MS9 no red?

Hi guys, trying to diagnose an issue with my MS9. Basically it takes about 10 minutes for red to show up after the cab is turned on? I am guessing something needs replacing, just. It sure what I should be looking for?

for the red to appear after some time would point towards bad connection, possibly bad solder joint on neck crt socket
also you need to prove whether its red signal missing or chassis at fault
you should check the rgb cable from the jamma to chassis and then check the neck card for bad solder joints, also check remote board connections, red gain pot and solder joints both ends

Thanks Grant. This did start to happen after I was fiddling around with the pots directly on the chassis making some adjustments so maybe check solder joint on that pot first?
