Hi all
My usual M.O with this issue is to replace all of the rectifier diodes on PSU secondary side , including the 2 troublesome SK39 SMD types .
Hasn't provided a cure this time , which i'm surprised about .
Also tested ESR of all the electrolytic caps
Any help much appreciated .
Note , customer in his infinite wisdom brought the unit into the workshop half stripped down , therefore there is a possibility he has added to problem .
