I have a VIZIO E321VL that would not do anything. I replaced the Power supply board and now the VIZIO logo lights up amber and changes to white when power button is pushed. I got nothing else. I replaced the main board and still get no sound, no picture and no back light. Both boards were new from Shop Jimmy so I am confident the boards are not the problem. I now have $150 into this TV and it still does not work. BTW I do not have the remote for it. Anyone have any suggestions what to do next?
