Toshiba TV29C90 problem; Image fades to black...

The receivers cost $45 plus shipping. Not excessive. Might be a way
to go. A spare receiver
would be a sure go/nogo test for the alignment too.

Not connecting anything to channel 1, doesn't mean voltage = 0V, it is
"in the air" so, any voltage may be there. Try shortcircuiting the
channel, and see if the same problem appears...

Looks like we're making progress -- thanks to that real nice feller who
posted and suggested I try using the camera with an AC adapter.

[Note to the "try a new battery" crowd: No, it wasn't the batteries.]

I picked up an adapter at Frys Electronics for $19.99. I saw some on ebay
and elsewhere online cheaper, but by the time you add the $5-10 "shipping
and handling" and wonder what kind of adapter you're "really" going to get
and when.... I thought this one was the best choice. And it's a universal
job - all kinds of voltages, and current up to 2500 mA, so that's fine for
the C700 and my other junk too.

First I tried the camera as is - that is on good (new) alkaline batteries
only - to be sure that it was giving the same problem. Sure enough, same
problem - one shot or moving the zoom lever and "battery bad" message pops
up.

Then I plugged the AC adapter into it and first time every time, the
camera
works again, just like it's supposed to, time after time, zoom in, zoom
out,
click, click, click, click, click....

Then I removed the AC adapter and used it with the same batteries only
again
and it worked every time, zooms in/out, etc. just fine and no battery bad
message.

Someone also said that there might be charging problem -- might be it.
May
be still a partially open circuit, bad solder joint or failing component
somewhere between the batteries and the power circuit. AC adapter may have
temporarily charged up capacitors enough to get a few shots from the
battery-only.

Time will tell -- will see how many photos I get out of a new set of
batteries and report back.

Thanks again to all for all the dozen of constructive help! It took
several months, but saved me $155 in repair charges and I gain a great
deal
of knowledge about how these things work.

And a special thanks to all the whiners, complainers, know-it-alls and the
"just buy another one" boys. Without your endless jabs and ignorant
comments, I probably would've dropped this months ago! B^)

Hello

For anyone who has burned CD's for Music, or Data, I've found
VERBATIM
CD'S are the worst.

That's strange. I have been using them for years CDs and DVDs and have
never had a problem with even one. As a matter of fact they are my
choice brand.

I thought I had a problem with my CD-RW Drive, so I
cleaned the optical laser with a cleaning CD,

You might as well sacrifice a goat or wave turkey feathers over it. I
checked with my PC users group and nobody has ever had any success with
one of these.

It appears that the stamped out( bright silver
surface type) CD's from the Software Companies work the best.

That's because these program CDs are not burned on a Drive like you
find in a PC. They are made by pressing the film against a glass
master before bonding the different layers together. This is the only
way to make thousands of copies at a reasonalble cost and they are much
more accurate. I one visited a place where they made video disk and
the machine they made the glass master on was mounted on a block of
concrete 20' square separate from the building and it's foundation to
prevent vibration. Compare the surface of one you burned to a program
disk. You can see where your drive stopped burning. Remember it burns
from the hole outward.

These VERBATIM CD-R's,
the surface refectivity is very low, so the laser takes longer for it
to read the CD.

I hope you were not using a Mk-1 eyeball to measure this reflectivity
unless you can see infa-red.

I'm thinking of dumping these CD-R's and
buying some others to replace them.

Don't dump them. Take them back to the place you bought them. I
needed a large quantity of DVD's to make copies of family reunion
movies I made back in the 1950's for all the relatives. I bought a
stack of 50 of a brand I had never heard of from MicroCenter that was
on sale. When I tried the first 4 DVD's three of them gave errors
during the burning process. This was the only brand I ever had a
problem with so I took them back to MicroCenter and got a refund after
filling out a form. I bought a stack of Verbatims and made my DVD's.

A few weeks later I received a letter from the MicroCenter Vice
President of International Product Sourcing Group. It contained a
letter apologizing for my trouble and 2 DVDs they wanted me to try.
They wanted me to see if there was an update for the Eprom and firmware
of my burner and install it before trying the new DVD's. I checked the
support site for my drive and sure enough there was an update. There
was also a forum with several complaints about the new update turning
their drive into a vegatable. I downloaded the new code but decided
not to install it until the problem is resolved.

I then tried to burn one of the new DVDs they sent me and it got a
"Session Fixation Error while writing lead out". The DVD would play
all the way to the end but did not return to the main menu.

Like you I have only had a problem with one brand.

The specific client I am trying to replace does identify itself as VT440,
which may be amusing to some. VT440 is obviously not as common as VT420 or
VT220. Whether that's right or wrong or common or rare, so what.

The section DEC Terminals at a Glance in "DEC Video Terminals" seems to
indicate that VTx40 terminals can display ReGIS and sixel graphics.

http://www.cs.utk.edu/~shuford/terminal/dec.html

Part of the confusion is my fault. For quite some time, the
"DEC Terminals" page at that URL has contained the following text:

"The next generation consisted of the VT320, VT330, and VT340,
while a further generation comprised the VT420 and VT440."

Today I have changed it to omit the reference to the VT440 and have
put a small note to correct the false impression.

Among my collected terminal documents is one prepared by DEC as an
internal specification of the VT510 model, which consists largely of
a kind of checklist of DEC terminal models and features implemented
in each one. Encoded in Postscript, this file resides here:

http://www.cs.utk.edu/~shuford/terminal/dec_term_function_checklist.ps

While it contains entries for many DEC terminal types, including VT100,
VT220, VT320, VT340, VT420, and the VT510, it contains no reference to
anything called "VT440".

