Use emuelect on CRT TV via AV output of S905H device

Hello, iam trying to use Emuelec 4.3 (S905H last update) on a CRT TV via AV output, but its imposible, i get the “EMUELEC” logo always in black and white netherless i config 480CVBS or 567CVBS, but then loose the image and all black screen, the system its working because i can connect via ssh! To config the output i use the 3 ways i found in wiki at the same time:
1- set res at emustation
2- set res at emuelec.conf
3- set res in the file “EE_VIDEO_MODE” on the SD in the root of the EmuELEC partition

I read all wiki and posts in that forum, can anybody help me?
thanks
