Re: My 475


Correct no image on the crt or even using the beam find. But all the other switching(lights) on the face panel work. I'm trying to figure it out, and I love all the input and help from you guys. I been out of the electronics game forever, but I'm smarter than the average bear. The tektronix troubleshooting manual, stated about injecting a - 10-15V for about 10" using the EXT z input, thats my next step. By the way is a pretty cool manual, very clear and step by step still lots of scope lingo but I'll keep at it.
