Honda Odyssey 2004 rb1 built in screen stopped working?

[Tumee Erdenee]

I recently bought this car from Japan. Unfortunately the screen just went blank. Screen does light up upon startup but nothing loads. No music from harddrive, no fm, nothing. Not even the clock works. When this problem first started, there was ""system boot" and bunch of Japanese words" notification some sort, then it loads, then after that system works fine for 5-10 minutes, then it goes blank again (music just stopped playing). Now, nothing loads. Screen is always blank.
What seems to be the problem?
Is there a way to change the built in screen, or the whole dvd system with double din after market reciever? (just don't need it since everything is in japan)
