Get the datasheet for the PWM chip that the power supply uses, look at
the sample circuits. Look for the kickstart circuit which almost
certainly will be identical to the sample circuits on the datasheet.
Check the value of the resistors and replace the small capacitor.
It's a daughter board with an ASTEC AS3842 which is sadly a mixture of
surface mount and through hole stuff which makes repair impossible for me
- I don't keep any SM spares.
There's plenty room inside the case so I might just fit a slimline PS from
a desktop PC - I can buy a new one for about 30 gbp.
