Need DIC Help
Okay so the past week my DIC has been completely blank. It was working fine, then last Tuesday when I turned the car on, I didn't get the usual Corvette By Chevrolet, and when I press the buttons nothing happens on screen. I figured my battery was just a little low because I haven't driven it in a few weeks and when I did it was just a quick run to the grocery store. I charged the battery all the way up, and then went for about a 40 minute drive to try to see if that would do anything. It didn't, and I'm not sure what's wrong....... Any help is greatly appreciated.

Sorry, but I think your DIC is DEAD. Looks like you may have to pull it and send it out to have it tested/repaired. The only other option is to find someone who can pull your codes with a Tech II and see if it might be a communication issue with the Serial Bus. I will see if my service manual has any other suggestions but I have helped with a number if IPC issues and I think it may be the IPC itself. Not at home now but will look at the FSM when I get home.
Oh, do you have HUD and if so does it display correctly?????

YOUR DIC IS DEAD.... 
Thats what she said! 
On a more serious note, it may do you good to remove the IPC and take it down to its basic components. Its a fairly simple process.
Look for cold solder joints and other circuit board issues on the main board.
If you dont feel comfortable doing the work your self, take it to a TV repair store.
Here are a few post to help you out:

Most BOARD issues can easily be fixed. The DIC Display is a florescent display that is connected to the circuit board. If one of those connections is intermittent, It should normally be easily fixed.
IF,, something inside the IPC is bad, NO ONE from GM offered a replacement part. If your lucky and its a well known electrical component with a part number that can be cross referenced, and soldered back on the board.
Most of the microprocessors are not going to be found commercially.

If you don't have experience in soldering and electronic repair you could do more harm than good. If not, you should remove and send it to an experienced Delphi repair facility.
If you need some recommendations let me know. I have no personal experience with an IPC shop but I know of 4 or 5 that apparently have C5 IPC experience. One is close to you in Utah.
PS: You asked earlier if a dead battery did this. My answer is NO.

My links are on my desktop at home. Will post all 5 for you. Hopefully someone else here who has had good experience with one of these guys or others will chime in. The other option is to get another IPC from one of the Forum vendors and if they can't reset the odometer your dealer or someone else can do it for you.

I was thinking if I find exactly what board is messed up, I could get one off of a different Vette and just swap them....

The MAIN board is what has the issue.
The main board contains the MILEAGE INFO and the DIC Message display. If your issues is intermittant,, it SHOULD be a very simple process to repair.
Post contains a detailed picture of the main board. It also shows the display and how it mounts to the board.

Purchase or borrow a strong magnifying glass and examine EACH one of the soldered pins for the display. The solder joint should be smooth and continuous and shouldn't have any cracks.
Some of the solder joints on the EBTCM board are horrible. I cant believe that they passed inspection.
One of the solder joints on your board or something where the vacuum florescent tube connects is poor.
