Hello everyone.
I am working on an old CRT TV.
The TV set does not start at all.
I have checked the smps, and the 800mA fuse ( SI624 ) on the shematic , near the main capacitor , keeps blowing .
I changed the electrolitic capacitors on the primary side,
changed the TDA4605 and the PowerMOS transistor.
All diodes are OK and 300 volt is measured on main capacitor ( C626 ).
The PowerMOS transistor seems short circuit and the fuse blows.
I have attached the shematic of the board.
Any help will be appreciated.
Thank you very much.
