Default Expert help needed for Tektronix 577 Curve Tracer

Dear All Expert,

My Tektronix 577 curve tracer has been working in the previous couple of years. Recently the CRT beam sometimes come off. Sometimes, I can get the beam appear by switching the switch on collector supply and the test fixture. But, now, I can not get the beam back again.

I think it is the problem of CRT display. Both Collector supply and step generator seems working OK.

Any help will be highly appreciated.

Best Regards

Eric
