Thanks to Jarl OZ9MO my SR620 is running fine again. He pointed me to the manual where I found this. "If the UHF prescaler of channel A is selected when the unit is powered off and then on again, the unit will display "TEST ERROR 34". This error may be corrected by deselecting the UHF of channel A. To run this procedure, press input button of channel "A" until UHF is not highlighted. Then turn the power off and on again." That's just crazy, but that was the problem.

Time-nuts, My SR620 has started reporting "test error 34" on power-up and will do nothing after that. Does anyone know what that message means? I have a reasonable lab and I would try to repair the unit myself but I have no documentation. Is service documentation available or should I just ship it back to Stanford Research to get fixed?
