So I finally got my TV back from repair. After the initial mainboard replacement, the backlight would not turn on. The repair tech left me mid way through the software install and then had to come back out. He said that it must be software related, but, I waited a full day for the software to "finish" installing. If I shined a flashlight up to the screen with the turned off backlight, I could see the Welcome sign.
So they sent another mainboard replacement. The second mainboard replacement had the same issue - where the backlight would not turn on, but the software had finished installing. They tried also using
update_loader.pkg
instead of the original firmware download name. Each time, they had me installing the 6.7140 firmware update, when this occurred. The technician finally took the TV on the second repair. They returned it today and told me that Sony sent them a different software version to install which was able to get the backlight to turn on after replacing the mainboard.
When checking out the software and about me page, I noticed the following:
- Device Name is stated as XBR-65X900F, indicating that this was recognized as a 65" tv, even though I have a 55" (XBR-55X900F). Will this be a potential problem or a concern in the future when it comes to firmware updates (I understand it is just a name, but I would have expected it to be picked up correctly as XBR-55X900F)?
- The Kernel Version is: 4.9.125 #1 Mon Oct 12 21:22:22 JST 2020, is this accurate for a 55X900F?
- Build Version: BRAVIA_ATV3_4K_UC-user 9 PTT1.190515.001.S38 671401 release-keys, is this also accurate for a 55X900F?
- The Serial Number is not getting recognized by the Android Firmware, is this expected? Shouldn't the firmware be burned in/entered after flashing the board?
Really appreciate the suggestions from everyone here so far, going to hold off on any updates and just connect other devices to it for now until more stable firmwares are released. I do hope everyone gets their issues resolved, this updated firmware obviously has some flaws.
