My playstation 2 consule says to insert a format disc

To add to the solution above, note that if it's the slimline version of the PS2, rather than the fat one, you should never use a cleaning disc unless it's approved for console use; normal laser lens disc cleaners can move the laser off of its alignment and you'll have to replace the laser.

Make sure that your discs are clean; remember that the PS2 can only read Playstation 1 and Playstation 2 format discs. If you're trying to read burned games or movies, you won't be able to.

Sounds to me you got 1. a dirty drive 2. a bad laser optic

try to get a cleaning disk and run it if that does not work replace the drive that is all there is to it. There is no special buttons to push its the drive.
