Purple screen switch oled after switching chip

[Fede12]

So after installing a new chip and checking all the values in diode mode on first boot the purple screen appeared, purple screen is here also after removing all cables

Before turning on in both occasion i checked the connection in diode mode and they were all good, the sp1 point is not a pr

oblem since i have been running the switch without it for more than 1 months

hi,

missing capacitor. This can't be good for the CPU.
(EDIT : but I don't know if this can give a purple screen BTW)

The cmd resistor is most likely the cause of the people screen. It's 4.7k ohm 0201. The missing sp1 cap is just a filter from what I've seen and should still be ok without it.

Hi, thanks all for the attention
My problem is not that resistor as it has a good ohm value

Your problem is most likely that one, it’s a really common problem, do you measure it directly on the board or desoldered?

Read the first thread in my link above, the person thought it was ok like you do.
A new one and the purple went away.
