MRS-1608 won't boot

My MRS-1608 won't start up. The screen illuminates but doesn't show anything. I thought it might be the hard drive, but having replaced it with a formatted 80Gb Seagate that I know is good, and searched endlessly until I found my factory recovery CD, it's still the same.

If I hold "clear" when I power up, nothing changes. There is still no display on the screen. Nothing to access the CD drive, which won't even open without using a paperclip. It won't turn off unless I unplug the power jack.

I've browsed through the forum and can see a few people have reported the same symptoms, but I don't see any solution anywhere.

Any clues? I'm competent with computers and electronics.

I would start by looking at the power supply as the MRS-1608 essentially is a dedicated use computer. Hard drives and CD player burners require +5Vdc, +12Vdc and -12Vdc to work. Everything else relies just on the +5Vdc.

The United Kingdom website, Tom's Hardware, has a nice article about checking voltages with a multimeter. The article is available here: ... 38-11.html

If you don't have a multimeter but often play around with computers as you indicated you did, then consider a Insten 20 / 24 pin computer power supply tester. They are available for way less than $10 US. Here is one from Newegg (I just purchased after seeing the price!): ... 000V-001P3
