Hello,
I have a CFI-1215A PS5 (EDM-030 board) here that won't boot normally. It currently will immediately boot into Safe Mode upon power button press with a screen that says "Processing" and then a progress bar that usually begins around 75-84% and slowly climbs up to 99% where it will hang forever. The console will not ever escape past the 99% mark.
Things I have tried:
1. Tried force booting into Safe Mode by pressing and holding power button for 2 beeps so I could use a reinstallation USB, but the console still boots into Safe Mode with the...

PS5 | CFI-1215A | EDM-030 | Stuck In Safe Mode 99% Processing

Wow. I just connected power through a USB-C meter to take some measurements and I saw a puff of smoke. Looked and see DT8 is now charred. Part CESD2510UC3V3U. Seems to be ESD protection. Coincidentally, this sounds very similar to another post I was following where you helped someone else with a similar problem, mon2. That post can be found[URL="https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/3247989-help-please-lenovo-ideapad-5-14itl05-power-and-charging-problem/page2"] here[/URL].Wow.

Sorry for the late reply. I became busy with other repairs.
No, this model does not have a coax/barrel charger. It uses USB Type C only.
EDIT: My mistake. There is a coax/barrel connector on the board it just didn't come with one installed and the hole in the side of the bottom panel isn't there to allow for a charger of this type to be connected. I would have to connect a DC-Jack and then drill the hole in the bottom panel if it worked.......Last edited by grimacelord; 03-13-2025, 07:11 AM.Leave a comment:

I may have measured wrong because I I was misunderstanding what you wanted me to measure. Resistance mode, one probe on pin 19, the other probe on pin 20, I am measuring 21 ohms. One probe on pin 19 and other probe on PRB19 is 10 ohms and same with the other. Hope that clarifies. Sorry for the confusion...Leave a comment:

I'm getting 10.6 ohms on both....Leave a comment:

Forgive me, but I am a bit confused on the instructions. I have found charger IC @ PUB1. Are you wanting me to measure the resistance between pin #19 and PRB19 and then pin #20 with PRB18?...Leave a comment:

Any ideas, mon2? I'm stumped.Leave a comment:

Hopefully the quality is sufficient. Thanks, mon2!...

Lenovo IdeaPad 5 ITL05 | LA-K321P | Liquid Damage & No Charging
Hello,
I have an LA-K321P board here that came to me for no power. Upon visual inspection of the board, I found some liquid damage around PQB13 area. Replaced PQB1, PQB2, and PQB13. Laptop will power on if the battery has a charge, but the computer will not charge the battery. USB Type C meter shows 20V being negotiated, but virtually zero amp draw (0.0100 at most that appears for a brief second about once every 5 seconds or so). Looking through thermal camera, UT1 (SN2001024YBGR) is getting hot. I have schematic, but no board view. Was hoping someone could help me get this charging... -
Thank you for the reply. Just for clarification, "...and by the red caps", do you mean the component in my picture I posted in the original post?...Leave a comment:

Upon further probing, I have found a short on Pin 1 of C9F1 which is V_VTTB. I am reading 0.013V in diode mode and a working Xbox has a diode reading of 0.305V.
The only components on that entire V_VTTB line is a whole bunch of resistors and a few capacitors. I removed ALL of the capacitors on that line and it's still shorted to ground. What does that mean? Internal short?Leave a comment:

Hoping somebody can see what I am working with here because I am really not sure what I need to check for.Leave a comment:

No Power - Only Beeps - Missing 5V Rail Near F7502
Hello,
Working on a PS5 that came to me for no power. Console would not beep or power on when pressing the power button initially. Board model is EDM-010.
I began by taking the console apart and performing a visual inspection on the board. Everything looked fine. I then tested the various fuses across both sides of the board and found that F7001 and F003 were both blown. I then looked closer at F7001 and found that the right side of the fuse read short on my multi-meter, so I injected 1V and found that a capacitor near the F7502 was getting hot, so I removed it and the... -
Attached two screenshots from the relevant schematic page....

Well, I decided to test my own theory and use a brand new power supply in case something was weird with the original and even using a new power supply, Q9F1 blew as soon as I connected it to power, so it's not the power supply causing it. Still not sure what to check...Leave a comment:

Xbox One S - 12V Rail Short - Q9F1 Keeps Blowing
Hello,
Have an Xbox One S here that has a short on the 12V power rail. There is no power, beep, or partial fan spin when connecting power cable.
After diagnosing with thermal camera, Q9F1 MOSFET (NTTFS4C50N) is getting hot. When I remove this MOSFET, the short on the 12V rail disappears.
I first replaced Q9F1 with one from a donor board and then partially reassembled the Xbox to test. When I plugged the power cord in, I got a partial fan spin and I thought I had fixed it, but unfortunately, the Xbox still did not power on. So I then disassembled the Xbox... -

Hello,
Computer Model: Dell Vostro 5620
Service Tag: 4HPNGS3
Reg Model: P117F
Problem: Computer appears to try to power on, but doesn't complete POST and doesn't charge normally. This machine might have several problems, but I wanted to start with a new BIOS.
I created a dump of the original BIOS which is on a GigaDevice 25B256EYIG WSON8 IC and then I downloaded the latest update from Dell and used Dell PFS python script to extract out all of the images but this is where I am not sure what to do. I know I need to merge in the BIOS update image...Leave a comment:
