Made the mistake of plugging in a 19v power adapter into a 12v monitor. Now the monitor does a power cycle and never fully turns on. My question is how i might go about fixing the issue.
I took a picture of the board - View: https://imgur.com/a/6zLHJYV
The monitor is a 'chinese' brand - Prism. model m27eq. I have another identical monitor that works fine. When I plug in the monitor, the standby light turns blue(on) for about 2 seconds, switches to red(standby) for about 1 second, and then completely off. The status led on the external power brick also turns off when the monitor does which leads me to believe maybe there is a bad capacitor? I've tested the power brick with my working monitor and there is no issue.
None of the capacitors visually look blown/puffing and i wasn't able to find a fuse on the drive board so I'm at a loss of where to begin. Does the power cycling of the monitor and power brick led's indicate a bad capacitor or what would you think? All of the videos I see online about repairing LCD monitors show replacing caps on the power board but mine doesn't have a separate power board. The display, housing, and stand are in great condition so I'd love to get this baby back up and running if possible.
Any help or ideas would be greatly appreciated!
