Generally, I find I need to turn up the volume a bit more for TT than for digital sources for similar vol level. From your post, though, it sounds like you have a very significant difference.
Anyways, which phono pre-amp & cartridge are you using? It would be helpful for diagnostic suggestions.
You may want to double check that the pre-amp's gain is set for type of cartridge you are using, as Bob suggested. Depending on how the gain switch is set up (assuming your preamp has one), might have accidently switched the setting. If you are using a MM cartridge and your preamp has different gain settings, have you tried a higher gain?
If a tube pre-amp, perhaps tubes are at end of life?
Is Dolby Volume disabled in your TT input set-up?
Not sure if this may be a work around, but maybe try turning Dolby Volume on and increasing the Dolby Vol level?
