My computer says no signal - E-Machines eMachines W2686 PC Desktop

make, model, year? use obdii scanner (1996 & later) to get trouble code if there is? (older model may have manual procedure for this, search). typically the signal/s comes from the computer (ecm, or pcm whichever the mfr. of the vehicle calls it). check fuses, & relays (if any) to the computer. some design, the cam sensor provides signal to the computer to give signal to the injectors..

It could be that your crank sensor is bad or your ecm. your crank sensor sends a small amount of voltage to your computer telling it that you are trying to start your engine the computer in turn sends a signal to the injectors telling them to pulsate because you are trying to start the engine but if your crank sensor is bad and sends no voltage signal to your computer your computer doesn't know you are trying to start your engine therefore it doesn't send the signal to your injectors telling them to pulsate. If your crank sensor is sending a signal to your computer then your computer is not sending the signal to your injectors more likely a grounding issue through the computer I have seen this before let me know how it goes.

no input or signal means that the monitor is not receiving any signal from the CPU and if the power light is amber then and the cpu works fine then there could be a problem with the cable connecting the CPU and the monitor ...check the cable.

Signal source refers to where the signal originates. For a computer, the audio signal's source is the tower itself, so the output from the tower connects to the input to the speaker, completing the connection.

The router is required in situations where a connected computer requires to share signals with another computer that has no signals. The router would turn on to recognise a computer that has wiifii only lacking the transmission of signal to another computer. Routers are required in situations where the owner has more that one computer. Consult with an internet services provider to attain signals to the computer. Once achieved, acquire another compute that requires sharing the signals. Once the router is turned on in this situation, wiifii on the computers are detected on the router that captures to distribute the details of networking.

"no signal" means that the monitor is not receiving a video signal from your computer or laptop. This is normal if the compouter is OFF and the monitor is ON. Is the computer still on and connected to the monitor?

Keep the computer on when you plug it it
so have the computer ready

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.

hey they take of these things when they design a computer... so don't worry about these things...

You need to use the Fn key on your computer to change the signal so your monitor signal projects through the projector.
On my computer I use the Fn key and F4 and it will then send the signal through the computer to the projector.
