Toshiba laptop will not startup

Primer:

An LCD screen does not produce light by itself. It needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, or a series of LED lights.
(Two present technologies being used)

The Toshiba Satellite A215-S7472 Notebook PC uses a CCFL.

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

(Average size is 2mm by 334mm. In inches that is;
Approximately a little thicker than 1/16th of an inch Thick, and a little over 13 inches Long)

A screen Inverter is used to convert the power (Electricity) from the laptop, for the Backlight, and LCD screen.

Point of all this?

90 PERCENT OF THE TIME the fault is a bad Inverter

HOWEVER, the Backlight bulb is located inside the Screen Frame, of the LCD display assembly.

An LCD screen is composed of layers. These layers are held in a specific pattern, by the LCD screen frame.

This is a thin metal frame which surrounds the LCD screen layers, and has Philips head screws which hold the frame together.

NOTE*
The procedure is fairly intricate.

[ So far I have only seen listings for the LCD screen itself, and not a separate CCFL Backlight ]

Go into your bios and set your disc drive as the first boot device. Then put in your windows disc and do a startup repair.
