Hi to all,
Hi @Bigboss80,
The CRT filament is powered by 15.6KHz pulse from a winding on the flyback transformer. Unless you use a meter capable of True RMS measurement, other types will give a +/- meaningless value.
Unless proved otherwise, your CRT heater is probably receiving the proper voltage/current. Is the neck glow a normal red/orange color?
I would investigate the main chopper power supply, on transformer T624's secondary, is the 120V DC line at the proper value?
Other members here probably have experience & advice about this Sony BE-2A chassis and ideas as to why your image is dim.
Best Regards
