    thankyou for such a fast response, for some reason suddenly now it is working perfectly ~lol~

    use compressed air bursts on each till it comes on to find out which one it is if it happens again?

Blank HP w1907


If the power light does not turn color and stay's green on startup, it is not a power problem. It is most likely the inverter. If the unit is in warranty, send it out ASAP. Contact HP customer care by email and have the issue logged in.
If in warranty, they will send you a box by FedX second day and have repaired.
This is a 19" monitor and will not be worth paying for repairs if not in warranty.

Screen shows message "no input signal" and monitor goes to sleep.


monitor show "no input singnal" error masage when not gating any type of video singnal ,
so if u realy check your monitor wires for correctty plugged in .
then:-

Two possibilities:

either the video/mainboard of the monitor is defective; or
the video card/ CPU is the faulty.

A way to verify is to try the PC with another monitor or to try the monitor in another PC.

thanks

Blank Screen & flashing button


It is one of three things, One is that it's not recieving a signal, mine flash when the computer is shut down, several monitors do this now. The second is that the either the video card is in need of service, or if you don't have a video card in your machine, it is either a connection that is intermittent, check the other end of the cable, or the monitor is in need of service, there is a circuit board that gives it a boost on start up. How old is the monitor and what brand? all the info is needed to go any further, thanks, if it is 5 years old more or less it is the monitor gone bad, more than likely

Dell Monitor comes on but no picture


The monitor isn't getting a signal from the computer, which is why the power indicator goes orange. There are two possibilities:

1) The computer isn't operating correctly. It may not be starting up at all when you turn it on, and you have a "no boot" problem to solve, or

2) The computer is working properly, shows all the signs of normal startup (hard drive activity, Windows startup sound from speakers, etc.). but video isn't reaching the monitor. There may be a problem with the video card (or on the system board if it's integrated video). Or the monitor itself is bad and not detecting the video. You can test this by connectng a known good monitor.
