This TV died abruptly, and completely without warning, while it was turned on. It appears completely dead, other than than that the degaussing still works.
There was some burning smell evident immediately after it failed, but nothing has obviously suffered heat trauma.
Presumably there's a problem with the power supply, which looks like a switch-mode. One thing I've noticed is that when power is connected, it emits a clicking noise - about three times a second. When the power is disconnected, the clicking doesn't stop immediately but continues for several seconds, slowing down.
The clicking noise isn't coming from the speakers. I assume it's coming from a transformer or choke.
Ring any bells?
