What position do I check voltages for that and on what settings with the multi metter and do you do it with the red or black never done this before sorry for noon questions
Depends on your multimeter. If it's auto-ranging, set it on DC Voltage. If it's not auto-ranging, set it on the DC voltage range just greater then 30V; this will most likely be the 200V range (ranges are commonly 2, 20, & 200).
Find the chip on your PCB. With the game power on, CAREFULLY put the meter probes as shown in the attached diagram. Note the "notch" circled in green, which shows you which end of the chip is which.
Also, the period key on your keyboard is often located just below the "L" key. Use it to seperate you thoughts into sentences. It'll make reading your posts easier on the rest of us.
EDIT: Some chips, instead of the "notch," have a dot by pin 1 to indicate orientation. And yes, both the black and red probes need to touch both pins at the same time. And don't sweat mixing up the red and black probes; it won't "fry" anything, it'll just reverse the sign (+/-) of the reading. The only ways to potentially damage things are to (1) accidentally short out things (like the -29V line) to something else, or (2) use a DMM mode which has low impedence, such as current mode.
