Monitor not receiving a signal

If you know the vga cable to be in good condition and the graphics card / chip on the computer to be working ok, then the issue is an internal one with the monitor. In all probability the monitor has a fault on the circuit board that controls the signal and will need specialist investigation

This means that the monitor is not receiving a video signal from the computer. When it doesn't receive a signal, it goes to sleep. You should check to make sure that the video cable is tightly connected, and also, if you have another monitor around, connect the other monitor to the computer and see if it works. It's possible that your monitor has malfunctioned.

The monitor is going itself to the Power Saver mode.It is not a problem of the monitor.This happens when there is no signal on the monitor.The monitor will display properly when there is an output signal on it.Please connect it to the computer and check that the output signals from the motherboard are proper.Also check both DVI (Digital Visual Interface) and VGA (Video Graphics Array)cables on the monitor.

Thats because your TV is not high definition and cannot process the high def signal. serial hook up does not give a highh def signal.


Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

There's a set of buttons on the front where you can choose input source. Your monitor has probably been set inadvertently to receive a DVI signal while it's connected via a VGA cable, or vice versa. Other than that, check your connections. Remove the cables from their sockets at both ends, and ensure you connect them back snuggly and turn the screws hand tight only.
Good luck!

If the signal cable is detachable from the monitor, you could try with another cable... Regarding the power, I' not an expert, but if you're familiar with electronics basics, like risks of high voltage, soldering, etc, and you'd like to experiment with the unit, then I can give you some hints.

Hi Kathy,

Nothing you can do, it could be the laptop does not understand Digital Video Interface DVI

What is the laptop make / model?

the monitor gets the wrong signal from the computer (refresh rate too high or scan rate too high )
check the screen refresh rate from Display properties / Settings tab / Advanced button / Monitor settings
worse case: damaged hardware

The monitor doesn't receive the signal from the PC. It is either the PC not booting up or the VGA coard is faulty. Change the VGA coard. or try reseting the VGA cord.

You can try removing signal cable from pc.If it still says "Out of range" most probably main logic card or interface board as it is known in the lcd monitor could be defective.If on the other hand removing the signal cable gives message No signal ,cable not connected,try connecting monitor to another working known pc.If it still doesn't work the interface board in the monitor is defective.
