Hi, the firebox flicker on my P2 Prince of Wales, worked then it didn't work, then it did somehow, but now I can't get it to work at all. If memory serves me correctly F22 on DCC mode activates it, or the second Aux lighting function in Bluetooth, but I have tried all the Aux functions with no success. I have reset the decoder with F8, and reinstalled the functions, but to no avail. Does anyone have any thoughts of what I should try? Btw all other sound functions work as does the steam generator and I can control the loco without problems.
