LED backlight screens do not utilize a florescent lamp and inverter circuit to power it. These LED Screens have a pattern of LED’s (light discharging diodes) behind the liquid crystal monitor. LED screens do not have a Power Inverter Motherboard". In a lot of cases, the business accountable for the manufacturing of the LCD screen is not the like that of the computer system.

I have a Toshiba M105-s3041 (14.1 screen) laptop computer that has LCD Issues. I say this since that is what occurred to me. I laptop became a brick for a week or so up until i chose to replace the invertor from another busted laptop just to figure out that the clips which keep the screen closed were broken and lodged in the switch which avoided the backlight from working. Following the guidance here and on other web sites, I ordered a replacement screen first.
When your computer screen goes black arbitrarily, you are left in the lurch as absolutely nothing shows up on your monitor screen. The age of CRT (cathode ray tube) shows is over and LCD screens are currently being replaced with LED screens. I can not tell without testing the laptop with another working screen.
The screen headed out once again (still poorly visible), the inverter was replaced, and the screen worked for a day. However when I push the LCD inverter it reveal a white screen with absolutely nothing. My LCD on my IBM went black one day while it was booting.
