Hi ,i have a problem with this unit ,i suspect it is outdoor pcb .Is there some component that could the problem and it is replacable ? The whole pcb is expensive and would be better to buy a new unit .I have checked few resistors and capacitors on the com terminal 3 but couldnt find anything wrong .I hear a lot of this units have this problem .
In one machine like this a had a problem with power module on outdoor pcb and manage to repair it .Maybe someone has a solution?
