Did I fry the monitor

Also, try a different monitor on the
customers computer. CORRECTED... If the monitor doesn't work, it is
not a monitor problem.

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

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.

This is a reasonable remedy.
 
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)

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?
 
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.

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.

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?

Sorry, too late, I gave him a $75 credit, he's more than happy.

The monitor was 3 years old. I don't know the 3 year depreciation value of
a monitor, but it has to be considerable. I will also help him find a
suitable deal for what he needs, on my own time. I'll also unpack it and
set it up for him, pro bono. Right now, he's using an old CRT that he had
sitting around in his store.

The guy is also in business, he asembles and sells boats. During our
conversation, he mentioned that this sort of thing has also happened to him,
he understands, and appreciates my impartation.

Thanks for replying.
