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?

If you got your money back, or if you eventually get it back, I wouldn’t condemn the seller. It is very plausible that the cartridge worked fine in his hands, both channels.
I did say several places that he has a great rep here & that he must be treating plenty of people right. But, the whole... SS knows me & Pete will do it for me was a lie. Now, he’s not responding on Audiogon & emails saying... just send it-I’ll call him & he’ll do it.  Once I found out about that being a lie... I knew-in this particular transaction-he wasn’t acting in good faith.  
If you paid with pay pal get your money back, pay pal is made for the buyer not the seller. 

It’s probably a good idea to get your money back before you insult the seller via the Internet. I’m sure he can read, too.
lewm, I think you’re misunderstanding. I never mentioned the seller previously to the last post because he has a great reputation here. I started this post even before he responded about the problem the first time.  I wanted to figure out what was wrong & if I could fix it & work with him.  I think you’ll remember from my posts that I wanted to trust & work with this person... even after so many people said something doesn’t seem right, send it back. I’ve still said he must be making many people happy bc of his rep.  But, in this particular (just mine) transaction I found out he wasnt acting in good faith.  And, I only found this out bc I decided to call SS (at people’s advice-since I really wanted to stick with him) &  check out his promised quick turnaround because he knows  Pete. Well Pete @ SS didnt know him & said so he didn’t give preferential treatment.  Noting a transaction that went bad isn’t trashing someone.  It’s simply giving out the information for other prospective purchasers to use or not use. I hope you understand now.
