I've been reading up on the LG LST, I got the same device.
Two options that you may want to try (and there may be a third).
1st) Make sure nothing has happened to your DVI cable, make sure it is tight on both ends. Undo it and blow on the connectors and resecure it if need be. HDCP involves communication between the HDCP chip on your LST and the HDCP chip in you display. If you cable is loose, dog chewed or too long then it may be interfering with your HDCP handshake.
2nd) You should be able to go to RGB display option and dispay in HD over the same DVI cable. This was discussed much in the forums I have been reading about.
I hope one of the above options helps you. In fact I hope the vacume or kids knocked the cable slightly loose and you are back in business after tightening it.
The 3rd option would be to do a google search for LST-3510a and HDCP, you will find all kinds of solutions, work arounds and firmware update discussions.
