HV shuts off in DOS mode

P

Guest
I have a problem with my Viewsonic G810 21 inch monitor.

When I go into my BIOS, after about 3 seconds the HV shuts off and will not
come back on. I also tried pushing pause during bootup to see if it was
happening in JUST BIOS or in DOS resolution and it did the same thing.

Once a Windows screen shows up, it turns itself back on and will never shut
down again. But my problem is, I need to get into my BIOS and I can't
because the monitor shuts off on me.

Any ideas???

On a side note, I still have my problem that when the HV shuts or I shut the
monitor power off before the HV has time to turn itself off, I get a green,
blue, and red splash in the middle of the screen. I've asked about this and
a few people replied but never gave me an answer. It ended up turning into
an argument because someone told me to buy a new monitor and another person
told them half the reason we have this newsgroup is to fix things and not
just give in and buy something new.

So if anyone has any ideas, please let me know.

thanks in advance
 
the colourfull spot in the center of your monitor is a so called
"glowspot-suppression" error. It happens either when a part of the
corresponding circuitry is defective or , more often, when the monitor
didn't have the time to charge / discharge the capacitors in that circuitry
properly. Usually it is a "no worry" when it does not happen always and/or
under all circumstances.

That your monitor switches off is probably a problem with merry advanced and
semi-sentient components:
Either your GFX-Card does use in BIOS-mode frequency under the limits the
monitor accepts as "operating" levels.
Example: I have an Amiga, and aside from the TV-Modes and VGA-Modes it has
several modes in the frequency range between these two. (TV: 15,6.... kHz
vertical, VGA 31kHz vertical and up)
Well: with all modes below a frequency of 31kHz one of my monitors switches
off by itself, thus I cannot use it for the humble Amiga, whilst my other
monitor, an Eizo Flexscan, even operates properly with the TV-modes.

Some Unlucky combinations of PC mainboard, BIOS and GFX-Board deliver either
frequencies or synchonisation-schemes some monitors can't handle at all or
loose the ability to handle them when their capacitors loose capacity over
the years and thus don't carry on correctly with the lower-frequency
signals.

I have nothing more than a guess to offer; but I
happily offer it provided that no one laugh too
much :)

Did you try disabling all of the power management
stuff?

Take care.

oh wow, so there is no way I can use this monitor in BIOS?

I have had a few monitors, 15, 17, 19 and now this 21 which is the only one
that has given me problems.

As far as the glowspot, it's all the time. Everytime the HV goes out as in I
shut the power off, the computer shuts off and the monitor's hv shuts down,
I get the glowspot.

I am wondering if it's going to get worse and eventually burn a hole in the
screen or if the flyback is on it's way out.


Thanks for your help so far.

Have you tested it using a laptop or another PC?
And, as someone else posted: Kill all the "helpful" stuff in the OSD,
and try it again.

Um - werent you selling a Monitor like this a while ago?
Was it by chance the Same one, and you wound up fixing it up and getting it
going? I remember you had ordered a Flyback?

This is more of a workaround than a fix, but there used to be
applications that let you configure your bios from within windows.
Obviously you still need to restart your machine. I cannot tell you
if people still write these little programs, and they must be quite
bios specific, so good luck looking for one...

Yes, I did have another monitor, same kind and I ended up junking it and
selling the flyback at a great lose which now I'm regreting because if this
problem I have with the splash when the HV shuts off, someone told me it
could be the capacitor or resistor inside the flyback.

But this is another monitor that had a problem with the HV shutting on and
off, and I resoldered the flyback and some other big solder areas and it has
worked fine except the splash when the HV shuts down and the BIOS thing.

Thanks everyone for your help so far.

I recently had a Mag DX17FG with a liquid Spill on it that Customer claimed
gave a Line down the Screen.

I could not confirm the problem, but I cleaned the Liquid Spill from the
PCBS for good anyway. Customer decided to let me have it , as they got a new
monitor anyway. Wound up selling this one locally recently - and I noticed
when I set it up in their Home, it did the same exact thing yours did when
the PC was 1st Turned on. (which is DOS MODE)

Repowering the monitor made it fine, but I suspect the monitor being in my
car on a cold morning, then going into a warm house had something to do
with it.

I also remember I adjusted the H & V Size controls on the monitor to get it
to look right in 800-600 and 1024-768 modes....so it could have been
something I did with the settings there that caused the 640-480 mode to
become slightly effected. I have seen other monitors behave this way..and it
sometimes is a bad . degraded component, but is very hard to isolate.


Maybe you want to try freeze spray and a heat gun?

Hardly a easy way: Try to find if your BIOS allows for a different
graphis-mode to be used on boot-up. switching the BIOS-Video to CGA or MCGA
is pukey, but could work. The other solution would be to track down the
input high/low-pass caps and measure them, replacing them if neccessary.

I have had a few monitors, 15, 17, 19 and now this 21 which is the only
one that has given me problems.

It's the most recent one I guess. Citing my old boss: "Clever devices,
clever errors."

down, I get the glowspot.

When you have the circuit-schemes for your monitor you could check the
blanking transistor which cuts off the RGB-Transistors bases, forcing them
shut, then the capacitors that support that transistor and those in the
"glowspot-suppression" circuitry. 100ľF transistors sometimes smell "fishy"
when they leak.

I am wondering if it's going to get worse and eventually burn a hole in
the screen or if the flyback is on it's way out.

Long-term you will get a slightly different coloured spot at the place of
the glowspot, and a reduced brightness and less vivid colours in that area,
as the phosphor ages faster. But that won't get noticeably during the next
year I guess.

Thanks for your help so far.

No problem. I'm happy when I can make use of my jobexperience somewhere. As
a student I hardly have time for them and my hobbies.
