Title: Replacement part
Post by: dcbrown73 on April 14, 2021, 05:54:55 pm
Hi all,

A have a friend who has a Samsung Plasma TV.  The power supply is not functioning and it appears there is a thermistor that is burned on it.  The PCB marks it as a NT801S.   The only places I can find these are mainly in the UK. 

Is there an alternative part / part number in the US that anyone would know of?

Looks like a 10 ohm 6A max continuous current NTC thermistor:
