I own a Mitsubishi 50" RPTV, 4:3 television. It's about 4yrs. old now and i'm wondering what the average life on these TV's is, just in terms of life spans, not bulbs. How long have most people with Mitsubishi TV's had them for? I know they are an awesome television but most manufacturers these days don't put much quality or pride in them so they end up breaking after about 5 yrs. or so... I just pray mine will last at least 3 more yrs.
