Bad logic board?

Hello guys, I have here a problem with my Macbook. It does work well on external but no internal image. Well I know the lcd and all the cables are good so I suppose it is a logicboard problem. is there anything I can try before getting a new one ? I have tried every reset that is through the web (SMC,PRAM...), so if you had any last resource idea would be awesome :)

Is this a good question?

Francisco - If you are able to use an external monitor without any problems then you have proven the issue IS the internal display sub-system and/or the cabling to it.

Why do you think it's not the internal display?

What do you see when you shine a flash light through the Apple logo on the display (poor mans back light) do you see any image at all? If you do it's the backlight circuit which needs repair. Can you tell us what happened before you had the display go out on you. Did you drop or bang the system, dented any where? Or did you get the system wet?

No man, no image at all. I did not wet And I looked at the board just in case but it seems fine. I think it must be the conector on the board :(

One more thing, I do not know if ith Helps anyway but if I try to access the iSight using an external monitor it tells me that there is no camera. And on pref pane it does not detect internal monitor so I really guess it is the conector, I can not see any other option but I am no pro. I really thank you for your help. If you have any other idea of what I can try it would be great

And one more thing.... I tried another display And the camera actually works so the problem is only The display. I am really thinking it is the conector.. Is there any way to relaxe it ?
