DFE Communications Corp. make a device they call "single line
phone-to-phone intercom system" called TNT-8000. They do not have a Web
page, believe you or not, so you'll have to call them at 800-822-4TNT to
find out more. Basically, this device makes it possible to share a single
line that is expected to be paralleled between all the phones in the
house, the traditional way phone wiring has been done residentially.
If you ask me though, I'd say that the best way would be to get a hold of
an inexpensive KSU or PBX phone system like another poster suggested here.
You will have to re-wire the house so every phone has a separate cable
coming to the phone switch location, but in the long run I think it is
well worth it.

There's usually a number the telco techs call to get a callback on the
same line you're calling from.
It used to be your own number, dial it, then after 1 blip, hang up and
then the phone rings back. ( Telus has downgraded their system , so
that doesn't work here in BC anymore :-( )
Might try to get in touch with your local telco tech & get the
callback number from him ( $0.00 intercom) ;-)

Sorry, I also should have said that with this callback method, that
when the phone rings back, keep waiting on your phone until the
ringing stops (means someone in the house has picked up another
extension) then pick up your phone again.
I dunno how clear that is..but it used to work for me.

Radio Shack used to sell an intercom system that used the AC wiring for
TX/RX. Worked well. Some other maker may make one. Much easier than
rewiring the phones.

ignore me just like customers specially when I call them at their

a day to two for a friggin part!.
When did these products change from entertainment to life support?
Been doing this for over 40+ years and really sucks the lack of respect we
get from our employers, let alone the flippin customers. They can't even
remember what serviceable position, out of an entertainment centre, or wiped
clean of filth mean!!
We are out there trying to service the products to the best of our
technicial ability. With the lack of support from many of the manufacturers.
Let alone the fact that the service litertature costs the average shop about
15% of their budget.

Buy one of the newer multi-handset cordless phone systems. I know the
Panasonics let you call from the base or any handset to any other
handset. The sell some models with three to five handset capability,
but most come with only two handsets and you must buy the additional
units seperately.
I use this in my home as a one-line telephone, and three-station
intercom ( base plus two handsets )

I don't know your wife, and I don't mean this to be a put-down. But the
power of suggestion is very strong for some people. In other words, at
this point, she may get a headache when she gets into this car simply
because she EXPECTS to get a headache when she gets into this car. This
cause is especially indicated if the headache comes on nearly instantly,
as you have described - so soon that none of the causes being discussed
here (exhaust fumes, neck position, lighting, EMI, etc) have had a
chance to kick in yet.

I knew a girl like this once, but her particular hot button was food
that had sat out on the counter for more than two hours. She was
convinced that any kind of food would spoil in that time, and that she
would get sick if she ate it. And since she expected to get sick, she
did. And she was truly miserable - she wasn't making it up. She would
retch and gag and vomit almost instantly if she thought there was even a
possibility that the food was "old", even if a dozen other people were
happily munching on the same thing.

Hehe that reminds me of a friend I had who would ask how old everything in
the fridge was and wouldn't eat it if it was at or past the Sell By date. I
finally started rubbing off the date (only sell by, not use by!) and lying
about how old it was so he wouldn't complain.

 

[glieberman]

Didn't see any mention of this so I thought I'd throw it out for your
consideration:

You may want to try having your wife wear a good dust mask over her
mouth and nose to filter the air she is breathing. If the headaches
disappear or diminish significantly, then at least you will have good
idea that the problem is air-borne (like mold) and you will have a
better idea of what may be going on. Also, as weird as it may look, at
least if you and your wife need to go somewhere in that car, you will
have a way to do it (if it works).

In the absence of air-borne problems, your wife may be very sensitive
to and be reacting to a very high frequency or very low frequency sound
coming from somewhere that is causing her headaches (my wife is an
audiologist and suggested that idea). Women, especially, are sensitive
to and can hear very high frequencies that men cannot hear, especially
as men age. Sounds like that may be originating from some metal part
wearing out (break shoes, bearings, etc.) or even a window that isn't
closing all the way, causing some road noise.

Best of luck.

