      First of all that's a plasma not am lcd so there is no tcon board in that set. Its a plasma made by lg. You need to be looking at t esting the ysus and zsus boards. More specifically the ipm modules under the big heat syncs to start.
      Did I leave the soldering iron on?

              Well firstyou need to see if your voltages are up or not in the power supply. Does the tv stay on now? You need a voltmeter and set it to dc. Black lead or ground or chassis of tv. Red lead test vs and va

                  also can check the buffer boards by removing the upper or lower one at a time.

                          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...

                          Sony KD-75XF9005 grey Picture but Sound. TCON or panel?
                          by iglitare
                          Hi,

                          i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
                          Backlight seems to work, Sound (Setup menu after reset) works.
                          If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
                          Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
                          With my small knowledge i would think at least the cables are good.

                          Can this happen because of a bad tcon board?
                          Or is it always a bad/shorted...

                          Samsung LCD TV no picture backlight on no 12v at tcon
                          by shelby5041
                          hi
                          i have a samsung lcd tv

                          it powers on with sound and backlight but no picture

                          all voltages from PS are good 12v 3.3v and 5v

                          whats odd is that at the tcon i tested voltage across the fuse on the tcon and i get 0v

                          i figured main board issue..so i ordered a used main board....when i put replacement main board in i still have same issue

                          no 12v at the tcon fuse

                          i disconnect the panel ribbon cables to rule out any panel issues and i still have no 12v at the tcon fuse

                          the odds of having 2...

                          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...

                          T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)

                          Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

                          The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

                          Original T-con:
                          Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

                          First replacement T-con:

                          I thought it might be t-con and ordered new t-con from china(supposedly tested)...
