thanks for all the responses. is there anything available online showing me the location of all the components at least?

if i associate an unfamiliarity of system specifics with inability to repair equipment i would have been out of business looong ago. theres nothing complicated about it once you have the system specs, and over the years ive found that it will never get repaired if you dont start turning wrenches. besides, i would just feel dirty paying someone else to do what i do. ;-)
