PS5 pro 1 beep and no boot

[joliver82]

Hi guys,

I have a PS5 pro board model VSM-010 which doesn't boot, when trying to start the console, it beeps once and the blue light is shown for one or two seconds and shuts down.

I've been checking it, the UART showed the following errors:

• 00 27/09/2025 1:25:53 80810001 Severe PowerSequence - Power Sequence Error - General Power Failure (Peripheral, GDDR6, APU, Data Line Short)
  |-(OK 00000000 80810001 FFFFFFFF FFFF0023 10000100 206E 0024 FFFF FFFF:2E)
  Click for TSB Information
• 01 27/09/2025 1:25:53 C0810303 Low HDMI IC Problem or Data Line Short or Power Failure
  |-(OK 00000000 C0810303 FFFFFFFF FFFF0023 10000100 206E 0024 FFFF FFFF:3E)
  Click for TSB Information

So I started checking the HDMI section of the board. I found that I had the HDMI encoder MN864739 and a TPS7A7401DSDR regulator shorted. I've removed the components although not replaced them because I've not bought the new ICs still and I don't have other board. Having done this, the detected short disapeared

After having finished, I made a visual inspection of the whole board just in case and realized a burnt regulator. The IC is tagged as V0=BE. I attach a picture:



The fuse shown in the picture es F7005.

Usually these kind of tagging is from richtek, I've searched for richtek v0= and only found RT9271GB ( https://www.alldatasheet.es/datashee.../RT9271GB.html ) which is not the same IC in the board.

Does anyone know which IC is this one? I need to search for a replacement for it

Thanks in advance

For anyone interested, finally I think I've found the model, Richtek 6575K --> https://www.richtek.com/assets/produ...DS6575K-00.pdf

Sadly it looks like it cannot be bought. I've not found it in any online shop :/
