CrossOver 27Q LED/LED-P, 27M LED, & 2720MDP GOLD LED Monitor Club - Page 438

post #4371 of 6485
Well, after 6 months, it seems like I'm starting to have issues with my 27Q. The screen flickers for a while when it's first turned on, then the picture just goes black. The blue light stays on, which seems to indicate that it's receiving a signal, but the backlight is off and it doesn't display anything.
Also, disconnecting and reconnecting the DVI cable brings the picture back for a little while (less than 30 seconds usually), but it still flickers, and then goes out. Turining the monitor on and off does the same.
Has anyone else had an issue like this? Could it be the power supply (which would be easy to replace)?

Edit: Turned off the monitor for about 10 minutes, then turned it back on. Seems to be alright now, though I'm still a little worried about what caused it in the first place.

sounds like loose connection somewhere, but keep an eye on it if it does it again

I BELIEVE (don't quote me on this though) that the 1600p HDMI standard is 1.4a , which also has the bandwidth for 3d applications too. I think.

I do believe it's a different cable layout though, so a regular "HDMI" cable isn't going to work, it'd require a 1.4a cable.

correct except there is no such thing as 1.4 anymore. it's just hdmi or high speed hdmi. any current hdmi cable you buy is "1.4" just not called that anymore because it was confusing hell out of people

if you have never used an ips monitor, especially at 2560 without AG, it will blow your socks off. i actually went through some sort of withdrawal until i found my specific issue with mine.i love my crossover, it is totally awesome. enjoy!

I don't know, how would I tell? The serial number on the back starts with 201206, so I assume that means it was produced in June 2012.

i'm pretty sure it's that, if it was produced in june, you might have the blue pcb for the led lights that causes the backlight to be off due to burnt out mosfets.

I'm nearly ready to pull the trigger. Can I get a little encouragement? Or can someone tell me I am looking at the best option out there if I need no features? I have OCD in many areas. Making the best decision out of the given alternatives is one of them. Then I just hope the panel has no defects, dead pixels, or abnormal backlight bleed.

Edit: Am I going crazy, or are these selling cheaper than the catleaps right now?

Also, what is this Crossover 27QD?

Great...
That doesn't really explain why it would flicker and then start working again, though, would it? It seems like it'd just up and die once the mosfets die. Is there any way to purchase a new PCB?
