Right! Lol Tx

Probably will. Yes but wondering if replacing the Cap will work.

Hi I have a early 2011 MacBook Pro 2011 goes through book process and all works until it gets to last screen which is BLANK White. I tried a different drive but same result. Im going to replace the tangent capacitor but has a different number then previous on. I am going to replace with a...

Yes correct memory. Measuring .772 volts

Hi, I have a 820-2915 doesn't pass post getting 3 beeps. Changed memory tried both slots no good. I plugged in usb mouse and it gets a light after I start machine. Any ideas? Tx

Heat Station 150 degree C

Thanks Duke, Board Fixed! Thanks!

Hi Duke, I need to test again but I believe you are right the battery didn't have any juice so it was charging. I did notice it won't start just with power supply plugged in and no battery. Machine charges fine and starts off battery.

Hi Duke, When I startup the machine everything works but the board gets hot neat the processor. Ill remove the chips first comparing boards Clean the board and try again. Problem is I pulled chips off the second board so I don't have a great comparison but Ill give it a shot. Thanks as usual!

Hi Im working on a 820-3437 board I have a second board to compare with. Schematic says there should be a chip in certain location but second board matches first board with no chip there? Am I correct in believing the second board? In the U5000 Group Example R5445,5475 If it runs hot when I put...

Ok I get it now Tx as always!

Thanks Nate! I have been adding parts for 3 days now. I now need to go back and double check my work. On the bright side it has been good practice. Around the u5000 chip

Hi I looking at 2 logic boards and there is no component on both boards for the same location. Are the Schematics always correct? I also search for a substitute part. Says should be a capacitor but its black and not grey. I see many places on board that look like components could go there on...

Hi Jadao, Thanks for the info. I didn't see the part I was looking for on Louis's site and Louis recommended them in one of his video's as a source.

Agreed but to much trouble to search a board for the right part and again and again. I need several of this resistor so easier to replace the most common ones with a new one. Use the boards for when I just need 1 part. Thanks for your info much appreciated

Hi Im working on a 820-3437. R5475 4.53k This is a non current sensing resistor? Need to replace some resistors. Probably blew away don't know. I assume I should order from mouser? Does anyone have their part number? Thanks

15" 1398 etc 2674 i7 2ghz Sorry 820-3662 Late 2013 Searched for U8900 couldn't find on board view.

I have a 820-3547 EMC 2674 15" MacBook Pro 2012 not booting MOST of time.Sometimes machine will gong and boot but rarely. When it does gong reset smc and pram 4 times. Fans spin no gong no video. I suspect failing GPU. Is there anything I should check before calling this one not repairable? I...

Got it now cause I know what the resistor looks like now. Your right quite a few on parts board. Thanks Much Duke!

Thanks Duke! Machine is up and running. Doesn't look pretty but it works. Had problems soldering the resistor on but used the heat station with the air flow way down under 20%. Now I have to clean the board and put it back together. Still praying all is well. Thanks Again!
