If there is NO audio and no xmitt, then it is most likely something common to both circuits? Anyway it's not really possible to diagnose a fault, via a forum, unless clear cut, which this is not, your best course of action is to work through the troubleshooting steps and see if you can isolate your issue.
If DIY isn't able to be done, then the best bet is to contact a Yeasu local or head office, or over the 'net, and ask for a referral to an authorised serve center, here ask for a "Quote" as to costings and type of repair, this way then at least you can make an informed decision,as to what to do.

SOURCE: No dash lights, power locks don't work, fuel

all these circuits share some common fuses, check fuse #6 ( 10 amp ), fuse # 11 ( 15 amp ) & fuse #12 ( 10 amp ) all in the inside fuse box at the left end of the dash.....good luck

Yesterday my wife had the car battery replaced by the RAC and her Pioneer DEH-2050MPG unit doesn't work now and gets no power to it. I checked the car fuse for the radio and it appears to be okay

Check all of your fuses. There are probably two fuse boxes in the vehicle. There may be a fuse either inline or on the back of the radio.

Radio doesn't work 2013 sorento just went out 1200 miles

We experienced an intermittent problem where the entire audio system on our new 2013 Kia Sorento would fail to turn on at all after a brief stop (at a thruway rest area) on a long trip. When it happened twice the dealer replaced the entire unit and we had been trouble free for almost a year when my daughter reported something flaky happening to the radio recently again. I am keeping me eyes on this problem once again.

Doesn't power up

Check the speaker wires for shorts, if okay! the audio output stage is shorted, all affected parts will need to be replaced.

Anyone have the code to reset this radio. battery went dead now the radio will not come on ?

Try checking your fuses. If the radio doesn't come on a code is not going to do any good. As far as I know these radios don't require codes anyway.

Yeasu ft840 overload +12v,readout still good

You can replace your audio and receive transistors with a new one or a compatible one and be back on the road again. the transistors are available from all ham dealers and are normally not too expensive.
do not try to fix something that ain't broke. if it is working, leave it.
