Replace IC

  • On the main PCB with the power jack, replace the MXT2410 switchmode regulator IC (SO-8 Package).

  • 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.

  • 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.

Sostituisci il chip IC

Sul principale circuito stampato con il jack di alimentazione, sostituisci il regolatore della modalità di commutazione IC MXT2410 (SO-8 Package).

Attualmente il venditore "adeleparts2010" ha questo chip disponibile (potrebbe cambiare in futuro).

Il ACT4060 è pin-compatibile ma potrebbe essere una scelta problematica. Potrebbe esplodere e danneggiare i LED, quindi non usarlo.
