Re: Tek 465 no display


One step closer! C1549 looked like it might have been replaced with a mylar cap. As soon as I unsoldered one side and turned on the scope, the fan came on! So i replaced it with a 47mf 25 v electrolytic and now had a bit of a trace but way off vertical axis. Good call Albert!

The voltages now are112.5, 55.66, 15.1, 4.9 and -6.4

I see that the vertical axis is associated with the -8 rail and read the troubleshooting for vertical axis anomalies but before I go further I thought I check for advice here first.

Thanks in advance, Russ
