TV dead?

[69strat]

My TV is about 13 months old. It's worked great. Great clear picture.
I just turned it off a few hours ago and now it won't power on. ????
No warning signs or anything weird. It's just dead. I unplugged it,
waited and tried again. The other things in the power strip work.
This TV just decided to stop immediately.

It's barely a year old. My wife just wants to buy another new one.
But I'm hoping this is an easy, cheap fix. Any ideas on what I could
check?

Sorry it's a Phillip 27" (27pttp6442) flat panel 4:3 style which is
dated June '04.

The fuse?

No, it's certainly NOT the fuse, if the fuse is blown there is something
else wrong.

You could check for cracked solder joints in the power supply section,
also measure and see if you have standby voltage.

A fuse blowing is *usually* indicative of another fault. But it's by no
means impossible for a fuse itself to fail without there being anything else
wrong.

I've seen it happen, but it's exceedingly rare compared to the number of
people who assume it's "just the fuse" and replace it, often with a
bigger and bigger one until something else smokes.

Start by checking the power cord, then the fuse, then the supply, etc.
Eventually move onto more complicated things like the startup
circuitry, relay, degauss, etc. Finally, it should become clear
where the problem lies.

To be honest Filips is one of the worst sets . Take your wifes advice
this time but dont buy the same thing again

Seen a lot of these with fuse blown because of the DGS thermistor. It seems
that the inrush current at power on tends to weaken the thermistor, actually
causing a change it's cold temp resistance, which then promotes excessive
current during the Degauss Cycle. There is a mod for the tele if that is
the actual problem you are experiencing. Best to do some in-depth
troubleshooting to determine if that is actually the problem. Panasonic and
Sony sets also incur similar symptoms.
