Won't Eject or play DVD...just reads E 27 00

The problem is likely to be a jammed disk. All you need to to do is remove the cover by removing the 7 screws locking it on. The jammed disk will most likely be located where the dvd is read, this can be tricky to remove so carefully remove a screw at a time from the disk positioner (device with white disk on it, not 5 disk tray) gently trying to remove the disk after each screw is removed. The fewer screws removed the better. Usually only the screw on the right side needs to be removed to give rome to remove the disk.
