When you switched leads going into your phono preamp and the right channel was still dead, it indicates the problem is NOT in your turntable. It's either in your phono preamp itself or further downstream toward your speakers.
Is your phono preamp a separate component from your line-stage. If so, check the interconnects between your phono preamp and your line-stage.
Try another source like your CD player and see if the right channel is still dead. If it is, then the problem is either in your line-stage or further downstream toward your speakers. On the other hand, if both channels play just fine from your CD player, then the problem is either in your phono preamp or else the interconnects connecting your phono preamp to your line stage assuming they're separate components.
Good luck!

Thank you, John. Please see my attempt to clarify my unintentionally misleading first post in my reply to Todd's questions. It's hard for me to describe this. Sorry.
The problem is either in your turntable wiring or in your phono cartridge. You can find out where by switching cartridge leads at the cartridge pins. In other words, switch the RED lead with the WHITE lead and switch the GREEN lead with the BLUE lead. Now, if the left channel goes out instead of the right channel, the problem is in your phono cartridge, but if the right channel continues to go out, the problem is in the wiring between your cartridge and your phono preamp.
Make sure you reconnect all your other interconnects correctly before conducting this test.
Good luck!

John,
Thank you for this advice on how to test the cartridge leads! This is one area where I really didn't know how to proceed.
I'm with John! If the problem is in the turntable, when you swap pre-amp inputs the problem should switch channels so it points to the pre-amp (or further down the chain). If you swap pre-amp inputs and pre-amp outputs you will still have the left channel in the left speaker - if the problem is in the turntable it will stay in the same channel. If the problem swaps channels then it is not the turntable.
