I'm having an issue with my Catleap Q270 which just arrived.
It came with the Korean power adapter for the DC converter, which was to be expected. I plugged in a US power cable, and set up my monitor. However, the LED light on the monitor and the power brick just keep blinking red.
If I unplug everything, and just plug the brick into AC (and not into the monitor), the brick LED lights up green. However, once I plug in the DC plug to the monitor, the monitor and the brick start blinking red. It doesn't matter if the DVI cable is plugged in.
I've tried it with 2 different US power cords; with the DVI cable they sent and one of my own, and on the two different DVI outputs of my video card between various stages of PC being on/off/rebooted. No different - the monitor's display never lights up at all.
It is worth nothing that Windows 7 notices that the monitor is attached (I have a second monitor hooked up which allows me to change display settings to troubleshoot), and Windows correctly identifies the Catleap's native resolution.
Any ideas? Is it an issue with the DC adapter, or the monitor? The DC adapter is a Welltronics WTS-2405W. IT says input is 110-240V AC, 50/60Hz, 1.5A - which should be fine. Output is labeled as 24V DC, 5.0A.
Here are some pictures of the adapter:
