Neo 2.5 DVD Eject Button/Tray Problem

[Nincat9]

Hi I have just installed a Neo 2.5 DVD on my v4 US PS2 ....I can't seem to open the tray with the eject button. There is no light on the eject button either. When I press the eject button the reset button turns green. I tested to see if holding the reset button will cycle through all the flashing and different modes and it does ...but only for the reset button .....the eject button won't even light up.
I tried look up this problem on the forum but there were no solutions.
Does anyone know what my problem is and how to fix it?
I even tried resoldering all the wires...and even tested the silver cable with another similar cable....the results are the same ...can't eject...and nothing on the screen also...

Please help..
