After some research, I've identified it as a "common mode choke". This particular one has 6 pins (legs) ie. three lines.
The dimensions are roughly 4.5mm x 3mm x 2mm
I couldnt seem to get consistent results when mesuring resistance, but somewhere around 4Mohms

I've looked every where online but cannot find an exact match so I may be forced to shell out for a spare logic board from eBay
​On the off chance anyone may know where I can source them from, please let me know,
Thank u.

2017 iMac (Mid 2017) A1418

I'm not quite sure how this happened but a couple of components got ripped off the board when removing from the Logic Board from the iMac.

Can anyone help identify them?

I'll have to do the trace repair on the board before soldering on replacements but would prefer to order the components rather than get a whole scrap logic board off eBay.
Thank u

Hi,
Ive got a weird problem with a Water damaged MacBook Air A1466 ( 820-3437-B )

After ultrasonic cleaning and fitting a new DC-in board everything seemed fine.

- The board passed all tests in ASD EFI 3S156
- But it would not even boot the ASD OS 3S156 - it just freezes on the spinning wheel loading screen
- Booting into macOS goes to a black screen with a mouse pointer but no further
- Booting into macOS safe mode works just fine.
- Resetting SMC & PRAM makes no difference

last time I tried booting into a Sierra...

Re: Quanta R22 (HP G6-1001sa) no power

Hi,

I replaced PU3 (the 5V/3V source) and still dont have any 5V or 3V.
I also changed PQ40 and PQ42 which are mosfets on the 3V and 5V rails and no help.

I guess its not that surprising as there were not shorts to ground on either of those rails.

Has anyone got any idea what it could be?

thanks

its RT8223

Re: Quanta R22 (HP G6-1001sa) no power

I just found pins 20 & 21 on PU3 are shorted together.
I guess that confirms this is where the fault lies?

Re: Quanta R22 (HP G6-1001sa) no power

Thanks guys, im going to order a new power IC and see if it works.

Hi, I have an HP G6-1001sa with Quanta R22 motherboard DA0R22MB6D0
It has no power LED.
The 19V Vin is present.
There is no 3V or 5V, however neither of these two rails have shorts to ground.
Ive checked MOSFETS like PQ39,40,41,42 and no shorts.

My knowledge is limited so I am not sure what to check next?

Also does anyone have the boardview file for this motherboard?

Thank you!
