Hi:

Within the first five-ten minutes of booting up, my Gateway Pentium II 450
(Ev 700 monitor) has intermittent fluctuations in the display. The image
"wiggles."

Thanks.

Try the monitor on another system. If if the problem travels, replace the
monitor. If it doesn't, you've
more likely got a faulty video card (which wouldn't be out of the question,
particularly if it's an nVidia card, which seem to fail after a few years,
relatively frequently).

Try the monitor on someone else's computer and see if it still does
the big "wiggle". That way you will know if it is the monitor or not.
If its not the monitor then you probably got a bad video card if you
are using a card vs integrated. If you are integrated off the MB then
your problem is in the MB. If it is the MB and only the video driver
part of the MB then you can possible turn off integrated video and
install a video card and get back to normal.

If it's an EV700B (Millennium type), that's a known monitor issue.

I have the same moniter on my repair bench and am working on the same problem right now. Mine flickered like yours did and all of a sudden just went out. I have a burned resister R798 near the horizontal flyback. This resister is part of a secondary power supply in the moniter as the voltage from this supply is derived from the flyback. This resister burned past recognition. Can anyone open up one of these moniters and tell me the value of ths resister I know that it is a 1/4 wat resister. there is also a spark gap right next to this resister. any help would be apreciated.

It might be helpful to state what monitor you are talking about.
Secondly, resistors don't normally fry for no reason. Odds are good that
some other component is shorted/faulty. Can you follow where this
resistor connects too? My good wild guess would be to the horizontal
power driver and/or the flyback. It could be something else too, but I
would check this out first.

And if it is the power driver, careful about using subs from a cross
reference manual. Even though the book claims it is a replacement, some
won't work as they can't handle the high frequencies.

And if it is the flyback, well they cost a lot and it usually isn't
worth the cost for a replacement and getting a new or used monitor is
usually less costly.

Right. With replacement monitors driven down to giveaway prices by the rapidly
falling street prices of LCD monitors, hardly anybody repairs a monitor any
more. If the owner of the monitor is nearby, I would be happy to sell a
replacement (17", 19", or 21") with warranty for cheap with a warranty. I am
near Routes 2 and I-495 in Massachusetts, northwest of Boston.

People are giving away good monitors on craigslist. My local exporter of old
computer gear to 3rd world companies is paying less than $10 each for working
name-brand 17" monitors.

It does not make sense to attempt repair of a failed electronic component inside
a monitor any more, even with complete circuit diagrams. As you state, there
is a strong likelihood that more than one part has failed, and one cannot
dismiss the consequences of a very high voltage electric shock... Ben Myers

Agreed. Out here on the left coast, you have to pay someone if you want
to get rid of a monitor, finding someone willing to take a perfectly
good monitor is nice.

Is that a resistor or is it the high voltage diode?

The moniter is a EV 700. Yes I know I can go out and buy a new one but as an old tech I love the challange of repairing the existing insted of buying new. Plus I am on a fixed income and can not even afford to have a freebe shipped to me. I have already checked everything in the area for shorts to ground and found nothing. I am having trouble with cockroaches and found 1 chard in this location along with the resister.

For freebies that you simply have to pick up, no shipping, try
www.freecycle.org

Try craigslist in your area for a free or really low-cost monitor. I've picked
up a few for free and put them in my warehouse to sell for not much money at
all. Usually when I sell a late Pentium 3 (rarely these days) or a Pentium 4
system, the buyer gets a free 17" or 19" monitor with the system, with free
replacement of the monitor within 6 months should it fail... Ben Myers
