RE: [Repeater-Builder] HP 8920 Service Monitor Help

I'd check the classified ads in Communications or Two Way Radio Dealer magazines or other trade periodicals, there use to be a number of adds offering repair and calibration services for service monitors.  It still may not be a cheep repair, but its bound to be much less than HP factory repair costs.   Rob  K7EI -----Original Message----- From: Scott Zimmerman [mailto:[EMAIL PROTECTED] Sent: Monday, November 17, 2003 12:29 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] HP 8920 Service Monitor Help My HP 8920 Service monitor has suffered an overpower condition to the Antenna IN connector for apparently it's last time (Accidental of course!!). Does anyone have a "real" component level service manual on this Monitor?   I have a manual that calls itself an "assembly level repair guide". That's all fine and good. Following it has told me that the problem is in the input/output section (A23). A call to HP for a replacement module sat me on the floor for a few hours!! They want as much for that module as I paid for the whole monitor!!!   I'm sure it's a relatively simple fix with (maybe) a common part, but without any board level docs. it's hard to say. I have disassembled the module to look for any burnt traces or parts blown off the board, but everything looks OK. I ran a few simple ohm meter checks, but with a multi-layer board, I can't tell where some of the traces are supposed to go.   Has anyone run into this before or know of a decent person to deal with when it comes to repair. I really on this monitor on a daily basis, and it's completely usable through the other 2 ports, so I'm not really enthused about sending it off to the repair shop for a few months.   Scott   M.
