12volt supply on manhattan

[johna]

i have accidently blown the 12volt supply to the remote switch on my manhattan 350. anybody got an idear how to fix it.there is no fuse, so must be electronic.

Locate a circuit, make it available and I will attempt to nominate the component(s) (likely culprits) - I would expect to find a low-value fusible resistor open-circuit.

if i had the circuit diagram i could follow it back but the resistors are so small its realy hard to follow.and very hard to lift the resistors to check them but i will have a good look at it on the weekend.thanks you ocean i can now narrow it down to a resistor.

I would be looking for a grey colored resistor in probably 1/2 Watt size.

These are usually mounted 10mm or so above the PCB to prevent damage and allow some air cooling. I would look around the power supply section, measuring all the low-value resistors - a safety (sometimes termed "idiot" !) resistor is usually easy to spot.

HINT : - unplug the receiver from the mains. :D
