I received a Televideo TS802 "All-in-One" computer today. I always inspect computers before I turn them on to make sure there are no broken parts or screws have come loose and could short out a circuit board. Everything looked OK so I turned it on. Light on the floppy drive came on like it was trying to boot, but there was nothing on the display. The neck of the CRT was glowing which was a good sign, but the high voltage section was down. If the high voltage section is operating you can tell by the static charge on the front of the screen.
Upon further inspection I found a Motorola K1114A 23.814MHZ crystal oscillator in the bottom of the case with the pins broken off. Turns out it is the oscillator for the terminal section of the unit. Since the horizontal sync signal is derived form that oscillator, I believe this may be the reason there is no output from the flyback. Anyway, the display is completely dead without it.
I am not having much luck in finding one of these oscillators on the net. Does anyone know of a source for these parts?
