Your Guider's motherboard has packed in and the printer won't even post. Before you write it off, this is the exact replacement PCB for both the Flashforge Guider II (TL4240) and the Guider IIS (TL4239). One important thing: the hardware is identical between the two models, but the firmware differs. It ships pre-installed on the board. If you swap it in and notice a function like the camera or Polar Cloud is missing, do a manual firmware update for your specific printer model. $599 RRP through Jaycar. Add to cart and get back to printing this week instead of next month
