2 yr old Vizio e470i-A0 lost picture and sound a couple of months ago. Checked capacitors on the power board and main board, looked ok. Replaced power supply, no change. Replaced main board, restored sound and got images in screen but screen remained black. Replaced LED strips, picture restored. TV functioned normally for about a week, but now the screen is black again. WTF?
