There's a polyfuse in series with the power supply to the tuner that can go open circuit or high value. It is mounted close to the tuner & is yellow/orange colour. It looks like a disc capacitor. It might have something like M60 065 or W60 065 (or something similar) printed on it.

You can see if this is causing the problem by temporarily shorting it out by twisting the leads together.
