Benq Q9T3 FP937s-D does not switch on
Hello to all and happy new year from Greece,
It is my first post in this super forum so mind me if i make any mistakes.
As you can see in the pictures the filter cap C605 blown and for sure C703 & C704 are bulged.
The monitor was working fine untill some flickering a blackout and power on again from the electric company.
The main fuse 2A @ 250V is not blown.
Can anyone give me some tips.(I know for sure i have to check rect bridge BD601 and Mosfet Q601)....
