Hi Robert,
First of all, thank you for posting your question here at Fixya.You may try the steps below to resolve the issue.
Assuming that the disc is good.
1.Clean the lens. -Sometimes because of dust and any fine foreign objects the optical lens can'tread any disc. If you have a CD Lens cleaner, play it to the unit. If this isnot available you may manually clean the optical lens. Open the cover andgently clean the eye of the lens by smooth,clean,soft cotton buds. Be carefulwhile doing this, just a gentle stroke only.
2.Check the ribbon - Checkthe ribbon connected to the lens from the main board for scratch, damage. Once it has anopen line then of course the lens can't read the disc, this is because of themovement of the optical lens back-and-forth. Also try to erase the contact by pencileraser. If you've done the steps above and the symptoms still there then thenext step requires you a little knowledge in soldering technique and readingthe ohmmeter.
3.Check the spindle motor -Check the spindle motor that spin the disc with an ohmmeter. You can test itusing the ohmmeter (x1) even it is connected on the lens assembly.Good motor - reading should be fairly high and itwill spin. Bad motor-reading will drop to low resistance and will not spin or spin slowly.
HopeI helped you.
Have a nice day!

Hi pcheryl2,
If you have necessary tools and test instruments, know safety precaution in basic troubleshooting try the steps below to solve your problem.

Hint : 50% of my repaired unit the above parts are commonly caused of the problem.
If you confirmed that you have a defective motor then replace it with a new one. Before replacing the new motor you have to check the clearance of the disc holder with the old one. The clearance should be the same as the old because if not the lens will not read the disc if it is too far or too close.
If the above steps didn't cure the problem, high chance that your optical lens was faulty.

If you can't do the job yourself, I would advice you to look for a professional to troubleshoot the symptom.

Hope I helped you.
Have a nice day!

Hi,

Your no disc error can be a DIY like the following steps.

The clearance should be the same as the old because if not the lens will not read the disc if it is too far or too close.
Ifyou already cleaned the lens, and confirmed that the ribbon is good as well as the motor then I've advice you to send it to repair shop because the next step should be done with an expert because it is quite technical diagnosing the fault between the pick-up lens and the main board.

Hope it may help you.
Have a nice day!

If your Wii won't read any discs, even though the discs are clean, I have 2 solutions.

Visit support.nintendo.com

Or call 1-800-255-3700 for Wii assistance.

If this disc that you are trying to use is a DVD+/-RW and it has been used a few times for DVD-Video or DivX then you can try to do a FULL ERASE using the excellent ImageBurn by lightining now at v2.5.0.0 it takes about 20 mins to erase a full single sided DVD

Hope this helps.

Either the CD player does not support the format of the CD or the reading lens insidemight be covered with dust. Use a CD lens cleaner to rectify this problem.

Brain,
Is your drive supports DVD? Try to put a CD disc and see its reading or not. If this problem occurs for both CD's and DVD's discs then you might have problem in your drive lense. and if it only reads CD then your drive might not be supported for DVD's.

try to clean your drive lense using CD head cleaner, it might solve your problem, other than you have to replace your drive.

Thanks
Iqbal

your lens needs to be replaced.

If it only does this for this one game, you may have a defective game disc, it happens. Often, if you have just recently purchased it, you can return it to the store and tell them that it was defective and get a new one. If not, you can always try cleaning it though I doubt that's the problem.
nintendo.com says "If after reading the above information you are still unable to play a game disc, please call 1-800-255-3700 to discuss available options."
