Tonight is my first time seeing a purple colour on power up. No way to gracefully return it back to normal. i recall before this happens last time when I power down/standy, I see vertical/diagonal strips.
It's not an coincidence. The end of the strips indicates the beginning of full purple screen. It really says that the chips in 9700 (the chips are very complicated these days) are programmed into unknown states. Hence, incomprehensible colour/pattern.
To workaround my purple screen, I unplug 9700's power supply. Wait for 5 minutes and connect back power supply. Bingo! 9700 returns display back to normal. It works because unplug power truly resets chips to normal states. While standby, you still have electricity powering the chips.
I would suggest Philips analyse 9700's firmware to iron out such bugs. Focus on chip initialization/standby routines of the firmware.
