Extra flyback! Oh I'm not sure, let me check and get back to you.Tomswork wrote: 25 Jul 2020 18:41 @rubber_jonnie
Those rifa caps are evil the smell. Does your monitor have the extra flyback on it ?

I seem to remember there being an adjustment on the analoge board for the output voltage.rubber_jonnie wrote: 25 Jul 2020 10:16 So today it's the turn of the analogue board, since it's only giving 4.3v on the 5v rail. I have a box of capacitors ready to be installed, but it does mean one thing, I need to remove the analogue board and that means discharging the CRT, something I've never done before.
I expect there is, but the caps were pretty terrible, leaking badly so I'm getting them replaced first. The Rifa caps were split too but I didn't find those until I removed the analog board.stephen_usher wrote: 25 Jul 2020 23:47I seem to remember there being an adjustment on the analoge board for the output voltage.rubber_jonnie wrote: 25 Jul 2020 10:16 So today it's the turn of the analogue board, since it's only giving 4.3v on the 5v rail.

OK, appreciate the warning. Fingers crossed when the caps are done, voltages will be back to normal and I won't need to adjust them.Tomswork wrote: 26 Jul 2020 00:05 Just be careful. If there is an extra coil by the flyback it will be hot when your adjusting the voltage. It is fed off the transformer output directly.

How bad can it be?
