Casio TV "green screen of death"

[etype2]

For what it's worth:

I have a good collection of micros. Many are Casio. The green screen disappears once a signal is imputed, or a common problem the OFF/VHF/UHF switch is bad or needs cleaning. Giggle the switch and the image pops in and no green screen.

Other times, the set just needs to "wake up" for several minutes after power is applied.

Battery compartment cleanup usually works.

That's not how they normally work. When there's no signal, the set is supposed to show a white screen with the tuning indicator at the right scrolling down as it scans for channels. When the green screen happens, it covers the entire screen, even the tuning indicator, which is supposed to be a permanent fixture of the display.

When my TV-400 started to fail a few years ago, I did indeed observe that it would take a few minutes to wake up when you turned it on. Then eventually the green screen became permanent.

Your exactly right. Just acquired a Casio TV-7. Unpacked it, popped in batteries and had the green screen with active scan. Attached my DCB and boom, nice clear signal with sound on Ch. 3. I've had other sets do this as well, but still work. I guess I don't use them enough to watch them fail.

These sets are so cheap on EBay, not worth my time to try and fix when one of them fails, I just get another one on EBay.
