This failure phenomenon of kinescope accelerating voltage on the low side. Check the accelerating voltage reduction. wanservice manual download site
(1) the multimeter test tube accelerating voltage, voltage fluctuation between 100 ~ 400 v. Breaking operation output main put plates lead, test the lead on voltage and 420 v is normal. Accelerating voltage load has a fault. wanservice manual download site
