Question about Philips 55PW9363 55" Rear Projection HDTV-Ready Television
You stirred it up....literally! The projection tubes have sealed chambers and lenses, the chambers are filled with a coolant responsible for cooling the projection tube surface, so the tubes can operate at the high levels necessary to project nice bright images on the screen. That coolant unfortunately becomes contaminated over time, causing the coolant to become "cloudy". Moving the set stirred up the contaminants, allowing the set to sit idle may settle some of the "yuck" back down but the only sure cure is to replace the coolant. The coolant is Glycol based, and therefore is poisonous, much as automotive anti-freeze is, and the old should be recycled in a similar manner. There are many electronics parts outlets such as MCM Electronics, that sell projector coolant if you wish to attempt replacement yourself. It can be a very messy job. It requires a small turkey-baster of sorts with a small hose attached to extract the coolant. Myself I saved a squeese bottle from one of the wife's hair coloring episodes to which I attached a clear piece of aquarium line.That worked pretty well. I suggest that before you start the process that you cover the tv chassis to prevent any of the coolant from contaminating the circuits below the tubes. Otherwise you may turn the set into a giant paperweight.
Post back if you have any questions.
