My Experience: I bought this TV from Costco as a used display model (no warranty, no problem) about 14 years ago.
For 14 years, the HDMI ports have made it my default PC monitor, the component in ports have carried it through the console eras, and it just doesn't quit.
Problems: After 12 years of heavy use, the display takes about 15 minutes to warm up, leaving a washed out area near the top of the screen. It goes away, but it is still annoying.
