U2410, MacBook Pro, blinks

Question

Hi everyone, im new here in the forums.  I just bought a Dell u2410 monitor and I have it attached to my Macbook pro laptop using DVI-DVI cable. My problem is that the display of the monitor 'blinks' frequently.  What i mean is that the power of the monitor is turned on ( blue color ), no power save mode messages or any from the monitor. power doesn't turn orange. It just turns black for 1 second and then turns normal again.   I have a mouse and keyboard attached to the 2 USB ports at the back, and when the monitor turns black, i can still type and move my mouse.  This happens frequently. But sometimes, it doesn't happen at all. sometimes it blinks once every 10 mins. sometimes it blinks a LOT enough to annoy me.  I have tried using DVI-VGA(monitor) and the same thing is happening. I tried removing my external mouse,keyboard. same thing. it is the same whether my macbook pro's display is turned on or off( clamshell mode ).  I am using a 2007 Macbook pro 15-inch, 2.2Ghz, 2GB ddr2 ram, NVIDIA 8600M GT. I run the macbook pro without the batteries. Please help   Additional Info/Updates:  I tried turning off the laptop with the monitor on. With that i can only play with the OSD using touch. anyway i noticed that even without the laptop, the monitor was still blinking. i can play with the OSD even when it blinks. As of this moment, after going out and turning off my monitor, i go home and turn it on again. this time, the screen is completely blank. the power button is on. I can play with the touch OSD but cannot see it. I can say because I see the lights turning on for the OSD touch. I cannot also see the self-test provided. but i know its working because the touch blue lights are reacting I have tried connecting the monitor to a PC via DVI -> VGA and VGA -> VGA to no avail. the monitor stays on with the blue light, but no picture whatsoever. incidentally, i noticed that during when my monitor was still showing picture, the vents at the back were warm. now i have tried turning it on for more than 10 mins and its not getting warm. I don't smell anything burning. i checked the fuse on the chord and it looks like it hasn't blown.  Also both windows and mac are able to detect the monitor and change its resolution. I can even hover my mouse over to my u2410 though i cannot see it.  My 4 USB ports are also working when i attached the upstream/downstream to my pc/laptop

Note =Dell did not test/validate this U2410 on the proprietary Apple operating system or hardware.* The U2410 driver page only shows Windows drivers* The U2410 User's Guide only mentions Windows* Your best chance of getting assistance with non-supported Apple products on our U2410 is the Apple ForumSelf-Test =* Turn the U2410 off* Disconnect the U2410 from the PC* Disconnect all other devices plugged into the U2410 so the only thing plugged in is the U2410 power cord* Turn the U2410 on. The Self Test should appear. Does it stay on?

Get it replaced if still under warranty.

yup I did that too. Even the self-test can't be seen.   I tried asking the local repairmen here, they mentioned something about the inverter.  any other ideas?
