My screen is not bright I can see picture but not bright

If the picture mode is set to Cinema or Custom, the screen could become dark. If the screen is still dark after the picture quality mode has been changed, change the setting Backlight, Picture, Brightness and adjust the brightness to your taste. ... Depending on such settings, the picture brightness level can be higher or lower

Hopefully alcohol did not short out the inverter. You may simply need to allow time to dry if inverter is not damaged

Hi, Don't put screen in direct sun light or bright light. Bright lights will destroy LCD screen. The LCD screen has some adjustments on back. You might be able to readjust picture brightness.
Good luck.

It looks like the LCD backlight malfunction. Check the backlight voltage, if you have the voltage there, you need to replace the LCD unit, otherwise the main board is defective.
