No right channel in new cartridge


I just got a Sumiko Blackbird & mounted it.  I have no right channel. I haven’t fine tuned the mounting but, That shouldn’t make me lose a whole channel.  Once or twice I’ve heard a hum in the right channel before I put the needle down. When it goes down it stops & goes silent.  The channel isn’t effected in CD, DVD or radio.

i bought it here(all positives on the seller) & it only had 10 hours on it. It didn’t come in the original box but came screwed into a box... seemed pretty secure.  I checked & reconnected all the pins, jacks into the AVR & ground wire.

What should I try next?

Lewn, do I switch straight across? 
White with Red
Blue with Green

Even if the cartridge is returned, this is an education.  

But, I would rather be playing my music.
Dear @tochsii: Other that what lewm posted: do you still have the cartridge you were using before this Sumiko?, if yes then mount it again and test if everything is fine .

Regards and enjoy the MUSIC NOT DISTORTIONS,

Only 10 hours and the seller didn’t have the original box? Sounds like BS to me!
Buying a used cartridge is a big mistake 10 hours could be 1000hours.Try getting your money back good luck with that one though.Your in a world of hurt NEVER buy a used cartridge. You got ripped off big time.Good luck though!!
