I exchanged all of that…but nope. that was not it.
when I look at the pcb, i see around k4:
q6 and d9 which directly seem to have a function to provide the 12V for the k4 to work, no ?
not sure what the relais next to k4 does…
but that has well q4, q5, d8
I exchanged that relais as well just to be sure…
So, i guess exchanging those transistors/regs/diodes is the next step if you can provide the part number.
