Achieva Shimian Monitor Club - Page 298

post #2971 of 3508
Its a crapshoot everyone knows that or should. If you got the older glass ones they could have came with a fair bit of dust underneath. Any of them you buy there is a risk for dead pixels, backlight bleed, or the colors being slightly off. Sometimes they come with cold solder joints, and the signal won't output to the monitor properly though. If you get lucky quality will be as good as similar models by Dell. They are still A- panels so they still would be a bit worse but not by much. When you consider price if you got a good one it is a way better deal than a dell by far. Problem is you can get a bad one. Most people get good ones, the problem is if you don't they have no real warranty.

Well said.

If anything, go buy it using an American Express card or some other card that has good buyer protection benefits.

I can't believe it. I get peace with that I won't have a real IPSB model and I want to order the IPSI, but looks like its get out of stock everywhere. mad.gif

Only greensum said he can send one, for $639.9... for SIX HUNDRED AND FOURTY?! Seriously? biggrin.gif
Plus: He is also raised the pixel faulty policy to 2 dead on center and 20(!!!) dead on sides is okay.... It must be a joke... biggrin.gif

Looks like somebody, somewhere doesn't want me to buy an Achieva monitor

Hi everyone,

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)

Thank you."

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?

uzuzulla,

Judging by the description of the problem is either in the socket driver board, or contact LED illumination of the matrix itself. The second case is much worse.
Lights made ​​six vertical LED array, 3 left and 3 right. In my monitor driver has 2 channels, the first channel is connected to an even line, and 2 -1 to even.
If contact is lost one of the part of the driver, then one half of the screen will be illuminated by 2 LED array, and the other - the one LED array, so there is a different brightness halves.

i take it - much worse as in barely fixable?

it is less likely, because it would have been a defect matrix LM270WQ1.
In this case it is necessary to disassemble the matrix, line highlighting it should be located at the bottom.
But I do not do it.

Well, i welcome myself to the club. On Wednesday jan.30th i recieved my new achieva shimian qh270-lite that i ordered from green-sum on ebay.

Beautiful, love it, had the timescapes 1440p video available to watch as well, friends and i are pretty impressed by the image quality.

My issue is as follows though. I ordered a "pixel perfect" version for $389, and low and behold, there is one single dead black pixel on the screen, bottom right about 3 inches up and 2 inches from the right, took me about 2 hours to notice it, but its there.

Black light bleeding, a small area upper right at the top about 1.5 inches wide and .5 inch deep, not too big of a deal, only noticeable on a blacked out screen, im not too concerned with it.

So what do you guys think i should do? How does this work? Is it likely that i will have to pay to return the monitor? Do i risk getting a worse monitor or worse back light bleeding or other issues? Greensum is the seller, whom i reserched before hand as being a fairly reliable and popular seller of these catleap/shimian/etc.

Its hard reading through all these pages and im noticing some are having to pay for return shipping, some dont, other problems as well. Thanks yall.

I'm receiving mine from green sum too this next week. You made me quite wary about it, but well, let's see.
If you have problems the best you can do is to contact the seller directly to see what he offers you.
