Hello,
I am a proud owner of a 420se 1986. My habitat is maastricht in the Netherlands. I married and have 3 children.
I tried to repair my cc with coding part 0055450732. I replaced the capacitors 2x 2,2uf, 2x10uf, 2x22uf and all MKT, one chip LM2901N.
I soldered all contacts. I checked de transisters PNP NPN. The transistors with heatsink are new. And a new cristal.
It gives no reponse sadly,

Much regards Rob Deckers
