Hi guys. My cab has the mentioned monitor and it has started to act up. When I turn the cab on and the picture appears, the picture is usually a bit to the right. This goes away in about 10 seconds. In addition to that, from time to time, the screen jumps around from top to bottom (looking from horizontal angle) and then gets back to normal. This has been happening only for two days now, but I'd rather be early with this, than late.. Where should I start, what should I check first? Kind of new with monitors, but not with electronics, so I'm all ears. And yeah, I've read the instructions for how to discharge a monitor (a few times), but I've not done it yet. Thanks!
