Monitor is flashing - BLUE, BLUE-ORANGE, BLUE, BLUE-ORANGE

Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Good luck.

Check all connections.

the monitor appears to be in sleep mode
google the model no go from there

I disagree with ikkenom only due to the symptom of the flashing blue light. This would indicate to me that the monitor is not getting any display signal and is in sleep mode at least the is what happens on my Samsung monitor. Used to be that they use a two color led in the monitor, green when ON and getting display signal and amber or orange when in sleep mode. I would check the computer by trying a different monitor. If you have a second monitor, great, if not, maybe a friend will let you bring your computer over and try the computer with their monitor. Could also be a display adapter setting. Do you get any change when you first turn on your computer? i.e. Do you get the BIOS or manufacturer screen when first turned on? Also if you disconnect the monitor cable from the computer and power cycle the monitor, do you get a No Signal display for a few seconds before the monitor goes black and the blue light starts flashing?

Let me know what happens with the testing above or if you need further instructions to carry out testing.

Thanks, Jim

Kathy...have you tried connecting another monitor to the same video card and computer? It could be...

1. Video card defective
2. VGA cable from computer to monitor defective...look for bent pins in plug.

The VGA cable from the computer video output carries three distinct colors...red, green and blue. Likewise one of these colors may not arrive at the monitor correctly or at all. The results being that all colors are incorrect.

CONNECT THE MONITOR DIRECTLY TO THE WALL OUTLET
CHECK WHETHER YOU GET CHECK AUDI SIGNAL OR NOT OR ANY MESSAGE---HTEN CHECK FOR THE CABLE---IF STILL THE ISSUE PERSISTS CHECK IT WITH A DIFFERENT CABLE---
THEN CONNECT IT TO THE COMPUTER MAKE IT SURE THE COMPUTER IS TURNED ON AND THE POWER IS GIVEN TO THE MONITOR AS WELL----CHECK THE COMPUTER WITH ANOTHER MONITOR---IF THE OTHER MONITOR IS WORKING FINE THEN CONNECT YOUR MONITOR TURN IT ON AND THEN FLASH A FLASH LIGHT OR TORCH LIGHT AND THEN SEE IF YOU CAN SEE A DISPLAY INSIDE..
WHILE CHECKING FOR ALL THESE STEPS YOUR ISSUE WILL BE RESOLVED IF NOT TYOU GOTTA CONTACT THE MANUFACTURER FOR A FAULTY MONTIOR---

STEPS IN BRIEF:
DO A MONITOR SELF TEST
CHECK FOR THE LIGHTS
CHECK FOR THE CABLE
CHECK FOR THE PHYSICAL SIGNAL
PUT THE MONTIOR ON A DIFFERENT COMPUTER AND CHECK
CONNECT THE COMPUTER WITH A DIFFERENT MONITOR AND CHECK
FLASH A FLASH LIGHT AS A LAST STEP TO SEE A DISPLAY
IF THE ISSUE IS NOT RESLOVED THE MONITOR IS FAULTY..
HAVE A NICE DAY!!!!

Temporarily connect a different monitor to your computer, to see if your video-card is the problem.

Temporarilyh connect your monitor to a different computer (desktop/laptop), to see if your monitor is the problem.

Try a different "data" cable between your monitor and your video-output port.

Check the data-cable between the computer and the monitor, and try a different cable.

Or, try connecting the monitor to a different computer, to see if the video-card in your computer is not working correctly.
If necessary, replace the video-card.

Colours on your monitor are produced by "mixing" the 3 "primary" colours: red/green/blue in various proportions.

Or, if part of the monitor that produces one of those 3 primary colours has stopped working, then the resulting "mix" will have too much RED/PINK. Fix/replace the monitor.

The monitor is bad. Hopefully it is still under warranty.

Do you connect all monitor wires on ... Do you got with screen or computer some MSI thing... the monitor blue wire must connect that thing then that MSI or whatever must connect to computer
