Hello
If a disc has been put in the slot of the disc in play, Remove the disc, whose number is displayed, and press stop button.
Because of light or noise, the changer has detected a disc in the lot of the disc being played, even though it is empty. Check whether there is a disc in the displayed slot. With front panel closed, hold down "STOP " button for atl least four seconds or more.

Try CDRoller.

There problem with Lens block first you need to clean the optical with cleaning disc.After that check its work fine if not then need to replaced optical block.

The problem is with your optical unit, (TSST****), it must be firmware-updated, which version of iTunes do you have?

It seems that you may have an older sigma lens which does not have the appropriate electrical connections. Sigma can modify this for you if you contact them, and I believe the cost is reasonable. Although some lenses look very similar, there are electrical differences between earlier and newer lenses, even though they may fit on to your camera mechanically,

got same problem here

When i switch on my camcorder, it won't let me record. Error C13-02 is dispalyed on the screen. I have tried 2 different discs and have had no luck. Please help me repairs this.

I was getting the Lens Error message on my A730, even though my lens seemed to be working fine. I'd had the camera in my pocket, and apparently it tried to open but jammed. But it seemed to be OK except for the cursed Lens Error message when I'd power it on. The way I found to fix it is press and hold the "func/OK" button on the back, then turn the camera on. Now it's working again. Note that this may not work for you if your lens is actually screwed up. Mine wasn't.

Will the CD read in your computer? If so, try this freeware utility that has been recommended here in the forum. I downloaded it and actually had to use it last week on my memory stick. It WORKS! http://www.webattack.com/get/pcinspector.shtml
