Turned on computer (Pavilion a1657c), HD light operates, Monitor has little window saying:
HDMI Input: No Input Signal
VGA Input: No Input Signal
Recommended Settings: 1920x1080 - 60hz
Changed from the monitor that came with it (HP f2105 digital ouyput) to my Samsung analog and same message comes on dark screen.
First, check to make sure the input selection switch isn't stuck, after unplugging the monitor power cable. It sometimes can get stuck, or just become damaged. If this isn't it, maybe it's time for a new monitor.
1. No signal from the tower (VIDEO CARD)
2. Bad cable or bent pin on the d-sub 9-15 pin vga connector.
3. Bad signal board inside the monitor itself.
Things to try:
1. another computer.
2. check the signal cable for bent pins.
3. check the video card in the tower.
Before you "think its a bad monitor" you always want to assume the computer first as computers are 9 times out of 10 why the monitor is not coming on such as BIOS errors, Bad video card, bad power supply etc etc.

You need to change the input signal, get into the menu on your monitor and change the signal from rgb to dvi, hdmi or vga dipending on what cable you using for connection.
There is NO rgb connector on that monitor
You would have got a CD with this moniter..
we ahve install that cd..
and its better to check the cables first which would be the
VGA CORD that is blue in colour which connects your moniter with the tower.
We can check the connections with the moniter for the Tower and then install the cd.
Is the green flashing on the tower or the monitor?
If it is flashing on the monitor, then it might be tht the monitor is not gettign signal from the tower.
To check, disconnect the monitor from the tower and check the monitor. If you get a msg on the screen like no input signal or check video cable, then 99% monitor is fine.
Check for the power supply light at the back of the tower.
Disconnect everything from the computer and then press and hold the power button on the comp for about 30 seconds.
Then connect the cables and check if it is working.
