Dell monitors are mostly rebranded monitors. The part number of the screen is on the back. But you're better of finding another monitor with a different defect or buy a new one.

Many monitors seem to me to die due to a flyback transistor in the horizontal circuit. Or... the older ones did that. These days, they often have weird hybrid ICs which seem to have everything possible, including the kitchen sink, in them (in other words, you can't find a simple English phrase to describe their function since they have often a number of partial functions tossed together in them.) I haven't opened up, for fixing, a monitor in years. Only to salvage parts, lately. But the serious stress, with high refresh rates and big screens requiring higher voltages, is in that horizontal circuit. That's where the volts/second are murder and where I tend to start first, if the external observation appears to suggest that problem. I also think those transistors are getting harder to find -- and FABs don't like making them, I suspect. (Probably just waiting for the day that cathode ray tubes die a final death.) And parts for monitors, in general, aren't easy to find for hobbyist types, anymore.
Years ago, I visited a repair facility. As miso mentions, they also focused on the higher end monitors. Because, as they said, they couldn't afford to spend the time needed to actually repair the cheap monitors. Buying a new one would often cost less than their labor costs to open a dead one and intelligently look around for the problem
-- let alone fix it, afterwards.
Can you describe the problem, at least? Someone (probably not me) may be better able to make a suggestion of where to look.
I suppose if I'm lucky to find a monitor with a cracked screen and the same monitor with a dead power supply but good screen, I might get somewhere. I'm assuming it's a pita to order a screen from the 'Happy Pixel Factory' in China.
Thats about the size of it. Though I do have some salvaged screens, most of the time they are not worth the space to keep them. By the time you have added a labour charge its cheaper to buy a new monitor.
I've never seen that monitor in the flesh, but the S-PVA screens are supposed to be very good. It is an alternative technology to the IPS schemes used in most high end monitors. The TN screens are the cheap ones you should junk if they fail.
If you end up looking for a new monitor, a few of the HP units are S- PVA, as well as Dell via Samsung. Most of the displays for graphics work are still variants of IPS. There is a website out of Germany that does reviews detailed enough to spell out the technology employed.
It takes a lot of technology to make a LCD approach the quality of a CRT, or plasma, if they ever made one of desktop proportions. Some of the NEC displays have a field flattening feature that alters the intensity of the data on the fly based on the location on the screen, in order to keep the intensity uniform across the display. This can be switched on and off, so I assume it slows things down. When you select the feature and see the illumination go flat, you really can't believe the crap you were watching prior to correction.
