No display on monitor.
Cause:
This issue can be caused by any of the following possibilities.
- Connections not connected properly.
- Monitor settings are not correct.
- No Post
- Hardware issue.
Solution:
Connections not connected properly:
Ensure that you are connecting the monitor to the back of the computer in the 15 pins or older computer 9 pin connection.
If the computer is properly plugged in ensure that the computer monitor is getting power.
If you are not receiving power from a known working wall outlet and the power cord is removable replace it with the one connected to the computer and attempt to power on the monitor again. If the monitor still does not get power or it is not removable it is recommended that the monitor be replaced or serviced at a local TV / Computer repair shop.
If the monitor is receiving power check the status light.
If the light is orange or flashing ensure that the monitor is not in a suspend mode by moving the mouse or touching the keyboard. If the computer does not get a display by moving the mouse or touching the keyboard turn off the computer and monitor and reconnect the data cable from the back of the computer and if removable the back of the monitor. Turn the computer back on, if you still encounter the same issue continue reading through the other possibilities.
Monitor settings are not correct:
Ensure that the brightness and contrast is turned up or attempt to adjust the brightness and contrast, if adjusting the brightness or contrast has no affect on the monitor continue reading through the other possibilities.
No Post:
Does the computer beep, when it is powered on and or does it appear that the computer has activity. If the computer does not beep or beeps abnormally it is possible that the computer itself is experiencing a hardware issue or is exhibiting a No Post.
Hardware Issue:
If you have followed the above recommendations and are still encountering the same issue it is likely that the computer may have either a bad video card or monitor. The best method of determining this is to do one or both of the following:
Disconnect your monitor and attempt to connect it to another computer. This can be a friend or families computerm, or it can be taken to a service centre.
Borrow a computer monitor and connect it to your computer. This will not harm the other computer monitor in any way.
If your monitor works on another computer it is safe to assume that the video card within the computer is bad.
If another monitor works on your computer it is safe to assume that your monitor is bad.
