Is there a significant variation in voltages/current required?
Is any such variation mainly due to the design of the mobo? Or
is it mainly due to the choice of components (chipset and
processor)?
Any/all of these can vary current. One board may default
memory to different voltage, another may be running at
higher FSB speed, then the obvious things like chipset or
processor count too... these differences could offset each
other or add up to a signficant difference in some cases.
Even so, the difference between one motherboard and another
will often be much less than the difference between one CPU
or another (if large enough frequency or voltage, core
change), or comparing a budget video card to a high-end
model, or number of hard drives.

I'm using Windows 98 and I just bought a new monitor, a Samsung
SyncMaster 793s 17" screen. My old one was a Samsung Syncmaster 3 14"
screen.
When I went to change the monitor type on the Active Desktop list of
monitors, it obviously didn't have the newer 793s, so I tried to pick
a standardized monitor type from the list (at the top of the list it
says "standard monitor types").
I'm stuck between 2 options:
Super VGA 1024x768
Super VGA 1024x768 at 75 Hz
How can I tell which one I should pick? Also, does it matter if I
continue to use the monitor with the setting wrongly selected for the
older Syncmaster 3? What does this setting change, anyhow?
I should also note that the CD that came with the monitor only
provided drivers for Win2000 and up to Win XP, but not for Win 95/98.
Did the monitor not come with some software drivers? If not, you might
visit the maker's website and see if some are not available. Normally
you will have many possible settings if you acquire the proper drivers.
A 1994 set not digital?OK so at 10 yrs old I doubt it'll be a digital chassis. has it got pots to
adjust?

I now use my TEK465 oscilloscope's calibration output to generate ringing
pulses to test flybacks,yokes,transformers and video heads.I also now use
it to test ESR on electroyltic capacitors but would like to build a simple
and effective way to test transistors,diodes and resistors like maybe a
curve tracer or use my oscilloscope to test them.
Anyone have a simple effective design for a curve tracer either a stand
alone device or using my TEK465 oscilloscope?.Thanks in advance.

Look up what modes the new monitor supports and pick something close,
the
selection simply changes the resolutions and refresh rates available,
hiding
those not supported by a particular model. Personally I would just
choose
something generic, set it to the resolution I wanted, and then bump up
the
refresh rate one notch at a time until either the picture looks
distorted or
the monitor shuts down, and then back it off one.
Or the monitor blows up.
Most monitors should be smart enough to shut down if an improper refresh
rate is fed to it but not all.
However, it's very likely that any modern monitor should be able to
support
1024x768 at 78 Hz.
Based on simple economic principles, they are all "unrepairable." Given theMine is working fine (Sony SLV-D300P).
Ever tried to repair one? - Reinhart
How would a virus get on the machine in the first place? Obviously it's notI'm running a 386/25 with Dos 6.2 for billing. Recently it has been
having problems with bad sectors on the drive showing, and refusing to
boot unless you boot off a floppy and do a sys c: from the A drive.
Now it will not boot from the hard drive at all. Luckily I copied my
customer files before this happened. But there is alot of other stuff
I would like to get off it. To rule out a virus problem is there an up
to date scan program I can get that will run from a floppy on a Dos
machine? Thanks, Lenny Stein, Barlen Electronics.

My NV-F65 VCR has come into a state where it thinks there is a tape
cassette
loaded even though there isn't. It also powers down a few seconds after
turning it on.
Never really popular with technicians the old G-Mechanism.
Enjoy the frustrations of repairing or spend under $200 AUS to replace
with a new unit with more features.
I forget, but do the drives use both +5 and +12,
Yes.
and, if so, will this
arrangement be enough to regulate a supply?
I don't know what you mean by that.
Chip
Computer supplies need to be regulated to achieve the correct output
voltage, and both the 12 and 5 volt supplies may need to be loaded to
a certain level to achieve this.

The first thing to note is that by 550w, they mean *Peak*. Which
basically means nothing at all.

I am overlooking a small but significant link?
I never found anything 'real' on their site either. The only thing I came
up with earlier (but don't have handy) was a customer 'review' on a site
selling them and he claimed to have received an email from them, and
posted the data. The best recollection I have is that the 'real' numbers
were 20 to 40% less, depending on the power rail, than the amps put on
the sticker.

Ah. So they put both on the label. ok.
Hi, and thanks for your replies. So you're saying that it isn't just a
simple
"stuck sensor" problem, and need lengthy repairs?
Where do I find the mode select switch? (sorry, I don't have any
schematics for the unit)
