Re: Apple Imac 27" ? screen ?
Not sure how old your imac is, but in older 2009 and up to 2010/2011 it is related to bad video card.
You must remove the video card (lots of work but worth it) and reflow the video chip.
I believe that there is a recall on some imac 27" 2010/2011
Just check on google which model and serial numbers are affected.

The laptop boots fine into recovery mode. I updated from Monterey to Sonoma and the laptop still has... -

So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on... -
Hi there,
I'm looking for anyone who might have information on Apple's embedded Apple Watch charging daughterboard, ID 820-02601. This is currently used by Anker in their Apple Watch charging products, but likely by other Apple partner brands as well.
You can see the board referenced in ChargerLab's teardown of the Anker Y1811 3-in-1 MagSafe cube - they discuss the "Apple Watch wireless charging circuit" about 2/3rds down the page. It's not pictured, but the board ID reads 820-02601-A, which sure sounds like Apple.
This daughterboard uses an interesting...04-21-2025, 11:41 PM -
