Any updates on this?

I have same issue, no screen/no backlight, laptop tries to turn on, CAPS solid on, power led blinking orange, around 15sec, turns off, and same cycle again.
All main voltages is presented, except any CPU activity.
Tried to flash EC and BIOS, no success.
there is no visible damage to board, no shorted (hot) smd.
Gonna try to find some info about Boot Sequence, it's tough to check smth because of BGA parts...
Can it be faulty Thunderbolt controller?
