Freak, any chance you'd change this video to being a non-private video? I'm working on a set and would like to watch it. I've tried everything and still have a blank screen with backlights. all components test fine but I see that someone in earlier posts was talking about a "red cap" and seeing 15.3V there. I don't see that but the transistors, other caps, and other spots have the correct voltage. You never really mentioned this "red cap" (mines orange like your photos show). Any idea of what could cause 0v on this orange capacitor?... -
Hello,
Sorry for taking so long to reply. This project took the backseat as we had our first kiddo this year. My wife is now wanting the repair room thrown in the trash so I'm trying to get everything fixed up and learn again. When plugging the TV in, it seems like the backlight now is working great but still no picture. I must of been a dummy and just hit the power button lol.
I assume standby is just plugging it in (backlights still come on) and that turned on is when you hit the power button (Backlights shut off).
At the PS connector that goes to the main board...Leave a comment:

Sorry it took so long to reply.
yes f101 has voltage on both sides of the fuse, indicating that its good (when jumpered on power supply board as mentioned previously).
any other ideas?Leave a comment:

Where is this tcon fuse?
I did notice that when its jumpered I no longer have voltage across the silver roung cap (on the right side of the Tcon photo). I had voltage there when I did have backlights.Leave a comment:

Vizio E701i-A3 backlight only and now no backlight
Hello all,
I’ve tried to repair TVs in the past with some luck. Toms repair manuals got taken down and now thats a bit harder.
I picked this TV up hoping for a quick fix. When the TV would power on, only the backlights would come on. The owner told me they heard loud screeching before it shut off. This alone makes me want to think the main board has an issue.
As I researched, I found the TCON/driver boards were an issue on this unit. I went in troubleshooting the TCON but found good voltages on the TCON. I followed shop jimmys guide to test the transistors and they seem okay....
