For the *almost* seventh anniversary of this story, and because this beast is really crying for it... let's replace the left projector!
On the left, the original projector I got with that theater, remember, the one where the blue was missing...and on the right, one of the spare projectors I got during this two last years :
So I'll use the left one 'Galaxian Theater setup ready' as reference, in order to configure the spare one on the right, used by his previous owner as a 'normal' home theater projector
Note that the model of these two projectors are not exactly the same, but the specs are similar.
Inside the projector...
...see all these pot' ... 2 rows for each color, and some global ones! That's not gonna be as easy as setting up a CRT monitor!
For now, the first thing to do is to setup that projector for a 'cell mount' use, but also more important : does it still work?
Removing a projector on a Galaxian3 Theater6 is 'technically easy', but... you have to disassemble few big elements first, see
I can do that job alone...huh.. so far
Now due to the weight of a such projector, but also due to the procedure to remove it, it's simply IMPOSSIBLE to remove it all alone (of course, I think I'm smart and I tried to do it alone ... but I *fortunately* quickly abandon the idea...
So I'll check if the spare projector works as expected, and if it's the case, I'll continue its setup and proceed to the projectors 'swap' procedure with someone to help me
Let's power up the beast...
The projector works, yess!
Next step, to remove the left 'sick' projector from the Theater, replace it by that spare one, and then starting its setup...
