Hey guys...
I purchased a couple of inexpensive Chinese made RGB projectors off of Ebay a few years ago. The scanners have never been tuned optimally, but now they have drifted to the point of being unacceptable to me.
This is the item I got...

Unfortunately, they didn't come with any schematic for the amps showing what pot is which, so I'm sort of flying blind here.
What I have figured out is that the twelve potentiometers in line are a "mirror" of the other channel. For example, the pot on the far left is the horizontal position (offset?) and the pot on the far right is the vertical. It will make better sense when you look at the photo and see how I've labeled them.
I have thus far been able to label the position, size and gain pots, but I'm unsure about which are the high and low frequency damping, and then I'm unsure as to what the additional pot is for each channel.
Does anyone recognize this projector and/or amps that can direct me to a schematic? If not, how can I determine what these other three pots are on each channel?
Thanks reading and for any help/advice!
