it is for lighting a LCD screen like a backlight
You can take the LCD out and sell it on eBay or craigslist. Also the board is recyclable.
the design of multilevel inverter can be done by using is the mosfets ....multilevel inverter is the inverter which cna reduce the harmonics by increasing the voltage levels ANSWER: The design of multilevel converter is the same as a single converter. The feedback control however comes from the most hi current output capacity circuit.
LCD refers to integers. The LCD of 15 and 23 is 345
LCD Liquid Crystal Display
LCD of 522 is 522.
Take a closer look at the LCD screen. Can you see a very dim image on the screen? If you can, most likely there is a problem with the inverter board. The inverter board is a power supply for the LCD screen and when it goes bad the screen looses backlight. The inverter board is located inside the laptop display. In order to replace it you'll have to open up the display panel.

This is a common problem for all LCD screen TV. LCD Screen Goes black after a few seconds of turning ON. repeat ... and still the same. You have a faulty inverter causing the back light of the LCD not functioning. Check for a bloated capacitor on the power supply and inverter circuit board. This capacitors can be seen visually by looking the top of the capacitors. If it is not flat these capacitors might be the problem. If you tested it with a multi tester it is OK, but if the TV is power on , capacitors is no longer working as normal. try replacing the bloated capacitors. Also, there are some capacitors that may have causing the problem. Try to replace the high voltage capacitors (light blue in color) located in the inverter circuit board. replaced all $ or 5 pcs capacitor. usually the value are 12pf by 3KV and 4.7KV by 3KV. Goodluck. !! Benjie Ramos (Philippines)
Here are the simply steps you should follow to Remove LCD screen from Toshiba Laptop: 1. Remove two LCD mask seals. Remove two screws hidden under seals.2.

I would Google it (search). Usually I buy them off Ebay.
Usually you can take the lcd have a bright light nearby have something displaying to the screen hold it at an angle and see if you can make out anything that looks like the normal display.
