Hi!

You need to check on your CPU. You get the no signal informational message on your monitor if the computer itself is not running.

The beep may indicate different errors. It could be an issue with the a faulty memory card or the graphics (video) card. Try to use a blower to clean the inside part of the CPU. And then re-attach the memory card to their slots.

You need to take note how many beep it gives you. This could be very useful in helping you pin point the exact issue.

Monitor Hp w1907 has no input signal, how do I get connected and keep it from going to sleep


If you set the PC to go to sleep after certian amount of time than it will not put out signal to the monitor. You need to go to display properties (right click on the desk top)/screen saver -power/set the display to never turn off.

I see a gray screen only when I turn thePC on. I connected my monitor to my acer extensa laptop and still stayed gray.


The CRT monitors use RGB signals for displaying colours, most of the monitors dos'nt have colour setting option, This situation can only arise whenever the RGB signals are equally of the same strength, this is an indication that the chroma section responsible for colour distribution of your monitor is now working properly, you need to examine the RGB circuitry of your monitor, one more possibility is the data cable (VGA) has been tampered internally.

I am trying to connect my acer PC to a tv but get


The inputs on a TV are normally via the ariel and go into a pre-amp

To get a signal in you, would again, normally connect to the RGB or Video in which bypasses the pre-amp.

The VGA cable will be outputting a digital signal which a monitor will understand but a TV will not as it prime supply is via an analog signal

You may be able to get a connection if you process the signal through a freeview box which changes the signal from analog to digital

While trying to change channels, my t.v. displayed ''no signal'' and then shut itself off. Now, when I turn it on, it says no signal and turns itself off after a few seconds.


Turn the television on and as soon as the screen turns on repeatily press the input button or change the input to whatever input you are using from a source device. As long as you change it to anything other than RGB.

Your television is essentially a big computer monitor with multiple inputs and a tuner. When using your computer and shutting it down the monitor will go in a power save mode. You don't need to shut off your monitor due to this power saving mode. When you power up your computer your monitor automatically turn on.

With the VIZIO and the RGB (computer) input the television will act just like a computer monitor. When you have a computer connected it will power down automatically when you shut off your computer. When you turn your computer on the VIZIO will automatically come out of standby mode. This is through RGB only.

This is normal operation for the VIZIO but can see confusing when nothing is connected to the RGB input. If you change your television input to RGB it will sense no signal on the input and will go into standby mode after about 5 - 10 seconds. If you were to send a signal to the television through RGB it would automatically kick on.

RGB NO INPUT SIGNAL


Hi,

RGB stands for Red Green Blue. Your monitor isn't getting a video signal.

First, look behind your PC.

Pull the video plug and check the pins.

The should be three rows of them. Make sure none of them are bent over.

On the back of the PC, look at the connector socket you just pulled the plug out of. Is there another like it? (15 holes, 3 rows of 5)

If so and the original doesn't work, switch the plug to the other.

Put the plug back in and screw it in tight.

Reboot your PC.

Hope this helps,

Mike

AL2423W flashes 'No Signal' and turns off and on


Hi Guys,
This is a common problem with this monitor but I have a fix. Sounds simple but try it it works. Turn your monitor off, then turn it off at the wall, turn your monitor back on to drain any stored power, now turn it back on at the wall and fire the pc up and see how you go.
