Hi, I've just been having a go at fixing an old Acorn AKF40 monitor (a
few months shy of ten years old I'm afraid), which makes a screeching
sound and fails to provide any display when powered up. Not having done
anything like this before (I generally stick to low voltage digital
stuff) I could do with a little advice.
I checked for bad connections and dry joints first, then started going
around with a multimeter looking for open resistors, shorted caps etc. I
soon located a fault- a power resistor with a discoloured area on it
which is completely open circuit. It's located somewhere in the switch
mode power supply. What do you think this resistor is likely to be for,
and is its failure consistent with the symptoms I'm seeing, or should I
be looking for other failed parts too? Also, it says on it:
4.7 [ohm symbol] K 7W
Would I be right in thinking that that means 4K7 rated to 7W?

If it doesn't work, you're not hitting it with a big enough hammer
