PS5 No Beep, but has power

[james-london]

Hi All,

Hope you are all well. I have read through the forum trying to find some help, and thought I would post to see if any of you can point me in the right direction. I have a PS5 Digital which is not powering up. Pressing the power button gives me nothing - no beep (no even after multiple presses).

Checking with my multimeter, have all voltages where they should be - PSU is good, I have 5v, I have 3.3v - i have checked in diode mode for shorts, and even with a thermal camera and cannot find any faults EXCEPT when I press the power button i do NOT get the 1v "switch on" line on the circuit to the left hand side of the motherboard near the Dialog IC (there are no shorts near the Dialog IC).

Has anyone experienced this before? Any help would be very much appreciated....

Thanks in advance...

Check if that ic got what it requires to work.
No beeps normally tends to southbridge or standby line short

I'm curious about this as well. I've seen this flashing process done before on some random repair videos. But I'm curious where they even obtain that dump in the first place. Are they the same on all systems so you can just pull it from one, and have a working copy for future?

I’ve got most dumps on my PC. I need to add them to my one drive.
I’ve done a couple now, easy job and good money to be made on the repair.

I thought that would change serial number since BIOS contain unique info

Hello, I have no beep and no light since I damaged the ribbon between motherboard and light board. Now the connector leading to the light board has 2.46V but the connector leading to the power switch is 0V same as yours. I'm wondering if BIOS is corrupted and do you mind sharing how you fixed BIOS corrupt?
