PS5 cf1216b edm 033 UART CODES

[baudelaire]

Hello, I am trying to fix a defective PS5. When using it in the menu, nothing happens, but when entering a game, sometimes the image freezes and it turns off, other times it turns off and the famous blue light appears. Since I am somewhat new to this, I understood that the best option was to access the console's error codes. I am using a Raspberry Pi with the PS5-wee-tools program, which gives me the following errors:

I've also noticed that when trying a KH3 game, the textures look strange, like crystalline. I could try to take a photo with my phone so you can see what I mean.I'm new to this and I'm making progress little by little on my own, but if anyone can guide me a bit, it will surely speed up my work.
