Question about Gateway HD2200 LCD Monitor
When I start my pc monitor will power on and off, cycling every 3 to 5 seconds, never turning on. Monitor is only a few months old. It was great while it worked. Give gateway the axe!!!!!

Check to see if the image is Dimmed. Chances are the power supply on the FPD is either dead or not supplying power to the back lights.

wjfarm48, Sure sounds like a power supply problem. How old is it? How many hours of use? Do you understand what a switch-mode-power-supply and an inverter supply is? If not, then here are your options. Check with Gateway to see if there is a swapout program. You box up and ship them your monitor+cash, and they return a REFURBISHED same model with new CCF tubes and inverter/SMPS. When you box up the monitor, follow this lead. "A 3 inch thick layer of breathable air shall be the only thing touching the lcd front panel" Next option is find some local TV/Monitor repair guy who can get parts and or replacement boards/CCFtubes from Gateway. Last but not least, is to repair yourself. Not Recomended.. But do a search on lcd monitor repair or Bad Capacitors In LCD Monitors or Repair of SMPS in LCD/FPD Monitors. Also check for videos on YouTUBE related to lcd monitor repair just for your own info. Here 's what you are dealing with. The light that makes your FPD bright white is generated by Cold Cathode Fluorescent Tubes (2) that require 600-1200vac at high frequency that is generated by an INVERTER which gets 12-24vdc from the SMPS. Almost the same technology is used in the new style screw-in curlie-que Compact Fluorescent light bulbs. Only they call the inverter a electronic ballast. Anyway, thats about all the info I have. Let me know how you make out in you quest to get your LCD up and running again. I'm louie12fix on fixya or lmistyrel@ aol.com BYE for now.

The backlight or inverter is going out on your screen.
Eventually it will just stay dark. You will need to replace one of the two if plan on keeping monitor.
If you find this helpful please rate so.

It could be a faulty power cord. Try plugging it in and moving the cord around in the areas where it takes the most movement. Do the same with the data cable to see if you get a response there. If your cables are fine, the problem is most likely hardware in the monitor - in that case you're better off replacing the monitor.
