Mike,
The display flicker might be due to the on-screen readouts stealing the beam at times.
Does the flicker go away if you turn the readouts off?

Hi All
Have two issues with my Tek 2246 scope display. Looking for common faults
before digging in.
1) Display brightness fades after approx half hour after power on. Display
geometry is fine, it just dims
2) Display seems to have a slight flicker . . . it's also noticeable on the
green LED's illuminating buttons
Bought it in not working condition. Replaced rectifier in -15VDC supply. All
now working well except these two issues.
All other supply voltages look steady, although have not taken time to look at
any ripple/abnormalities.
Thanks in advance,
Mike
