I went over to moms tonight with my CR 70 in hand. I think I figured out the CRT pinout, and it actually seemed like all three guns checked OK for HK shorts. Cutoff and emission seems OK too. Took a few pictures of the set.



What's the little slide switch on the CRT PC board for, possibly setup?




I finally got the set to come on with the CRT board plugged in. This is with no input signal. Normal background hiss with the volume up.


These next three pictures are with a DVD Player hooked to a A/V inputs. I can see a vague image moving around accompanied by a loud hissing-scratching- popping sound from the speakers, with the volume all the way down. It almost seems like the video is modulating the audio power supply. Anyone recognize these symptoms? This is not what I remember this set doing 12 years ago when I had it on. But my folks had two of these same sets(one upstairs, one down), so it's possible I was working with the other one at the time.






I'm about to drag this set up out of moms basement and back to my place. It's a real pain trouble shooting it over there away from my shop. If nothing else it needs to come out of there so I can dispose of it. But it sure would be nice to get to the bottom of this problem before sending if off to the recyclers.
