Laptop display turns off automatically

[ankur625]

Hello,

I have a laptop Comapq Presario CQ61 408 TX

While using, my laptop display gets turn off automatically. I "googled" for the solution. Some experts say its "LCD inverter" problem. I opened my laptop to note down "LCD inverter" model number. But I wasn't able to find "LCD inverter" bellow keyboard or bellow monitor.

My questions are,

1) Is it really the "LCD inverter" problem or may something different?
2) In my laptop model, Does it contain "LCD inverter" or not? (I guess some laptop don't have lcd inverter?)
3) If LCD inverter is there in my laptop, Do I need to open the laptop more to find "LCD inverter"?

Please help me, I can't find the solution for my laptop on internet.

Regards,
Ankur

kenrivers, thanks for the reply. I saw the same video on youtube. But when I opened my laptop, I couldn't find the LCD inverter bellow monitor. Is it possible it may be located under keyboard? Do I need to open my laptop more?

I'm not sure where it is located. If you can locate a repair manual or parts diagram you might be able to find out where it is located.
