As most people know by now, leaving your Wii in standby mode for a long time may cause the GPU to overheat, and leave you with dark, ugly pixelation. I had this issue and sent it in for repairs, and it's back now, good as new. But while I was on the phone, the Nintendo guy didn't seem to be well-informed about the issue. He kept constantly saying, "Well...the Wii is designed to be left in standby mode...the Wii is the best thing since sliced bread..." I thought this would have been a well-known problem and setting up repairs shouldn't have taken more than 2 minutes. Anyways, now that I have it back, I'm debating whether I should leave it in standby mode or not. I've heard that it could just be that my Wii was old or faulty or something, and it should be fixed now. However, they merely replaced my damaged components; they didn't send me a brand new console. So it could still be faulty. Has Nintendo released a firmware update that fixed this overheating issue?
