    Report back soon
    it is wrong... its always between 20-23V no standard for 24V. as its for OLED driver... currents will depending on adjustment.

        maybe less or more depend on yours luck..
        you have OLED Cells shorted on the Module... if the short went out... the screen will light complete pattern... its look that the you have blue cells line had short , as you don't get blue.... only 2 lines white... mean at the white lines the blue worked but they are shorted with red and green.. do displaying white... RGB

          but be careful.... the module could get fire on the shorted area.. so be ready

              PSU on OLED Tvs used only ONE for all TV size... V to T-CON ( main boards are all the same.
              but the V to OLED driver which go to T-CON will be different depending on TV size and how much OLED cells build in module ans how much currents they need

                  Fire also should be something say before hand lol I was not ready. But no fire. And okay on voltages

                  The white lines in the middle? Yea they show up and leave randomly. It just cycles the picture shown. Red white green blue back and fourth with small white line randomly in middle of full screen

                    well from my experiences its Module... but the way the line it show from left to write... its T-CON responsible on it... if the lines from top to downside then 100% module... take the risk and replace t-con if its cheap LOL

                      Okay, all the lines are left to right. Although that color line is up and down, all the lighting up is all doing left and right lines. No lines are up and down.

                      Will do, tcon ain't that expensive thank you

                        by the way... inspect all 4 ribbon cable under loop from both sides... who knows could some play with them before and damaged them,,, just in case

                        Note important.. after inspecting you should put them back at same order before... to avoid later line light in image

                          I did look at those as well. I even cleaned them off, appreciate that. Owner did say he didn't do anything at all, looks like had never been opened before. TCON like $45 so gonna go with that option. Thx for all info diah, davi, Sony. This one will go on the wall if it's fixable

                            1) In your pictures it lacks the one that shows the table of pins for the psb to tcon cable,
                            in your list it lack also..
                            2) in the linked thread the other model appears almost the same and he has 24v not 21v

                              he got V on pin labeled 24V. doesn't mean its 24V LOL... 21-23 V all will be called found V on 24 PIN... at the end mean PSU 100% fine same in this threat..

                              so do you think he measured 24.0V LOL

                              if you want to know exact V. the PSU should be stand alone with out any load.. just it alone on table

                                    its fine.

                                    you can let the tv in original all cable plugged in... lvds etc ribbon... only the socket evdd disconnect it from power boards side then turn on... tv should start and you have the audio optic port lit red and remain on.

                                      if you look on the LVDS down one ( which you disconecct it before and TV remain ON.with black screen ) there are test points ( EVDD_RESET ) this points go high to round 3.3V at time the Tv shutting down because of the SOS signal.

                                      if this points jumper to chassis to remain always low the TV will remain on and you could see the screen on... but in which condition this is the questions..

                                      so if the the points go high.. mean EVDD at the module had short cells too

                                        The only way TV turns on as normal is if I disconnect the bottom lvds from main to tcon. Any other combinations of cable disconnect does not allow TV on and throws error code. Gonna report back once I get tcoj on Tuesday and then test voltages. Thx

                                        Edit I reread your message and you realize that cable disc keeps on lol. But yes I'm gonna wait since it's on the way anyway. Let's pray to the panel gods that it's the TCON

                                          TV is done. New tcon same results. Panel short. Thanks for trying. I have bad luck with expensive tvs
