I have checked diode and the two main drivers on heatsinks but a gegeral opinion poits to capacitiors and no way to test these so cant check votages at mo.further A/S have changed names and dont have their site working yet
Been on net but no one has this unit ie partsmaster ect
Cheers old bean

Hi Feenix,
Thanks for the pic - haven't seen one exactly the same but last similar one I met had a duff chopper driver chip, think is was a SG6841SZ.
Attached your pic - Chris.

-------Yup no one can identify or supply this board! ref that chip----
Is that the small black chip with 2 legs front and 2 back? says IC2 see it on top of transformer (no IC 1 anywhere)
Also there is a diode near one heat sink --see-- near power resistors on left hand side-- at the bottom it was like carbon but cleaned it off looks ok not shorted or o/c may be a zener but get sucker tomorrow so can remove and check it prop all capacitors look mint so who knows
feenix:
Thermistor near top coil left h side in black is shorted heat makes no difference to reading this could be the culprit as probably anti-surge? MF72 5 D11 and looks like Ic1 is under board
Cheers
