Hardware errors can be fixed only at workshops. You may try opening and checking on your own using the "V8--take it apart" guide, but I recommend taking your phone to a repair personnel or the service center if you have warranty left....
Most probably there is some friction due to corrosion or faulty hinge angle. Get it checked asap or it may create further problems!

Thanks to Krawls80 for a gr8 sig.!! HIT 'THANKS' BUTTON BELOW IF I'VE HELPED!!
Thanks! It is still under warranty. But I'm afraid that when the repair shop works on it they may damage it or send me a re-man. Does anyone know what luck they have had with motorola warranty repair? Just wondering because the phone is MINT and I'm making a collection.
