Since camera error is included, I disconnected it and no more high fan spin. Gonna run ASD again without it.
Update - With camera disconnected, no errors thrown. Bad connector ?
Update - Connector looks...
Hey Duke!
Donors came in for this today. Swapped SMC, and everything seems OK. Which Im very happy it is, cuz Im been getting raped by these boards so much lately that my next post may have been my fucking suicide note! :D
Have a good one man.
I kind of think its something to do with PCH because when I cleaned flux from kb connector I may have gotten solution under it. Before cleaning, everything worked. I have a ton of 2915s with dead GPUs. Can I swap PCHs from a dead board with hot air station and maybe heat gun for bottom heat...
Computer shuts down from cold boot after about a minute of running. This seems to happen in shorter periods of time once the first initial crash happens if i keep rebooting. I have changed RAM and tried different slots. Also unplugged all peripheral besides LCD. No Liquid. Is this a known issue...
Hello Duke.
Measuring on both sides of L7510/20/30, Vcore doesnt show at all. Not even the slightest movement on multimeter.
Resistance on Vcore is 10.8 Ohms.
U7400
Pin 1 (CPUIMVP_VR_ON) cycling 3.3V
Pin 2 (CPUIMVP_TON) cycling 11.68V on pin 1 R7402. Pin 2 R7402 is steady 12.56V. <-----------...

I appreciate the help. I feel like a shit head over this...
To answer your questions... Yes, I only have a multimeter to check. No scope at the moment.
I do have an Ultrasonic, but Im not sure if I can trust it. It is a 180 dollar True Sonic. Havent used it much because I was suspicious...
SMMRepair
Nah... i always blow off alcohol with high air from compressor and under BGA's. Then hit the board and under the BGA's from bottom of board with hot air. Usually works fine, LOL. Its not like I just got lazy and decided to plug it in wet! I will check in AM, SMMRepair. Thanks for your...
hi.
So I got this board cheep but working. Just needed some touch ups (KB connector, SPKR Connector) . So I carried out the deed and everything was OK (booting/chiming). I proceeded to clean the areas that had flux left on them with toothbrush and warm water/Branson mixture. Then dipped those...
I am looking to buy a used oscilloscope that doesnt come with probes. The model is Aligent 54621a. I cant seem to locate. Are other ones/generic interchangeable?
u7100 had burnt pin (20). I replaced it. Both sides of L7101 and L7100 start at 72 Ohms and drop very slowly. I held it for 3 or 4 mins to about 60Ohms then took probes off. I think it would have continued to drop. So maybe a small short? I dont have a donor for this... Do you know of any other...
The only part that was damaged physically on the board was J4915. That leads to5v_s0, could that be fucking up S3?
?
This board is so clean I dont even know where to start. No shorts, checked all 1.5V/1.2V/1.8V/1.05V RAILS.
Home now with 3 screaming kids on their vacation. Get to it in AM. Just wanted to know where to be checking.
thanks for the help.
Have a good night/day.
Hey Duke.
Nothing on 5V_S4.
S5 going into U8060, .011V on 5V_S4_EN
Will check other things next.
Thanks.
Update-
Areas recommended check over and clean. Board is very clean. All TP's are still gold. No visible burnt traces or damage except for what I already specified.
Will check for...
Hey Duke.
Noticed pin 20 on U7100 was a bit burnt. So I replaced it, along with C7196, C7126 and R7120. I would have replaced the FETS but I do not have a donor for this. Is there another board that uses these I can pull themm from? I also replaced U7200 for the second time.
I Now have...
Liquid damage on J4915 and has been removed for now. Also C7778 was damaged and replaced. No other visible damage.
