This was a nice easy fix.

Gorf has been intermittently dropping red, which completely went the other day and would not come back.

I dragged it out today to take some interior pics for dave o and thought I'd take a look at the video.

I started by swapping the red and green input on the connector to the monitor (which comes from the RGB board).

Red was back but green was kinda gone. So I assumed that the monitor was ok. I swapped the red and green back. Red was back but incredibly faint (almost non-existent - just about dark gray).

I tried re-seating connectors and the daughter cards on the monitor, but this didn't change much, I pulled the connectors out of the housing and took a look, they weren't very shiny so I decided to snip and re-crimp some new connectors.

These had a much snugger fit when I re-connected the housing to the monitor daughter card.

Turned the machine on and hey presto red is back with a bang (not literally). Had a quick game just to test it and managed to bag myself 42,730 for my troubles (on jochen's kit)

I have had so many fixes on this machine by just snipping and re-crimping connectors, I've probably done nearly all of them now.

This is a sign that the connections around the one of the delay line tubes is starting to give.

I've repaired a few of these with this issue - it involves micro surgery on the tube.

Ask Steve, I had to micro-repair 3 out of 4 delays on two RGB boards of his as well as trace the board for missing tracks to get all the colours back how they should be.

This is true. He did a splendid job for me and I also now have a working gorf upright.

Keep up the good work guys on fixing these Gorf machines as they are one of the coolest games around.
