When i boot the Laptop the screen flickers but i can see that windows loaded is there a battery for the screen?
The issue may lie in either the inverter or the backlight bulb working intermittently, or some cables are loose. There is a repair guide in the device page for the screen. You can also use the guide to check the inverter and cables while taking the screen out. Toshiba Satellite C55D-B5206 Screen Replacement
