I bought a used 15" IBM LCD monitor that is not very bright even when the controls are turn up to the max. I'm pretty handy with electronic repair. Is this a somewhat inexpensive repair like changing some bulbs? (not an expensive screen as the picture and colors are fine)

Well it does sound like your monitor is going to die soon. You'll just need to replace it, trying to fix a 7yr old monitor is exactly worth it. Fixing it would be costly so you may as well buy a new one.not sure what you mean by integrated with drive unit. some elaborating would help :D
you can use on all vga cards(you dont need any special controler), this monitor has a USB hub and its is detected normaly on winxp or above, and the vga cards detect the monitor auto. i give you the monitor specs, take form website

filmorepetty, The "switch-mode-power-supply" has gone into SHUTDOWN mode because it has detected a fault with itself or another circuit. Or it could have just blown a small fuse on the circuit board of the SMPS. Will the pilot lamp light-up? Did it have a clean, bright, crisp, image displayed on the lcd panel the day before? How old or how many total (approx) "ON" hours of use has it seen? Do you know that 98% of lcd monitors use "cold-cathode-fluorescent-lamps" and an accompanying "electronic ballast" circuit to generate the WHITE LIGHT needed for you to see the pretty colors on the LCD Panel?? Same basic lighting technology as the new screw-in socket curlie-Q CFL light bulbs! Only your monitor's lamps are thinner and straight and hung on the rear of the LCD panel. A failure of the ballast circuit could cause SMPS to shutdown. I suggest you visit some other websites for more info on what other owners are doing to try and repair BLACK SCREEN lcd monitor problems. The first place to go would be YOUTUBE and search and view the longer 6-12 minute video clips of "LCD monitor disassembly" and "LCD monitor repair" just FYI and to know what you are dealing with??? Your unit could also have FAILED electrolytic filter capacitors on the SMPS printed circuit board. I'm 12fixlouie Bye for now.
wow a CRT that even glows at all , and you wonder why its dem
the electron gun cathodes get weaker every day of its life.
all CRTs do that, not one or even TVs using CRT
the red gun always goes dim first so we crank it up in the OSD.
if it fails on all PCs, the monitor is bad, a 5 min test. and bingo
then if the monitor is known bad then what.
the OSD screen ever seen that, and the front panel key marked MENU/?
go there and play with brightness, and even the electron gun tuning, the page for that is RGB, Red Green blue.
adjust them so white looks OK.
but if all are dim, that is normal for old CRT,
we only get like 3 folks a year stuck in 1990s... or older.
the labor to fix it is 3 times a new LCD LED display.
land fill time. like the other billion made, and scrapped
