I would ask You about an Android OS in Philips 55PUS6561/12, which doesn't boot a system after shows Philips logo (black screen, no reaction on remote control, LED notifications pulses).
I think it can be a problem with some bootloader in Android, so I searched about it and found tips like: ABD / fastboot, but it tells me nothing.
Can You give me some exaplanation, how to check / solve problem with this TV? Regards!
