I Have a ViZIO smart TV Model # E420i-Ao Ser# LAQKNRBP0500931 has sound but no picture No light show up in the back and can see any thing on the screen with flash kite when you push channel or menu


It is a common problem for Vizio TV uses a LG 42" & 47" display panel.
The problem is defective back light LED strips, you have to open the entire panel & find the defective strips (it marked as L1, L2 (left), R1, R2 (Right)), the part number usually marked as 6916L-XXXXX.
Both Vizio & LG will not sell the strips, you have to find them on EBay for new or used one.

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.

Black screen, audio, no backlight. What's wrong?


This is most likely a failure of the actual LED strips themselves. They do attach to a board at the edge, it could be the board but you have to order the board and strips as one unit.
