Sony TV OLED Bravia XR-77A80CJ blinking red 4 times…no picture.
Last night my Sony OLED TV (model XR-77A80CJ) decided it was going to stop working and showing a red light blinking 4 times.
I’m looking for the service manual for this and can only find the user manual, so if someone can help me out with a link to the service manual that would help a lot.
I’ve seen some say it’s the T-con board, others say it’s the main board etc. Does anyone have any insights on how to fix this? Perhaps which board I should either replace or what even to look for?
Thanks in advance!
Ps. I tried hard resetting it but I cannot seem to find a physical volume down button on it :/
Is this a good question?

@davidelston does it have a chassis number on the label?
