    Sorry to be a pain again, but is checking all fuses on the control board the last thing before getting another board?
    Cheers

      Not much else you can do with minimum service info of the main board.

          I have bitten the bullet and bought a used main board Is there something I should do to protect it whilst replacing it. IE disconnect anything(other than have it off and disconnected from the wall) before doing so.

          Thanks

            Success, 2nd hand main board has now brought new life to the Sony.

            Fitted it this afternoon, inserted the USB stick with the latest software/firmware ready to go.

            White light at bottom came on white, flashed for a while, it turned to green, and then sat there with the white light flashing. From memory I had seen this pattern when it has done an ota update, so I left it alone. About 10-15mins later the scrolling android startup screen splashed up, and from there all normal things were available.

            I ejected the USB and tried turning the tv on/off a few times and all is good.

            I'll refit the back cover panel over the next few days, and all should be good

            Many thanks to all those people here whom have assisted me, and without all your support, my outcome would never have been achieved.

            Thanks everyone...

              Thanks for feedback.
              I stop Automatic OTA updating, regular updating, I will wait a few months then look on line to see if many people has issue with new update or not. I had a few TV's in the Video lab that had lots of issues that were not there before updating.
              If the TV works fine and fit what I need then I do not update them.

                Thank you...I just did the software update as the tutorial said this must be done each time a main board is changed. I do take your point in regards to waiting for others to use any updates, so that problems are not yours straight away

                    Good news another save. +10 on Budm's advice about stopping auto updates.

                      Bad Panel in Sony Bravia X850G
                      by guidodroid
                      Hello all,
                      I'm trying to understand what is the issue with my 26 months old Sony Bravia KD-65XG8505 (XBR65X850G).
                      It is just few months out of warranty, so Sony doesn't want to do anything, and the local replacement shop also tells me that it's not worth repairing (alhtough this model costed almost 1000 euros just 2 years ago...).

                      Few nights ago the TV started showing some horizontal lines and distorted colors/geometries in the bottom part of the screen (see attached photos).
                      The issue is not as bad as others that I've seen around, but is indeed noticeable...

                      Sony Bravia 75X850C panel
                      by m4a2t0t
                      After changing out the backlights I have a single green vertical line on the left side of the screen. Is there any way to fix it? I tried putting pressure on all the tabs and on the top of the panel but neither helped.
                      Does Sony epoxy all their panels or just the expensive ones?

                      Sony KD-70X690E Bravia; Bad TCON? Bad panel?
                      by swrb898
                      What's wrong with my TV: the TCON, the panel, or something else? I'm stuck.

                      Problem:

                      Last week, my Sony KD-70X690E 70" stopped displaying a picture. The TV powers on, and the back lights power on. However, the TV doesn't seem to boot up. I say this because the SONY splash-screen logo does not display, nor does any picture display, nor can I invoke a menu by pressing "Menu" on the remote. Other than back-light bleed, the screen is black.

                      My troubleshooting got me this far:

                      With the left-hand TCON to bottom-board ribbon cable...

                      Sony Bravia KDL-40V2500 that will not power on
                      by PopsCaps
                      I have a Sony Bravia KDL-40V2500 that will not power on. The indicator flashes red 3 times.
                      I do not hear any sound and I cannot see any backlight.
                      I have tried disconnecting every cable on each board one at a time to see if anything changes.
                      The only change is when I disconnect AC-DET cable on the Power Supply board or on the other end if I unplug the CN7009 connection on the B-Board and try to power on the TV the indicator will stay on solid green until I power off.
                      My friend ordered another used power supply board but it is also doing the red indicator flash 3 times...

                      Sony Panel Swap Experiment 65x900h with the panel from a 65x930d
                      by r3vsEngIT
                      65x900h with the panel from a 65x930d.

                      900H: model yr 2020, Samsung panel
                      930D: model yr 2016, Innolux panel

                      spec wise the panels are the same. the drivers and tcons are obviously different but what made me want to give this a try is that the wiring diagrams for the data signals going into the tcon for each tv were nearly identical. there are only a couple pins that i am unsure about and that is what brings me here.

                      the 930d has the DPS board where the 900h has none, however, if you follow the pins to the BM1 it would appear that the signals...
