Hello I have a vizio v037l fhdtv20a that has no picture or sound. The vizio light changes from amber to white when I power it on but thats it. I have 1.5 vdc to the a and b pins going to the main board and inverter. I have 5vdc on the pins to main board but no 12vdc or 24vdc. I have nothing at the pson. I jumped the 5vdc to the pson and then I had all my power. I dont know where to go from here.

Check all your voltage regulators on the main board. Vizios have problems with them failing. My sig file below has details.--- begin sig file ---

F3 is OL? That sounds like a problem. Can you check the DC volts on each end, relative to case.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
