Hi AG,

Just a thought - the circuit looks awfully Profilo Telra in some areas where drooly caps and S/C zeners are always a prob - why not check around that 24v supply, as you have a similar one to compare.

All the best - Chris

Hi I remember one of my posts where I had a bush that used the same power suppy, I spent days on the think replacing, checkin, swaping parts between 12 and 24v supply on the board all with no luck.
In the end I found someone selling a second hand working board that fixed it.

Hello
I have this bush for repair it is dead, found 4x 1000uf caps bulging on the 12v line (replaced)
I have also tested for the following with no luck
R954, D909, IC901, all ok
To test psu add 6v2 zener from pin 2>1
there are 2 outputs on this psu 24v comes up and after a while dies away
and 12v (pin 2) only comes up to 1.3v
This psu has sprung into life once and ran with good output voltages.
I have swapped components over from the 12v psu to the 24v psu which are the same with still no luck.
