Search this thread for comments on the blue and green PCB. There's also pictures, making it easier for you to compare your problem to others that have been reported.
Thank you so much! (you and everyone else giving their input). In the end I "solved" it myself! (so proud : P ). It was (apparently) a problem with the connection between the panel and the main board. I unplugged and replugged the cable and VOILA.I have a green PCB. For those having the same problem with their Crossovers, I'm not saying doing what I just did will solve your problem if you had the same issue I did (flashing LED and no image) but it's certainly worth a shot!
BTW: opening this up is reaaaaaaally easy if you are careful going at it. If you have any questions about I'll be more than glad to give ye a hand! : )
P.S: I hope this monitor lasts me quite a while, I really love the image quality : )
