Hi,

1. Turn off the camera.
2. Remove the lens, battery, and CF card.
3. Allow the camera to sit without power for approximately 20 minutes.
4. Insert a fully charged battery, and turn on the camera.
5. Depress the shutter button as you would to take a picture.
Does the “ERR 99′ message appear? If it does, then the camera should be
serviced. If it does not, then please proceed to the next set of steps:
1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.
5. Depress the shutter button as you would to take a picture.
Does the “ERR 99′ message appear? If so, then the CF card is the most
likely source of the issue. Try using a different card.
If the message does not appear, please complete the following steps:
1. Turn off the camera.
2. Clean the lens contacts by gently rubbing them with a pencil eraser
or soft cloth. Be careful that you do not let any debris fall into the
camera body.
3. Reattach your lens.
4. Turn on the camera.
5. Depress the shutter button as you would to take a picture.
If the “ERR 99′ message only appears when one particular lens is
attached, then that lens should be examined by a service technician.
If you see the “ERR 99′ with a different Canon lens attached, then the
camera should be serviced.

The ERR message is not a good thing. Read page 132 of the D80 Manual. Also, try a factory reset found on page 129 of the manual. On the left side of the camera is the terminal cover, inside below the USB connector is the reset switch. If that does not work call Nikon digital 1-800-645-6689.

Error 4 means" too much inlet water", turn inlet water tap down.

Is there a memory card in the camera?

Also try cleaning the contacts on the lens (light rub with a pencil eraser works).

I can help you with you Coby 610 mp3 player.

Replacing the firmware in your mp3 player will correct your 'file sys err' message and have it working like new again.

Oh, i had this problem several times... look, the best answer that i can give you is to buy a new one, there's sony's cd-players that are great, me and my father have. now, if you want to stay with this cd player just insert the cd several times until it will play. but again, you better buy a different one.

Since the cds are stuck inside, you need to open the unit and remove them. There are four screws on the top cover. Remove them (2 on each side) and lift the cover. You should see the cds, remove them, then plug on the unit.
