ps5 with uart error: C0810303, replaced MN864739 was shorted, the ps5 starts up shows the image when restoring the database it turns off, uart error still C0810303, I replace another chip but nothing, I notice that I am missing the 1.8v at this point I attach an image, what generates that voltage? and what are the other voltages that I need to get in that area? thanks
nothing I can’t find the culprit, I would like to try replacing the cxd90069g, what do you think?
The 1.8V are generated by the little five legged dcdc bug converter. The lower pin on the left is the enable, which should read 3.3V if powered on and enable the 1.8V.
Thanks dear for your always answers, actually checking a twin card 1.8v they are enabled only with the console on, in this case as I anticipated in the last message I solved it by replacing the south bridge, having not found anything strange on the main. I don’t know how to explain it, does it have some logic? because I honestly went at random, thinking that the cxd was not communicating correctly, does what I say make sense?
