I have has it with these VCR's that turn the screen blue when the
signal gets weak. I live in a rural area and am used to weak
reception, since the nearest station is 60 miles away. Having a signal
get fuzzy and losing a few words of the sound is not that big of a
deal, but when I am watching something, or worse yet, taped something
and that god damn blue screen keeps popping on and off is more than I
can take. The first VCR that did that I threw in the trash. I
thought it was just a bad VCR. So I buy another one and it did the
same god damn thing. That one got me so angry I threw the ****ing
thing thru the livingroom window, which cost me almost $100 to repair
the window. I just bought an old one at an rummage sale, hoping it
would not have that ****ing blue screen. Wrong, I just tossed that
one out the door, only 5 minutes after hooking it up for the first
time and it's in 10 or more pieces on the lawn. The asshole that put
that into the VCRs should be hung in times square by his ****ing cock.
At least they could have put a disable switch somewhere on the thing.

Is there a way to disable it?

I've never worked with a vcr which didn't have this as an option in
setup menu.

If you really allow a machine to get to you this much, are you sure
you should be allowed near mains electricity? And other people? :-)
