Unable To Read The Disc


If you have played a Nintendo Wii for any amount of time it is likely that you have seen the following error:

Unable to read disc

Is it the Disc?

The first inclination that most people have when they see the unable to read the disc error is to try to clean the disc. Sometimes cleaning the disc is all you have to do. However, it is more commonly a problem with the laser lens inside the Wii.

The Laser Lens is the Issue

When the disc doesn’t work, the next step most people take is to try to clean the laser lens. This can be very difficult on the Wii since there is no direct access to the lens. Nintendo does make a Wii Lens Cleaning Kit which you can get for about $10. There is a way to clean the lens with out the official cleaning kit and we will discuss how to do it in a later blog post. Please note, however, that fixing this issue is usually not a matter of just cleaning the lens!

The Problem is the Laser Has Stopped Working

It has been our experience that the unable to read the disc error often shows up when the laser has stopped working all together. You can do all the cleaning you want but I am sorry to say that cleaning doesn’t fix a none-working laser lens. It seems that this can be an occasional problem at first. Eventually the laser will stop working completely, and when it does you will see this error on every game disc you try to play.

How to Fix it 

The only real solution to this problem is to replace the laser assembly. We do not currently have a tutorial for how to do this but soon we will do a How To on replacing the laser assembly.

For now, here are a few things you will need. The first thing that is absolutely needed is a new laser lens. You can find Brand New Laser Lens for Wii Replacement Part online for under $15. Secondly, you need a tri wing screwdriver to open up the Wii so that you can replace the laser. Replacement is actually a pretty simple process. As was stated earlier, we will go into detail on the replacement in a future post.

The screwdriver set sold on this site is exactly what is needed to take apart the Wii and replace the lens. If you already have a small Phillips screwdriver, you don’t need to buy the set but you will need the size Y0 tri wing. Free Shipping is always included.

Hopefully this post was helpful and you are well on your way to fixing this pesky problem!
