14" JVC TV which I purchased new about 2 and a half years ago.
Ever since I bought this TV, I've noticed a very strange problem with
it. When the TV has been on for about a half hour or longer, it starts
to give off an odor that is similar to a skunk or a latex glove. It's

Q506 + Q507 & 2 blown fuses and it powered up but is in the protect

My LG Flatron 915FT+ monitor has a weird problem.  Sometimes, the display
stretches horizontally and the brightness decreases.  When it happens, I
hear a relay inside the monitor.  If I hit it on one side, the picture
returns to normal for a fraction of a second.  The display ...
