I can buy these diodes here in Canada, and get them faster than from China of course. Would a 1W diode be appropriate in this application? http://vi.raptor.ebaydesc.com/ws/eBayISAPI.dll?ViewItemDescV4&item=183650841004&category=181899&pm=1&ds=0&t=1552801163871

It turns out that the 6.8V multidirectional diodes are not a replacement for the 6.8V Zener diode. Well, if nothing else it was good exercise in removing diodes from the donor boards. I added leaded solder as I removed them from the donor board, at least they cannot get away that easy, and I...

Yes, I was quite frustrated and had to call repeatedly on my infinite patience.Thank you for letting me know that I am not alone in finding this super tricky. The tiny bits either flick away or get stuck to the iron. I will educate myself , there must be some youtube channel that discusses how...

I tried and tried,but could not get any of them to stick. I think I will have to wait for the monster zener diode with legs aka pins to arrive from China. I really suck at tiny soldering still. Must watch more videos on it, I suppose....

I finally have some time and I am setting out this morning to transplant the 6.8V diode from my A1286 donor to the MBA. Just wondering if you would help me clear up a bit of foggy understanding as far as orientation goes? I suppose I can determine the orientation of the diode I will harvest by...

Thank you JohnB8812. So in your opinion fresh Arctic Silver will be a waste of time? I think I read somewhere that the thermal paste tends to dry up after a few years, and that more recently developed pastes dissipate heat better...Just wondering if I can extend the life of this rig....I...

I looked on some of my donor boards for a diode, and found plenty with the 6.8V designation on the A1268 board. However, the symbol is different. The one on the 00165 board has one triangle pointing away from ground towards the horizontal bar. All donor board diodes I have seen have 2 triangles...

Thank you . I will check out your link asap.

I just replaced the cap, and it boots OK after some struggle, which I resolved with SMC and PRAM reset. Also replaced a corrupt HDD with a good one. But there is still too much heat according to HW sensor: Up to 94C in CPU1,2,3 and 71C at PCH. I checked the heatpipe as far as visible with board...

Thank you for all your help, it is so much appreciated. And yes, the tinyness of the components are a real challenge for me, but I am determined to learn how to do it, if it is the last thing I do. Largely my shakiness is from excitement, it is all so new and mysterious...but I am learning...

OK, I will order some of the diodes you pointed out SOD27 (DO-35) from Mouser. If you have any suggestion what other components are used frequently in Macbook repair 2009-now, I could order them all at once...Must read up on what the diode designations mean...I am without the faintest...

I am checking R7010 and R7011, both have correct ohms...Do not know how to test Cap C7012

My Q7010 looks different from the boardview graphics, which shows 4 Pins called 1,4,5,6 in a different arrangement then what is on the board. On the board I have an 8 point component. Looking at the board with the fan/DCin board on the right: Q7010 with its 8 pins ( 4 each side) has 15.1V on the...

So I found a 68k resistor here locally, not an SMD, but one with legs. I am improvising, to make up for my shaky hands and still limited soldering skills: I attached a copper wire to P1 pad of R7012 attached my new resistor and grounded it to a convenient ground in the hood. Made sure the...

One more question regarding that 68k resistor. How critical is it to get ALL the sub specs right, namely 1% 1/20W MF 201. I have a donor board ,an A1286, which has a 68K 5% 1/16W MF-LF 402 on it. Also have been looking on ebay where I can get carbon film resistors rates 68k 1W +-5% . Those...

Thank you for your patience and for taking the time to spell it out for me. Very much appreciated. I have a good microscope,the flux is the brand Louis recommended, but the source was Ebay, which is according to him not good enough...Anyway,I will order the real flux from Amtec and will find...

I hate to admit it, but I screwed this up. I just could not find a way to hold down that resister while soldering the ends, it kept sticking to my tools, just too tiny. Then I tried to use hot air, I did not get it to stick either, lots of flux, but no cigar..Finally one end of the resistor came...

Cool, great learning curve, thanks so much R7180: 99.2 k R7181: 61.8 k R7185: 474 k R7186: 333 k R7012: OL I have R7012 on my donor board reading 68 k !!! Anything I should know to safely remove and install it on my good board?

The good upshot is that my tea damaged board can serve as a donor now. While completely corroded in some sections with caps green and falling off, the PPDCIN_works on that one , past Q7110 up to D7005. I am about to confirm the ohm measurements for the resisters pertaining to the mosfet Q7010...

OK, plot thickens!! I just tried both Mag2 chargers on the other tea-damaged 820-00165-A ( I will call it board 'T') , and with both mags I do have 14.9V on the two relevant J7000 points. This means that the chargers must be OK after all, but somehow do not register on the original board I am...
