well, the error messages are a bit too "serious". not all is broken.

i investigated and your tuner has is not configured for properly.

i am working on a proper fix for it at the moment, but in the meantime, you could try:

1. edit cxm_tuner.c, find "TCL 2002N-6A"
2. change "CXM_TUNER_TV_SYSTEM_MN, cxm_none_system_code_style" into:
                 "CXM_TUNER_TV_SYSTEM_MN | CXM_TUNER_TV_SYSTEM_BG | CXM_TUNER_TV_SYSTEM_DK,  cxm_none_system_code_style"
3. recompile, reinstall and retry.
4. let me know.
