2x Dell P1110 21" CRT monitors. #1 no picture, #2 very bright + retrace lines.

[[email protected]]

Hi all. First off, I have not posted in a newsgroup in almost 12 years!


I have two Dell P1110 21" CRT monitors with problems.

One of them was working fine then one day a mild "pop!" and the screen
faded to black. I can still hear the resolution (relay??) click when I
change the input selector with one of the inputs connected to a PC. Its
manufacture date is "December 2000". Is this a simple fix? I am
capable of replacing desecrate components.

The other monitor has been slowly getting brighter and now is very
bright and very visible retrace lines. I understand there is a resistor
I can change to correct this one?
Its manufacture date is "June 2000"

I am fine with making one good working monitor out of the two.
Any input is appreciated.
Thanks-
Colin

first one probably has a short in the deflection and will need proper
troubleshooting, second one seems like the g2 bias voltage is
incorrect, this is sometimes an open resistor like you mentioned, or
faulty screen control on the line transformer. impossible to really
diagnose by 'net.
However, judging from your post, I would suggest you take the unit(s)
to an experienced technician. neither are things you can fix yourself
without considerable experience in this sort of repair.
good luck, B.

Hi Colin,

For the too bright unit, first try using the 'colour return' feature
available in the OSD controls, 'Color' - then "Easy' or 'sRGB'. You
will see it as an option, but the monitor MUST be on (without going
into power save mode) for a minimum 30 minutes before the option is
available. If you have let the problem go too long, then it's unlikely
this will work, but is worth a try.
If Color Return does not do the job, the head on over to
http://www.geocities.com/gregua/windas/?200629 for info on
getting/using (freely available on the Net) Sony DAS alignment
software to correct the problem. Also info there (if you go to the
forum link on the page) on using the resistor method.

These steps must be followed exactally.
Hold down the middle button and power on
Release middle button
menu will ask for a 4 number code
code is 7711
enter code w/arrow buttons,,middle button to go to next digit
this is a timed response if you dont get it at first just keep trying till
you get the 7711
push middle button for O.K.

New Screen
Go to G1
reduce g1
fixed

If the repair starts looking expensive, $200+, think real hard about a
19" LCD. Actual "usable-viewable" screen size is almost the same as a
21" CRT and they can be had in the $250 for an off brand cheapie to $350
name brand with warranty, range.
I'm just waiting for my last Mitsubishi to die to go that route.

They're not based on Sony trinitrons are they by any chance ? Dell have used
Sony in the past. Check for the pure flat faceplate and the giveaway 2 'aperture
screen' supporting wires that are visible if you look closely.

I ask since my Sony CPD-530E of similar vintage has recently developed retrace
lines and poor contrast.

CRTs still offer far better contrast and viewing angle IMHO. Not to mention not
being tied to a single native resolution.
