Hello, My parents Samsung UN46D6000 stopped working: No power or standby light. I’ve removed the back cover and confirmed the fuses still have continuity and the input to the board is reading 120 VAC. Where on the board can I test the voltage to the mainboard, and what should it read?

youll want to look at the powersupply connector leading to the main board. there should be a legend printed on the board and you can take your readings to see if they match up. let us know if you have questions.
