Hi everyone,
I’m repairing a Sonos Arc power supply board and could use help identifying one damaged SMD component.
So far I have:
-
Replaced the main IC (marked 1342BHDGD)
-
Replaced the resistor in the yellow box – that one was readable at 24.9 Ω and had a burn mark.
However, the component marked in red is physically cracked and has no visible markings.
-
In-circuit it measured around 2.09 kΩ,
-
Out of circuit it measures open (OL), so it’s definitely failed.
I’ve attached:
-
A close-up photo with the damaged part highlighted in red
-
A wider photo showing its exact location on the board
If anyone has:
-
A schematic
-
A known good board to measure
-
Or experience repairing this Arc PSU
I’d really appreciate knowing:
• The correct value and type (resistor? bead?)
• Package size
• Any recommended replacement part numbers
Thanks in advance for any help!
