I bought a new Crossover and from day 1 its been having this strange issue where the monitor will turn on, with a functioning backlight, but the display will stay blank. It doesn't do this all the time, if the monitor has been off for a few hours and is turned on in works immediately as it should (most of the time anyway). Once its working, it has no problems (doesn't ever turn off or go blank). If the monitor goes to sleep, the problem returns. This originally led me to believe it was some sort of weird temperature issue. However, I've found that when the monitor is not working ,if I leave it on sitting at the blank screen (backlight on) for about 10-15 minutes, it will spontaneously start working, after which point its fine until power cycled. If I power cycle the monitor it returns to the blank state for another 10-15 minutes.
I had contacted my seller who initially misunderstood my problem for the backlight issue and sent me a new LCD controller. I installed this anyway just cause I had it, to see if maybe it would fix it, which it did not. I was then sent a replacement main PCB (the largest PCB located in the center) which I was hopeful would resolve the issue. Unfortunately however, this did not fix my problem. So now I'm essentially out of easily replaceable parts (at least that I can think of) and I'm wondering if anyone with more technical knowledge could suggest what's going on or why it takes 10 minutes for my monitor to become active, yet works immediately on a cold start.
Just to confirm things I've tried:
I've tried 3 different power supplies, and 3 different DVI cables (I own another Crossover that works fine)
I've swapped ports
I've tried the monitor on my roommates computer (same issue)
My other Crossover works fine, so I don't think its my computer. I'm running a 7970. My roommate is running a GTX 560, so its not an issue of a specific videocard either.
I'm at a complete loss, and I suspect I'll have to do an exchange. However, if I can avoid an exchange it would be much preferred.
Thanks in advance for your input.
