TOC ERRORa When I press play I get "TOC ERRORa" and then the unit shuts down. It seems to be the disk as I get the same error on a second unit, but what I don't understand is what happened to the disk. This happened right after I had played (successfully) the entire disk. Didn't remove it from the unit or anything. The error just started cropping up. I really need this file too.

see this cause and remedies:

Does not play disc

1. No disc. - Load a disc into the tray.
2. Disc has been loaded upside down. Place the disc with the label side up.
3. Disc region code does not match region code of the player.
4. Disc type is not the correct type to play.
5. Disc is damaged or dirty. Clean the disc or try another.
6. Moisture may be condensed inside the unit. Remove the disc and the leave the power on for one or two hours.

Finally the OPU optical pickup unit contain lasser beam, NOT are reading the TOC from Disk, YOU Must go to the repair shop Tv FOR fix it.see the diagram
God bless you

TOC disk error normaly occurs when tool 1 of the set that goes in the small square hole at the front left of the drive bay above the power switch is missing or installed wrong

That's an ancient player!

Try using a different disc. Try using the external power supply.

Table of Contents errors usually happen if you lose power before the disc is 'finalized' when recording. You cannot unplug the unit before it is done with a disc, or remove it until it is done finalizing. You will see "TOC" flash when you are done recording. When it stops, then you are all set. Try a fresh disc and see if that works.

Hi,

According to you You don't have use your disk play for a huge time, so that it may damaged or lens became dirty.

You can clear the lens with lens cleaner (clear the optical head).

check the battery was properly charged or working.

Check the disk moved properly.

To prevent the disk erase or damage slide the accidental erase prevention tab.

You can show it to the Technician.

Without a decent Table Of Contents, your MiniDisc will NOT work, as you've found out. Does it matter what brand of MD you use? I would record it at "1X" and NOT 4x speed too. Try erasing a blank minidisc first and then shut off the unit and then turn it back on and see if the TOC works. Try adding a title, then turn it off and back on. Then try the CD to MD.

Sounds like you lost power when you were finishing recording a disc. On a home unit it got unplugged before you had the TOC written, or on a battery unit the battery died when it was writing the TOC (table of contents) for the disk.

The TOC error is the same error seen on computer disks, TOC is the table of content, this has to be read before the the unit will know the details of tracks etc......

If every disk inserted (not just burned discs) has this error, the laser is faulty or out of alignment. Thanks for using FixYa - a FixYa rating is appreciated for answering your FREE question.

Hi,

I am sorry to say but your unit needs to be sent for repair. The TOC error shows up when the unit can't read the Table Of Contents of the disc (and simply shuts down after trying)....and in your case, you said it can't read any disc. This indicates that the lens unit has malfunctioned and needs to be repaired or replaced.

Unit displays TOC error when I inserted two new cds I purchased.
