Yes, we hate it when our favorite TVs lose their smoke; sometimes it's like losing a friend. (Smoke and mirrors ... I'm told once a piece of electronics lose its smoke, the magic is gone.)
If you are looking for suggestions rather than consolation, you might consider posting your message over in http://www.avsforum.com/f/63/rear-projection-units, which seems like it might be a better fit for your type of TV.
My very humble setup:
|Man Cave:||Vizio E500i-A1 "Smart TV" (50-in 1080p 120Hz LED/LCD, has Netflix app.), Blu-ray players (Sony BDP-S3100, old LG BD390), Roku (the original model: N1000), PC (Windows 7), Comcast Internet (25Mbps/5Mbps).|
|Bedroom:||LG 32LV3400-UA TV (32-in 768p 60Hz LED/LCD), HD DVR (Motorola RNG200N), Xfinity Comcast cable (Digital Starter Package), DVD/VHS player.|
Haha, haven't heard that phrase in a while! Was common when I was an active electrical engineer, the smoke coming out when a part fried. I could have sworn I once saw a tiny mushroom cloud come out the top of an electrolytic cap when I accidentally hooked up the power reverse polarity.
