Usually this means that one of two things is going wrong:

1. your monitor has overheated and now the power board that takes the AC electricity and covnerts to DC has a popped capacitor or something else (looks brown or muffin like at the top of the coke can like capacitor) or something else is overheating.
2. your circuit and chip that converts the information from the pc to the monitor cannot work stabily because it has received a power surce from the DC converter board or it has become damaged.
Sometimes the flat ribbon cable connecting the lcd to the information-translation board that the video plugs into is loose. Usually flashing is a sign of circuit failure due to overheating or something similar though.

**always disconnect your lcd from the AC outlet before looking inside of it!**

If you cannot take apart your lcd and check that flat cable, or see if the power board is burned or a capactior might be blown, send it to repair or purchase a new one if you have the money. You can always sell the LCD as parts to someone who cracked their screen and needs just that part.

Power blue light flashing when i turn the computer on


It depends on where the blue light is. Is the blue light on the monitor or on the computer tower? If it is on the monitor the monitor is having problems and needs to be serviced. If it is on the tower it could be an issue with the power supply.

Hello,

A flashing power light indicates a failure of the power supply, this will also cause the white screen. Here is a link to a page showing what parts need to be replaced to repair the power supply board and get your monitor back running again.

Gateway FPD1750 monitor's keep go black screen, no picture at al


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

My Lg Monitor wont show screen (Power Button Flashing)


The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.
