I am getting frustrated with this tv. When I turn on the tv, it eventually starts clicking and I can test all the voltage output after the click, then the voltage goes to 0v. I can't take any voltages without it jumping around. I tested the ESR on all the electrolytic caps and they were good. When testing the voltages on the LDO in the 5v stby circuit, the input jumps around between 5-5.2V. Since I can't get a steady 5v stby I can't even shunt the RL_On to 5stby so I can test the voltage outputs without them jumping all over the place. Can I use an external 5V source to get the 5V on the standby, any suggestions?
