Not of the screen.
The motherboard with the pico.
And did you check for @Dee87 advice on checking the resistor values?
Edit - hmmm everythings disconnected now but still pink. Let me do some research on this pink/purple screen.

Its your cmd resistor i bet eather its not connected properly or it doesnt have the correct calue anymore
Oh no... I don't see a flex, and I doubt you put a pull-down resistor across mosfets before removing the pico...
Yep, my research pointed to the same conclusion. 'CMD resistor - 4.7k 0201'
Check in resistance mode for that value but more than likely its blown so get that replaced (most likely).

Good point, @Makc16384 did you use single or double mosfet and did you have a pull down resistor on your mosfet build!? Because you could potentially replace the resistor and fix the issue but a month down the line, the pink screen could return. Can you show us a picture of what your APU looks like under the hood (metal shield) and your mosfet build.
Another point, did you kapton tape/solder mask your solder joints your pico when you finished the install. I mean all around the points of the pico that were not used because they could cause shorts with the metal shielding above and below too.

4k7 CMD resistor (but it usually happens during installation as it was in my case, check resistance, in diode mode you shoulkd have ~700 on one side=point A and ~300 on its other side) or this https://gbatemp.net/threads/no-more-old-hwfly-chip-new-rev-on-rp2040.632243/post-10161664

I checked the resistor. This resistance in one direction is 8.3k, in the other 77k. Apparently it’s really him, I’ll buy it as you said and put it. And what resistor is recommended between the G and S points of the MOSFET?
Looks clean but I do not see the presence of a resistor between gate and source. First is too replace the resistor.
3 optional options after that:
- Add a resistor to the mosfet
- Or add another mosfet so its a dual setup
- Or add another mosfet with a resistor in dual setup.
Hope that helps.

Let me do some research on the actual resistor location because those values seem way to high and you don't want to be removing the wrong component.
anywhere between 1k - 1mhz. I used 10k, others have used 3k others have used 1k. Main point is, put a pull down resistor there because if not, that leave the current floating, which can cause the mosfet to be partly on for a while. If it's a high-current load, the mosfet can be destroyed.
Check if the mosfet still works and if it does, i would add a 1k to it, if it doesn't I would go ahead and add another mosfet with a resistor on the new build.
Edit - im sure this is the 'cmd resistor' (attached)

Thanks for every one help.i found one wier cpu on pico chip is Disconnect when im soldring sp1 sp2. Now is time for nand packup.
Hello, I come to you once again. I bought a Zelda edition console, I proceeded to test it, everything worked fine, I took it apart and started to install picofly, once installed it gave me a clk/CMD error with fw2.67 (the colors of both errors are very similar, so I don't I knew how to identify which one it was exactly) I proceeded to change the wiring of both points and it was still the same, a user suggested I use the most recent fw, I did, now apparently it gives an error in RST, I changed the RST cable to verify that there was continuity in both points and still it keeps giving me an error, what seems strange to me is that clk and cmd give me strange values and I don't know why, if someone can help me please I would appreciate it
seriously I'm desperate, I already changed the wiring it originally had. I want to cry, the images are of the values in clk and cmdAttachments
First update firmware to latest version from the post you quoted and make a video of Pico booting then we'll see whats going onHello, I come to you once again.

I am using the latest firmware, in my answer is the video, here is a more complete one

ARE you still making cpu line to rp2040 pin26 and RST to pin15?Hello, I come to you once again.

Wake up! CPU to pin15 and RST on the PIN26

@SorataVP69 wrote 'a user suggested I use the most recent fw, I did, now apparently it gives an error in RST'....
You are absolutely right, I just put the cpu at 15 and the RST at 26 and everything works, forgive me for making a whole post looking like a drama queen, NOW IT WORKS, THANKS AND SORRY FOR THE INCONVENIENCE

Or, I also heard that if you use flash memory, it can act as more "RAM" at least windows tell me when I stick a flash drive into it. -
