-	[title] Replace IC
+	[title] Replace the IC chip
	[* black] On the main PCB with the power jack, replace the MXT2410 switchmode regulator IC (SO-8 Package).
-	[* black] Currently a seller "adeleparts2010" has this chip available (might change in future). ~~The previously recommended pin-compatible device from Quorvo (ACT4060ASH-T) is not a good choice and might cause more damage.~~
-	[* icon_caution] ~~Warning: I just encountered~~ a ~~problem with the ACT4060~~. It ~~blew~~ up ~~on one lamp~~ and ~~damaged the~~ LEDs ~~as well.~~ So it ~~seems not a perfect replacement after all~~.

+	[* icon_caution] The ACT4060 is pin-compatible but can be a problematic choice. It can blow up and damage LEDs, so don't use it.
