High pitched squeal thru all spkrs when input to unit from vidieo 1and 2

The sound quality when i play a cd or a dvd is excellent.However,when I switch to the FM radio function there is a high pitched squeal along with the radio.In addition to this,and most frustrating,is when i switch to video one or vidieo 2 to watch HBO,cinemax ,or XM radio thru THRU DIRECT TV,I also get the annoying squeal
I have also had all the other dvd/cd ejection/standby problems with this unit when new.Thank god I bought an extended warranty and after being in the shop at least 6 times these problems were corrected
Now it is in a shop again(for over two weeks) and the tech still hasn't found the squeal problem.PLEASE HELP!!!!

    I am having the exact same problem... Our DAV-FC7 has had no problems until recently when it started having a high-pitched squeal on FM and TV Tuner whenever I turn the machine off, then on again. Eventually, it fades (in about 30 minutes to an hour) and I can hear again. But once it is turned off, the squeal occurs again when turned on.

    I have checked all connections, cables, and proximity to tv, other devices...to no avail. No idea what's causing it, and warranty just ended as well... of course!

I have the same problem, the solution looks like it is to replace a capacitor on the main board.

Given its age, this unit needs a little TLC. Units of that vintage used some capacitors that may have dried out a bit and need to be replaced. There are also op-amp ICs internally that may be defective. I would suggest a visit to a service shop that works on keyboards as not all do.

Keep us posted.

Humming noise


If this is like my unit it is a high pitched squeal. I received my unit as a gift for Christmas 2007 and I thought it was defective. I contacted Homedics and they sent me a replacement but the problem persisted. As licensed amateur radio operator I am versed in electronics so I decided to track down the source of the noise. It turns out that the 16VDC power adapter is the source of the noise. It is what is called a "switching power supply" and is unfortunately not well filtered causing the high pitched squeal. I was able to get rid of the noise by modifying the power adapter and adding a 2200 microfarad capacitor in parallel with the output. This filters out the high frequency ripple and gets rid of the squeal. An alternative solution would be to search the Internet for a better 16VDC power adapter. It must supply 2 amps of power and have a 5.5mm OD/2.1mm ID center positive power connector.
