Hello,
Managed to fix the CRT monitor chassis of a Photoplay cabinet.
- Recapped C614 (2.2uF 100V) C1 (220uF 25V) C106 C705 C720 C704 (100uF 35V and 50V) --> fuse still blew
- Changed the Flyback (the old one looked burned, deposits where on the heatsink next to it) --> fuse still blew
- Changed the faulty bridge rectifier --> fuse still blew
- Took out the PTC --> monitor worked!!
But brightness control not working, need to replace Q807 / Q808 (2SA1015) because one of them tested NOK.
Now I have a working monitor with strange colors.
PTC id: NICHIAS 180N271 910. Cannot find any info, any ideas for a cheap replacement part?
Degauss coil reads 11 Ohm
Thanks,
Anton
