There is a simple way to clean your LCD panels without the need of expensive cleaning solutions rather you can create a new homemade cleaning solution. Mix Vinegar/Iso propyl alcohol (IPA) with distilled water. Spray the solution to a cotton handkerchief. Clean the LCD panels with the cloth such as no pressure is inserted to the LCD s. Do not finger the LCD panels . Doing so will make your LCD pixels burn out. Clean the LCD s in one direction (ie Top to bottom). Hope this will help you…..
