    UE65HU8500T picture issue

    Hi. Please help. I bought this TV completely dead. The seller said it was working fine and suddenly died. I had no reasons not to believe him. Looked quite rich, nice and clean, house. Not somebody selling second hand TV and needed to make extra money. Complete TV with accessories. I have replaced main board and TV come back to life but with picture as per photo - left side correct, middle and right like burnt OLED. Also on right side is visible ghosting. Would you say it is a panel faulty or main board I had from eBay? Shall I try different main board and tcon or take it straight to dump? Shame as TV is in pristine condition.

                I am not sure what are you trying to say. Does the trouble is panel means the panel is faulty?

                      I believe this tv has side cof. As a last resort you can try removing cofs from the side that is affected.

                                  There is absolutely no configuration issue, who is telling you to buy boards or entering menu is totally out of the road, the image you posted show a correct image on the left but not correct on the right, this brings to only one answer, the tv hitted by an overvoltage or something gone wrong with the panel driving, depends on if the tcon is separated or not, now you have problems with the vgh/vgl signals so the row drivers can't turn on /off correctly the rows on the right, removing the vertical cof is an old technique, something better could be attempted, not by rookie user maybe.. you can also try the screen self test if you don't believe me, detach the MB, solder a wire between PSB 12v and tcon fuse input, insert current and.watch RGB test..

                                    Thank you. That is very informative. So as I understand I should disconnect ribbon cable between main board and tcon. Connect 12V to tcpon fuse and it will start self test?

                                          Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
                                          by Asraf Atb
                                          Hi everyone,

                                          Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

                                          Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

                                          I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

                                          Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
                                          by cheeky2
                                          I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
                                          Obviously the same LVDS connector for the screen connection...

                                          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...

                                          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)...

                                          Hi,

                                          I have confirmed that I have a mainboard problem.
                                          I have tracked no hardware issued on board so might be a software dump required.

                                          I have searched a bit but wasn't able to find anything for my screen:

                                          Here are some more details:
                                          Panel: cy-nn065hgev1h
                                          Main: BN94-14180M P08F

                                          Your help much appreciated!
