ok..I read most, not all of this thread (and others and watched youtube vids)
...and I have a stargate with no sound but WAS playing...then one day i turned it on and got the 1-3-1 error (which from reading online is a common error)...BEFORE i got the 1-3-1 error on the stargate i did replace the sound bard with a working one and i did get sound....so for stargate sound problem it is definitely just the board itself and nothing else...as far as the 1-3-1 ive done all troubleshooting i can think of (with my limited knowledge) and i still get it 1-3-1.
I also have a sinistar that plays but no sound...and again...put in working sound board and got sound.
For the stargate i have replaced the 1-3-1 error chip with others on the board and I still get the 1-3-1 error...you know..the swapping of positions routine.
I have had someone walk me thru (over the phone) testing the voltages on the stargate and all spots tested were within range to be considered receiving enough voltage in all test areas.
But I need to ask....can someone do a detailed step-by-step video of EXACTLY how to use a logic probe to trouble shoot a board/chip?..I read what you guys/gals post...and i appreciate it greatly..i really do.....and I know it is a lot to ask, but a vid would help me and others out so much...and ive done all the youtube/internet searches on the subject....but still in the dark on it...Every vid i've watched is vague...."this leg is reading high......this leg is reading low...etc..etc".....then the vid cuts away and resumes "ok...i fixed the chip that was reading wrong....it works now....bye..thanks for watching."....makes me want to pull my hair out....HOW WAS IT READING WRONG??!!,,,,WHY WAS IT READING WRONG??!! hahahaha....drives me crazy.
I'm always left asking to myself: what is high??.....what is low???....what exactly is what??? how do know what each leg is supposed to read????....if a leg is reading wrong, how do you remedy it??...how do you tell a leg is reading wrong??....the logic probe beeps..lights up.....where do you find out which leg is supposed to beep at what level??...green lights up on probe??..red lights up on probe?? What what what?!?!....It's just nothing is exactly clear to me....I read up on things but i need to physically see it being done start to finish: Here is the chip to test...here is where i find out what the legs are supposed to read....hi means this...low means that...if its supposed to be "low"..and it doesn't read as such, then we have to do this......etc...etc.
I dunno..i guess im venting my own frustrations within myself for not grasping everything as quickly as i think i should....i have two games i cant play and its driving me bonkers....ive multimetered the life out of both of them.....resolders the headers....i bought the logic probe as "the next step"...but i really am lost on it.
