I'm working on an SCPH-1000 (PU-7 motherboard) that's developed a strange audio issue, and I'm hoping someone here has seen this before.

• No left channel audio from the AV Multi Out.
• If I connect the left and right RCA outputs together, the left channel disappears completely, leaving audio only on the right channel.

What I've already tried so far.

• Replaced all electrolytic capacitors around the AKM DAC.
• Swapped the AKM DAC with a known-good one from another working SCPH-1002( though its a different version AKM4309VM, after changing it still plays audio same issue as before).
• Removed the left-channel muting transistor to rule out a faulty mute circuit.
• Checked continuity from the AV Multi Out pins, and the traces appear to be intact.

While probing pins 15 and 16 of the AKM DAC, I accidentally caused the left channel to start playing while the CD was spinning. The audio was present but slightly distorted. That initially made me suspect the DAC itself, but replacing it made no difference.

At this point, I'm not sure whether I'm dealing with:

• a broken trace or via,
• a fault in the analog output stage,
• an issue elsewhere on the audio path,
• or something I'm completely overlooking.

Unfortunately, I don't have a proper schematic for the PU-7 board, so I'm troubleshooting somewhat blindly.

Has anyone experienced a similar fault or have any suggestions on what I should check next? Any advice, measurements, or likely failure points would be greatly appreciated.

Thanks in advance!

Hello! I found a dirty, roach infested, rust infested, ps4 model CUH-1215A underneath a trash heap. It boots up, works fine, and I started to clean it up. The only problem is these dark spots or burn spots on the ground of the motherboard.

I did research and talked to A.I. saying this could be a burn spot and I need to chip away at the surface and put epoxy? to make the surface even with the rest of the MoBo?

Scraping the MoBo seems unsafe, unsure what I should do here. Any suggestions? preferably from somebody very experienced.

I attached images to show what the spots look like.

The original cable has this printed on it:

SUMITOMO-G [RU] AWM 2896 80C VW-1 -F-

I cannot find a ribbon cable that is the exact same. Can I instead buy ++this one for example++.

I've already verified the heatsink clamp (Step 19) and the main power supply screws are in place. Does anyone know if there are specific 'hidden' spots for these two screws, or if some models (like the CUH-20xx vs CUH-21xx) have extra holes that should remain empty?

I’m having a problem with my PS5 (original model with disc drive), and I’m hoping someone can help.

The console works fine on the home screen, but when I play certain PS5 games like Spider-Man 2 or sometimes Fortnite, it suddenly shuts off completely after about 5–10 minutes. The screen instantly goes black, the PS5 loses all power (no lights at all), and I can’t turn it back on unless I unplug the power cable and plug it back in.

I already cleaned the fan and removed the dust I could reach, but the problem is still there. The console isn’t in a closed space and has plenty of airflow around it.

Has anyone experienced something similar? Do you think this sounds like a power supply issue, overheating, or something else?

Any advice would be greatly appreciated. Thanks!

I had/have a problem with my old PS2 SCPH-30003 daughterboard. This small board holds a CR2032 battery and the clock chip I believe. I noticed that after a few months, the new CR2032 battery I had put in was totally flat.

So, I tested the board and found out that there was a 100μA current draw with the board completely isolated and disconnected. Supposedly this isn't right.

On my original board, I did notice some kind of corrosion around the negative battery holder terminal, as well as the pins of the clock chip. I didn't see anything like this on the replacement board.

But after testing said replacement board I bought (listed as working), the exact same thing is happening...

The weird thing is, that the original Sony battery from both boards had NOT drained. Both were sitting at around 3.08v.

Does anyone know what might be going on here?

Thanks in advance!

However, the rear case is still firmly stuck near the L1 and R1 triggers. I've read about the hidden clips in newer revisions and tried prying the rear shell outwards while pulling up, but they won't budge. I'm afraid of applying too much force and cracking the shell or breaking the motherboard.

Does anyone have a specific trick or a different angle for a spudger to pop these specific 'hidden' clips near the shoulder buttons without damaging the plastic?
