Re: Vizio E421VA - Blank Screen w/ Two Thin Vert Lines

According to the seller I bought the main board from, there are two boards for this model and they are not interchangeable. I matched my board with what they had pictured in the listing yet what I got appears to be the other board. I didn't notice the difference until I posted here and looked closer for information gathering purposes. I wanted to be prepared for any questions I might get asked.

Re: Vizio E421VA - Blank Screen w/ Two Thin Vert Lines

After closer observation it appears I have purchased the wrong main board. I'll post the results once I obtain the correct board. Thanks for the feedback.

I bought a Vizio E421VA LCD TV in hopes of repairing it, having fixed several LCD and Plasma TVs in the past . I have replaced the main board and the PC board. I have verified that that the power supply is producing 5V, 12V, and 24V. The TV powers on. The Vizio badge on the bottom of the bezel lights up. I get the VIZIO splash screen for a few seconds. The screen then goes blank with the backlight on. I then get two thin vertical lines towards the outer portion of the screen. These lines vary in color, sometimes orange, sometimes purple, and sometimes green. The menu does not appear on the screen...
