Having problems with your Samsung SyncMaster 204B 20.1" LCD Monitor ?
How to replace backlight in Samsung 204B. Monitor (3.1 yrs old) takes 10 min to warm up.
Asachs493, First go to YOUTUBE and view the longer and more informative video clips of "lcd monitor disassembly" and "lcd monitor repair" to see if you really want to do that!!! Also visit all of these sites:-- www.ccl-la.com/badcaps.htm and www.badcaps.net , www.lcdparts.net Remember tihs!! Replacing "cold-cathode-fluorescent-lamps" may not be the problem!! Your problem may be in the circuit that generates the high voltage that starts and sustains running voltage for the lamps!!! It's called an "electronic ballast circuit" and because it is in a lcd CCFL monitor, it is refered to as the "inverter circuit" (dc to hi ac voltage) The new "curlieQ CFL energy efficient, screw-in light bulbs have "converter" electronic ballasts!! (ac line to hi ac voltage) Just FYI. 12fixlouie

I have a Samsung Syncmaster 204B 21 inch lcd monitor that is having an increasingly darker screen. I have adjusted the brightness all the way up to no fix. When I turn the computer on, it takes nearly a half hour before you can even read the screen properly. Now though, the monitor has been on for the entire day, yet it has not gotten bright enough to do much of anything. Gaming on it is now impossible. Is the monitor on it's way out?
I have a SyncMaster as well, and it has been fine for 5 years. What you are describing sound like the backlight is getting dimmer, which is either a power supply or control board, neither of which are easy to replace. With good monitors getting bel ... PC Desktops
