The monitor in question, acer s230hl.
Here's the problem. About a year ago, I turned my computer off to move into an new apartment. When I set everything up, my other monitors turned on fine, but this one flashed on for a second then black screen. It went back and forth like this for about five minutes, then the acer logo came on and it went back to working normally. It appeared to do some sort of hard reset on itself.
When I moved into another place about a year later, it did the same thing, only this time, it took almost half an hour to start working again. This happened three or four more times over the next couple of years each time with an increased time of full picture, black screen, full picture, black screen, and so on.
Two days ago, my water cooling pump clogged and I had to flush it. The computer was off for about five hours. After I put everything back together and powered it up, same issue. I waited five hours this time, still pulsing. This time however, it would just flash the screen, no full picture. Flash, black, flash, black, etc. I figured it was the same problem so I left it and ran some errands. Five hours later, same thing. I left it over night, same thing. When I mess with the buttons (sometimes jamming the power or input button will get it to work) the light goes stable, and I get picture for a millisecond then back to blinking.
I spent 8 hours scouting the internet yesterday trying to find a cause to this weird problem and everything I was reading said power problem, so I dismantled it and got really confused. There's only one board here, and a few spread out caps. Not the traditional power board and display board, and it's much much smaller than the demos I was seeing online. Still, I looked at the caps and they weren't bulging. I reset the ribbon cable, made sure all connections were tight and correct, and still can't get it to work.
It's not an led problem, I see the picture fine for that millisecond before it goes back to pulsing. It's can't be cables because I've tried it in two different fix cards with hdmi, vga, dvi, serial, adaptors.
I'm at a loss. This is just another in a series of things in my life that are just broken down and I'm at my wits end. If I knew what was causing the problem I could easily fix it, but I can't even begin to find the problem. Please help!
