Aasdrubale replied to the thread Nintendo Switch Lite boots to first logo then black screen after FPC connector replacement.Thank you for your response. No, this board has never had an RP2040 installed, and there are no missing components. The voltage drops all seem to be correct to me, as they have been compared with a working board.

Aasdrubale posted the thread Nintendo Switch Lite boots to first logo then black screen after FPC connector replacement in Nintendo Switch.Hi everyone, I have a Nintendo Switch Lite on my workbench. It arrived with the FPC connector that links the motherboard to the daughterboard damaged. I replaced the connector, but now the console powers on only briefly: it shows the first...

Aasdrubale replied to the thread PS5 UART commands.Hi, three beeps as soon as the power cable is connected are most likely caused by a corrupted BIOS configuration. What have you done so far to reflash the BIOS?

AE1xxxxxx = XDPE phase pwm controller error VRM 2 phases E2xxxxxx = XDPE phase pwm controller error VRM 6 phases I would check the XDPE controller and the VRMs at the both phases.

Aasdrubale replied to the thread PS5 is working normaly and then shuts down EDM-010.I wasn’t suggesting that you replace the southbridge. I was asking whether it had already been replaced, because it’s very prone to trapping flux residues underneath the BGA. If those residues aren’t properly cleaned and flushed out from under...

Aasdrubale replied to the thread PS5 is working normaly and then shuts down EDM-010.By any chance, did you replace the southbridge? Or was it replaced earlier?

Aasdrubale replied to the thread EMD-041 Flash Controller ScCmd Response Error.@thesjaakspoiler Thank you for your reply. In fact, the resistors present around the BIOS chip on the EDM010 and EDM020 revisions had already been removed starting with the EDM033 revision. In the Slim versions, they are no longer used. I...

AHello everyone, Lately, I seem to be getting nothing but nightmare boards. I received an EDM-041 board that had already been worked on by another technician. It arrived without the BIOS chip (which I rebuilt), without the retimer (which I...

Did you check UART error codes? -
Aasdrubale replied to the thread PS5 BIOS Reconstruction Without Original Dump – Is It Possible?.I haven’t performed the UART read yet. I’m currently using a known-good dump from a 1215B 61G, while my board, which is missing the BIOS chip, is a 1216A 61G. Do you think this could be the problem? That said, I’ll get a dump for a 1216A 61G...

Aasdrubale replied to the thread PS5 BIOS Reconstruction Without Original Dump – Is It Possible?.I replaced the faulty components and rebuilt the BIOS using the LAN MAC address and checksum from a donor board, but I’m still getting 3 beeps! Something isn’t right. What could be causing it?

Aasdrubale replied to the thread Missing pad in southbridge.Most of the pads on the board will normally read “LO” (open) when the southbridge is not installed. A faulty southbridge is usually diagnosed when it is soldered onto the motherboard. In any case, a failure can be identified by checking the...

Aasdrubale posted the thread PS5 BIOS Reconstruction Without Original Dump – Is It Possible? in Sony PlayStation 5.Hello, I received a PS5 that unfortunately has some missing components. The previous technician probably couldn’t identify the fault. I managed to find the issue, but unfortunately the BIOS chip has been removed. My question is: without a valid...

Aasdrubale replied to the thread Missing pad in southbridge.I can confirm that it is an NC pad on the 69GG as well. I'd also like to add that there are NC pads in the same position on all four sides. Would you be so kind as to provide us with the boardview for the EDM-010?

Aasdrubale replied to the thread PS5 UART commands.Good morning, here we go again with this cursed 80810001 error. Could someone help me out? I can’t find any obvious short circuit. The board powers on for a second, the fan starts spinning, and then everything shuts down. The power sequence...
