[cctalk] IBM/RT help

Hey folks, Now that I'm done moving house I have time to wrench on the 6150. Before moving it worked; you'd power it on, the LCD status countdown would get to an OK value, but the CRT wasn't legible. I figured I'd be wrenching on the CRT. Instead, now when I power it on, it powers on for a second or two and then shuts off. I'm assuming this indicates a short or power-draw somewhere. I've reseated the CPU and RAM cards, the peripherals, and unplugged the hard drives (2x ESDI) and floppy in case they had a fault that was drawing too many amps and causing the power supply to shut-down. I noticed nothing on the CPU or RAM boards (exploded caps, etc.) What should I look at next? -- -Jon +44 7792 149029
