This was a interesting repair. I was going to go strait for board replacement until i had seen the cost of a second hand board which was really expensive. I had checked the board for known common problems and everything was normal voltages wise but board was dead. So i left it until i had no distractions and pulled up some circuit diagrams. Took me awhile to finf it but it was worth it in the end. Customer was happy that it didn’t cost her too much.
