Hello,
I have a mario bros. with a sanyo ez. Monitor worked fine except for distorted top so someone tried a cap kit and now nothing happens. I am fixing this monitor for a friend and need some I help.
I have done the following according to the flow chart.
Tested Q902 black to monitor frame, red to HOT case with multimeter set in diode test I get a reading of 1.
I then tested Diodes D601-D604 with multimeter set to diode in one direction I get a reading of 1 in the other direction I get a reading of 530
I then measured B+ which was 35.5 vdc. I tried to use the B+ adjustment pot and it has no effect on the voltage. I pulled the boards and checked the solder points and traces and they looked good. Also I verfied the caps were installed correctly which they were.
Any ideas?
