    Axial Resistors help

    Hello all hope you all well
    I just want to make sure I got this right.

    This is 150 Ohms 5% Axial Resistors
    Brown Green Brown Gold
    Please let me know.
    Many Thanks

    To me it looks like 180 ohms, I can't see any green but LED lighting does mess up colours.
    I don't see a use for such a low value resistor on the SMPS primary, where that part is. Usually a resistor like that is a bleeder or snubber or startup resistor and much higher value.
    What does the part connect to? pin 8?
    TOP242GN looks odd in your pic, there is no pin 6 but you have pins and a blob of solder there, and 6-7 tied together does not match the datasheet.

        OK what is this different board pic? You have Rev. 001 or 002? Eek board is going for $700 on eBay OUCH.

        What's wrong with the resistor R46, what does it measure?

        In many other pics it looks like 180 ohms but if you think it's a green verses gray stripe then maybe ask someone else for an opinion. Size is 2-3W and I would use a fusible, flameproof resistor there.
        Not clear what it is powering. I would carefully trace out it's connections, after discharging the big high voltage cap. The DC SMPS does not need it so it must be for something else, maybe a valve.
        C29 10uF 50V is a critical part for the DC power supply, if it's misbehaving. For the TOP222GN
