Alright guys, so I did more research and bought a AC adapter for it 12volts, 1.5A center positive but it won't work. I think I might have fried the AC adapter port when I was testing for the power a few years ago lol. (Sorry newb mistake, I jumped the gun) how do I fix my mistakes without having to buy another monitor?
Just checked, I believe my unit might be the Lilliput 619 and I checked the fuse, it doesn't seem blown. I put the multimeter on it, and I get -13.64 volts and 13.64 volts. (The 1A fuse near the barrel jack) Although on the other side where the barrel jack is soldered, the two grounds work, and one positive works. What is the other solder point? That doesn't seem to do anything.
I tested the ribbon with the 4 pins that connects to the LCD, and it's getting -12 volts. And the backlight wire as well.
