All of a sudden all of Row 6 and Column 6 are out. Bulbs are good.
Reseated J134 & J135. Also Reseated J138. No good.
Pin starts and plays fine but having 15 lights not working isn't fun.
Anything I can check?
I have checked wires going into the connectors, all good.
I tried to check Q85 & Q93 on the driver board after pulling off J134, J135 and J138.
Does the black lead go in the top of the transisitor heat sink hole or the red probe in MM diode test mode?
Should I test Q85 and Q93 the same way? Did I pull off enough connectors to test the transistors properly?
