i've just received my Shimian 270-lite from green-sum. I've orderer a "perfect-pixel" version and well, it is. There are no dead pixel's.
The problem is that left half of the display (esp. at the bottom) is about 2 times darker/dimmer then the right one. It's most notable, when i turn the brightnes down to the lowest limit.
I've noticed that if i "twist" the display on the sides a bit, or press at the lower bottom (not on the display, but the plastic frame), then the picture gets almost normal, at least not as ugly, at low brightness at pretty much ok at higher brightness levels. But then some time passes and it gets to it's "normal state". Also there is some kind of "blinking", i.e. the left area becomes darker/lighter, then again darker etc
I've also noticed that chaning brightness (going lowest, highest, lowest, highest) makes the pic gradually worse. For instance, i can press at the lower bottom of the display at the lowest brightness setting possible and "fix" it. If i do nothing it goes back to the original state in about 5 mins. If i go to the upper brightness level and back again, the left side becomes darker. Going up/down again, leads to even worse result. After about 4-5 repetitions i have the worst possible picture.
I've at work atm and dont have the pictures of the screen right now, but if anyone is interested i can post them.
As far as i understood this is not backlight bleeding, but i also understtod it may be fixed following the disassembly guide and adding extra screws / straightening the metal frame. Is that true?
I didn't do that yet, since i figured i will loose the oh so important warranty. I mailed green-sum (but did not open the e-bay case) about the problem and he answer about the following:
"Hello, this is Green-Sum, the eBay seller.
First of all, we are deeply sorry for your inconvenience. We will make our best efforts to support you.
Maybe the backlight of half of the monitor has a problem during shipping. We test every monitor right before we ship it. But the monitor does not work properly, it might be caused by internal shock during shipping.
Next, we need to contact the manufacturer for the issue. IN order
to do that,
you need to provide the
1) pictures of product showing the problem,
2) delivered box,
3) serial number located back side of the monitor.
And we need to receive them to our email address,
greensum_CSbuy2korea.com(NOT E-Bay which photo size is small)
It looks like a proper answer, but i'am a bit worrying about opening the ebay case and selling the display back from germany to korea.
Has anyone already faced similar problems?
