Flat Panel Monitor blinks green & yellow, long time to wake up...

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

I recently was given a MAG Model 780 too. I found the input for speakers just today. When looking at the monitor, on the left side behind the monitor you should be able to feel a flat horizontal surface. If you lay monitor down, you will see 2 mini-plug openings. These are your input spots for speakers/microphone. I believe pink is speakers & green is microphone.

I think you might have the same problem I did with my E178FPb. I made a video on how I fixed it.

no data is getting to the monitor , check cable

take your RAM out and put it back carefully

Have you moved it recently? The monitor has a sensor that tells when the computer is on. Some times the computer settings tell the system to go in to standby mode and this will remove the signal that tells your monitor to stay on. Check your computer to see if it's running. Usually a green or yellow light on the machine will blink. If everything is good, check the pins in the cable from the CPU to the monitor. Check both sides. If a pin is bent or bad. replace the cable. Trying to straighten it might break off in the plug. Also, the video part of your computer may be bad. Try the monitor on a diffrent computer to see if it powers up.

On the monitor below the screen has these fine pink and green lines blinking across the screen all the time on my laptop. Can you tell me how to fix it or solve this problem?

THis is a problem of the invertor board.If you are technically able you need to disasseble the monitor and resolder components around the red or yellow inverter transformers.

probably ur compuet may be in standby so u have to beat the keyboard to wake it up .

here is the link for the manual; http://www.gemstarusa.com/downloads/manuals/GL-822.pdf page 14 runs through some procedures which should be worth a try - especially the idea to try the monitor on a different pc/a different monitor on your pc just to check where the problem is. swap any cables you can just in case. Hope this helps :)
