    SONY KDL46V5500 LCD half shorted!

    Hello everybody,

    While waiting for the parts for my other TV i took another one and after troubleshooting i found out that my power supply from T-CON board was defective. Had the 12V input but no output to LCD. Fuse was OK and so where all the caps.

    I order a new T-CON board and after installing no picture again, so i disconnected the right ribbon from T-CON to LCD and the screen turned on only whit half a picture of course, and the other half completely white.
    Measured on the V-ON on T-CON and had the correct voltage.

    If i connect the other half (left ribbon) or just this one i get no picture, only sound, and my T-CON voltage (V-ON) goes to 0V.

    Is my left side from LCD shorted?
    Is this possible to fix?

    I think it could be a problem on the small board where the T-CON connects to, There are some components on it but it is made of a sort of plastic like a ribbon.

    Thanks!

      Check those MLCC caps on the driver board, the board/s between the tcon and the panel for low ohms, expect over 100 ohms on those when testing with meter set to 200 ohms. Check with power cord UNPLUGGED, meaning no power going to tv.

          Nothing wrong with the caps. All over 200 ohm... What could it be?

              potentially the set might have tabs on each side of the panel .... note they can only be checked / viewed from the front (ie. need to remove the bezel / front plastic frame). A common problem for some sony's of this "design" is connections / panel integrity at the corner. I assume this panel has edge boards at the top of the panel base on my sony experience of another model. IF so, then the problem is in the top corner.

                  Sony KD-55AG9 TCON?
                  by bbrain
                  Hi,

                  I have this problem with my Sony 55' AG9.
                  It flashes 4x.
                  I have found the service manual, and seems it is the TCON.

                  Before I buy a TCON can someone check the vid?



                  Thanks in advance!...

                  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...

                  Sony KD-65x8500b - bad Tcon or panel?
                  by rimwall
                  Hi, hoping for some views on this one which I've not come across before. The TV generates an image that has 12 noticeable bands across it. The image is still there and accurate, but the colour (or perhaps the brightness) changes gradually across each band which creates a noticeable 'step change' at the edge of each band. Given it's a 4K TV with 2160 rows of pixels, I'm guessing the 12 bands correspond to 12 gate drivers of 180 rows each. If this guess is right, then perhaps:
                  a) all the gate drivers are malfunctioning the same way (which seems unlikely), or
                  b) the Tcon board is malfunctioning,...

                  Sony KD49X8000H - Sound, backlight, no picture

                  Hello all!

                  This post will mostly just act as documentation for my undertaken troubleshooting steps for this TV. Advice will also be appreciated for things to try next

                  Picked up the TV in thread title from a retail returns auction, symptoms were as described. I started my troubleshooting attempts by shorting the 19V PSU rail to the 3v rail with my multimeter... Doh. Big spark, dead PSU, TV not turning on anymore. Picked up a new mainboard and PSU locally from someone here in Sydney, wasn't sure if my butterfingers had killed both and was a big drive to pick them...
