The one on the right (when looking at the back head on) is green with P22LDE04 Rev4 on the board.
If anyone can help me get started in the right direction for getting this resolved, that would be wonderful.
Thanks

That pcb looks pretty much the same as the one in the original post. Nothing looks burnt or charred though. Are any of the capacitors (those 5 round objects, 4 black and 1 yellow) bulging or leaking? It seems that that there are many different versions of the green pcb (i think i've seen 4 different designs so far). In this case i am not sure if it is the pcb at fault or the power adaptor. Or both.

tehpsyc: Have you had any flickering after you got the new power adaptor?

No leaking/bulging that I can see. I did, by the way, after having this issue start, replace the power adapter from the one I got with the monitor that I had been using. Am now using this:

All seemed good for a few days, then it started up again.

Ok, that rules out the power brick as the cause of the problem. If there isn't any physical damage to be seen on the pcb there is no really telling if it's broken until you replace it. Your best bet is to ask the seller for a new pcb.

So real quick lemme explain the circumstances of how I got a new power brick. I actually ended up ordering a Shimian monitor as well tongue.gif I was tired of all the issues with the crossover and wanted to run dual 27"s anyway, so I went for it. I had been trying to use the Shimian's power brick on the monitor, which never had any flickering issues. However, when red-cap asked for a video of the flickering I switched back to the original. Oddly enough I haven't had any flickering since switching back either (only been using it for about a day though).

TLDR I haven't had any flickering issues using the new brick, but at the same time I only used it briefly and switched back to the original, and still haven't had any flickering issues.

Not to question you know what you're doing, but are you certain its a backlight flicker and not something else? also is it the whole monitor or just part, could actually be a bulb or something going bad. Most likely though its the green PCB which must not be perfect either frown.gif
post #3086 of 6483
Most definitely the whole monitor. I had similar thoughts you're having there and just to make sure did a full white screen and spot checked things with my eye. It's just as described from some other people in the thread. Starts out slowly and infrequently, but gradually gets worse - playing with the brightness levels on the monitor itself exacerbates the problem and accelerates the flickering. I can take a video when I get home from work as I don't have the unit accessible to me now.

Remember, my green PCB is different than the green PCB that's being described as the fixer so far - it's possible that getting the MStar one will solve my issue. I was an early adopter and got my monitor back in late March/early April so that would explain why I have the PCB given in the OP here. That also makes me think since it's been 6+ months that I'm going to be SOL when it comes to contacting my seller (dcsamsungmall) for a replacement board :\ Anyone want to go in on an order for the board x2 (since it looks like you can only order in pairs) from that channel someone posted earlier? I don't need two, but would be willing to split the cost with another person who needs one.

If anyone has any more thoughts, I'm open to any ideas that don't involve soldering, I'm determined to lick this thing! thumb.gif

Hi everyone.

A few weeks ago I took the plunge and ordered a crossover 27Q from eBay from "lightnspace". For £212.

After being delayed due to "tythoons" in SK and also their thanksgiving.....and also UK customs I reieved the monitor today.

First really annoying thing. I ordered the 27Q but they sent me the 27QD. the one with the built in speakers. Its doesnt look as good as the 27Q. (anyone had this happen to them?)

Also not really a big issue but I was expecting it to be one flat piece of glass like the apple screens. Not a plastic frame around it. But oh well. (does any of these Korean scressn existed as one flat piece like the apple displays?)

Anyway.

So today I plugged it in but it seems dead.

The red light comes on but thats it.

The PC does detect it though and sets the right res for it and thinks its there. But just no image.

Ive tried 2 different DVI-D cables. Tried both ports on my card (ATI 6850), tried using an active DP to DVI adapter. Tried booting with just the crossover screen plugged in, using both cables and both ports.

The green light on the power brick is solid.

The red power light on the screen never changes. So maybe the screen is stuck in standby or something as I thought that if it was a backlight issue the light would be a green or blue as if the screen was fully on? (unless the red light means its properly on?)

Im not to sure what to do now.

Any one else had this issue?

I've read sometime in the past month on here of someone getting the wrong model as well. The one flat piece of tempered glass isn't available on the korean models, that I know of, you can get the tempered glass versions but they will still have a bezel lip around the screen itself, it'll give feeling of the ACD (Someone correct me on that if I'm wrong). Blue means properly on when getting a signal also. Sounds like either software issue on CCC or something wrong with the main PCB in the monitor. Others here will elaborate more than I can with the issue as I've seen a post like this somewhere in the past, try 20+ pages back and you can read up on what others have done.

binarysmacker,

I also ordered a pair of 27q's from "lightnspace", I had read that he had a habbit of sending out the wrong monitors so I made sure I emailed him before hand letting him know that I expected the 27q and made sure that he promised they would be the correct model.

I am also in the UK but mine are still stuck in customs. I am awaiting a letter to tell me how much they're charging me, what did you pay on yours?

As soon as I have them I will let you know what I have received and if they're in good nick!

Cheers,
post #3090 of 6483
Hey,

It was £34 I had to pay. It was stuck in customs just over a week. EMS changed from "invalid invoice" to "missing invoice" but apparently just ignore the EMS side of things once its in the UK. It updated twice while it was in the UK but when I called customs they told me my parcel hadn't even been looked at yet!

Anyway, the second it moved out of custom to parcel force I just rang them up to pay the charge. I didnt bother waiting for the letter.

The screen came today, along with the charges letter! ha.

Its just so weird how windows detects the monitor, detects its res but the screen says black with the red light as if its not plugged in.

I know this as im running a second screen at the same time. Incase that was the issue I tried booting several times just with the crossover. No dice!

I found a thread a few pages back, someone having the same issue but it was because they had it in the wrong DVI port. Ive tried both :/
