Hello,
There is no schematics for this board.
This the backlight coil. The ip -
Re: ipad pro A1701 missing component
You can compare with ipad air schematics.
I think the coil you are searching is L8225 (PILE051D/4.7µH-3.4A-0.075OHM) on ipad air.
Check the diode on the right it can be damaged.Comment

Please see attached. Coil is p/n LF8425 = 10uH - 2.55A.Attached FilesLast edited by mon2; 08-24-2021, 05:12 AM.Comment

Re: ipad pro A1701 missing component
Any chance you might be able to tell me the value of R1850?
I was reballing NAND and had R1850 come off. Afterward as I was putting it back in place my boss starts yelling my name (FOR NO FUCKING REASON!!!) distracting me for half a second, and that's all it took for it to disappear
Thank you very much!Comment

Re: ipad pro A1701 missing component
See attached. This is from an ipad PRO schematic - hope it is the same for your logic board.
That is one tiny bugger - DK / Mouser / Arrow should have these = 01005 SMD size ? (OMG that is tiny)
DK has them:

sorry to dig up this old thread, LF8425 = 10uH - 2.55A but mine measure around 4.4x4.4x1.3mm.. what package size is this? it doesnt seems to be 0420 or 0520?
Also, for L8101, I saw it is 0.22UH-20%-7.0A-0.018OHM, it measured 2x1.6mm, I guess that is size 2016 or 0806?Comment

I tried searching the forum for whether this has been uploaded already, but couldn't find them (as a collection).
Here's a dump of a bunch of iPads, I've split into 2 archives to get under file limit

Manged to get a hold of an iPad Pro 11" 4th Gen however it does not charge and upon opening it looks like someone has tried to replace the port and knocked a component off but I cannot find a schematic or boardview for this model so was wondering if anyone could help identify what I think is a missing pad and capacitor? Looks like whoever was in here last tried to put it back on with hot air and melted the plastics too...... -
Hello,
I bought an iPad 4 from eBay which is not powering on and wanted to troubleshoot the problem just for fun.
But the fun ended when I stuck... I don't know what to do next and I'll be thankful for a bit of help.
What I know so far:
Pluging the iPad to the charger charging the battery with around 2.3-2.4A, which is OK IMO.
Pressing the power button does nothing. Press and hold the power button + home button (to reset the device) does nothing (it is resetting but still doesn't turn on).
I dissassembled the tablet...11-19-2021, 04:46 PM -
Hello, I am looking for help to replace a damaged diode. The tristar was replaced and a diode was damaged in the process. I have a picture of the diode but dont have an exact donor. I mostly have macbooks for donors and only a few ipad and iphone boards. Diode part number: DSF01S30SCAP
Im not sure where to find the ipad board number. Anybody have an idea where else this diode is used on other boards? Thanks.... -
Hello to all,
I have a missing voltage on this ZOTAC GTX 1050 TI mini card (circled in blue)
I have all my other voltages strangely but the missing one goes up to 0.04 V and measured in Ohm 45 Kohm I find that really high and I expected much less than that.
0 SHORT circuit on the rest of the board
GPU heating and voltage at the coils 0.80 V which is normal for this type of card logically.
Without a schematic it's quite complicated and long to look for.
Do you have an idea?
I checked all my components seems present and checked...
