Older Sonys are really very reliable and lasts for a very very long time. I don't know about the current Sony CRT TVs.
Next for me would be Samsung, especially their Slimfit TV.
Worst for me is JVC. We had 2 JVC TVs that conked out in less than 8yrs. And JVC's service really really sucks big time. I had to email JVC's Singapore headquarters just to have the local service center inform me of the status of my JVC VHS player being repaired under warranty. And we had 3 VHS players by JVC that broke within a few months between each players, all were less than 4-5yrs only.
