might you be able to tell me what these numbers mean, so I can replace it? thanks

for anyone curious, I found used Weller wmrt desoldering tweezers and used compatible base station on ebay for a total of about $350

Is this possible? I have the hakko fx951 but it's not compatible with hakko's tweezers. I've seen portable units under $100 but they're not designed to handle very small smd's. has anyone tried using two soldering irons? thanks for any help!

I have about a 75% success rate finding one on the web. I subscribe to Vinafix, and sometimes I find one for free. Is there a definitive resource that lists/knows if something is available and when to not waste time looking? I'm a monthly subscriber on this forum--is it ok to ask here if I can't...

thank you, I'd like to think I would've done that if I could positively identify components on this board without the schematic/.brd, basically blind right now without those. Some areas of the board are the same as 820-00034, other areas like the LCD are not. I'll inspect/repair/replace the...

ok, here's the condensed complete history purchased this 2017 21.5" iMac, A1418 non-retina with a firmware lock I reprogramed the efi chip, and tested all functions worked including display and all good then I cracked the display trying to remove the old adhesive, @#$$T purchased replacement...

damn, I'm using 820-00034

never mind, I plodded along and searched through digi-key long enough to find what I was looking for "RES 0.05 OHM 1% 1/16W 0402" ?

I found another board's schematic/.brd that is essentially identical, and narrowed down the problem to resistor R8104 which is supposed to measure .05 ohms but is actually resisting at .4 ohms. It's the only component between the power supply and the 12v input to the LCD backlight driver LP8561...

thank you good idea, I think I found the datasheet, I'll post back asap

in your vast library, by chance do you have the boardview file and schematic for iMac logic board 820-01069 that you would share? having a devil of a time finding it. 2017 21.5" iMac, non-retina, known working display and eDP cable, external image works, I don't get LED #4 (i.e. board not...

2009 MacBook Pro back light fuse orientation? hello, I am repairing a MacBook Pro 2009 12 inch back light issue, the previous fuse was removed before I received the MacBook, it does not look like there’s any left or right up or down or pin #1 etc. Can you confirm whether it matters which...

hello, pad/hole for a headphone jack pin on an asus motherboard; this isn't a mac but it's general soldering so i hope you don't mind. does the pad have to be a closed loop or will this suffice?

After much micro-soldering practice, i finally went for it and purchased an iMac at a deep discount that would require replacement of the 60-pin DisplayPort connector, and hopefully flip it for a profit. I tried it twice, and each time the screen wouldn't even power on, and only the first two...
