I've received for free this monitor in good cosmetic conditions, defect never seen be me, it works but on the normal video output there is a big central fleck of pixels of various colors, and 2/3 irregular width thin stripes that comes down from the top, the fleck areas are like chess pattern (or diagonal lines), screen is not cracked, to me seems like a liquid is come inside from the top. Since in this period i don't have time to waste into impossible tasks, i ask, there's a chance that by separating various panels of the lcd screen and maybe clean the dirt i can fix it? It is not a video input card problem, i have swapped it with a known good one. MUCH THANKS and BYE. (As always sorry 4 my English, i can't import pictures easily with my phone 'cause my bluetooth stack is buggy)
