Hi everyone,
I've got a KDS VS195 monitor (FCCID EVOKD-1900) that's been working great for years. The picture has been getting darker and more recently out of focus (then BADLY out of focus).
Yesterday, the brightness level dropped to almost nothing within 30 seconds. As this was happening, the picture also was going out of focus.
As the brigtness goes down and picture out of focus, the size of the picture does not change, so the deflection circuits and voltages seem ok.
I don't have a schematic, but from the block diagram, it says "Double Focus" on the flyback, and there's also a "Hor Ver Dynamic Focus" circuit.
The video circuitry appears to be working as I have a KVM switch and you can hear the monitor go into standby if the 2nd PC is off. Likewise, you can hear it come out of standby when switching over to the main PC. Interesting note here, you can hear the static build up on the monitor as it's coming out of standby, but it does sound "softter" than normal.
The catch is I've been googling tonight for four hours or so on this monitor and it's behaving perfectly! Go figure.
I've read through the prior posts on sci.electronics.repari, as well as a repair forum or two, but none of the previous problems matched mine.
Sorry so long winded, but I wanted to be sure to include as much information as possible.
Thanks in advance!
