Question about Sampo P7011M (Silver) 17 in. Flat Panel LCD Monitor
Green light indicates the monitor is getting power. Nothing coming up on the screen indicates, No Signal.
No signal from the computer. This means the computer itself isn't working.
A bad power supply in the computer can cause this. A bad power supply is the leading cause of desktop computer failure. It is replaceable, and can be done by the owner relatively easy.
You may have a computer tower that the Power light comes on, you hear fan/s spinning, (Including the Power Supply fan), and it sounds like the harddrive is running.
ALL the lights in your computer use less than 1 Watt.
EACH fan uses 2 to 3 Watts.
A harddrive sitting there spinning in an endless loop, consumes about 2 to 3 Watts.
A Processor uses 51 to 125 Watts. Depends on what Processor it is.
A weak Power Supply will have enough power for lights, fans, and that harddrive sitting there spinning.
It won't have enough power to turn on the Processor.
[No processor operating, then the harddrive sits there spinning in an endless loop, because there is no processor to find the boot sector]
For a test, connect your monitor to a know good computer. See if it works.
Now connect that other monitor to your computer.
