First thing to check is the power supply cord that plugs into the monitor. Sometimes the internal transformers fail. Let me know if you have power to that. The way to check it is to plug the cord into the wall socket and use a multimeter tester set to DC Volts and see if you get voltage to it. Let me know if you get voltage there

My lcd screen switch goes green and a message appears "going to sleep" and the switch light goes yellow

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 flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.

LG L1730S 17" LCD Monitor

Hi Anand,

You need to check your power options settings and modify it , so that your monitor does not turn off automatically.

If you are using windows xp , go in control panel and then there would be an icon for power options , double click the power options and then you would find settings which read turn off monitor , turn off hard disk etc... select the turn off monitor to never mode or as per your convenience and you would have your problem solved.

Hope this helps.

On-off switch does not function

As in power switch? I don't think they make power switch replacements, you may need to either send it back to Dell (if it's still under warranty), or purchase a new monitor.

Just received Refurbished Advent CBE 1401. It is being replaced because power switch is faulty - but I have questions about machine. 1. When initially switched on the switch turned red is this normal? I...

1) No. The switch color should have been Green

2) No Signal on the monitor, indicates the monitor is not receiving a Video Signal from the computer.

A) Could be due to a faulty monitor cable.
Monitor cable is used on a working computer for a test,
working computer's monitor cable is used on the Advent for a test.

B) Could be due to the graphics 'engine' on the motherboard, or on the graphics card is bad.

[Graphics 'engine'.
Graphics Processing Unit. ]

If the computer is using Integrated Graphics, the GPU is on the motherboard.

(Integrated Graphics is also referred to as OnBoard Graphics. Meaning On the motherBoard)

You will know if it's Integrated Graphics, because the monitor cable will be plugged into the VGA connector, on the motherboard

Since you indicate an adapter was included, to adapt to a different port (Connector), it could be a VGA to DVI adapter, or a DVI to VGA adapter.

Your monitor may just have a VGA connector on the monitor cable.
Hence you would use a female VGA to Male DVI adapter.

Your monitor may be an LCD flat screen monitor, and has a DVI connector on the monitor cable.
Hence you would use a female DVI to Male VGA adapter.

Digital Visual Interface

VGA monitors are Analog.
LCD monitors are Digital.

A computer puts out a digital signal.

If a VGA monitor is used, the computer has to alter the Digital signal to an Analog one.
This slows down the video signal.

If your monitor (In any case. Not just this one), is an LCD flat screen monitor, it is best to use a DVI monitor cable, and plug into a DVI port on the computer, if available.

If your monitor is a VGA (CRT. Cathode Ray Tube), monitor, and you have a DVI connection on your computer, using the adapter will do you no good.

The adapter just uses the contact pins for VGA, that are present in that DVI adapter, and hence the DVI connection on the computer.

You're still just getting an Analog VGA signal.

Example of a female VGA to male DVI adapter,

If the Integrated Graphics are suspected to be bad, a graphics card is used in the appropriate expansion slot, for a test.

If the graphics work then, the graphics card is left in service.

After I test the monitor cable my next procedure is to suspect the Power On switch, or the Power Supply, and go to the graphics next.

The reasoning is that Power Supply failure, is the number one cause of computer failure.
The next is the Power On switch, then Electrolytic Capacitors used on the motherboard.

(Specifically, any Electrolytic Capacitors used in the motherboard Voltage Regulator Circuit)

If the Power On switch is bypassed, the diagnosis will reveal if the problem is the switch, or Power Supply.

Bypass the Power On switch, and the Power Supply comes on?
Problem is the Power On switch.

[One Power On switch I have found to fit a lot of computers. The Power On switch goes into the plastic Power On button, ]

Bypass the Power On switch, and the Power Supply does Not come on?
The problem is the Power Supply.

The Power On switch is bypassed using a jumper wire, from the green Soft Power On wire, to ANY black Ground wire. The contact made is a brief momentary one.

The jumper wire is used at the back, of the 20, or 24-pin ATX main power cable connector.

Power button on view sonic monitor does not power up the monitor; is it repairable

Please check the power cable if it is not loose. Also check the power switch if it is working. The power switch button for your monitor could have been damaged. But yes, it is replaceable.

Monitor will not turn on including power switch

I suspect the power supply for the monitor. Try a power supply from a working monitor. If you have a used computer store nearby, take your power supply to them and try it on another monitor.

There is no need to turn off a monitor using its power switch. Monitors automatically go into standby mode when they are not receiving a signal. In standby mode they use less than one cent of electricity per day. If saving electricity is your goal, raise the temperature in your home by a degree and run the air conditioning less.

Monitor shows ''NO SIGNAL''

This is normal. The monitor is telling you it is not getting a signal from the computer, which is true because you've turned off the computer. The monitor power is still on, however. The monitor power is not controlled by the computer power switch. Just turn it off with its power switch after you shut off the computer.
