The monitor doesn't even try to go on. Can I identify the problem by this error code? Any suggestions? Thanks in advance

Re: Green-Amber-Amber Code?

I know that my post is very belated, but I think, will be helpfull for someone henceforth...
First of all, there is one "chronic" problem with LG monitors: solders. Check soldering of Video Amplifier IC303, Flyback Transformer, Q833( ! 210V) , deflection coils socket, Vertical IC601, XTAL X401 and so on...
In Your case, probably the cause of "green, amber, amber" lights is lack of 15V on the Verical Amplifier IC601. DPMS is activated, and monitor does not work at all, even power off.
Replacing Q912 (2SA1273) solve the problem. I replaced him with 2SA1680 PNP 1A 900mW 60V, and all is OK.
This problem is fundamental for ALL 17'' Flatron monitors, repaired by me (over 30).

Wish Happy Repairing!

Best regards, Ico.

My monitor no display and light is blinking

if the monitor light is blinking this suggests that, there is no display signal coming from the tower. This could be because of the following .

1. Bad video card 2. Bad video software

To check,where the problem is , power of the system tower and remove the power cord from the back of the tower. Press and hold the power buttoon for 10 seconds and the reconnect the power cord and turn the tower on. Check if there is any display or the status of the light changes from amber to green for even a small instance.

If the light changes to green and back to amber the video port on the tower is bad

Alternatively you can connect the monitor to another desktop or laptop to check if the same is working correctly.

Most LCD monitor (depends on the brand) power indicator light will either turn from Green to Amber, or flashing Amber, or flashing green, when it does not detect video signal feeding it.

My monitor is black even though the computer is on

Sounds like either the video cable is not connected or the video card is not sending the signal to take the monitor out of standby (amber) your monitor need to go from amber to green as the PC starts.

Flatron monitor

You need to check the monitor cable if it is correctly connected to the motherboard port. If the analog display or no signal it means the monitor cable should bot connected. If you have a video card in your motherboard you can plug your monitor cable to the external video card.

LG Flatron L1710S Monitor stuck in Power Save Mode

Try wiggling the Cord on the backside of the monitor.. Not the Power Plug Cord, The Other Cord that attaches to the PC. Do this once the monitor turns off , grab ahold of the cord about 2 inches from the back of the monitor, then bend the cord to the right, keep bending from the right to the left a couple times to see if your screen comes back, if it does, than you have a Loose connection and this sometimes causes the Symptoms you are receiving.. Hope it helps.

Monitor Acer Problem

I agree it isn?t the monitor but I would suspect the video card you are connecting it to or the PC itself. Generally if a monitor doesn?t detect a video signal it will go into hibernation mode, typically displaying a no signal warning and changing the LED color from green to amber. When you start the computer is anything displaying at all? Are you sure the PC is powering up and booting?

Flatron LG monitor safe mode

Your monitor goes to Power Saving Mode when the signal it is receiving is not correct. In all probability this is not a problem of the monitor itself, rather you should check the connections and the computer the monitor it's connected to. For example you could try a different RGB cable and try it in a different computer.
