Troubleshooting a Sony Bravia XR TV startup loop with manual machine » S4 Network
#1

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.
