Thanks, but still not working for me!
I'd appreciate you telling me what I'm doing wrong and/or how I'm misinterpreting your instructions:
With the Optoma HD25 projector running, using the Optoma remote handset (supplied, small cream coloured bone shaped remote control, type A. Not black remote control, type B/C), I press the following keys ONCE and individually, (I,e I do not hold down any key while pressing a second key), as follows:
1. The OFF key (the power off key top right on remote)
2. The UP ARROW (marked Volume+).
3. The DOWN ARROW (marked Volume-).
4. The MENU BUTTON (immediately to the left of the Down Arrow).
I have tried numerous versions of this, (for instance, excluding item 4, or reversing the order, trying left and right arrows etc) but nothing works. I have tried it with and without a HDMI lead plugged in, Although I can't imagine it needs an active source present to bring up a service menu... So am a bit stumped. If you see where I'm misinterpreting the correct sequence, then let me know! Just to emphasis. I am only pressing each key once, I am not holding two keys down at any point and I am pressing them in the order given above.
