do not even try or think of opening your cintiq or unscrewing it, even if you are a professional coz it'll void your warranty.
a damaged dc jack have forced me to open my precious wacom cintiq companion. I deliberately opened it and will suffer the consequence of voiding my warranty and regardless of Wacom's word to replace all the cintiqs with the dc jack problem. My case was quite simple, Wacom is made for mobility, and I do travel a lot but in jeepneys or trucks here in the Philippines, I seldom charge it when im outdoors only when I am at home and my cintiq companion is steady at my desk. I'm the type of person who grows an attaachment of my device especially devices that is use in my artworks. I have spent a month looking for solutions and usually finds people on forums trying to get the replacement device for defective dc jacks and most guys said it's the 3rd-4th replacement?!? oh goodness gracious... I could never replace my cintiq easily, so here I am trembling with fear and have finally dared to OPEN :,( my device. I'm going to write to Wacom about it and will likely tell you my own fix-it for this problem. I also found out about the dc jack's pin is ridiculously thin even my mini phone has bigger size for charging compared.
But don't take me wrong guys, rather than writing some complains to Wacom on how its really expensive and breakable, I gambled my warranty to look for a fast solution rather than giving it back to them, I'm on a tight deadline with clients and I cant wait even for a month and I'm here in the Philippines and I am really scared if they fall into the hand of the "wrong guy" if you know what I mean, I do love my cintiq companion, no lag or any issues here, since Philippines is a sunny country, the only problem is the exhaust coz it burns when you wear shorts and place it on your lap, I'm left handed so I am force to flip my device so I can use the express keys on my right hand as well, other than that, the CINTIQ COMPANION is still the best tool for artist-on-the-go or for cubicle cramped up designer to stretch that skinny legs outdoors. As far as googling someone who had opened it, I guess I'm still the 2nd guys to have sucessfully opened it and didnt do much damaged or worsen it (correct me if im wrong about that statement. So for the guys who are planning to buy the companion, just check everything even them tiny holes ok? and get some protection sheet or somethin' i dunno, if you use it everyday then you should consider protecting the screen. We'll ask away or enjoy the New Year party party! hehe.
