I am having an issue with my BK, and lamp column 2, pin 9. The column 2 lamps remain on fast flickering, but never go dark. I moved other lamp columns to this pin for troubleshooting purposes, and those lamps were affected as well. Definitely has something to do with 2J5 pin 9.

Also the resistor R150 is extremely hot compared to the other adjacent resistors. Even the old resistor that I replaced showed signs of overheating too. So this must be a symptom of the issue.

I have already replaced all of the resistors R148 - R156, but even the new R150 resistor is showing visual effects of being too hot.

Any idea whats going on here? Last problem to fix on here, and the resto is done.

Along with R150. It appears that Q65 is getting very hot as well. Ive got big faith in you guys. Bet its a single component.

Thanks
Bill
