    Vizio 47"

    Hey all I am wondering if I should buy this or not and what the diagnosis is for this thing they didnt give much info on it other than they wanted 50 bucks for it. Heres the pic. Its an LCD but no model number was given. They did say that it was sporadic for whatever thats worth

    That could be the t-con board dont buy it unless you can get the model number, youll need the model number to find what available boards you can buy, it also could be a dirty connection to the t-con or main board (not sure what is in the vizio but im guessing its cheap) my guess is t-con issues

      Looks like bad inverter.
      Doesn't look like tcon issue.
      To confirm inverter diagnosis you can check if dark side has any faint glow. If the glow drops off on that side it's probably an inverter fault.

        Agreed 100%. I just fixed one of these less than a month ago. It looks like a VW47L from the front if I had to guess. The 680uf 35V capacitors on the inverter boards fail. The one I had I was able to just change 2 caps on each inverter board and it was good as new.

          I agree with Tom and Aaron.

              TCON and self diagnosis!
              by angelos
              Hi Guys.
              I have experienced something rather unique and need to find out by the forum what to make of it.
              I got in this set, a JVC or Telefunken LED TV whose complaint is that sometimes the set comes up blank with the back lights running. So I switched on and yes there was a blank screen and back lights were running. I checked the fuse on the TCON and sometime later I lifted the set off the table to check the image (the TV has no feet to let it stand upright) and noticed the set was cycling red, green blue, test pattern, blank then all over again doing this. Suddenly the no signal...

              Vizio E55-E1 bad backlights or bad inverter?
              by x_orange90_x
              I just got this tv today and it appeared to have no backlight on. After taking off the rear cover and checking again in the dark I can see that MAYBE one quadrant is lit.. But still it's quite dim. I was going to check the LEDs with my tester, and I found LED 1 and LED 2 + pins on the wire from the inverter, but I couldn't identify a ground. Nonetheless I tried using a mounting screw on the inverter board and also the chassis as ground but regardless my tester reads 300 which is what it reads when there is no voltage draw.

              I don't know how exactly to test the inverter itself. Is it...

              VIZIO E70-E3 Half picture with half TCON
              by Fly_Among_Stars
              Hi,
              I have a VIZIO E70-E3.
              Symptoms: Black screen, no picture, but LED backlights are working.
              I probed the power board and voltages are as listed on the board.
              Main board appears fine, too.
              I believe the problem is either a bad T-CON board, or connection to LCD, or bad LCD.
              There are two separate ribbon cables feeding the LCD.
              If both are connected, the screen is black.

              If only the ribbon cable that feeds the right side of the screen (when viewed from the front) is disconnected, the left side of the screen shows picture and...

              TCL 50S535 bad tcon or panel issue?
              by x_orange90_x
              Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
              by Tynan Dill
              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

              Upon bringing it home and plugging it up, it showed a standby light.

              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

              The screen seems to blackout and stay black, but with a flashlight I can see the display.

              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

              Assuming...
