Diagnose a failing monitor?


Hey guys-

I believe my monitor (Dell 1028L, 17 inch CRT) may be on it's way out. It just happened this morning...gamma seems to have dropped a few levels and lots of horizontal interference. Since I have not made any adjustments and the monitor is now 5 years old it's time may have come.

It diplays poorly in X and console which leads me to believe it is hardware issue. Is there any thing I can do (tried turning on/off) to try to save this thing?

Thanks is advance,

g00$e

what does you XFree86 config file look like? (only the relevent bits, don't need the mouse settings, just monitor and graphics bits).

do you know if it works ok in other oses or computers?

Thanks for the reply.

I don't believe this is an X issue as when I switch to run level 3 (multi-user, No X) I am have similar problems. Midnight commander exibits ghosting around dialog boxes, gamma is off, etc.

But I am not very hot on X so here is the relevent portions of my XF86Config-4 anyways:

Code:
Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "Monitor Model"
        HorizSync    31.5 - 64.3
        ModelName    "Monitor Model"
        HorizSync    31.5 - 64.3
        VertRefresh  48.0 - 120.0
        ModeLine     "1024x768@75" 78.8 1024 1040 1136 1312 768 769 772 800 +hsy
nc +vsync
        Option      "dpms"
EndSection

Section "Device"

        # no known options
        #BusID
        Identifier  "NVIDIA GeForce 2 GTS (generic)"
        Driver      "nvidia"
        VendorName  "NVIDIA GeForce 2 GTS (generic)"
        BoardName   "NVIDIA GeForce 2 GTS (generic)"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "NVIDIA GeForce 2 GTS (generic)"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Depth     24
                Modes    "1024x768" "800x600"
        EndSubSection
EndSection

Section "DRI"
        Mode         0666

hmmmm

if you're getting this problem in the command line mode then yes, very probable that it is your monitor that is messesd up
since the kernel has extremely low level drivers built in so that it can run on pretty much anything.

Sorry couldn't be anymore help

Try the monitor on another machine. Just to make sure.

Just a thought ..... have you rerouted any cables or added any speakers nearer to the dead monitor - or any mains leads / power cables dropped nearer to your monitors data cable? (Just thinking about magnetic interference)

EDIT - Or even simpler - does it have a Dagauss button (some monitors normally Degauss on power up - but not all)

or have you tried playing with horizontal or vertical sync rates. I've got them wrong before and it screwed the monitor up good and proper

Hey-

I actually typed out a post earlier but my MS Wireless Mouse seems to like to go to sleep after 1 second of usage. So while frantically trying to get it to work (a button click usually wakes it up) I did something to make Konqueror puke. Bye Bye post.

Anyways...When webtoe suggested I check the monitor I thought to myself..."I am sure it is the video card". Well...when crabboy reminded me that I better check the monitor again I figured I should listen to you both.

So I hooked up the monitor to my web server (had to install X grrrr) but what do you know...it works fine. It now is no longer a monitor problem but a video card one! The cooling fan on the GPU crapped. This is the second one! The OEM one was the cheapest POS and died after a few months. I went to Radio Shack and got one with same voltage and similar size wtih slightly less wattage. With a little sauter (sp?) and a drywall screw to hold it to heat sink it ran fine for two years. Until now.

I was able to scavenge a S3 4 MB PCI card out of the closet to get X working at least but moving my video card from AGP to PCI or something has caused my sound card to stop functioning (can't find device /dev/mixer).

Thanks for all the advice and tips guys. BTW Svha good suggestions. I tried to route cable as clean as possible and did a degauss but no success.

I guess my next step will be to figure out if the damage is permanent or was temporary due to a lack of cooling. I guess I could drop another 10 bucks to find out. This may be a much better solution than 70 for a new one.

Great forum here and once again thanks for the help.
