    Samsung Un50h5203f Backlight and sound no Picture

    This tv has a good backlight and sound. Has stand by light and will power on and off. My first thouhgt was a bad T-Con, but for the price of the t-con i could pay 30.00 and get all 3 boards. So i replaced all 3 boards new from shop jimmys. Still have the same problem. Is there anyone that can shine some light on how to fix it??

        So are you getting 12vdc at both ends of the SMD fuse with ref. to the chassis Gnd on the TCon when TV is turned on?

              Check BOTH sides of that fuse to see if you have 12 volt like Hamie and Budm asked.
              If you do,disconnect one ribbon from the t-con and try,then reconnect and disconnect the other one,see if you get halve a pic.

                        Good catch. You might want to put alot more tape over it before you screw it all back together, just to be safe.

                          exposed metal under the buffer board? You wouldn't have a picture of that would you?
