No video signal on my monitor. Every time I boot the computer, green lcd's come on for a while and then turn the power lcd to yellow. Nothing happens after that.
I checked the followings:
- Connected another monitor and worked, it means the cpu and the video card work fine.
- Checked the input power and it reads 120V AC, it means the power supply is fine.
- Checked the horizontal output transistor (HOT) and it seems to be fine.
I am now suspecting the monitor is on Sleep Mode and I am unable to bring it back. This monitor was working fine without any problems. Before I went holidays, I unplugged the CPU and I believe I forgot to unplug the monitor. When I came back from holidays, the monitor doesn't want to work for me.
I am taking this as a challenge to fix it. I need some advice from the experts. Please give me some clue.
