Change your Home Station in the DAB settings. If you do that and it reverts back, there _may_ be a motherboard battery that needs replacing. It is losing its memory when it is turned off. https://www.manualslib.com/manual/1366367/Jvc-Ux-D150.html ..

First, contact Bell and inquire whether their remote control contains the appropriate code.

Find the components that failed and replace them.

1. Open internal fuse 2. Open power switch 3. Power supply failure

Clearly there is a short circuit somewhere in the circuit after the fuse. A close examination of the circuit and components might reveal evidence of the location of the short but if not it will mean disconnecting things one at a time until the short circuit disappears.

In my experience the JVC brand hasn't maintained it's early promise of quality and I avoid the brand these days. It would have been helpful if you described the noise and mentioned whether it was constant on both FM and AM. Excessive noise isn't unusual on AM due to the inability of the basic circuitry to reject the various sources of interference found in the average home, partly because the AM ferrite rod antenna is usually inside the radio. The average AM radio is highly receptive to receiving and amplifying lots of interference from many sources especially that radiated by fluorescent lighting, cfl bulbs and even nearby mains wiring resulting in a loud hum or buzz. With the high popularity of FM and the introduction of DAB that has increasing popularity, the development of AM receivers ceased several decades ago. FM is immune from that type of interference but is by no means able to reject all interference and a powerful signal from an external antenna produces the best result, the best signal to noise ratio. Assuming the radio isn't faulty, the problem is most likely interference. If the power cord has a ground conductor it is very important it is connected to a good electrically quiet ground. If this isn't possible it could improve things to use an independent ground to the outer conductor of the coax cable to the FM antenna.

I searched jvc.com for your model CA-C77BK S/N and couldn't find it even in the archives.

It must be a discontinued unit.

Usually when this happens you have to take the unit apart to retrieve the cd.

I don't think it's worth fixing, as parts don't seem to be available or listed, not even the user's manual online at jvc.com.

However, I did find a link for the service manual for this vintage compact component system:
http://www.vintagemanuals.com/manual.php?manufacturer=JVC&model=CA-C77BK%2C+CA-C99

May I refer you to that manual to try to figure out how to fix this problem.

Unfortunately, it costs $33 for the manual. You'll have to decide if it is worth it to buy it.

Good luck to you in fixing this problem.

Hi hope this helps. ....cheers
