Hi;
I rebuilt a WG6100 HV cage, all recommended components replaced (FAQs) as well as some transistors and resistors. Problem is that the B+ is 196v and even thought the "screen" is turned all the way down, the display comes up bright, washed out and I dare not leave it on for more than a second or so without fear of burning the CRT.
I checked good but replaced anyway, Q901, 902, 903 and ZD902; swapped a working Q900; replaced the "555" and still the 196v......
Tested R903, 904, 905, 906 and 907 - all good.
I did not pull but compared all replaced capacitors (with an ohm meter) to a pulled working HV cage and they were all basically the same.
I have spent several HOURS on this and am coming to my wits end.
Can anyone help?
Thanks in advance
Jeff
