hi I accidently dropped my monitor whilest carrying it down very steep stairs. After that it now has vertical lines across the screen. Also there's a part of the screen that looks darker. When you first turn on the monitor this area is small but then it goes bigger. Is this repairable? Is it likely that I would have to replace the lcd module itself? It's a good few years old. I suspect it also has an issue with the light source as well because sometimes it has trouble lighting up the screen. But generally as it heats up it's brighter. To be honest I'm getting a new one but am just curious. Also I've always had an interest in electronics. Also is repairing this potientially dangerous? It's only 12V and at less than 5amps.
