Unfortunately, my M550 needs to go back to Acer for repair again. Since going to firmware D02, 24p content doesn't display correctly (as previously discussed) and I've recently got a white spot on the image - I'm guessing it's a failed mirror.
Can't thank you enough Steve. All working perfectly now. Now just an exercise in hiding the tangled mess of cables and getting a power solution for the Pi3 Zero. Ordered one of these to power the PiDid you also connect the null-modem cable between the serial cable and the projector?
I had a failed mirror. Check for dust when it comes back (defocus the lens as they come in to focus at a different point to the picture). Mine was terrible, twice.

I did put in a long RS232 cable to my media centre when I did all the cabling but would need to try and reproduce the USB-to-RS232 with null modem combo. Sounds like another fun project

Thanks Steve. I will make sure to look for them when it's returned. How long did you repair(s) take?
As usual a huge thanks Steve. I would have followed your advice had I read it before but looks like I got away with it and the Pi Zero is working well with the dodgy power supply. This is the only thing the Pi is being used for so it's under no real strain. I checked this site before I bought it and it looked OK maxing out at 230maNo problem
About that power supply, even for the Zero I would be looking at 1A minimum and if you have any unpowered USB peripherals then maybe more.
This works well and is great value:
Raspberry Pi Official Universal Power Supply - 5.1V 2.5A (White)
I run 9 Pi's around the house and the only problems I really get are due to insufficient power.
Well after over 4 weeks away for repair my M550 finally came back from Acer.... with scratches all over the lens and dust in the light path. Completely fed up and their terrible service. Fortunately, Amazon have agreed to refund the projector based on the experience and I will now order the Benq W2700 when released.
To summarise - The M550 is a great projector (with some known issues) but the service offered by Acer is terrible.
This was the reason I first sent mine back. Research showed it might be the bulb, which I believe they replaced. I also bought a new bulb myself from China for a very good price (£55) in case it started flickering again.Mine just got sent back to Germany with UPS( AGAIN!!)
ECO mode totaly flickering !
