My previous 29" 4:3 JVC TV had a power device fail after 3 or 4 years.
No heatsink compound!!!
When the bloke arrived with a pack of replacement components to fit, I asked
if he was going to use heatsink compound? I had some to use otherwise!
Too messy to bother with at the factory? (or the sets would be far too
reliable if they did use it? :-)

Got a rear-projection Tosh 42PW23P about two years ago. No problems so far.
