Re: black screen upon turn on pc with monitor off?
Didn't stick out in bold as a new thread.
Well if you leave the monitor off during the boot up into windows or linux, the O/S will assume there is no display attached because it probe for EDID and didn't get a response. Newer monitors have EDID on the standby voltage to fix this issue.

Re: black screen upon turn on pc with monitor off?
What type of video card do you have? I have a nVidia card on Linux Mint, and the nvidia-settings program will give me an EDID. It will output it in either ASCII or binay, but I haven't figured out what to do with it after I get it.
There also is a Linux program that will fetch your EDID, and output some settings that you would insert into your xorg.conf file. When I ran it on mine, it gave me an error:

You may first need to create an xorg.conf file. To do that you first need to shut down X:
This will shut down the X server. If you don't get a login prompt, switch to a different terminal with this key combo:Code:sudo service mdm stop
Ctrl+Alt+F1
You can use F1 thru F8. Then login and create a xorg.conf file with this command:
This will create a file in your home directory named xorg.conf.new. Start the Xserver again or just reboot. Then you can open your new file and add the info that get-edid gave you. You will need root privileges, so open it like this (from a terminal):Code:sudo Xorg -configure
After adding the new info, save and close it. Then copy it to the correct folder with this command:Code:gksu gedit ~/xorg.conf.new
Restart the Xserver again or reboot. If the desktop doesn't start, then it rejected your changes. You will have to deactivate your newly-created xorg.conf file. Do this from a terminal by renaming it:Code:sudo cp ~/xorg.conf.new /etc/X11/xorg.conf
Then restart X again:Code:sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.bak
More info on get-edid:Code:sudo service mdm start

Hi everyone,
I'm dealing with an intermittent problem and can't find a solution. Sometimes my notebook starts up and everything works fine. However, after I turn it off and try to turn it on again, the motherboard starts, but the screen stays black. It seems like the notebook freezes and a green LED with a light bulb icon stays on.
If anyone has the service manual or any suggestions on how to fix this issue, I would greatly appreciate it.
Thanks in advance!

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
Hi everyone,
I have this strange behaviour with Acer Aspire E5-574-52RH, i5 6200U, intel graphics, DA0ZRWMB6G0 Rev G, model ZRW.

The black screen problem is random, maybe 5 out 10 times, laptop remains with the black screen, no image
Symptoms are:

Weird issue with this tv. Was streaming to the from a computer when it stopped working and the screen went black. Ever since then there has been. o image. Just a black screen. The audio works and yhe backlights do come on when it's powered on, it's just a black image. It presented like a backlight issue. So I finally got around to getting new backlights and a backlight tester. All of them test the same as the good backlights with the same voltages. There are no blinking lights. Just the white led at startup and when buttons on the remote are pressed signaling it's receiving from the remote....
