TV Startup Music with no Picture after Main Board Replacement
I was advised by an electronics technician that the main board in my Sony XBR65X850F was bad. I ordered the replacement online and completed the swap myself. Now, when I plug the TV in to power, I hear the relay click and see repeatedly alternating flashing green and amber LED light and the startup music the TV plays when entering setup is audible but no image or backlight of the screen is occuring.
I tried several things last night: 1 - power off and on 3x; 2 - plug in USB flash drive with correct driver from Sony website thinking it might need pairing; 3 - changing the file-name of the driver to “update_loader.pkg”
Is it possible that I have a T-Con failure? Anything else this could be? I have double and triple checked all of the connection at the main and power boards.
Thanks in advance!