An educated guess on what happened: it is likely that, when the VT420
was being specified and positioned to replace the text-only VT320, DEC
decided that the design effort necessary to make a replacement for the
graphics-capable VT340 was too great, given the market projections for
sales of this hypothetical "VT440". So the existing VT340 model was
retained in the catalog and sold alongside the VT420 until the VT525
took over as the graphics product. Peter Sichel might know the whole
story, but he doesn't seem to read this newsgroup much anymore.

(The VT330 was an interesting beast: if I recall correctly, it could
display only text, but it could connect to two separate sessions at
the same time, displaying one on the top of the screen and one on the
bottom. There were two serial ports, but the device could also obey
the patented "Terminal Device Session Management Protocol" to multiplex
two sessions on one wire. Apparently the VT420 also implemented TDSMP,
but the control sequences never appeared in the product documentation.)

As to terminal emulators that can do graphics: I have never seen a
freely available package capable of ReGIS. A few of the commercial
products can/could do it, such as WRQ Reflection, SmarTerm 340, Rumba,
DCS EM340, poly-STAR/GW, and KEAterm:

http://www.cs.utk.edu/~shuford/terminal/regis_emulators_news.txt

The old MS-DOS Kermit by Joe Doupnik can do the more bit-map-like
Sixel graphics, but (to my knowledge) Kermit-95 cannot. (But perhaps
Frank will comment...)

I am curious to know, with the brand that you had a problem with, did you
try burning the disks at a slower burn to see if they were still not working
right. I found that the slower I burn these, the more reliable they are,
especially in standard home entertainment players. Computer CD drives are
less critical to play disks that were burned in other drives.

I myself have been using Verbatim disks for years. I like them more than
most of the others that I have tried. I like to burn all my disks at slow
speed. I found that when ripping most disks at 52X, I have had more
problems. I will generally use about 4X or 8X at the minimum, and sometimes
I will burn them at about 12X to 16X.

As for upgrading the firmware in your burner, I would not do it, unless
there is a need for it. I found that if something like that is working well,
and did not show any problems, it is best to leave it alone.

Sometimes they come up with upgrades to firmware in these devices, because
something new comes out where there is a problem. If you never start using
whatever is new that is of concern, you will probably never have the problem
to begin with.

A number of years ago when DVD writers first came out, a client of mine
decided for some reason that his new DVD writer needed an upgrade, because
he read some thing on some newsgroup somewhere. He then logs on to that
manufacture's site for his drive. He finds the new upgrade, downloads it,
and then installs it. After, his drive was not working as well for some
reason. It was making a lot of coasters. He tried to find a way to flash it
back, but he could not. This was in the days when DVD burners were many
hundreds of dollars for a basic one. He ended up having to replace the drive
to fix the fault. The new one worked out very well.

"A.Grnd" - From J4 (A4) - (Is that 'all ground'?)

"Logic Grnd" - From J4 (A2)(B3)(C3) and J5 (B4) - (Special Ground?)
"Reset" - From J4 (C3) - (I heard a rumor that this wire was key?[This is
specific to Tron])
"Unreg" - From J5 (A1) - (Unregulated?What does that indicate?)

Note the "J4"and "J5" indicate the connector, the (letter/number) code
indicates the position as noted on the tables here: PS Test Results Table
(http://home.earthlink.net/~rescuetron/docs/pstest.htm)

"A.Grnd" - From J4 (A4) - (Is that 'all ground'?) Analog Ground.
Ground of the analog section of the circuit. This is separated from
the logic ground in order to prevent digital noise' from getting into
the audio.
"V.Batt" - From J4 (A5) - (Something battery?) Yes, probably the
supply from a battery.
"Logic Grnd" - From J4 (A2)(B3)(C3) and J5 (B4) - (Special Ground?)
Ground of the logic section of the circuit.
"Reset" - From J4 (C3) - (I heard a rumor that this wire was key?[This
is specific to Tron]) Can't help you here other than the obvious.
"Unreg" - From J5 (A1) - (Unregulated? What does that indicate?)
Unregulated. This is the rectified and smoothed voltage from the
transformer before it feeds the voltage regulators. For the 15V
winding, this voltage would be around 21V with the supply unloaded.
The 5V unreg supply is probably from the 8V transformer winding which
would be at around 11.2V when unloaded.

Also (according to the documentation), dxterm (DEC term). I don't have a test
for that, but thought it implied that dxterm would support soft fonts as well.
But it doesn't (or else the test I wrote against a vt420 is too fragile to work

I've tried doing this with a 1 KHz 3vpp signal (AC coupling), a 1.5v
alkaline battery (DC coupling), and an open circuit (AC and DC
couplines). The behavior is the same in all three cases. I will try
short-circuiting the probe to see if the behavior changes.

The glow plug relay on my diesel Mercedes, an 83 300SD has two sets of
parallel contacts but only uses one because the other has a gap of about
0.035" when the first set closes. I thought this was due to improper
alignment and I bent the other arm so that both would make contact. The
other day I found another relay and noticed that it had one set of
contacts
spaced so they didn't close. Are there any experts out there that can
tell
why they do this? My guess is that the open set is a spare for when the
first set wears too much. But that doesn't make sense because two sets
working in parallel wouldn't wear as fast. Also would like to know if
anyone has reversed engineered the circuit as it has an IC and a couple
transistors. The circuit acts as monitor to make sure glow plug no. one
is
drawing current and then turns a dash light indicating that the plugs are
heating and when it goes out in a few seconds it OK to hit the starter.

FWIW, only one set looks like full current contacts. IMO, it may be a
relay
used for other purposes and they don't want to run current through the
light
duty points.

The VT525 isn't graphical. It's a very nice colour text terminal though,
that just plugs straight into a VGA monitor.

(The VT330 was an interesting beast: if I recall correctly, it could

The VT330 is the monochrome brother of the colour VT340. (I'd like a
