Hey all,
I've got an oddball Orion PBW 2018 in my WWF Superstars cab. For a while it's been running good other than some minor interference of some kind on the screen. Recently the picture lost blue and I pulled the chassis and did the usual dance of touching up solder anywhere I could see possible problems and especially any video headers and adjustment pots. I also tried to hook it up to my rejuvenator, but I wasn't even able to get the heater to fire up. I should note I just made a universal adapter today from some Rat Shack mini-clip jumpers, but I triple checked all the connections. I'm wondering if the wire on those is just too small to handle any kind of voltage. Anyway, after that I put the monitor on the bench and went over it again. I fired it up and then I had a horribly blue picture like what you see here. It went away and now it's come back again so I put the monitor back in the cab and called it a day. I've never seen a schematic for this thing so hopefully someone here can offer some advice. I'm thinking maybe I will change out all the pots since a few of them seem are really tough to turn. The blue pots don't seem to be having any effect. I may end up just getting a chassis for a spare K7000 tube I have and running that in there, but maybe I can get this thing going. Here's the fugly pic I'm getting on this thing right now. Notice how blue it is and the wrestling ring should be a blue shade but it's green! It's like the blue is only on the outside area of the image
Edit: Forgot to mentioned that I've already pulled and tested both blue color transistors on the neckboard.
