Default Did I fry the monitor

Hello again,

I was working on a customer's computer the other day, swapping out modems,
network cards, etc. After each time that I shut the computer down, I
unplugged all of the peripherals, the power, etc. But I left the monitor
on, while I unplugged and plugged the monitor cable from and to the VGA
port.

You know where this is going.

After about the third or 4th reboot, the monitor stopped working. I shut it
off, and on again, the light just blinks, and keeps blinking.

Did I fry the monitor, by leaving it on while I was plugging and unplugging
it?

The analogy that I'm about to offer my customer, whose eyebrow is now
raised, is from one of Richard Pryor's comedy skits, when he talked about
his father suffering a fatal heart attack while having sex with a woman
thirty years younger than he. "He came and went, at the same time". I.e.,
the heart attack was probably due, and while the activity may have catalyzed
the heart attack, it didn't actually cause it.

Any replies will be greatly appreciated.

Thank you.

In the shop we have monitors, keyboards and mice setup at all stations,
we then put customer PC on the bench and plug in the monitor,keyboard
and mice all the time without ever powering down the monitor first.

I take it you've confirmed it was the monitor, by trying it on another
computer?

It shouldn't cause any problems, and I have repaired video monitors
from the early '70s. The only thing likely to be damaged by improper
handling of the video connector is the EEROM that stores the PNP data,
but it doesn't matter if the monitor is on, or not.

It happened on your watch. Replace your customer's monitor,
free of charge.

I don't think its fried. Are you sure the problem doesn't lie in the card?
Some monitors leds blink when a video signal isn't detected. Also check for
bent or missing pins. I've seen that happen more than once!

It may not be the monitor at all. Since the light is blinking, that
usually indicates that it is not receiving a signal. I would check
the video card, or like some of the other posts mentioned, check the
pins on the cable. You didn't mention if it was an onboard video or a
video card. If it is a video card, these sometimes get bumped and pop
out of the slot just enough that they stop working.
Try the monitor in question on a different computer. If it works, it
is not a monitor issue. Also, try a different monitor on the
customers computer. Once again, if the monitor works, it is not a
monitor problem.
I can't count how many times I had the video card pop out at the back
end, just enough, it caused no video.
If none of this works, blame it on sun spots.

I'd think it more likely the monitor suffered ESD damage, if
you had actually unplugged the computer power cord (thus
removing it's grounding).

I've unplugged monitors still powered far too many times to
count, but there is some significant info missing like what
monitor this was.

Most monitors are grounded by their own 3-prong power cord, and I say
most, because if I say all, I'm sure someone will tell me there is a
monitor located in the far reaches of the world that is not grounded
by it's own power cord.

If I am repairing a computer, I usually never turn the monitor off
when I disconnect it from a computer.

I've been plugging and unplugging live monitors for many years and have
never
had the slightest problem...
Unless you hit it with a static electricity burst...it should not have been
harmed

That doesn't necessarily protect a monitor from ESD damage,
if the discharge is not to the connector shell or other
ground point on it.

Actually a ground on a device can even be an (enabler if not
really the "cause") of ESD damage, because it provides the
critical lower potential, path for this high voltage to
travel. The only remaining question is which parts of the
monitor would it cross on it's way to ground. It may be an
unlikely scenario, but then this kind of damage to a powered
monitor doesn't usually happen either, so "something" is
different.

We could go on and on about ESD, but the fact is that unless the pins
were touched, I doubt that ESD played a factor in damaging the
monitor. I can't remember the last time I "accidentally" touched the
pins on a monitor connector while removing it from the back of a
computer.
ESP says you would have a better chance of ESD causing a fire while
pumping gas, which would require an EMT, than ESD damaging a monitor.

I have had a loose pin that would slide back into the connector when plugged
into a computer, to say nothing about bent pins. Try pushing lightly on
each pin and see if one of them slides back into the connector. If it does
a light pull with needle nose pliers usually clicks it back into place.

Generally speaking, it's ok to plug in and unplug a monitor while it's
on. But that's a generalization; I've seen cases where there was AC
current leakage and you could see a spark as the monitor cable shell
touched the computer monitor socket, so all sorts of things can happen.

Obviously, try the monitor with another computer.

You dont get nothing on the screen in that case.

You do know that the video inputs have internal 75 ohm termination to
match the video board's output impedance, and that the other lines have
higher values, but are terminated? The least protected is the serial
data and clock lines used for P-N-P monitor ID EEROM. (The 24C08 is
typical memory for this)

I just spoke to him on the phone, I actually seem to be more upset about it
than he is. But, I am going to offer to give him a $100 credit off of his
bill. The monitor is a Dell SE177FP, and it retails at $179 brand spanking
new. I don't think he won't be satisfied.

I tried the monitor with another computer and cable. That was my hope, also.

Another monitor does work on his computer. And the fried monitor doesn't
work on another computer. No go. Sorry to say.

This is a reasonable remedy.

How effective do you feel 75 Ohms will be against thousands
of volts?

I'm not claiming we can assume it was ESD damage, only that
"something" sure as heck killed this monitor and that
something appears to be plugging and unplugging while on.
What do you think happened?

Please see my original post, and review the Richard Pryor analogy.

It's possible to buy new 19" LCD monitors for not much more than $100.

True but do you want to use one of those for your primary
display? IMO, a monitor's quality is vital enough to spend
a bit more, even if only to get an average unit instead of
low end.

If the monitor wasn't grounded, you won't have thousands of volts
across the 75 ohm terminators, only whatever voltage is dropped across
the terminator created by the small current available to flow through
the terminator.

I think it was a coincidence. I have had hundreds of pieces of
equipment fail between uses in the last 40+ years, no matter how well
they were designed. You have to remember that Murphy was an optimist.

maybe you fried the VGA card. Plug the monitor to another computer and see if it works. That will
solve that problem.

Dont give him $100 credit. Replace the monitor. You could find one for $100 new and he wont be out
any more money. Plus, he wont have to be put out to go out and buy one.

Maybe he didn't want a crap $100 monitor?
