You might find you need to re-tune the L.O. (Local Oscillator) frequency in the lnb, such that actual known frequencies match on screen display frequencies. If you're feeling confident with taking things apart you can do the following:
1) Prise apart LNB
2) You should be able to distinguish two separate circuits, one for low band [10.7 to 11.7], one for high [11.7 to 12.75]
3) Each will contain a variable capacitor which can adjust the LO.
4) Tune to a low band channel on a known frequency, view on screen, adjust one of the screws - very slowly, if channel goes off screen you've found the low band adjusting screw, if not, try the other screw.
5) Once you've identified high/low band screws: tune to low band channel on know frequency, adjust the screw slightly till channel dispears off screen. Re-tune receiver - you will find the on-screen frequency is again different from what you started off with - if its closer to the known frequency you're going the right way with the screw, if not, you're going the wrong way. Use small itterations until you bring the known frequency close to on screen frequency.
6) Repeat the procedure in 5) for high band.
7) You've successfully tuned your lnb LOs.
I bought an lnb off eBay that had drifted off in this way, and wasn't able to tune to channels in higher frequency range (above 12.7GHz), so I re-tuned the high band lnb so I could get the channels I wanted (In this case: 12732.00 MHz, France 3, Analogue, Atlantic Bird 3 [5.0°W]). A picture of the said tuning screws would be nice, but I'm affraid my LNB is on a dish on the side of my house!
Of course, you could try a different LNB.

Happy tuning.
