i bought a MC28M6055CW/EU microwave a few years ago which starters to behave a bit weird after about a year. Several buttons wouldn't work or you'd have to press stand combinations. It grew slowly worse over another year and it had now completely stopped working. I was previously advised to clean around the buttons which seemed to work a little, but possibly only because I'd turned it off and on again. I know this is not representation of Samsung quality but also that several other owners of the same unit face the same problem. No doubt it only needs a replacement PCB but i can't find one. Could you supply one, please
