Hello people, I'm new to this. I just found this site via a google search. My Kuro has been running perfectly until 3 days ago. I bought it in 2010. The AV dealer said it was his last one. Now, it will suddenly switch off after appx. 30 mins of use. Has anyone else experienced Red and Blue LED flashing, followed by two squares scrolling across the screen on their KRP-500A plasma display? I just wanted to know whether this was a normal occurrence and if it was an easy fix?
