ICOM-751 dead, help

I was using my radio just fine, than I unplugged it and moved it a few feet
and now it is almost dead. I can hear a relay engage when I first turn it on
and fall off about 10 seconds after I turn it off.
What happened?

Burt, the first step would be to check the voltage output of your
power supply under load.

Burt if you need a schematic or block diagram for that radio let me know.

If it has never been replaced it is possible that what happened is that you had
a battery failure in the RAM board. There is a resonable chance that unplugging
the radio and moving it was just the last straw for the old battery. This will
leave you with a very dead radio.

See the following for details....

Also it is possible to change the battery and reprogram your own board but it
may be a little involved....

I think you can still send them back to Icom for battery installation and
reprogramming as well.

I would suggest a Google search for - Icom 751 memory board - there is a lot of
information out there.

The 751 will still power up without a ram unit in it. You just can't do
anything with it, strange stuff on the display etc.

I've worked in repair shops too, and noticed people's descriptions of
something being "dead" often leave a lot to be desired.

"My TV is dead."
"Oh, is the picture completely black?"
"Uh, no."
"Well what does it look like?"
"It's all fuzzy."
"You mean blurry?"
"Uh, no. It's like sand."
"You mean snowy?"
"Uh, yeah. I guess."
"And is there no sound at all?"
"No. It's fuzzy too."
"You mean people are hard to understand?"
"No. It's like the picture."
"Oh, you mean just a hissing static sound?"
"Yeah. Like I said, it's dead."
"Do you have an antenna or cable system hooked to the TV?"
"What's that?"............
