I am wanting to repurpose an old monitor of my nieces that stopped functioning properly.
The problem the monitor is having is, when you turn it on, the indicator LED turns green and it will display the company logo "ACER" for about half a second before going black. Still with a green LED, after about 2-3 seconds of darkness, it displays a grey rectangle in the center of the screen for what seems like 1/16th of a second before returning to black and the indicator LED changing from green to amber.
Pressing the power button at this point will repeat above.
By repeating this process about a dozen or more times, the grey box has nothing written in it. (it goes by so quickly I had to watch for it a few times to be sure)
Monitor Menu buttons do not display anything on monitor.
Changed DVI cables.
Changes power cables.
Signal is coming from my DVI/HDMI sources (do not have a VGA source to see if it will accept that signal)
tried HDMI-DVI converter
Opened the back of it thinking maybe bad capacitors, but cannot find any leaky or bulging caps.
Tried it on Raspberry Pi / 3 PC's / X-Box 360 (thought maybe the different resolutions and display output types may trigger something in the monitor.. I had a HDMI capture card that wouldn't be recognized by my graphics card as a monitor, but captured the X-Box fine. long story short. something was wrong with the capture cards HDMI and thought it couldn't hurt to try the idea on this monitor).
Hopefully someone has an idea.. that will send me in the right direction. Because I'm all out of them.
