Speaking of idiots ripping caps off the board, is there a semi-effective way to repair a lead port that has been partialy or completly damaged/ pulled out? I know I've burned a couple rings before and the board still works, but they kinda scare me.

Hello all,
I have a Numark MixDeck from 2011. The power supply seems OK but the DC port within the deck itself seems broken or loose.
The device will not power on until the DC connector is inserted and then turned a little counterclockwise then it works but if you touch the cord, poof!
I am guessing the cube shaped DC port on the board is bad and needs to be replace?
Does anyone know what this part is called so I can check on DigiKey or somewhere?
TIA... -
I have a thinkpad L480 NM-B461 rev 1.0 laptop functioning normally with Type 1 port (JUSBC1)
if you use port type C 2 (JDOCK1) with a usb type meter it only displays 5v, thank you
I tried to look at the schematic diagram USBC_VBUS20, which is the port path from JusBC 1 to U4701 then goes to the system2 charging IC, why is there no system2 path leading to the charging IC on the TYPEC_VBUS20 port which is JDOCK1, thank you for your help.
if you look at the power sequence there must be 2 types of port type C a (JUSBC1) via U4701 and port type C b (JDOCK1)
On the type... -
Hi all,
I sent my ProArt Studiobook 16 OLED (H7600, 12th Gen Intel) to the local repair guys to have a very simple DC in port replaced. I sourced the part myself on accessoires-asus (french company) after struggling to find the right part in the UK. It looked completely the same to the installed part from what I can tell. Originally the only issue with the laptop was a bad / loose DC connection, and so the computer and battery acted completely normal aside from a very poor connection that would fail at certain angles. After the repair was completed I brought it home and used it for... -
Hi everyone,
I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.
🛠 Original Issue
The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.
I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

I have a Dell Latitude 7410 with an Intel i7 10th Gen CPU. The USB Type-C port is not working, and since it's the only charging port on the device, I'm unable to charge the laptop.
I inspected the motherboard and found that the IC labeled TPS65988 had a short circuit. I ordered a replacement IC from Alibaba and replaced it. The short issue is now resolved, but the laptop still doesn't charge, and the Type-C port remains non-functional.
After doing some research, I found out that the TPS65988 needs to be programmed after replacement in order to function properly.
