Display backlighting went out once...now back again

Hello ifixit,

Today as I was working something happened. I had turned the display brightness to 100% for about 5 mins or so when the light suddenly went out.

I tried to connect an external monitor and it was working. Then I took a flashlight and pointed it directly to the display.I found that the display is OK, but the lights were still out. The Apple logo on the lid was off as well. I was very upset and I left it like that wondering what could be done and was gone for about 10 mins or so. When I came back , lo and behold ... the light had come back on .

However, now I fear that it might happen again! So what do you think, what could be the problem, the inverter board or the display CCFL?

I stay in India, hence if I have to order for a component, and if it is not the faulty one, chances are less that I would get to return it back and order the correct component.

So please help me, ifixit ... I know you are the only one who actually could do so ...

Many thanks in advance,

Nirmalya .
