Big Screen Mitsu's usually see 12-15 years with proper maintenance and also when you purchase a big screen Mistubishi gives you the option of upgrading your television throughout the years. For example: You buy a 2003 Mitsubishi Gold Big Screen and 3 years down the road some new feature that is astonishing comes out. For $150 Mitsubishi will sell you a chip that will upgrade your older television to have that feature so you don't have to go out and spend another $2,000 on a new TV. Damn.. Mitsubishi finally built something reliable =)
