My monitor screen keeps turning off even when the

LCD backlight is faulty. Need repair.

all monitors worked new ,yours is 2007 made,
and most old ones are dead now, for sure older than 2010
and used 10 hrs a day the CCFL tubes are now DEAD or odd as H3LL.
blinking means sleep mode
is PC on , are PC fans all spinning?
turn on PC first, then after 30second (now) turn on Monitor last
if monitor is ok (PC not)the monitor tells you PC is dead.
so monitor is bad. what's new there? nothings ever.

CCFL are dead.
test and proof is here.

How old is it? Perhaps the Monitor is gone or graphics card or it could be as simple as a tiny switch that shuts-down the monitor when the lid is closed. need more info. What red light? I have a old Gateway MX6421 Laptop

This is usually a sign that there is no signal going to your monitor, check all your cables and then reboot.

tgordon60, If you know how those NEW "CURLIE-Q" energy efficient CFL light bulbs produce WHITE LIGHT, then you will know what makes an LCD display panel produce all the pretty colors and the WHITE BACKGROUND of the FIXYA web page!!! Only difference is that your "cold-cathode-fluorescent-lamps" are thinner and straight, and hung on rear of LCD glass panel and have a DC to AC electronic ballast called an "INVERTER" circuit to produce 600 to 1000vac to light them up. Get to my FIXYA profile and read my responses to other BLACK screen lcd owners to learn about all your options for repair. Follow any of the links to other web pages you find there. Your monitor not any different than ACER, DELL, VIEWSONIC, BENQ, SONY, AOC!!!!! 12fixlouie aka louie12fix

Same problem - unplug both computer and monitor - hold power button for monitor for 15-30 seconds...then power it back on and then power on the computer. Seems from other sites there is a power issue with the monitor - this worked for me.

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.

Unless there is inadequate ventilation, your monitor could remain on all the time with little ill effect. Actually turning on and off your monitor actually puts more strain on it then leaving it on all the time.

If the gateway screen is displayed for a moment and then just turns off, I believe the inverter board inside the monitor has broken.
What's actually happening is that somewhere in the board more voltage then needed is "leaking" in and the safeguards on the board turn it off to prevent damage.

I would go and get an estimate from a shop. If the price is within 30-50 dollars of a new monitor, get a new one.
