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
