I have two Samsungs for many years - still OK. Few years ago I bought larger TV - a 65" Sony and it is great TV (XBR-65X900F). In addition it is based on Android OS, so I can install applications and it updates firmware often.
Is it possible that your TVs are dying because of power surges (power line or cable)?
