Hantarex MTC 9000 - High B+ / No Picture
« on: November 14, 2017, 12:20:45 pm »
Hi guys

More troubles! Was working fine one evening, come to it the next morning, no picture. From reading up my first suspicion was x-ray protection circuit.

With no remote adjustment board hooked up (sync, hold, amp controls) - B+ is 133v and I get a horizontal white line as expected

With remote adjustment board hooked up - B+ is 144v and no picture. Adjusting SCREEN makes no difference so can I assume x-ray protection circuit is in effect at this point? What would be likely to blame? I know 133 is a bit high but at least there's a picture. HOT?

Many thanks!
