Have TV Questions? Ask a TV Technician
Hello, We're not able to see the question that brought you here, so can you please reply back with what specific problems you're having?
Additionally, the pins are labeled on the power supply board where you want to check for "DC volts". Look at the silkscreen legend on the board itself next to the connectors- you'll see: 5.3V, 12 volt, and 24 volt respectively. You ground your black meter probe to the metal frame/ground of the TV, set the meter to DC volts, then use the Red probe to test those pins I mentioned above with the TV plugged in and turned on.
