    Vizio E48-C2 - Wont turn on, light comes on and fades out when plugged in

    Have a Vizio E48-C2. Was told that she heard a loud pop, then her lights went out. An electrician came and reset the breaker but her TV didn't come back on. She brought it to me and I went to look at it, to my surprise, there is only one board in this TV.

    When the set is plugged in, the light comes on in the bottom corner and then fades out. I don't know where to check for voltages and can't find schematics for this. I have not broken down the set other than to pull the board out and check the diodes and caps. They all seem ok, but most of this board is microscopic. Any ideas where I should start looking on this?

    How about a picture of the whole back, could try with tv unplugged from power, unplug tcon cable from main/power board, plug tv back into power and see if backlights come on.

      Seems like if there was a loud pop there would be visible damage somewhere, doesn't have to be tho, take off the shield of the tcon and have a good look at it too.

        no T-con board in this. I got it working. The power switch was faulty. The little disc that was taped over the contacts came lose and fell off. Put some new tape on it and got it clicking. Was able to power on.

        Thanks

          Not sure if maybe the cable input is ok or not, not able to test it because my Dish doesn't have a standard coax, it uses three RCA plugs. She will pick it up in a little while.

            It has integrated T-CON into the LCD panel assembly.

                Right now they have those boards on ebay for 20 bucks, might be a good idea to have a spare.
