You guys sound real experienced...
How about a little troubleshooting advice for FGRV?
Has anybody checked to see if it's plugged in?
If it is, somebody could try thumping on it up top there next to the rabbit ears.
If that doesn't work, reaching around back and unplugging the phone line, counting to 10, and plugging it back in might do the trick.
If somebody spilled coffee on it, it might come back on all by itself once it dries out.....
E-How says it's probably the carburetor, but I think that the system upgraded to fuel injectors a few months ago, so that can't be it.
