ok, two dodgy 1708.
thanks for pointing a newb to what could be the issue RDC
main pcb one.....wont connect via bluetooth to console.
maybe will for one second, then loses instantly
Swaped with another power board, same result.
pcb two....connect to testing app, usually shows nothing until you press a few buttons then whammo....both sticks go to bottom right and wont move.
all other buttons and stick centres then respond....except stick movemenat and triggers !!!!
connects to console via sync fine.
whichever you think easier to diagnose, will use other for donor parts.
but have other donors too.
