Troubleshooting a Sony Bravia XR TV startup loop with manual machine

Have you tried disconnecting all HDMI cables and the Ethernet cord to see if an external device is causing a CEC conflict during the boot process? I spent hours dealing with a similar "black screen of death" on my old display, and I discovered that sometimes a simple firmware re-flash from a thumb drive can bypass the error if the OS has just become corrupted. I managed to find the full technician's breakdown on Manual Machine https://manualmachine.com and it was a total lifesaver because it listed every single blink code and the corresponding part that usually needs replacing. You should locate your specific Bravia model on their site and look for the "Service Manual" rather than just the "User Guide". If you can get it to stay on for even a minute, you might be able to run the self-diagnosis tool from the hidden service menu.

I wondered if someone has access to the internal service manual that technicians use, as I decided I want to try a firmware update via USB before I give up and buy a new TV. I attempted to hold the power and volume buttons while plugging it in, but nothing changed, and I'm hoping to find a step-by-step guide that explains the blink codes in detail.

Hi guys! I realized this morning that my home cinema setup is basically useless because my Sony Bravia XR television has entered a dreaded "boot loop" where the logo flashes and then the screen goes black again. Has anyone found a reliable way to perform a factory reset using the physical buttons on the back of the set, since I can't even get the software menu to appear on the screen?
