Reno Plus won't boot

[BobFoster]

I have tried Lou's "Bios" set up and that didn't work. When I start the Reno+ it will go as far is the "Casablanca Renommee" screen with white back ground and stop. I have tried three different HDs with the same result. These hard drives work fine in another Reno+. I've unplugged the unit, disconnected all wires, and even tried re-installing the software disk. The result was a message that "no hard drive was detected to install the software." I took the cover off and check the HD connections. All were "glued" in place with some sort of clear hard substance except one multi pin connector. I removed and replaced it with care to be sure it went all the way in. The HD connector inside the unit visible from the front doesn't have any bent pins. I Re-assembled and no change. The unit stops at the Casablanca flag screen. Any other suggestions beside calling boulder?
