I've got an InFocus LP435z DLP projector that's driving me nuts!

The lamp (HID type) intermittently fails to ignite. Sounds like a bad lamp but it's not - the problem is it doesn't even
*try* to ignite. The unit makes a distinctive noise when the "starting" circuit is going and when it's in a bad mood there's
no noise. I've managed to track down the signal from the logic board to the PS that tells the lamp to start and hooked an
LED to it - from this I've determined that the problem lies in the supply because even when the lamp doesn't start the LED
lights. So what I need at this point is a schematic for the power supply (which is a custom unit).

I know from Googling that InFocus usually isn't very forthcoming with schematics - just wondering if anyone here has found a
source for same? Or, anyone ever had a similar problem and had luck fixing it?

Thanks!
