ang gulo ng post mo dun ka dapat sumagot sa una mong post.......

ang tanung bakit mababa ang red mo? dapat pariho ang RGB voltage mo. check nyo po ang resistor at transistor drive nyan.

sukatin mo kung may 1.2VDC ang RGB in sa C-board mo bago pumuntang RGB amplifiers.. resolder ka sa C-board papuntang RGB out ng jungle mo.. baka naman 5 blinks yan?
