i have cable and am currently directely connect by coax cable from cable box t back of olevia 232-s12. i've gone thru all settings that come up- channel serch ect. and can't get a picture or sound.I just acquired this tv from an friend of a friend so to speak?. i have no manuel. is there somthing i'm doing or not doing that i cant get a picture. when i first viewed it there was a picture. this person told me i had to have it in the composit mode to get a picture and he had a vcr/dvd connected with simple phono plugs. Is the tuner gone bad??? or is there some type of setting i am missing. or am i just not hooking it up correctely. i want so bad for it to be the latter. i must confess, i didnt pay much attention to him cause i just knew he didnt know what he was doing. ooops i gess i dont know as much as i thought. HELLLP. THANKS
