              I watch the video, but not sure which ribbon contact to tape off. As for the t-con board I still have the old one.

                  is the 4th pin, on each cable


                  right side, 4th pin right to left, on both conectors

                  Left side 4th pin left to righ on both conectors , but you will need to test wich side to block testing one at the time

                          So if I understand correctly each ribbon has its own clock signal?

                            yes , each side each conector, always in the 4th pin

                                    Hello everyone,

                                    I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

                                    Hi guys

                                    I just started fixing 4k TV few months ago. so I am still learning a lot
                                    I got this tv from friend complaint is ghosting or horizontal lines on image.

                                    never saw the original symptom but I took the tv back home. the funny part is that after bringing to home, the tv worked fine no issue for 3 weeks.
                                    then it started to show the ghosting white image.
                                    I started using the tape method, but this tv does not have a T con board and it has only 1 ribbon cable from main board to the tv panel.
                                    it has 3 thin small boards at the bottom of the...

                                    Samsung UN50TU8000FXZC shows thin horizontal green line when warm
                                    by cubytus
                                    Hi to all,

                                    I was given this TV, an entry-level 4K 50" set. Some have criticized its lack of contrast and relatively poor colour rendering, but for my needs, it's very decent.

                                    I reset everything to factory settings, but this line keeps on fading in and out when watching a streaming channel from the Tizen firmware. Interestingly, it only happens when TV is warm, after about 1h45 of it being turned on.

                                    Watching a movie from an external source doesn't trigger the line as easily (needs 2 hours), and from a normal viewing distance, is hardly noticeable. It...

                                    Sony KD-55X9000F TCON Issue
                                    by thelankanguy
                                    The TV shows a black screen with no image.
                                    TCON ribbon connectors were disconnected individually for image and there was no half image even.
                                    Later both ribbons were disconnected and TCON voltages were tested.
                                    12V, 3.3V, 1.8V were seen present but VONE signal reads 0V.
                                    There is also a short to ground in this circled inductor.
                                    Is this a TCON issue or something else ?...

                                    Sony KD-55AG9 TCON?

                                    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!...
