Davidmil, yes ohms. I'm sorry i thought 57 was Q6, after looking at the schematic i see R57. 330.6 is the read out.

If Q6 is R57 then i probed leg E as seen in one of the 3 pics. I actually probed it thouh on the bottom side of the board and pin 36 on the cartrige slot. I get 4.893. I have not cut any other legs per signguy81's request to do so yet. The red probe indicates the E leg, which should be R57. The black probe is on pin 36 in one of the photos.

Davidmil, yes signguy81 posted a link. I see the R57 via Q6, I flipped the board over to follow the trace up to what looks to be a dead end (see pic 3). Now on the other hand with R58 via Q7, I traced it all the way to the bottom of the cartridge slot as you've stated (see pic 2). As for VCC1, I see that point. I think the biggest issue with looking at these is I can't under stand the schematic as you guys do (see pic 1). In the microscope nothing appears to be touching. Sorry for the dirty fingers, I had some work to do and the plane was dirty. I have a couple schematics I use and can understand installing the wiring for switches, breakers, and clean power in boxes, but it's simplified and this is a little more complex. Everytime I upload pics they get swapped around.

To Davidmil, i have checked L7 to ground where the center pin for VR1 was if that is correct and got .931. I also checked L10 to the same ground and got similar results. It was .930. Cart connector pins are not touching and i used an air hose to dislodge any thing inside of it. As far as the VCC1, CI1, CI2, not finding them on the schematic.

May be a delay as i'm busy at work and home. To signguy81 and Davidmil, I'm trying to locate these numbers and have found a few. To answer your first question for now, that has already been tested a few posts back. still 1.2 volts at the connector socket with VR1 removed and the two legs on C43 and C130. Should get a break or two today to locate and test these things.

Davidmil that is correct.

DavidMil, I'm measuring from the Input side and center, which should be ground correct? Pics of what I lifted.

Signguy81 in the pic this is where I followed it to. On the input trace pic 1 bottom side of the board going right and up to the solder point leads to the topside and these. L9 and then runs over to c129 pic 2. On the input side again bottom side of the board following the trace downward, it leads to c37 I think that's what it says and the other which I can't read it's covered. See pic 4. Looks good I believe. Pic 1 got turned upside down somehow sorry.

DavidMil I did not check vcc on on the chips. Q6 4.1 E and B. E and C 153. Q7 4.0 on E and B. 279 on E and C. If I keep the probes there though it seems they would continue to climb. This test is also with the legs still off, I wasn't sure if it mattered.

SignGuy81 there is no game inserted. I lifted legs on c130 and c43 and the input is .938.

Signguy81 the input side with voltage reg out is .972 and output is 290.1, actually moves around from 286 to 290. Output seems higher and input really low. Zylon and Signguy81 the IC is not socketed as you can see in the first pic. Signguy81 is this the cap your referring to? I'm used to the round barrel type caps and this green odd looking one seems to be the closest I see. DavidMil am I supposed to be ohming these two on q6 and q7 with power plugged in or not. I think we are not plugging power back up for now so that nothing gets fried. Sorry for the long delays, i'm busy at work and been seeing a heart doc for some breathing issues. Thanks for all the help.

Voltage regulator 1 out of the board. Input 4.177 output 8.11. Voltage at the power connector on board with adapter plugged in still around 1.2 volts.

In response to crossbow, I got them right here with the power supply plugged into the console. VR1 .791 input 283.5 output. VR2 621.4 input 424.8 output. Each one seems like they're higher except input on VR1 had minimal change. Get back to you signguy81 if I get it taken out today. Thanks for the help guys.

I don't know if it matters, but I checked it on board. Not plugged up. VR1 input .766 output 3.115. VR2 input 574.3 output 338.1.

Here are the pics of the motherboard. any way to test the voltage regular chips?
