                                  If someone else is having this same problem disconnect the IR sensor from main video board and your TV should work. Hope this helps someone out.

                                      Sony XBR-75X950G seems dead with a black screen but backlight and sound is working and no blinking red lights
                                      by Audeze
                                      I have a 2019 75" x950g, and while playing a movie, the screen suddenly went dark in a weird way, where it faded towards one corner into being fully black. Now the TV turns on, and the backlight comes on, but there is nothing displayed except black. Sound still comes through the TV speakers, and i have tried doing a hard reset using the volume - and power buttons while plugging the display back in, but it did not fix it. I can confirm that pressing buttons on my remote is still doing "something" because I'm hearing sound still, even though the screen is black.

                                      B) On a hunch of a locked up Google OS, plugged in a USB memory stick with latest FW and plugged it in. It booted into the update screen, completed the update and restarted to Home screen.
                                      C) Was able to perform a Reset from Settings menu and completed out of box configuration.

                                      SONY KDL-46R473A ALMOST DEAD NO STB
                                      by bohaboha
                                      Hello to everyone in this wonderful forum.
                                      I have this SONY LCD TV KDL_46R473a
                                      PSU GL5 APS350 :1-888-122- 12
                                      MAINBOARD FY13_EU IP-012C101-4010
                                      black screen ,no STB no life almost death.
                                      on PS all the required volts are present 394V on the main cap and those on cold side 12.41V,3.45 and 3.45 are on
                                      Also 3,5,and 12v are on.
                                      nothing happens if i disconnect the PSU from the mainboard as on Samsung because here i think the mainboard gives the signal to the ps.
                                      don't know what to do next all suggestions and advice are very welcome​...

                                      I tried reset by unpluging an holding vol.- button.

                                      Sony 55W905 dead
                                      by Talyn
                                      Hi,
                                      My Sony W905 started to turn itself off an on every few minutes and blinking 8 times red in standby. A few minutes later the tv was completely dead.
                                      I can only hear the click of the PSU when attaching/detaching the power cable. No standby LED.

                                      Any advice? Thanks!
