Got this from a friend who found it standing at the trash.
Very recent model so worth fixing.
Bridge rectifier had 2 diodes shorted, replaced all 4 to make sure.
Measuring other parts in the primary section, no shorts.
Plugged unit in and bang, fuse in bits.
Strange but in the input is no short, so fault on the secondary side?
Is it possible that a seconday power supply fault causes the fuse to pop
with such a laud bang?
Any pointers i should look at, i will check diodes, zeners, transistors and
HOT just now.
Anything i may be missing?
Yes, checked the filter cap, is fine.

You could start by mentioning a model number. If it is a Funai made
unit, it is mostly trash anyway so may not be worth repairing. If it's a
Philips built unit however, repairing can be worthwile. You could also
try consulting nl.hobby.electronika
