Just got a brand new Achieva Shimian QH270-Lite. First off, It doesn't have pretty much any control, no OSD or anything. Just Power button, brightness up and down buttons and on front, a led displaying orange on stand-by and blue when there is signal. The blue led "flicker" when signal is bad (ie. When using only DVI-D Single Link instead of Dual Link).
Hooked up to my machine and when Windows 7 started the monitor light turned from orange to blue and worked just fine. Then I just browsed my screen settings for a while and BAM! The screen just went black and blue light disappeared, as in no light at all, not even orange.
I immediately tried to fix it by using my old monitor and I removed my video card drivers and re-installed. No help from that. I have a ATI Radeon 5870 video card, so I borrowed a Nvidia Geforce 8800 GTS card from my brother. No dice. I tried to fiddle with the power cord, brick and DVI-D cable that came with the monitor. Didn't help either.
Right now, when I got no DVI-cable attached to the computer, the monitor shows orange light (stand-by?). When I plug the cable, orange light disappears and no blue light emerge as it did initially. Backlight turns on ok by the way and I can "crank it" up and down by pressing the buttons on the back of the monitor. I can see the monitor in screen settings page from Windows 7 and AMD CCC (and Nvidia control panel when I used Nvidia card) so EDID info is coming to my computer.
I visited at work and picked up another DVI-D dual-link cable from our stock for testing. The problem still stands. No picture, not even a hint of it.
My best bet is that maybe some internal cable is loose (LVDS?) but does anyone have any hints what I should look if it comes to opening the monitor?

But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
