Recently started having trouble with our Westinghouse 47F430S TV where the TV either would immediately power off or refuse to power on. Seems this is due to a faulty capacitor. On some models this is TC51, however it was TC31 on mine. This is a 470uF 16v capacitor.
When I tore my TV apart I found my capacitor was surface mount, versus the through-hole I saw discussed elsewhere.
First I used my soldering iron to remove the old surface mount. It was somewhat difficult to heat it up, due to the large PCB.Then I bent the legs of an appropriate through-hole capacitor and installed it in it’s place.
The TV powered on and I am running a burn in test to make sure it runs for several hours…
