Hi
This weekend I started the arduous task of transplanting the components of a motherboard from my A4000 to a new replica motherboard.
Being a hobbyist and not a professional, but so far things are going well.
I have to keep thinking positive and think I can do it.
So far I have already completed the bottom of the plate and started the top.
The biggest difficulty was the connectors, with so many pins to unsolder.
In the end, maybe it works ...:shhh:

Good luck riri you are a braver man than most.

I was lucky enough to have John "Chucky" Hertell transplant a busted A4K motherboard to a red Acill PCB like yours. maybe contact him if you run into any issues

Hi

After the missing parts arrived, I finished the motherboard, but I still can't celebrate, because everything seems to be working except the image.
The black image appears and I can see shadows if I look in a lower angle. :sos

Regarless the resistor I decided to use wiring to L500 to make L500 do its job of power stabilization even if not really needed :)
