Power light going to blinking amber

I have an intermittent problem where the screen either doesnt come on or goes off into a pseud power save mode? - ie the power light blinks amber, occassionally there is a clicking sound in time with the blinkig, and the light on the power supply slightly flickers gently in time. I have tried it on other PC's o same result - now I am not sure if the problem is the power supply or the monitor. It does work occassionally for periods of time? Is there a loose connection in the monitor?? Any help appreciated. Thanks.

struggling to find a power supply vendor in the UK? either the wrong power or unclear as to the plug.

Is it OK to cut the plug off, if I can get the right rating and solder on?

the power supply is external to the monitor - do you suspect the internal 'receiver' of the DC, or the power supply doing the transforming.

Thanks for the help by the way!

Sounds like a problem in the monitor's power supply. This will need component-level troubleshooting.

When I referred to a problem in the power supply I meant inside the unit, not the power cord.

This will need component-level electrical troubleshooting performed on the internal circuitry.

Okay, I see.

While the monitor does have an external 12V power supply, it will also have an internal power supply (inverter) which boosts the 12V to the higher voltage needed to power the lamps.

I think the problem is in the internal supply (inverter).

Again, this will need component-level electrical troubleshooting performed on the internal circuitry.

Princeton LCD17 blinks off immediately

Check the VGA cord that connects from the PC to the LCD, try putting VGA cord properly to the LCD and PC, or change the VGA cord. saving mode indicates no signal from the PC. So either the PC is not booting up or VGA cord faulty.

Hi,
To help you better , could you let me know , when the system goes into sleep mode, the power light in the front of the tower is it amber or blinking amber or is it of some other color.

If the power button is blinking amber , the power supply on the unit is going bad.

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.

Problem with powerup for my screen

Although you didn't list your operating system, I'm assuming it is Windows and offering a suggestion to clear up the issue based on that OS. Go to settings, and then to control panel. Once in control panel look for "power settings" and click on "custom". This will allow you to turn off all power saving modes by clicking "never" on when the screen is turned off or goes to sleep. If the issue is caused by the power saving mode, this will end the problem.

Monitor doesnt come on , but the power light goes from amber to green. then comes on after 20-30mins maybe.

Maybe update your display drivers. PC appears to be slow.
Make sure you don't have a bunch of apps that auto start.
Do you hibenate your PC?
Same issue if you connect monitor to another PC?
If issue follows you to a different PC it says monitor. If it doesn't it says the first PC (that monitor is currently connected to) had a cpu/memory or a driver issue.

Good luck
