lrp sxx tc issue

[Panic]

Hey guys, need your input,,,bought an LRP SXX TC speedo from a guy... Steering works fine but no throttle. LED status indicates its working - .I have Re-setup the ESC, no results. I noticed though that motor do not Beep anymore when entering setup!... Changed motor,changed sensor wire - but still no throttle, All motors work well with other ESC's and my wiring is properly connected...any ideas? is the esc useless? or i m doing something wrong?

Tnx
