Yeah, all I was getting is a blank screen and the backlight was blinking on and off kind of intermittently.

Any luck 101589dpm?
Their is a solutions list to black screens on the first page of the forum. Best of luck:)

Nope, no luck yet. I've reseated all the cables inside and tested the power brick (putting out 24.3V). One curious thing is that the board on the panel might be the B version... I don't know if that is possible, but it appears to have two connection slots on it like the pictures of the other version. But the capacitor (?) has the italicized 220 like the C version (going by this photo). I don't know if that possibly has something to do with it. I'm going to try it with a different source once I can get my hands on something, but after that I'm stumped.

Edit: The symptoms are the same... the backlight is just flashing on and off intermittently. No image whatsoever.

Two blue/white to the panel and then one other with the clip type connection? (Based on this teardown). Because all I've got is one blue/white from the board to the panel and the other white one.... there's nothing coming out of the "socket" where the DVI input is. I've included a photo below.
Mine is the tempered glass, single DVI input, no audio version (Q270SE).

That is the correct wiring for 2C models.  The panel PCB is fed by the blue/white/black wires on the right.  The all black wires in the middle are to the front OSD (brightness, etc.).  The bottom white feed the LED.

Please take a photo of your panel PCB and an up close of the P/N (on the left-hand side of the that panel).  That will tell us if it is in fact a 2B panel.  If it is your panel will not work since the DVI PCB will not be outputting what the Panel PCB needs to operate (at least with out some sort of rewire we haven't tried yet.

Here's the panel board. I guess it is the 2C, but there's a connection there that doesn't appear to be in the comparison photo.

Are you 100% they were DVI-D and not just DVI?

How do you guys clean the screen of the monitor (non-tempered)? I use a lint-free cloth and dampen it with water a little bit. When I try to clean it, it made it worse and left smudges that can be seen when the monitor is off.


Edit: I added a bit more water and clean it again. Then immediately go over it with another dry lint-free cloth. That seems better than before (in removing smudges).

Well it isn't a 2B PCB, but a whole new one I haven't seen before.  Just makes me more convinced these guys are mixing and matching boards and parts to get the panels up and running.  Not sure what that connection is for - you should be good with the standard plug ins (unless that panel PCB does require something at that connector of course.)
