@Philips_Support_P

If your PicoPix Max doesn’t power on, or it shut down while using it, follow these steps to identify the issue:

Check Power Adapter and USB cable

• Are you pressing and holding the power button (on the projector or the remote) for a few seconds? Yes
• Are you using the supplied power adapter and USB-C cable? Yes
• Do you see red/blue flashing LED on plugging in the charger? This means the power adapter you’ve connected is not supported. Please use the supplied power adapter. No

If you’re using the supplied adapter and cable, continue to the next section.

Check battery charge status

• Make sure the projector is powered OFF.
• Connect the power adapter to the projector. Make sure you plug it into the right side USB-C port (charging port), not the left side (video port)!
• Does the LED turn red? If yes, let it charge for 3 hours until the LED turns blue. Then unplug it, and power it on. Does it work? It charges for 20ish mins and turns to blue
• If the LED doesn’t light up at all, check that:
  • the adapter is receiving power from the wall socket.
  • do you have another USB-C device? Can the PicoPix adapter charge that device? If not, the adapter may be faulty.
• If the LED lights up blue, it means the battery is fully charged. Continue to next section.

Check display problems

If your projector can turn on but doesn’t display any picture, check this as you power on the projector:

• Do you see the white Philips logo startup screen? Yes
  • if yes, but there is no picture afterwards, check that all cables (HDMI / USB-C) are unplugged.
  • does pressing the home button on the remote or touchpad causes the home screen to appear? Yes
  • does pressing the autofocus button on the remote show the focusing screen? Yes
• Does the projector power off shortly after showing the home screen? It could be a thermal shutdown. check next section. No

Thermal shutdown

If you don’t see the Philips startup screen, or the projector powers off soon after starting up, check the following:

• Do you hear the fan spinning up when you power on the projector? Yes
• Do you have at least 30 cm free space on all sides of the projector to allow free movement of air? Yes
• What is the altitude of your city? (the atmosphere might be thin!) *Bol, Croatia ~50m
• What is the room temperature where you’re using the projector? 25°C
