My other crossover, which after getting the LED PCB exchanged, has been working fine for about 6 months, and it too is missing that screw. I never lifted up the plate on that one t o check the LG boards however, but I suspect they all have that adhesive that can be a normal finding in electronics.

The symptoms of my screen don't quite sound the same as yours. Mine seems to be an issue with the monitor sending the actual display data to the panel. So far I've been able to get the monitor start in about 1/50 power cycles (3 successful starts so far) and once its started its fine and has no issues. But if let the computer sleep or power cycle the monitor the problem returns. The display is blanked out immediately upon restarting, with no picture ever displaying. The backlight and brightness adjustments work normally.
Thanks for your precise feedback.

Here's two more videos of my monitor fading out. The second one is a bit longish, but it features a Star Trek video to compensate for that. smile.gif Unfortunately, most of the time it is blacked out frown.gif

Does anyone of you blackout guys also have this quick fade out effect?

See the pictures in my posts. Mine fades out slowly instead of quickly though.

that's how it was for me when I got a power supply on one of my 3 that died after 20mins. next day air from korea... insane

Yeah, their shipping is unreal!

Well I'm back after a few months of no issues because I decided to buy another Crossover. I was originally very active on this thread when we were all trying to figure out what was going on with the backlight dying and the PCB variations that were responsible. I thought it would be great to do dual Crossovers, so I went for it. Within an hour of using my new monitor, the screen went black and rendered no display. My computer still thinks its working (the monitor is detected) and the back light is still on (so not the famous back light PCB burnout issue that I had with my first Crossover) but a whole new problem. I've contacted my seller and I must say I am extremely devastated to have this happen again. I have tried the following options:

3 DVI cables
3 different power supplies (the one it came with, the one my other crossover came with, and one from a Shimian that was exactly the same)
Both DVI ports on my computer (Radeon 7970, one DVI port and one mini-displayport with the expensive adapter)
My roommates computer (GTX 560 Ti)

I had been running dual 27" IPS's for a while now, just one was a Shimian and one was a Crossover, and I really wanted to get a matching pair. So i had found someone to buy the Shimian and was going to do that swap. I only mention this because I want to verify that my setup is able to handle two of these panels without a problem. I suspect something is wrong with the primary PCB, the one where the connections are made, and will need to be replaced; but if anyone has any suggestions I can try while I wait at my seller's mercy yet again it would be greatly appreciated.

Also, to make the situation more confusing, I randomly tried firing it up again, power cycling it several times rapidly and it actually came on and was working after having been dead for a few hours, not to mention the first dozen or so attempts immediately preceding. So naturally I decided to cycle it one more time (it was living on borrowed time anyway) to see how it would behave, to which it returned to the blank screen with the back light on.

Well red-cap apparently will be sending me a new PCB. I've been trying to get them to clarify which PCB they are sending (since I'm afraid they might just send me the LED PCB again) but I suppose I should give them some more credit. However since the initial problem developed I have learned some more information.

It appears that the monitor struggles only after its been powered on for a period of time, requiring many (50+) power cycles before I can get a picture. This is why it seems to only happens after say, my computer has fallen asleep after an hour of use and I try to wake it up a few minutes later. However, if the monitor has been off for an hour or so, resulting in the monitor being off, and has had some time to cool down, (or at least that's what I suspect is wrong), it works first try. It always starts first thing in the morning, and if I turn everything off before I leave the house it seems to start right up when I return. I suspect its a heat related issue but was not able to identify any areas of heat damage on the PCB itself.

So the pictures would be here, just 1 day, 17 hours ago:

From what's discernible in the picture, this doesn't look like what's in my videos.
As for a description, you wrote:

So this left me rather clueless as to what bedevils your monitor, but I guess it's just difficult to convey without also showing a video for illustration.

I'm uploading a video right now as we type.

Edit : http://tinypic.com/r/2yyy3ph/6

Roughly a minute and thirty seconds long. I was trying to record and hold my daughter at the same time which she didn't like sitting still at the time, haha.

Just an update on my order of the 27Q LED-P

was packaged well, but has a big deep gouge on the screen itself!

I ordered mine from green-sum. I messaged him on eBay today to see how he will exchange this. No reply back yet.

Any tips on how I should handle this if I don't hear back within the next day?

The monitor looks amazing minus the dang gouge. It's deep and no way to fix it.
