My monitor is V7 d22w12. Older monitor yes, worked fine for long time; it started having the following issue (when I encounter the issue, it's usually after like when I shut of pc, go to bed and the next day want to use computer and boot it for first time of the day. Seems to be happening more frequently then before though I'm not sure):
When the issue is encountered, the monitor power LED light would blink green/orange with screen staying black which happens during the bootup of computer, sometimes I unplug/replug data cable and monitor display comes alive and normal again (maybe have to do that a few times to get it to work), sometimes I unplug power cable then data cable to monitor and finally it comes back alive. Or sometimes I just am in the process of tightening the screws of the data cable to monitor and display picture appears as you'd expect.
But it seems that if I play around a bit, get monitor working again, the issue doesn't happen for rest of the time I use my computer. So when works it appears to be normal and happy and not causing trouble.
What is the blinking LED light trying to tell me? Something really wrong with monitor like some internal components going bad or just a simple fix? Yes, computer itself is perfectly fine.
Hope this makes any sense; don't want to replace monitor if at all possible.
Thank you
