Hey everyone. I know it has been awhile, but I've been taking all the suggestions and continuing to work on it and have finally got it working and looking good!
For starters, thanks a ton
@YerpS3s for the Sharp Image referral. After taking everyone's guidance and troubleshooting as many things as I could I had to seek additional help. The lack of any documentation on this chassis really limited my ability to troubleshoot much beyond the usual suspects. I reached a point that I thought I was at risk of doing more harm than good so I reached out to Sharp Image and they took on the project. When they got it they discovered that whoever recapped the chassis previously had installed a few out of spec caps. So they swapped those out and also reflowed the board. Definitely would recommend Elvis at Sharp Image for anyone needing chassis help!
Once I got the chassis back I hooked it all back up and unfortunately it didn't immediately work... Sharp Image had sent me a video of the chassis working before returning it to me so I started to troubleshoot more things on my end. I checked my PSU, step-down converter, connectors and everything checked out. I was starting to lose hope but then decided to watch the videos from Sharp Image to see if I could spot any differences, as a last ditch effort, and noticed that they had things connected differently than I did…
I always take pics of things before I disassemble them so that I can reference it and put it back together. I went and checked those pictures and I had things connected like my original pictures. Throwing caution to the wind I then hooked things up how they were in the videos and then it worked! So obviously someone had messed with this before and then hooked it back up wrong. I had no way to really know this because I didn’t have documentation to say otherwise. Quite ridiculous, but I guess par for the course considering that some of the caps were out of spec.
Anyways once it was fired up I degaussed the screen, adjusted the G2 pot on the flyback (it had been moved from the factory position and the screen was extremely dim), dialed in the the geometry, and it looks fantastic now!
Again thanks everyone for the help along the way! I know this is not a common chassis with very little information available, but if anyone else comes across one and needs some help getting it back in tip-top shape feel free to reach out and I'll be happy to provide whatever insights I can. I'm no expert, but I've taken this chassis apart several times now and fiddle with most parts of it.
