The green button lights up for about 30 seconds and goes off and nothing comes on the screen

Hold down the on button for 30 seconds. Longer if you don't see the screen.

sounds like grit in the lens mechanism..... but is it worth enough to get it serviced?

it requires servicing

Main board fault. Shorted component/s on this board. Contact any service technician. This is not a user repairable fault. Gopakumar Gopalan Google

Push the power button up and hold it there for a few seconds then turn it on

Check L2 near the power switch on your DS mobo. That part usually get loosen or taken out when you drop your DS. And usually you can recover it when dismantling your DS.

More then likely your power supply failed. If you do not hear a click from the relay during the power up cycle then your power supply failed.

When you say you pressed the connect buttons on both the keyboard and mouse, do you mean you pressed the connect button on the receiver, and then you pressed the connect buttons on the mouse and keyboard? If not, then that's what you have to do. The 30 seconds of blinking on the receiver is normal, as it gives you time to find and press the buttons on the mouse and keyboard.

I hope this helps, and good luck!

there is no power and it will not charge
