I've had a replacement for the projector board from issue 27 as once built the projector wouldn't work, I have replaced the projector board but I still just get a white circle with no projection, has anyone else had this and managed to find a fix? It worked fine when tested before finalizing the build.

Check the cables in the main board located in the dome, particularly the mic and camera sockets.

Also, it can sometimes take a second or two for the image to appear.

Thanks, I have checked all the connections in the head, disconnected and reconnected, can't remember which one the mic is, the camera is a ribbon connector and connected and working fine. Still no luck with the projector though

Did you ever figure this out? I just finished issue 100 and have the same issue. I swear this tested out fine. I think there may have been an issue where the image was inverted or something odd, but it definitely was not just a circle.

Thanks in advance,

Mark

Sadly not, I did (eventually) get a replacement projector board but that made no difference, so no idea why this is happening, only thing I can think of is the connection from the main board in the head but it takes months to get replacement issues!

A very common issue for this is the ribbon cable from the screen to the main projector board becoming dislodged during transit. Where the cable attaches into the socket on the board, very carefully flick it open (look for vids on youtube how to disconnect a ribbon cable) gently pop out the ribbon and re seat it again in the socket, ensure it is fully located and close the locking bar back down. This solved many of the problems other people had

I am also amongst the many that have a faulty projector. Having tried all the ideas presented in this and other threads, I ordered a new one. They claim about 3 weeks but it could be months. My question is, can I finish the model and still be able to replace the projector when it comes or should I put a hold on the assembly once I get to the installation.

This is a quick build and I could be ready within a few days.

Thanks in advance for advice.

I would certainly hold back on finishing the dome section where the projector is placed. Fitting a new one would entail dismantling some of the parts if you choose to complete it. Personally I would refrain from handling the main board too much, in case any damage is caused by unplugging cables that are attached to it, but that would be your decision.
