Look at pages 16 to 20 in the user manual. This may give you some insight as to haw this may occur. Also, A google search for this radio brings up a lot of useful info. This is a complicated radio as is indicated by the 80 page user manual. It's not one that you can pick up and use right out of the box!

The link below should help you. Lots of info in the service manual. It's intended to let someone rebuild the radio from the ground up.

Try using an external speaker and see if you have the correct volume level. Radio speakers fail often, especially when used at high volume. The simple fix is to replace the speaker. It is seldom for the audio amplifier to fail this way. Usually they work or they don't.

Here's a link to the service manual - www.shercoares.org > doc_files > manuals > ica110_sm. This may help. Have you checked both fuses? They should both be about 10A. Use a meter to check them. A visible check may not show the fuses open.

I have an icom 91 and still haven't figured it out.
It is easier to use an app and computer and more intuitive.

You need to be a very good technical person with electronics to work on these. The issue is most likely a PLL board issue. You need to be able to troubleshoot to the component level. The service manual appears to be https://www.manualslib.com/manual/738448/Icom-Ic-706mkiig.html
