Cheers Allan July 13, 2019 at 9:57 am #462446 electrofixModerator don’t know but switch was removed on later models so whatever it does Beko decided it was not necessary cant see it switching off the display have you got a no power problem on the board ?

July 13, 2019 at 5:12 pm #462448 electrofixModerator cant see it being the switch and anyway you could check the switch for continuity whats the power supply on the board transformer or switch mode chip if its switch mode look for the fusible resistor and see if its blown. normally 40 to 80 ohms or so Dave July 13, 2019 at 7:06 pm #462449 allanParticipant Thanks Dave will do Author Posts Viewing 5 posts - 1 through 5 (of 5 total) You must be logged in to reply to this topic.
