ColorLock hardware questions - m_emelchenkov - 10-26-2018

- What value of capacitor installed in ColorLock?
- What correct order of color filters?

Electronic circuit diagram of this device will also be useful to me.

Does anybody interested in it at all? I have two now, and have plans to repair first based on working (I hope so) second.

Could you supply more information, like some photographs of the device? It doesn't sound like it is a SGI product, but a device from a third party company

I think he's referring to the calibration 'dongle' you get with a 1600SW screen:

Is this the O2 colorlock for tge 1600SW. I have one but it's mint and not willing to open it, sorry.

JacquesT is right. That is:

In the interest of scientific investigation, I've taken my CL apart

But I need some help, in what order do the three filters go back? Mine fell out. 

I only have a very simple multimeter, not sure I can measure anything on this? Let me know and I will try.

JacquesT, oh... now you should wait until I'll disassemble my own. Very simple multimeter can't measure capacitors. I have two special measurement devices for this. I planned to return to this topic in next 6-10 months, that's why I asked if somebody interested at all, should I publish here or not (after Nekochan dead I was unsure about aliveness of this forum). But if you lost proper order of filters, that means I try to schedule my processes regarding this device earlier, shifting other tasks.

No problem, it's been in my drawer for 4 months and not used. I only used it a couple of times then put it away. Let me know otherwise I'l lput it back together and try and sort out the filters...There should only be few possible solutions, one of them has to be correct.

Edit - the Colorlock works fine with filters placed orange (red) closest to aperture, then blue then green.
