SOURCE: I have a Vizio 70" led model E701i-A3E it started getting white spots then it just went black has sound but no picture. What parts do I need to buy to replace to fix this do I buy all three boards

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

SOURCE: my 70 vizio E701i-A3E lost picture graually over 30 seconds while audio remained unchanged.

Did the picture fade away or worked one second and the next it was black?
