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

How long have you had the monitor. It sounds like a defective backlight. Usually when the circuit driver for the backlight starts to go bad, the monitor will blink. If this is the case, eventually the monitor will not turn on at all.

jose54tony, Schematics would only be available from Samsung. Rarely do they let them out of there tight grip!! You may need to look at the smps board and inverter board to find bad transistors that may have also died (muerto) when the electrolytic filter capacitors failed. 12fixlouie

Replace the screen with a known working one. If it shows display then it is the screen which is broken, if not, then it could be the port on which it is connected.

Samsung monitor picture clicks off after 2-5 seconds...
Yes, It sounds like the backlight inverter circuit is shutting down. No inverter power, no backlight. On some monitors the inverter circuit will shot circuit the power power supply which makes the power light flash on some it just kills the backlight. You can usually check with a flashlight. Hold the flashlight pointed at the screen and see if you can see any of the icons or background picture. If you can then it is the backlight circuit or backlight tubes, usually the circuit.

Samsung, same exact problem - flickers on power up for a few min
This sounds like a power supply problem, how old is the monitor? If it is not new in the last year and is used regularly it sonds like a faulty capacitor in the power supply. If you are aware of the precautions necessary when handling capacitors and a moderatly competent solderer then you can replace then yourself - a complete set of capacitors usually costs around £3 or $5
