Hi all, our 55oled903 has started to play up today. Philips logo appears when switched on but wont boot up just a black screen. The android loading screen then stop / starts. Then Philips logo appears again as if it is stuck on a loop. I have downloaded the latest firmware to a usb but still nothing. Everything disconnected (firestick etc). Any ideas? Fingers crossed not a major fix as the tv is only around 3 years old.
