Thanks to all who responded with some very good suggestions. I finally dove into it and found out the bad news - the power supply board is dead.
There are three circuit boards, a power filter board on the back of the frame when you open the case, the power supply board buried in a frame to the right (looking from the back) and the mainboard on the bottom. The power supply supplies power to the mainboard through 2 connectors - low voltage to a 4 pin connector at the left rear of the mainboard and high voltage to a 2 pin connector at the right front. There is no other power supplied to the mainboard or the picture tube. The low voltage should read about 15 VDC and 5 VDC and the high voltage 110 VDC according to the labels on the circuit. I get a big zero at all of them (actually 0.182 at one).
I pulled out the circuit board but couldn't find any obvious damage or bad parts. Nothing toasted, no bleeding electrolytics. There was a touch of corrosion at one spot on the back of the board, which I cleaned but it didn't make much difference. Looks like it's dead, I'm not going to go replacing the big electrolytics (what usually degrades over time in old power supplies) as they're big and pricey.
Oh well. I'll call the moving company tomorrow and see how hard they laugh since this one really probably died of old age at an inconvenient time.
Anybody got one of these (model 15RAM3) in their basement?
Thanks again, Stephen

My Radius Full Page Display refuses to power up. It was working before we moved this summer, and this is the first opportunity I've had to plug it in after it took a several thousand mile journey in a crate across the Gulf of Alaska.
There is no visible damage to it, nor was there to the box. Four other computer monitors and the TV survived the trip, so it's a surprise. I opened the case (taking all the precautions) wiggled all the connectors and chips, checked the 2 fuses I could find, but no kimchi.
