Question about XGIMI Mogo Pro+

The light is red and when I switch on the device it flashes yellow, but there is no picture. However, the ventilation is running and when I connect the device to the TV via HDMI, it says that the device is not switched on, although it is flashing. However, when it is switched on and no picture appears, something happens in the lens. The manufacturer says it's a hardware fault, of course it's only since the warranty has expired and the repair would be 155 euros.

Can also be operated with electricity. If it works like this, then it is due to the battery. In this case, the reset is performed with the power button.

If it no longer starts, it may be the power supply, as it should normally start without a battery. To do this, look to see if you have a light on above it. It is also possible to change the battery, but you need to know a bit about it. There are tutorials on the internet.
