Hi,
it's a PoE camera and it stopped working. Using thermal image I identified failing component U22 marked as 16AF which seems to be buck convertor TI https://www.alldatasheet.net/datashe...62569DBVR.html. I took it out and It is inteed shorted on the output. However, after I took it out, the resistance between the output pads (on the board) still shows 190ohm, is that bit low?
Another issue is, seems to me I must be missing one of the tiny resistors R810 that should make up the voltage devider for the buck convertor. Honestly I did this months ago, I cannot...07-14-2025, 04:30 AM -

Hello everyone
I have an MSI B550 Tomahawk Max Wi-Fi motherboard that has burned out components. See photos below.
I tested the rest of the board, and everything seems to be working properly and stable. I tested it in-game with a 1650 GPU, just in case, and in Cinebench.
I didn't install an NVME SSD on the first port but only a sata 6gb classic 2.5 inch ssd
I checked the warranty on the MSI website, and the board is still under warranty until May 2026, but unfortunately I don't have the receipt to request an RMA.
Is there anyone... -
I have a Tomohawk B550 that die suddenly. No BSOD, no weird sign or no POST/boot just a day before it happened. Fans are spinning, BIOS had flashed several times, CMOS cleared, battery removed, etc. CPUs--5600 and 3700X were tested working on 3 other boards--Aorus X570/Auros B550M-Pro-P/TUF X570, so as the PSUs--RM650x/HX650 , as well as the DRAMs, all components are tested working. The only indicator it show was DRAM LED kept lit up, no beep. The same symptom also happen on my 9 years old TUF X99 board but thats another topic, probably due to age.
Today I bring out the board to check...11-16-2024, 12:27 PM -
Hi, I've MSI MAG B550 TOMAHAWK, which stuck on CPU error (red EZ debug LED is on).
1. I've tried to flash BIOS from USB with no success (stuck on red LED blinking).
2. No component is overheating.
Does anyone have boardview of this mobo? I would like to trace the problem, but without boardview is pretty hard task. Thanks for any help.
