I want to replace the backlight inverter for model number pcg-61611L but don’t know where it is located

The inverter itself is held to the back of the lid (behind the mounted screen position) by a sticky surface, probably two sided tape, given Sony’s love for taping things in this model. The whole inverter unit can’t weigh much more than an ounce and is easy to replace. Check out the tutorials and you may get to know it: https://www.fonerbooks.com/laptop_8.htm Don’t forget to back up your computer in case any issue unexpected may happen.

I have the same issue. Where is this %#*@ inveter? What if replace the hole screen?
