Red hat 5.6 on Parallels virtual machine boots but goes to blank screen

Title says it all.  I installed Red Hat Enterprise Linux 5.6 Server on a virtual machine.  My desktop is running 64-bit Windows 7.  I encrypted the Linux disk.  It boots and I can get to the GNU Grub menu.  

But if I boot I just get a dark screen.  What do I need to do?

How do you encrypted it?
Before you encrypted it, could it boot up normally?

If yes, then could you un-encrypt the disk?

It asked if I wanted the hard drive encrypted during the installation process.  So whatever encrypting took place, Red Hat did it.

Did you type in the passphrase to access the encrypted disk at boot up?

I'm never prompted for it.  It goes through a boot sequence and then goes blank. I just tried to just type the passphrase and nothing happened.

It is kind of hard to troubleshoot the issue for blank screen.
It has something to do with Grub setting.

Check the memory size in vm virtual video card's setting.

I've requested that this question be deleted for the following reason:

None of the solutions resolved the issue and we now have an installation I can VNC to, so I am no longer working on this.
