Hello all,
First time post here. I've searched here and used up my know-how. I'm at a loss on how to continue with this. I really don't want to blown another pair of mosfets!

Is the schematic that I've been using, not an exact match, but I believe that it's close enough for this board as a guide.
Here is what was found on initial inspection.
CM809 47pf obviously blown open on initial examination
QM801, QM802 FQPF5N50C shorted
RM801 0.22 1W FR open
RB801, RB802 100K 2W open
Checked ICM801, ICP801S, ICB801S for shorts, all appear to be fine.
CM808 appears to be okay
Changed all the above bad components, power on bang! PooF goes the
magic smoke. QM801, QM802, RM801 all toast.
All other parts that were changed are okay. Obviously I've still got a nice short somewhere...
Any help or pointers in the right direction would be appreciated.
