Ah, well that's too bad, well I guess it would make a nice displaye piece if nothing else.

As for my Montgomery Wards TV the Brightness has to be turned all the way up in order to see the picture otherwise you can't see anything, I was told that it might be an adjustment on the Flyback that needs to be adjusted (screen control?) but other than that I'm hoping that the picture tube isn't about dead on it because that would be rather odd for a TV that saw little use to have a failing picture tube already, especially when the color is fine yet just the brightness is a little off for some reason on it.
