all 8 switches cycle through in switch test without me touching anything. Seemed the easy fix was reflow large header pins on opto board.
Put back in game and still happens....test dongs and all those optos come up in test....
Since I cant buy that board anywhere what can I troubleshoot next? It also blew f116 last night while we were looking at issue....put new fuse in and it does not blow but problem still there.
I pressed wires firmly in connector but no change. What can I check next? Connector on power supply board? Could a single opto cause this or do I start with whats common to all of them?
Thx
