Hi Guys,
I need your help with my TV. So far I replaced Caps on both boards(even when tested good - used atlas ESR), Checked PSU transformers with blue ring tester, Check all diodes, resistors and mosfets with Atlas DCA pro, But I cannot find anything wrong with this PSU. When I plug the power and turn the TV on it will stay on for about 1 min then it will shut itself off and then after about 30 seconds it will turn on and then shut off again. Checked regulators on main board also fine. I think it's the PSU since I am getting a buzzing sound where the inverter is.....Any ideas and help will be very much appreciated. This is my 1st post so please correct me if I did something wrong.
