Thanks, I think you are confirming what I suspected. I can't even find a datasheet for what I believe are the LED driver chips (OKI M5837). Point taken about old dried out electrolytics.
Actually, I'm not trying to repair it. I'm wanting to turn it into a display item by animating it with a microcontroller. I can tap directly into the VFD chips and the LED bar, I was just hoping to reuse some of the existing driver circuitry in order to avoid having to duplicate existing circuitry (which I can do if all else fails).
Thanks,
Greg
