try the user forums on Dell's website, the guys there can cross-reference the part#s to which models they fit.

sounds like there is no red and blue output from the card. You can try to scope the pins to see if the signals are there or not.

What has happened is either the knurls on the shaft that go into the cast Al frame of the LCD screen have worn the mating hole smooth or the holes themselves have split. If your laptop is one of the...

maybe the tactile pushbutton switch has become inoperative. You can probably snatch one of those out of an old VCR and solder it up into the monitor.

I think that's a good deal, even with the circle. Maybe you shold search eBay for a parts unit with a good LCD of the same model laptop. that way you will have spares of other parts as well.

Usually you would reseat the PCB by moving it back and forth / up and down whilst it is seated on the CRT. For this, wear rubber gloves. I would not try to reseat using a screwdriver.
For those who...

I have seen this problem before, and my opinion is that it is the video card. The memory on the card is starting to go bad.

If you are brave enough, you can open up the monitor and try reseating the PC board that is on the neck of the CRT (Be careful) Sometimes corrosion can build up on the pins of the CRT and you will...

If degauss cures it, then a magnetic field is present somewhere in the vicinity. Did you get new speakers, or moved them around recently? Sometimes the magnetic field generated by the speaker's...

There might be an internal fuse, but chances are that as soon as you replace it, it will blow again. This is your opportunity to get one of those new flat screen monitors :-)

I have seen reports that certain brands of fabric softener will help to rapidly dissipate the static charge on the CRT. Maybe those sprays that eliminate clothing static will work, too?

I have seen this happen in older homes where there is a refrigerator on the same line as the computer. As the refrigerator's compressor cycles on and off, the CRT screen will shrink and then pop back...

The monitor won't explode, but it sounds to me like you need a new one. It is not really worth fixing. Sme of the possibilities of what is going on: weak HOT, internal arcing/shorts on the flyback,...

How's the video card? If it is not sending the appropriate H&V drive signals to the monitor, the monitor will go into sleep mode.

Monitors have a degaussing coil built in, which eventually should restore your colours back to normal. If not, MCM Electronics sells a degaussiing coil that TV techs use to restore the colours on a...
