Hello, this red blue blinking pattern means there is a problem with the power supply.
35W is not enough to run the projector. You need around 65W for full operation and at least 48W to run correctly at all. 15V 2.5A is the minimum recommended spec for third party power supply, if you want to charge while powered off. While powered on, we recommend at least 4.5A 14V supply. This will supply enough power to run, but the charging will be quite slow.
For the best results, use the included power adapter or a similarly spec’d USB-C PD adapter, and charge it while powered off.
