You must of bought one of the last ones for sale? I got two CRT TVs from Walmart on close-out when they were discontinued in 2009 by most sellers. MY Walmart CRT TVs are both analog. They still work fine but we did have trouble with one of the analog conversion boxes.
I don't know of any "bad" TVs out there now in regard to reliability. Some have better tuners and sound then others. Many low priced ones around that are fine. Sceptre is probabably the best bang for the buck if you want an LCD. I bought our daughter a new 40" Sceptre for $289 and it's been flawless.
According to tests and surveys - Mitsubishi has the worst record.
TVs sold under the RCA brand name has one of the best records for dollar-versus-life.
