Jerry,

There are pdf files of the Coco3 service manual at
ftp://maltedmedia.com/coco/MANUALS0/TANDY/HARDWARE/COCO3/
There is a troubleshooting section, Section VI, which will walk you through some 
step by step procedures with a voltmeter and scope, if you have one. You should 
be able to determine if there are any grossly wrong problems with the Coco3.
It is very unlikely that anything would go wrong with ROM paks if they have not 
been opened and the ROMs removed. As already suggested, check the ROM pak 
contacts for oxidation.
