How do I defeat VCR's blue screen?

S

Scott Ehrlich

Guest
I have two different working cable-ready consumer-grade VCRs I use for
cable (they also act as the cable converter).

If I flip to a channel I shouldn't get, since the tuner cannot lock onto
a clear picture, the VCRs flips to a blue screen. How do I defeat the
blue screen on either VCR? The VCR menus are very basic, and the
external switches are few. I presume there must be a switch, maybe
inside, to permit me to see the scrambled or poor quality picture
instead of the blocking blue screen.

One VCR is a Panasonic, the other is an RCA. I've seen the same effect
from many other VCRs, and some cable-ready TVs, too.

How can the blue screen be defeated without the use of an external cable
box?

Thanks in advance.

It is almost certainly hard-coded into the firmware.
I doubt very much if there is anything you can do to
change that behavior short of re-writing and retro-
loading the microprocessor code.
 
If there is no option in the user menu, there is no easy way. The software
for this is written in to the firmware code of the uPC. Get a colour black
source such as from a TV sync generator, or use a video camera with the lens
cap on it as a black source going in to the external input of the machine.
As long as it sees video coming in, it should not give you a blue screen.

Nothing you can do with VCR or combos. But you do have choice with TV
JVC sets that I know for sure. They have option for noise muting,
turn it off gives you snow or a noisy pix instead of blue.

My (old) Mitsubishi HS-U770 has a switchable video mute as a menu item. Most
VCRs do not.

I would guess that the hardware, mainly the signal level and squelch,
have a lot to do with this.

I have an LG TV which has an option that turns off the TV after a time (10 mins
IIRC) of no or bad reception. Otherwise it just stays on the noisy station.

How is that supposed to help? he can't see what he wants, so you want
him to hook it to a different video source?

Yeah - try getting MacOS to crash. It seems pretty stable.
