Neo 2.2 Mod Installation - Boot up but CD Tray will not Open ... ?!?

[cLeAnEr-23]

Best of All: i set the Console to orginal State (removed ModChip).
(v4 Console.PAL)

Same Problem; PS2 Boot's normal, BUT not Eject the DiscTray when
pushing the Eject Button. Also not if pressed Down for a couple of seconds..
But i can see that the red laser Point is searching for CD or anywhat,
it's alive (for now..)...

Whats the f***ing problem? Any Suggestions ? Thanks!!
