I have a Vizeio e470va that has backlight but no picture.
When I turn it on, I get nothing on the screen but the bezel light “VIZIO” will light up bright for the duration of the TV being on.
About a second after the bezel lights up, the backlight will come on for about 3 seconds. During this time, the blue LED on the inverter board will come on but then will fade out after approx. 3 seconds.
As soon and the blue light fades out, the backlight turns off for about a half a second and then then back on.
a. The bezel light is on the entire time
b. The blue LED comes back on and fades out after the 3 seconds
At this point it's done doing anything and will sit like this (Bezel light on, back light on, LED not lighted on inverter).
I have checked the voltages on the power board and at the inverter to ensure power is flowing. All seem ok. I also checked voltages coming from the main board to the T-CON. All seem ok except I couldn't get a reading on the fuse on the T-CON (see photo)
When I check it, it reads no voltage but has continuity when powered off. I was able get a measurement on one of the small caps under the cage of the T-CON close to the fuse and it read 1.8v.
The TV i have and the problem are identical to the one here https://www.badcaps.net/forum/showthread.php?t=38729 except he got a reading on the fuse on the T-CON and I didn't. My journey stopped there. Any ideas?
