Question about Samsung LTN1565 15 in. HD-Ready LCD Television
It's not a thermostat, it's most likely a bad electrolytic capacitor. What happens is a weld
inside the capacitor breaks and causes it to open circuit. When you heat it up, the
connection is made again until it cools and opens again.
In the LTN1765, the bad part was capacitor C21 near IC23 in the upper center of the board;
it's a 10 microfarad 16 volt surface mount electrolytic capacitor. I suspect the 1565 has
a similar board but the part ID may be different. Probably they had a bad run of these parts
since the failure seems to happen in all these TVs.
If you're experienced at electronic soldering it's not too tough to replace the part - use a
small iron. You could probably replace it with a radial electrolytic or tantalum with the
same rating - 10 microfarads and anything from 16-35 volts should be fine, if it fits. The part
costs less than $2.

There should be some kind of thermostat inside of the set that goes bad, but I could never find it and I was told you would have to replace the whole main board which now a days cost more than the whole tv itself.
