My Samsung UN58H5202 just one day did not turn on anymore. No red standby light. Nothing.
So I googled and found some troubleshooting ideas and they said to check the power supply board. I Checked the pins for Standby Voltage and other pins next to it where the main board plugs into. All were reading 2.5V (except gnd which was as expected 0). I went to buy a replacement board and the parts store said the new power supply board may only work for a few days because faulty LED backlight strips on my unit may cause the power board to burn out again and that this is a common problem with this TV. Anyone ever heard of backlight strips doing this to a power board? TIA!!
