Vizio 60" Smart TV Repair

[adept]

Hi,

I took apart my TV because the screen went dark. The backlight still comes on but there is no picture.

This is a 2013 model, not the recalled 2012 unit

I checked the voltages. They're normal when the TV is off but when it turns on, both dip to a couple of millivolts.

The capacitors have no visible sign of damage (i.e. pin holes in the top or bulged tops)

The capacitance measured on the input and output of the regulators both exceeds the abilities of my meter.

What should I do? Do I give up?

What model number is it??

It's a E601i-a3e. I tested the T-Con board according to an online testing tutorial. The MOSFET driver for the panel has a short from drain to source, is not acting like a diode, and I'm getting 0V on all the pins on this MOSFET. This could mean the panel is bad, but I didn't have problems with the panel before. Anyways, looks like a $70 gamble to get the T-Con board and I don't know if it will be worth it. What do you guys think?

Maybe this helps

Replace the MOSFET and see if it works. Or just unsolder it, and see if the short is gone.
