pumping 240 into it wont have done all that much damage, most likely just wiped out the PSU section..
I've repaired countless chassis that have been run at the wrong voltage without much trouble..
schematic wanted for sanwa pm1745 monitor

im hopeing its just the filter cap in the psu section as this is well gone
as there seems to be no schematics for this chassis ill just have to sitdown with it
this is only the second monitor ive tackled since going for inhouse repairs before sending out SMPS and simple PCB repiars to date
so an odd mistake will happen as long as we learn from it!

Update
for the wrong voltage input only damage seems to have been
C806 200v 680uf capacitor and R807 470k ohm resistor
only other faulty parts were
C441 250v 1uf capacitor and C424 50v 1uf capacitor
fitted the chassis into a dance stage i found with the pm1745 unit in and all works fine still after 2 days
checked C441 on the chassis now out of the dance stage and thats shot too

I'd like to wish everyone a happy Xmas and in these hard times some success in the new year
on a sad note we had our machine store torched the other night mostly old fruits used for spares but some videos lost included
sega harley davidson twin upright
sega star wars trilogy deluxe
sega daytona twin
sega rally championship twin
sega virtual soccer
namco time crisis 2
track & field
beach head 2000

none perfect but many spares lost forever
