a plus end and a minus end. If somebody installs them backwards ( a common mistake ) they might work fine for a while, and suddenly give up. Violently. I've seen the little ones go *pop*, and the
innards spit out, just like confetti. The big ones... Let's just say you don't want to be near a big one when it pops.

Maybe you can get your vendor to email you a photo of that board from a good monitor?

Got a response back from AW.

Hi

Sorry for the inconvenience.
Have you removed the paneling to see if there's something blown?
Will you check if the board is defective?
If you take off the back panel of the monitor to see that a MOSFET on the LED Driver board had burned out like these photos?

If there is no burned mark, I think connector board is defective when it's deliverd.


Sincerely

I am work right now, so I was only able to click on the first 2 links. The last 2 are blocked by our proxy.

Took apart the monitor last night and after looking at only the first 2 pics, everything seems fine. If anyone could please go to the last 2 links and post the pics they want me to see, I would really appreciate it! Thanks!

Well I got my Crossover today. Only 1 stuck/dead pixel, which is perfectly acceptable for me. However, when I went to turn my PC on a second time and loaded into Windows my monitor went all ASDFGERGHFGHDRTJGHNCVNSETYHRGHDFGH and had a bunch of vertical discoloration across the entire display... Restarted, seems fine. Any ideas, or should I not worry about it?

Mine did the same thing. I would contact AW! I'm still waiting to hear from them on my monitor. It could happen again. I tried restarting like you did and that did nothing. You can see the picture I posted back a few posts. It sounds just like what you are describing. Did you order yours from AW???

If I can reproduce the problem I'll gladly post pictures. I'll look back and see if it's the same. But no, I ordered mine from Green-Sum.

Edit : No mine didn't that. It was MUCH worse than that, and I mean a LOT worse. But it still works.

Loving my Crossover so far! I'm just calibrating it with spyderpro and it has asked me what backlight the monitor is - Fluorescent CCFL, White LED or RGB LED. Can anyone tell me which one it is for these screens?

Thanks

I just wanted to update my experiences with the seller "bigclothcraft". They provided excellent customer service for the monitor whine issue I was experiencing. They shipped out another monitor PCB upon request, which solved the issue.

Just wanted to throw it out there, bigclothcraft is a great seller, and I may purchase with them again if I get another Crossover. Also my monitor was advertised as "perfect pixel" and that description was accurate. Other than the monitor whine, my unit arrived with zero dead pixels, zero bright pixels, and no obvious or glaring tint/color/uniformity issues.
