did you get the schematics as i need it to

If you are talking about the PVC computer for the Hitachi EX120-2, I have one on my desk right now I'm trying to fix.... The diode, labeled D1 is in series with a 4W 10 ohm resistor, on the Father-in-laws machine, which I have to fix the resistor was blown open and the diode went short circuit, so I have had a massive overload there to do that. The diode has no markings, but if you consider the power rating of the resistor, then the max current would only be around 0.6A( for max power rating on the resistor), but it seems to pull only 0.15 to 0.22 A on normal operation, so just about any generic diode probably would work. I used another glass passivated diode rated at about 1.5A that is just a fraction larger than the original, but any 1A diode should work. If you have a simular issue to me, then I'd be interested in what else you find. My email is a few posts back. I replaced the resistor then it all worked fine in the machine for over half an hour of hard work, then suddenly blew again. I'm an electronic tech but I cant reproduce the fault. However, the computer is still faulty. (tried in another machine)
Does anyone have the schematics for these computers? Or a cheap second hand computer!
