Hi there.  a few years ago i purchased a portable screen w/ built in
speakers for my brother's sony playstation 2.  it worked fine and
everything was good until one day i went to plug it in to the wall and
i hear a loud buzzing emitting from the speakers.  i quickly unplugged

Got a call on this one, can't find anything online. Plug in, turns on,
perfect pix, & sound, after about a minute pix goes black, sound stays,
have to unplug, & start over. Convergence is fine. Ideas? Dani.

Hi Group , I have a Yaesu FT-757GX that has a problem with the
receive frequency attenuating by 500khz. The frequency will jump up
500khz at will and then return to it's selected frequency at any given
moment . It will jump in frequency in all modes and in all meter bands .

Hey guys,
Ive got this LCD screen in a laptop which has this about 1-1/2 inch
thick "lighter bar" running up and down vertically on its screen. The
screen displays the colors that it supose to behind the bar except that

An a/v installer brought this Denon AVR-1804 receiver in to me with the
following complaint. When using the zone2 line out connections, the
volume all of sudden became a fixed line output instead of a variable
line out. You can see the numeric level display change up and down when

I have two remote controls one rca for my Proscan (RCA) 27" tv, and one for
my Panasonic DVD player/recorder.   My DVD player is able to control the
basics of my TV operation too, even will turn on the power to the TV (no
programming required).    But now all of a sudden they both ...

I may post the long story later, but the short story is that I have
a motherboard and a DDR DIMM where pins 3 and 100 on the DIMM and
the corresponding socket are toast.  The gold on the DIMM contacts
is completely gone, and the socket is charred in those positions.

I am using 13" RCA/Thomson TV as a portable and I would like to get
a telescopic antenna which will fit the 3/8" hole in the back of the
cabinet of this tv set. Could you recomend a place I can get one ?

My washing machine makes no noise or anything.  I tested these things.
I checked the power cord with load to where it end in the timer area.
I checked to see if the faucets are on.  It is a machine that will fill
even if the lid is open.  I open the back and the wiring looked clean

I always wondered why I run into people who have some machine or
electronics that seem to last forever.  What was worst that I never had
a story like that nor could I find a particular brand to buy and have a
story one day.  I now figured it out to be a "catch 22" situation.

The set works perfectly except for the volume control.
The volume was turned down to zero using the remote.  When the increase
volume button is pressed on the remote or the button on the set,  the

I have a 120VAC 15A electric motor that is on an aircompressor that I found.
I plugged it in and the motor starts to spin slowly but never gets going
fast then trips the circuit breaker.
It spins eaisly by hand and the bearings seem to be okay. Does it probably

I've got a fairly recent (maybe within ten years or so) Magnavox stereo.
 All that's wrong with it is no panel display.  I have disassembled it,
and ignoring my chagrin at being faced with such a poorly designed item,
it appears that the problem is NOT lamps.

Update..as it warms up after 20 minutes, or so, the unit has tiny specs
throughout the screen, very, very tiny specs, the the right half of the
screen starts to shake from left to
right, it gets so bad the screen gets like it, & it's totally

I am missing the tiny screw that holds a soldering iron tip onto a
soldering iron. Do you have any idea where I might replace this?
Thanks,
