Hello,
I recently received a 40" Samsung tv model HG40NA593LFXZA that I attempted to turn on before bed and the red standby LED only blinked momentarily before staying off. I opened it up and don't have a lot of info for you guys right now other than I was getting 12.9vdc at several points on the power supply board pins that were on top of the connector going to the main board. I know there's 13 pins, but I only had time to check the top ones. I was getting over 5vdc at the last 1 or 2. When the ribbon between the power supply and main board is removed the backlight comes on. I'm assuming this is a main board issue. Any advice to the contrary would be greatly appreciated. I will have some photos and more precise test point values when I get home from the dungeon.
Thanks in advance!
