Hi I got Sony 46hx853, no power or standby light , service manual says to check standby voltage on pin no 10 I think on main board, and if voltage is there, then replace main board , standby voltage is present , I have another main board from different tv, but the main board is near enough identical except the audio connectors , I plugged it in and I get standby by light on tv, so the service manual seems correct, but I don't want to replace the main board as it's expensive, the near enough identical main board I got has a damaged connector and all the ic chips etc are identical, so I can use that board to salvage the parts from, the problem I have is no schematic so I'm kind of confused what to check j next , as there's no obvious problems on the main board, like no burnt components , checked some smd caps but no short circuit on them, nothing getting hot, so just need some help and advice, I can solder smd parts and got all the equipment, just need to figure out the problem,
Hope someone can help ?
