Very weird Kogi L7EH '17 Inch Monitor Problem when Rebooting.

Hi

I have the KOGi 17 inch monitor, the model is: L7EH

For some time now whenever I reboot/shutdown my computer the monitor
just "shuts off." It will just turn to the orange light and not work.

I have to shut the monitor and computer off. Unplug the monitor, wait
about ten minutes, then plug the monitor back in. Start up the computer,
turn on the monitor and it will work again. This is *very* irritating
and I have no idea why it is doing this.

Can anyone offer some suggestions?

Thanks, ZG

Thanks for the reply, Ken. I regretfully do not have access to another
monitor in my current apartment.

I have an ABIT IC-7 standard motherboard; would it be this or my video
card? Which is a Gainward Geforce FX 5600 Ultra...

I'm confused on why if I unplug the montior for about 10 minutes and
restart my computer at the same time, it will be okay. Simply because my
computer reboots fine but the monitor just goes to it's orange led.

Thanks

Anything is possible, but some things are unlikely. Your monitor
should remain powered in a standby mode when you remove the Horizontal
Sync pulse. Once it detects the presence of a pulse the monitor should
again display the output from the video card. I have repaired many a
monitor and I have never seen failure the way you described. That does
not mean it can't happen, but it is very unusual. Do you have some
sleep setting in your "On Screen Display" monitor settings??? If so,
make sure they are off.

I would still take your monitor to another computer or bring a monitor
to your computer to see where your problem lies. Your quote: "Start up
the computer, turn on the monitor and it will work again." Suggests to
me that you have also shut off power to the computer when your monitor
fails to display anything. If you are doing that, then it might be a
failure of the computer and if there is no output from the video card,
there will be no display on the monitor. This is why I suggested you
either try another monitor or move it to a different computer.

If you can't test out the monitor, simply remove the monitor data cable
from the video card while BOTH the computer and monitor are turned on
and displaying data on the screen. Give it a minute and then attach the
video cable again. Does your monitor still display properly???

Hi.

I took off the cable for five minutes and plugged it back in and the
monitor still displayed properly, I'm not sure what that says.

I do not unplug the power to my computer; I do keep it shut off, because
if the monitor does not sync up when I reboot. I unplug the monitor,
wait 10 minutes and then replug it back in and start up at the same time.

This would indicate that your monitor is able to recognize both the
lack of a Horiz. Sync and the presence of one. If the lack of the
signal caused the monitor to go into a state that it failed to see it
again when present, it would indicate a monitor problem. The monitor
seems to be behaving as expected.

If power is simply attached to the computer power supply via the cord
but turned off, the only power still applied to your computer (MB) is
that required for a start up via your push button on the front of the
computer. If you remove the power cord or interrupt the power via a
switch on that power cord, all the start up voltage bleeds off from the
MB after several minutes and your MB starts from scratch. It is
critical to understand which of these two scenarios is occurring.

From what you are telling me, it sounds like your problem is in the
MB/power supply and not the monitor. Again, the surest way to prove
this is a monitor swap. Diagnosing a problem is done through the
process of elimination. Guessing can work, but it generally is quite
costly and time consuming.

Thanks for the reply again.

I guess next time I go home I'll grab a monitor from there. I don't know
what may be wrong with the power supply, since it worked fine all the time..

...However this problem started occurring when I moved into my new
apartment building.. which may mean that it might be not enough power
with coming from the building itself..? It is old...

That is possible. If your building is old and you have a poor wiring
connection resulting in a voltage drop, it could have an impact on what
your PS sees and its behavior. Again, guessing is not a very good way
to determine the cause of a problem. An accurate measurement at the A/C
source is the way to go. Start with the monitor, it is the easiest
first step.

Thanks for the troubleshooting suggestions. I believe it is not, in
fact, my monitor. I shut off my PC for 10 minutes and kept my monitor
plugged in and then restarted the PC in 10 minutes and the monitor
correctly synced up...

So I guess it is the video card or the power supply of the computer...
I'm guessing the AC just because this started at my new apartment and
it's old...
 
Hello, I have had similar (yet worse) problems with the exact model. I
have to power the monitor on & off to get any visual, but the picture
will only stay for a few seconds before it goes blank & light goes to
orange. I cannot get a picture for more than a few seconds. I have
worked w/the refresh rate, but nothing seems to work. This seems to
have occurred after it was moved for a presentation, which worked well,
but shortly after returning to my desk at the end of the day, it began
giving me an error indicating it was not receiving a signal. I had to
reboot & play w/the connections a bit & it would work. That lasted a
few days. Shortly after, it just began blanking out, intermittent with
changing of programs at boot, then just blanks out permanently & goes
to orange light mode. I replaced the connector cable & the power cable.
I have a second computer, it does the same thing on that. I have an
alternate monitor, which works perfectly fine on either computer. It
has been sitting in a corner of my room for the past year, with
occasional futile attempts. Please let me know if you figure something
out, as I have exausted all methods I can think of. I have searched
online & find nothing, I have sent an email to KOGI, with no reply.
Very frustrating!
