Philips TV blew Power Switch!

Hi All,

My Philips TV (68cm PowerVision - model no 29PT4673/75R) caused my GPO
circuit breaker to overload. Thought it may have been the degauss
thermistor (common problem so I've been told!), but noticed that the PCB
directly under the power switch is completely burnt away and the switch no
longer actuates.

Firstly, why would this happen? Seems odd to me that nothing else "looks"
damaged and the power switch is completely cactus (thermistor looks in
tact)!

Secondly, there is no markings on the switch for me to find a suitable
replacement. Would anyone have a databook or something they could look up
and let me know what the switch is?

Appreciate any assistance,

Jason.

** High resistance ( BURNT ) switch contacts generate heat which
CARBONISES the brown turd PCB material.

Voila - eventual massive short out.

That's good I suppose - at least there would be nothing sinister happening
beyond the switch causing it to burn out?

Powerline surge? Old, faulty switch? Could be many things. No idea on
the part. try the usual sources.
