Steve,
Thank you for the internal eng, perspective. Appreciate this.
Yes, I do suspect some caps have taken a powder!
But, I have NEVER taken a flat panel apart! I think I still have tools
to do this.
Just NOT where I was going.....................
Yes, I run my panels at 60Hz.
The 'bars' are stationary. They appeared over time. They remain.
Yes, I will try a new video cable.I have several!
Grounds are confirmed good; well unless the screen went really hooy.
Thank you for your share.
Duncan

From what you describe, Duncan, I suspect that an electrolytic cap in
the power supply has gone bad. Most panels have a 60 hz veritical
rate, so if the bars are stationary, most likely they are line
related. The only other possibility would be that there is a bad
ground somewhere, between the video card and the monitor. You might
try swapping out the video cable or just re-seating it (if that's
possible).

Don't run off to Dell. They have no data. Spend time there today.
The panel is a 20.1 in wide-screen. I bought it DEC 2008.
I am beginning to see bands of white/light-gray running vertically
(top-to-bottom) when viewing my standard desktop image (WinXP).
These bands are ~0.250-0.500 inch wideand they are
displayed at seemingly regular intervals from the right edge toward the
middle of the screen.
Yes, I accept that the video card is old; a Matrox G200 PCI w/8MB
Ram. Fine. This screen did the same connected to an nVidia 5900 GT.
I suspect this panel is dying. [SUX2BME]
Might you opine?
Thank,
Duncan
