We got a unit that has an issue with lamp . Basically it shows lamp intensity alarm and lamp voltage alarm.even though , we’ve replaced the PUVF complete bench and the problem was still remains . Lamp Voltage reaches 1340 and the lamp intensity reads zero. Then , we’ve replaced PCB, Flasher supply board , PCB, power supply board , PCB CPU and PCB mother board.unfortunately, it doesn’t work ! We go through the user manual and tried all the ways that recommended in the troubleshooting part of it but that didn’t work. What can be the possible cause of the lamp intensity to read zero ?
