    Hi guys thanks in advance...

    Trying to repair this... glad if I can get some help or comments.

    The Power side for the fan seems to be working. But the bulb does not light up. Tested the end of the bulb output but I don't get much readings. Pictures attached.

    Thanks ahead!

    Welcome to ETO!

    Because it has quite a low component count, you might be best to just test everything with a multimeter. Anything that seems odd we can investigate further. It would be useful to know where all the wires are connected!
    I'd start by testing the rectifiers. Also check the relay is clicking AND making contact when it's supposed to.

    Hi S

    Before you get into too many detailed checks, I'd have a close look at the integrity of some of the solder joints. The pictures are not great but some of them look a bit iffy to me .. .. .. pcb 1.jpg

    You might have a simple fix .. .. well, you can always hope ! :)
