hey guys I could use a little help. I'm trying to determine the pinout of this zenith monitor's rgb port and I've found this 2A5/5A2 cable between the main module and the neckboard which shows it having the reg green blue signals, but my multimeter is only getting a reading from the leftmost pin, and it shows up on both pins 14 and 15 of the input.
Can anybody tell me where on the circuitboards I should check to find the right pinout?
