How to Fix the Glass on Your Plasma TV
Plasma displays contain millions of colored fluorescent lights, called cells, illuminated by plasma comprised of xenon and neon gases. The plasma is located between two plates that sit behind the front glass screen – the most commonly damaged area of the display. Minor cracks are easily fixed by filling them in with a clear viscous substance, such as petroleum jelly. You can gauge the extent of the damage to the screen by checking for moisture around the cracked area. Moisture indicates gas has escaped and the television requires a professional repair.
