|

I've scanned through the manual (most all is dedicated to menu controls). I've looked through the "Hooking it all up" (FAQ) and can't find an answer. Simple question for those who know. KennyG has posted a procedure here in the FAQ section called "NEC XG G2 Calibration" that says, in part:
10) Set "AKB" test switch to test position.
11) Set your DMM (digital multimeter) to VDC and measure test points TP7404 (red G2) TP 7504 (green G2) and 7604 (blue G2) verify the voltage is 2.5 vdc +/-0.1 vdc...if not try small adjustments of "Contrast", if that doesn't help, call a service tech.
12) Adjust Black Bias to 50 (default) this is just a "rough setting".
13) Set "AKB" test switch back to Normal position.
Which board contains the AKB test switch and which board has the TP7404, 7504, and 7604 test points? Where exactly are they located? Thanks for any help. 
Curt

They are on the Video Out/Gain boards, in the card cage at the rear.
Just measure for now. NO TWEAKING.

Follow-up. What does the AKB test switch look like? Is it labeled? Is it a jumper? I'm going over to a friends house and it would be good to know in advance to keep us moving. Tks.

It's a tiny little switch. Sideways on the vertical circuit board.
