Hi guys,
looking for some knowledge.
One of the big blue Caps let go the other day (3200 uF) so I replaced both of them with 2 new units (3300uF). Everything meters out ok except for the Ch42 Converter monitor voltage. I have 295V at the Caps/ Diode stack and into the SEI01 board. This should translate to 7.4V-7.5V at ch42 (to match CH43) but I've got 6.2V with the trim pot all the way up.
I'm not sure why the Cap let go, possibly age but may be this also has something to do with it?
Has anyone experienced a similar issue? Any suggestions on where to go next to test the monitor circuit and how the 295V gets conditioned?
thanks
Mick
