    XR-77A80K Dead set, red light blinks 8 times. Cannot find error code list.

    I have a XR-77A80K here. When plug in & press power, white lindicator light flashes on & off. about 30 seconds later, indicator light flashes 8x red. Checked Sony, Power reset = unplug & plug in. Factory reset involves turning it on, then pressing remote buttons when a picture shows. Well, neither of these "resets" are for a dead set like this. Anyone know what 8 blinks indicates, from the schematic? Thanks!

      Thank you! Do these mainboards brick the tv and require a software update?
