(I'm surprised there isn't a board dedicated to rear projection TVs, now that I think about it.)

This is a weird one. I LOVE this TV, I saved it from the curb many years ago when it needed its DMD replaced (did it myself) and it's been in pretty much constant use since. It's just turned 16 years old and I recently had the blue LED go out, so I went ahead and replaced them all. The issue is unrelated. This ONLY happens on the component video inputs, NOT over HDMI. When I am playing games or watching TV and a scene happens that makes most or all of the screen white or very bright (white screen, flashes, explosions, etc.) the TV will just...drop the signal. I temporarily lose video and audio until the onscreen image darkens back down again. It's as if someone changed the video input (OSD appears briefly once the set regains its footing). If the screen remains bright for long enough, I actually get the 'Mode Not Supported' dialog...very puzzling. I didn't think that would display unless I'd connected something with a resolution the TV couldn't handle? (E.g. feeding a 4K/2160p signal into it) The Wii U game console I have plugged into the component jacks is outputting 1080p and otherwise is just fine, no issues unless and until the screen suddenly gets bright. I'd previously been using the same game console on an HDMI input and had no issues. I moved it to component because I needed the last available HDMI port for a new Roku Express streaming stick.

Anyone have any thoughts on why this could be happening? If needed, I can try and reproduce it and video it.
