LCD screen is black, no lights at all. Before this, was having unstable screen brightness. Replaced LCD Inverter but problem still the same. So, I would like to try replacing the backlight lamp. The local...
The Backlight Lamp. I concur with your thoughts that it's the Backlight Lamp. Holding a flashlight at an angle, can you fantly make out images on your LCD screen?
Generally the Backlight lamp goes first. I've found it's best when replacing the Backlight Lamp, to go ahead, and replace the Inverter also. And vice-versa.
To get at the Inverter, the outside Bezel in the front of the LCD screen, is removed. The Inverter Board is right there at the bottom. 2 to 3 wires, couple of screws to remove, and replace, and you're good to go.
Not so with the Backlight Lamp.
Laptop/notebook manufacturers use different terms when describing these parts, but generally it is,
A.Top Cover. When the laptop is closed, you are looking at the Top Cover.
B.Bezel. The thin plastic frame that goes around the LCD screen, in the front. Usually two to three screws on top, and bottom, with 1 to 2 screws on each side.
There is a rubber cover over the head of the screws, and is held on by a rubber cement like compound.
After the rubber covers are removed, and the screws, the Bezel is removed by inserting a plastic letter opener along the parting line, and worked up, and off.
(Pop-pop-pop, as the plastic formed clips made into the Bezel frame, release from the Top Cover)
The LCD screen has a thin metal frame around it. The LCD screen is held in by thin metal brackets. One on each side.
The brackets screw to the sides of the LCD screen, then the brackets have screws that hold them to the Top Cover.
The LCD screen is removed after un-connecting the power cable, and Inverter cable. The bracket screws are then removed, then the brackets themselves.
Finally you are at the point to access the Backlight Lamp.

The tech better be back at the shop, and have mucho experience at this!
Reasoning is, that if one Tiny mistake is made, you'll ruin the LCD screen!
