    Did you check the fuse in the power cord?

    Do you have a multimeter to verify you have power at the end if the power cord?

    Instruction video on how to identify and replace the protection diode is on my website.

    Its a common diode. If there is a Radio Shack near you; they probably have it. There is a band/stripe on one end of this diode. The replacement diode has to be put in with that band turned/pointed the same way as the one you take out. It is near the power plug area of the radio.

    If you look around you might be able to find an instruction video on how to change it.

    Just replace it if you can unsolder/solder. The part might cost you .99 cents if you over-pay for it. They don't always crumble apart when they are bad.

    Check it with a multi-meter. It should only pass voltage in one direction.
