First of all I would just like to say that, this is a great idea for a forum! A console repair forum where people can share there knowledge and experience! There are know real console repair guides, most of what we learn comes from are own experience.
I really enjoy repairing consoles, mostly Nintendo systems. So if anyone needs any help, I will be very happy to assist you

I have learned how to repair many faults with the Nintendo DS & DS lite, but I have recently stumbled across one fault imperticular which is giving real problems.
I have 3 DS lite systems with the same fault.
DS powers on - green light stays on - both screens are blank

Replacing the mainboard would fix this, but where is the fun in that?

So if anyone has any idea how to fix this, please tell!!!
