Hi! I'm new on this forum and my english is very limited but we'll try.

I have no backlight on the LCD of my macbook pro 15'' 2,2 GHz (2007) and the iSight do not work to (green light on but no picture.
The screen is OK. I can see my desktop with a strong flashlight on or with the sun on the LCD.
I changed the inverter but do not work more.
I've tested the connexions : the inverter recieve 5 V on 1 cable, 2,1 V on an other and nothing on the 3 other cables.
I dont know if it's good.

I hope someone will have ideas to help me... ;)

if the iSight and backlight don't work, it is most likely going to be an inverter cable issue. These may be hard to find for your model.

Think you for your interest on my problem.
Is it possible that the magsafe card is bad and do not give enough electricity to the inverter ?

if it was just a backlight problem I would say yes as that is a fairly common issue on these LED Macbook Pros as they are powered directly by the magsafe board instead of going through the logic board. but the isight still goes into the logic board and not into the magsafe, so it most likely won't be the solution to your problem. you are welcome to send it to us and we'll test it out.

Please, I just need to know if there is a chance to repare the LCD without replace it totaly ?
Can you tell me the possible price of repare. The price of shipping from France is not negligible.

It is difficult to diagnose without seeing the machine. Worst case scenario you would need a complete display which would be around $800 to repair.