Thanks for the info as I couln't find who makes these tvs;
I will follow up for a schematic with DSE but in the meantime I would
like to know if the voltage at the collector of the HOT for these
portable 12v tvs in general should be 110-130 as the bigger ones. (I
have measured 10.84 volts which is coming straight from the FBT.
Thanks A.T.

SNIP

Some time back there were a number of different branded small 12v TVs using
the same chassis. I cant recall how big they were exactly but around 6-8".
The entire TV ran on 10V, when using the 12VDC supply it first passed
through a 10V linear regulator, when using on 240VAC just used a 12V
transformer then through the same reg. The most unreliable part of them was
the regulator and a switchmode equivlent of the genuine encapsulated part
used to be available from GB telespares. That said I do recall one time
having one of these chassis fail to fire up the horizontal and it did turn
out to be the jungle / sync IC.

Hi,

When you say you changed the cd, do you mean that you put a different Sat
Nav cd in. The reason being it may have uploaded some software and possibly
not completed properly. Problem then arises that the older (original) cd
then won't read either. This is certainly the case with Navtech, (not sure
what yours is) as if you upgrade to a later year then all earlier years
apparently don't work anymore.

I'm sure someone will correct me if this isn't the case.
Other than that, as you suspect, it's probably the unit that's bust.

Good luck
Bob

Hi,

Car: Audi A8 2.8 1998 model (UK) S-Reg.

My Sat-Nav system seems to be bust. It was working fine but after I
changed the CD it no longer works, even if I switch back to the
original CD

My guess is that the drive was close to bust due to excessive wear/dust
or whatever, and changing the CD just worsened the probelm beyond
workability. I have been looking for a replacement unit at breakers but
to no avail.

The error message in the display is invariably: "System error: Please
check CD-ROM".

I tried using one of those CD-ROM cleaning CD's with tiny brushes, but
that didn't make any difference.

Now I'm wondering what the most common type of fault in this sort of
unit is, and if a hobby guy like me stands a chance of repairing it
myself. I read the faq at http://www.deinmeister.de/cdrep_e.htm and
browsed http://repairfaq.ece.drexel.edu/sam/cdfaq.htm as well, but I'd
like to know what my odds are before I start trying to take the unit
apart.

Also the unit is mounted in the boot (trunk) of the car and the surface
of it shows some signs of corrosion which would indicate it has been
exposed to humidity (not surprising). So I wonder maybe some corrosion
on the rails where the head move might prevent it from moving correctly
and I guess that could be fixed with some graphite or teflon oil.

Basically I'm just hoping someone has some experience with a unit
mounted in a car over a number of years in a medium to cold climate,
and can give me some idea of what to expect and whether it's worth it
for me to try and repair it myself - otherwise pointers to someone who
might be able to help, either with repairing the unit or sourcing a
replacement, would also be greatly appreciated

BR,
Descore

Causes will vary depending upon type of volume control - motor-driven analog
potentiometer, totally electronic using volume control IC's, you can see
they would be different.

Bad solder connection somewhere or a momentarily stuck front panel or remote
control button are the first things that come to my mind. You probably will
just have to wait to see if it recurs or becomes more frequent before any
real troubleshooting can begin.

They also sell (sold) one which uses the phone line to carry the RF from one
station to another...a little more reliable than the ones which inject RF
into the power line. Those get stymied by being plugged into outlets which
are on another phase of the AC network in ones house.

I've actually converted some of the power line ones to work on the phone
line...pretty easy to do. I find them all the time at thrift shops for next
to nothing. They always seem to work fine.

thanks,

RH34 is 1.2 ohms 2 watts. It should be a fusable type film resistor.

It connects the 80 volt supply to RH41 (1 ohm 5 watts) the other
side of which goes to transformer LH01 which is driven by QH22 through
RH42 (.15 ohm 1 watt) to ground. Something to do with horizontal
centering or linearity or something.

Definitely check the zener diode ZDB01 near the vertical chip ICB02
like James says. If its open in the forward direction then the main
power supply is overvoltaging and you must replace the 4n35 (ICA04).
And check RB30 and RB35, both 1 ohm 2 watt resistors in the vertical
section. If the zener was bad its likely ICB02 is bad also.
