I am having old HP TOUCHSMART 520 - All in one PC. The display is having some issue with white cloud like patches. I would like to use this display for photo frame with raspberry Pi. Attached the images.

Can we fix/clear this patching by opening and cleaning the LCD display? I am also seeing some fluid like drops on the screen? Is it LCD fluid leakage? Is it any risk (toxic) involved in give a try to clean inside the LCD display by opening it?
