I recently replaced the mother board on my old Sharp Aquos LC-52D64U. When I had the back off it was clear that there was a lot of heat build up. The boards at the bottom were nice and tan and got darker moving up to almost coffee colored. So thinking heat was major contributor to failure. I have a Dish VIP722, Sony Blu-Ray, Wii, and Gateway LX6810 connected. The Dish box (even turned "off" it sends screen saver) and computer are constantly sending signal to the board. When the kids don't turn off Wii it's sending signal. Does the board process those signals even though that input is not selected? Or is even the heat of those electrons being fed into the board (even if not processed) detrimental? Would physically disconnecting all inputs ( or unplugging devices which would mean updating manually cause nighttime is when all that happens) increase the life of the electronics? Also considered putting fan on heat sink of processor. Or should I just consider myself lucky that I was able to fix a TV that was built in 2007 and enjoy the time that I get out of it without the extra hassle? What y'all think?
