I have a memorex dvd, in my living room, and in my bedroom I have 2 am
radios. If the dvd player is plugged into the outlet(even in standby
mode, switch off) I get a tremendous amount of static on my am
channels. But if I unplug the dvd player static or interefence stops.
How can I correct this problem?

Keep the dvd player unplugged.

Try a REAL DVD player. Most of the Memorex stuff I've seen in the last
ten years is pretty well bottom rung Chinese crap.

How 'bout a power-line filter to stop stuff from going out from the
player? Seems as if a couple of small capacitors (0.01 uf or so) should
do the trick.

Hi,
Even on stand by, the power supply is active which is generation hash
noise being a switching type power supply. Quickest fix is buy ferrite
cores, wrap the power cord around the core(you may need more than one)
to choke off the noise. You can install core(s0 inside the player.
Generally cheap product has a reason to be sheap.

In the old tube-type radio days, 60-cycle hum could be mitigated by simply
turning the plug 180° in the socket. Today, it's tougher, what with
polorized plugs and sockets.

Go to your local Goodwill and buy a new DVD player for ten bucks. (Or
spend a few more at the big-box and buy a new one.) Cheaper than
screwing with filters and such.

Yes, but that was a different problem: here, it's noise, probably
somewhere in the low RF range, being generated by the DVD and
transmitted over the power lines.

As someone else said, ferrite beads in strategic places in the DVD
(maybe just on the power cord) might work, as well as my suggestion of a
couple of filter capacitors.

Of course one can cut off the polarizing wide parts of the plug, or
use a rubber cube tap, which is usually soft enough that one can force
the plug in the wrong way.

Hi,
60Hz hum and hash noise are two different animals. Reversing plug
reversed polarity of the transformer winding minimizing inductive
coupling. Poorly made cheap power supplies have no noise supression or
shielding. For an example, compare mil-spec. vs. commercial grade vs.
consumer grade power supplies.

So he can have two DVD players emitting noise?, LOL!

If you can, try another outlet that's on a different breaker in your
breaker box. An extension cord is good for testing to see which
receptable might or might not work before hauling things around; either
the radio or DVD unit. Assuming the requisite FCC Part 15 or equivalent
is marked on the product, this should work.

You could try re-orienting the radio (its antenna, actually) just in
case it's an RF interference (usually in the intermediate freq area, not
the station freqs). Often moving the antenna 90 degrees will stop that
kind of interference. OTOH sometimes reorienting the DVD player works
too but it's usually easier to move the radio.
If the radio will run on batteries, try that & see what happens. IF
it still get the noise when run by battery, then it's pretty sure to be
an RF thru the air issue rather than ac wiring noise.

Does either the radio or DVD system have a 3-pin plug? If so, is the
3rd wire (earth ground) properly wired in the outlet, AND the 3-pin
prong still completely in tact? e.g. not cut off?
Radio Shack et al has a $10 cheapie plug in detector that will tell
you whether the outlet's hot/neutral are in the right place and that the
earth ground is connected. Output is just reading which of 3 or 4 LEDs
or lites comes on. I think I saw one for $8 last weekend when I was in
for batteries. Cyberguys.com carried them too, last I knew.

If reorienting and choosing a differen outlet on a different breaker
don't make any changes, at least they were easy tests to make. After
those, the interference is most often through the ac power lines. I
just usually check the quick & easy things first, then they're at least
eliminated.

You can buy "line filters" whose purpose is to stop such interference.
Not expensive & often a Radio Shack item. Often works well. There are
a couple different kinds from the ones you just plug into, to ferrite
cores that snap around the power cord. Ferite cores are the easiest to
apply, the plug-in types sometimes a little better at stopping the noise
if made my a quality outfit.

BTW, it doesn't require the DVD have a switching power supply to create
such noise altough most do these days: All it takes is the right diff in
freqs between the source and the receiving point to make static sounding
noises.

I wish I could help you but others have used up any ideas I might
have. You just remind me of my situation. If I am watching channel 11
in analog, either tuned in through the tv, or tuned at the DVDR and
watched on the same TV, and the FM radio is on, on some stations, I
get a whited out picture on the tv. The blacks are grey and the other
colors have low saturation. On other FM stations, the saturation is
good but there are about 20 black stripes down the picture. On other
stations, the picture is fine. The AM stations don't cause problems.

Because it takes several seconds for the relay to close when I turn
the radio on, sometime I leave it on when watching tv to listen to it
during the commercials. Can't do it if it I'm watchinng channel 11
and listening to C-span.

Worse yet, I can't listen to C-span when recording channel 11, or the
picture is washed out.!!

I guess in February this all goes away.
