Hi everyone, Since I started getting more and more water damaged macbooks I want to make sure that I give it back in fully functional order. What I used to do is check manually keyboard, sounds, wifi, run for couple hoours. But it failed me another day with 820-00165 when I did all the regular...

J6100 doesnt have any visual problems with it, I removed it nevertheless. Macbook works fine since, I run it now for 3 hours, doesnt have any issue, I am hesitant , but it works, I will keep testing. Thanks Duke!

I had 3.4v on SMC_RESET after U5110 replacement. After reballing SMC I get the same thing. Macbook turns on and shots down every 2-4 min. Light turns green when it turns off. One time it stock on green light and will not turn on SMC_reset was 3.4v no flexes connected to the board. In what causes...

I removed smc and re balled it, not difference.

Thanks, unfortunately disconnecting track pad flex doesnt make any difference, as well as there no corrosion that I could find. Can it be smc it self since U5110 close to it and could get hot

louise, U5110 look fine, there is no signs of any kind water damage. R5100 is fine. I replaced U5510 (SN0903049) with SN0903048 from 820-3209, pin out and signals look the the same on the chip. I got 3.4 on SMC_RESET I got green/yellow light. Macbook turns on BUT i have new issue, not sure...

SMC_RESET_L - 0.4v - it should L? or I look at it a wrong way? PPBUS_G3H - 8.2v

Hi everyone, I just want to confirm that I have a case of bad smc? as I mentioned before I am in a remote area so it is a big deal to order parts. So I hoping someone can confirm that I have smc issue. 820-3235 - no green light not water damaged. doesnt turn on. PPBUS_G3H - present PP3V42_G3H -...

I bought 1080p 60fps camera from Amscope. quite expensive, but qulity is nothing like on Louis's videos http://www.ebay.ca/itm/1080p-HDMI-Di...EAAOSwSzdXA~Ih and this lens: http://www.ebay.ca/itm/AmScope-RU050...IAAOSw5VZXA-FH I also have 0.5 reduction lens I uploaded my first video...

There were no corrosion in areas you describe. I will let you know when it stops working next time.

​ Hello everyone, I really hope some can tell me what to do or what could be the issue. I have macbook air which I fixed after water damage for resale. I inspected board carefully and the only corrosion I found was in R7006 area, 4.7ohm resister was bad. I replaced the resister and machine...

SMC_RESET_L - is high (3.4v), I didnt find 820-2879 for reasonable price on ebay, But i do have 820-2936 that I got from ebay for $30, it has the same smc code, so I tried that on my board since it looks like last chance for repair. After replacement of SMC few things has changed. green light...

I gave the voltages in my first post. nothing was changed , Louis kind of confirming that my smc probably bad and I asked if it is as simple as installing new one, or I have to flash/reset anything.

820-2879 is the right number, so after smc replacement do I have to flash anything? I dont have much experience with macbooks, but with regular laptops I need to flash it some time when replacing multi-controller. is that the case with macbooks?

is there reason why I dont get any answers?

I got this board no green light, I figured out that SYS_ONEWIRE was missing, then realized someone already blasted smc with heatgun, I reballed smc, SYS_ONEWIRE returned. PP3V42_G3H_ONEWIRE present SMC_BC_ACOK 3.3 ADAPTER_SENSE 2.8v Still no green light, now figured PP3V3_S5_REG missing...

Doesn't have any water damage initial apple logo screen has small discoloration. Right before finishing loading bar , colorful line flashes through the screen about 1/2". after that grey screen tech 5 second pass it restarts and all over again. It doesnt but in internet recovery, restarts on...

I got adapter, there is no external image. I put in bootable harddrive, macbook chimes, I waited for awhile, no image. So you think it is gpu? I am not confident with this conclusion, because some laptop require LCD detect for external monitor to work. (non apple)

Well since you asked to come back and check for external signal, I decided to make sure that my adapter works with working machine, and it doesn't. I reordered on, should arrive on monday. Is there something I can do without adapter? what is the conclusion if I get external image? defective...

Duke thanks for suggestion, but I have checked LID before, it is high, 3v3 U9000 doesnt have short, however one thing is strange. Pin 3 has low resistance to ground 0.565k, 0.122 diod mode. I still get 3v3 volts there, while screen pluged in. I dont have other 820-3330 motheboard but I compare...
