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.

Measure all the voltages coming off the power supply board first. Then move to the board that controls the picture. This board has one or two wide flat flexible cables running form it to the bottom of the screen.

Do you have to have a HD cable to hook up a PS3?


There are two ways you can connect your PS3 to your VIzio. First, you can do it with HDMI cable. Here the HDMI output from PS3 goes to HDMI input of the TV. Second, you can do it with the AV multi out cable.Here the multi output from the PS goes to AV input of the TV. After doing this please select the source accordingly. Good luck.
