The IC (chip) inside the lamp seems to die slowly resulting in flickering/flashing lamp operation when using the radio. Also the buttons may become unresponsive.

The problem occurs specifically when the device is cold and/or humid. Heating up the IC makes it work again.

  1. On the main PCB with the power-jack, replace the MTX2410 switchmode regulator IC (SO-8 Package).
    • On the main PCB with the power-jack, replace the MTX2410 switchmode regulator IC (SO-8 Package).

    • There is a pin-compatible device from Quorvo (ACT4060ASH-T) which has a different internal voltage reference but otherwise works fine. Only a resistor must be changed for this to work.

    • Feedback Voltage for MXT2410 is 1.222V, for ACT4060 is 1.293V, so voltage divider on Pin5 must be changed accordingly.

    • One can best adjust R4+R3 (series). Remove R4, measure R3 and R4, and increase. It should measure about 10.67kOhm (R3 plus R4), and it can be slightly increased to 11.51kOhm. So basically add 1kOhm to R3+R4.

Hi Thomas,

I have the same problem, but i do not understand what you are doing with the R3 and R4. If i remove R4, with what should i replace it?

Or how should i measure it?

Thanks in advance,
