Hi, 12fixlouie here. LCD monitor may have intermittant solder joint on power supply board inside unit. May only need you to resolder it to fix. Locating it is a whole other problem in itself!!! If not into monitor "teardown" and all the other stuff that you will need to attempt a repair, then let me know right away. 12fixlouie

My monitor displays analog rgb then goes to blank black screen?


Here's some tricks I would try. Something here, might help...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

Dropped keyboard. Now display on monitor says 1. Analog input in power save mode - press any key or move mouse to turn on. I have done both, neither works. I have turned off system and I see it rebooting...


Hello,

the message Analog input in power save mode means that your monitor is not getting a signal from your computer.

Maybe you moved the video cable while reconnecting your keyboard? check both ends of your video cable.

If you have a DVI cable, then your monitor has to be switched to digial input.

I hope this helps.

After starting the computer the screen is black and only displays digital analog on screen and the blue light is flashing. It then displays a box say "check signal digital analog." please help me. Thanx.


This blue light flashing means there is power to monitor bu NO video signal. No Analog or digital Video . analog is the regular plug for PC to Monitor, the other is HDMI digital or other digital. Check signal digital/analog means again: No video signal from PC detected.

Double check the monitor cable, both going to the monitor, and going to the computer. Ensure it's securely connected. If this doesn't change anything, try rebooting your computer. When the power light flashes, it's in sleep mode and doesn't detect either an analog or digital signal - so either your computer has gone into sleep mode (you can awaken it by hitting any key or moving the mouse) or the cable isn't attached securely. Since your computer is brand new, it's unlikely that anything has broken down already. Another thing to check is to make sure that the resolution in your Display Settings is the correct resolution for the monitor - although it's hard to do this if you can't see what you're doing.

Best of luck, hope this helps!

Computer monitor comes on for 1 seconds, flashes "analog power save mode" and then goes black.


Most monitors will say "Power save mode" when they can tell through residual voltage that the signal lead is plugged into a machine, but there's no picture being transmitted. The four states of a monitor are:

* Off entirely.
* Switched on, plugged into a computer but no video signal being received - usually displays "analog power save mode" or "digital power save mode" for a few seconds, then blanks. Comes back to life the moment a video signal is received. This state is the default in full power saving mode.
* Switched on, not plugged into a computer. Some monitors don't display anything, some go into power saving mode, some fly "CHECK SIGNAL CABLE" or a similar message around the screen. Picture is restored when the signal cable is plugged back into the computer
* On fully, receiving an image, and displaying.

Hope this helps.
