I request inverter Board from manufacturer.
They prepare to make shipment.
When I receive board, I will send it by express shipping service.

Is this the part I need for my backlight flickering, "image going to black whilst monitor light stays blue" problems?
I've just replied to his email and sent him a picture of the LED driver board asking him if he will be sending me the green one, hopefully he will and hopefully it fixes my problems.

Did you inspect the LED driver board and confirm that it is REV 00? by digitalwave(blue PCB with large coil) If it is failing there should be visual damage at the mosfet and brownish discoloration on the back of the PCB. I would suggest everyone inspect their LED driver board for the REV 00. If you do have the REV 00 I highly suggest you contact your seller and have them ship you the new REV (green PCB). Even if the LED driver board is not failing yet it will eventually fail.

Not sure why BCC is calling it a inverter. Big difference from inverter to LED driver. Inverters input DC then convert the voltage to output AC for the CCFL bulbs.

Yep, I've just gone and checked it now and I do indeed have the blue LED driver/inverter board which is rev00.

You can see in the pictures below that the mosfet is damaged and there is discolouration on the areas around and behind the mosfet.

I don't think I've seen a guide on how to replace any parts of the monitor so far so I'll make a simple picture tutorial.

Guide to opening the Crossover 27Q monitor and replacing parts

Firstly, unscrew two screws at the bottom and 6 on each side on the back of the monitor. The 7 screws in the centre can remain there (left and right 2 hold the side "flaps" and the bottom 3 hold the monitor i/o plate).



Once you've done that the back "shell" of the monitor should be free from the screen. The back shell has the LCD driver/inverter board on the left and another board in the middle. (Looking at it from the back, not from the front)

Be very careful as you lift the back shell up as there are two wires connected to the panel. One is at the top and one is on the left side of the monitor, going into the LCD driver/inverter board. You need to carefully disconnect these two cables.

Here is the panel itself:



The boards screwed to the back shell:



Rev 00 Digital Wave LED Driver/Inverter board:



You can see that the mosfet is damaged and the area around it is discoloured in my photo. Here's a picture of more obvious discolouration on the back:



When you put the monitor back together, make sure the little light diffusing plastic thing is placed back into position:



I didn't realise mine fell out and I didn't feel like going through all the screws again so I'll put it back in when the replacement boards arrives.

Bought the 27QD fro maccessorieswhole Sunday at like 2am. It tried to get here Tuesday around 2pm-- Twice I wasn't able to answer the door, so I will get it tomorrow. Still, amazing how fast they ship it, and it was free shipping! $339 shipped!

Hoping I don't get any dead pixels, but this would be my third monitor. I want to try nvidia Surround, but it's a bit of a doozy. I have an Acer HN274HBbmiiid (1080p), Auria EQ276W (1440p) and now this. Just to try Surround, for best experience, I will run it at 5760 x 1080. It's more to test if the bezels will irk me. If it does, I'll sell my Acer and go dual monitor with the Auria and the Crossover. Definitely recommend dual monitor for those who want efficiency and are not already using!

Can I use this guide to disassemble my 2730mdp?? I want to check if I got the blue or green pcb.

Ah, I forgot to mention that that was for the 27Q only. The other models have a different housing from what I can see.

You actually don't have to take the whole back cover off. You should be able to take the 4 screws out for the LED driver access panel. Just be careful to not pull the panel up too far because there are two wiring connections. Also it's just a LED driver board not a inverter. Inverter is very different.

It should be almost identical. Monitors are very easy to take apart. Not sure if the LED driver board will be the same since your panels brightness is 380cd and the 27Q is 420cd but it only takes a few minutes to check.

Well it didn't work for me, I obviously tried that first. I would have thought that with the way they designed it I could just open the left and right flaps but I tried on both sides and they both wouldn't come out.

I have no idea if it's an inverter board or what to be honest. The board itself says it's a LED driver board but BCC said he's sending me an inverter board. I linked him my images though to make sure he's sending me the right board and he said he is sending me an inverter board which will solve the problems I described... lol.

Got my monitor, and it's great... except I have a LOT of light bleeding! There are four big "splotches" of light bleed; two right next to each other a little right off center, and one on each off corner of the bottom. What's accessorieswhole return/exchange policy, in anyone's experience?
post #5810 of 6483
Hello guys, I am having the same problem with the so called inverter board. My board has some serious discolor. Can you please tell me where can I order the board? Since my seller doesn't want to honor the warranty he promised. Thank you very much!! Also,can you guys give me the picture of your AC adapter? Mine is Input 110-240v~50/60Hz, 1.5A. Output: 24v----5.0A. Could it be the cause of my problem?
