I recently purchased a Road Show and I'm slowly fixing some problems. I'm pretty new to the hobby and I've hit a snag. The one problem I can't solve is the entire row 7 of my lights is out.
So far I checked/replaced all bulbs and used a multimeter to test continuity on the string of lights, which narrowed it down to a problem with the power driver board. I confirmed the problem is on the board by borrowing a replacement power driver board. With the borrowed board in, the lights work fine. My buddy who is helping me had a spare transistor, so we replaced Q84 as a shot in the dark. That did not work, so now I'm not sure what steps to take to continue trouble shooting. Any help is appreciated.
