There is a story circulating that the semiconductor chips made by Texas Instruments contain so many toxic chemicals and are out-gassing fumes that they can be used to exterminate bugs simply by tossing several TI chips in back of the refrigerator, back of under-sink cabinets, etc. The term "TI Inside" has come to be a warning label meaning 'Toxic Instruments Inside'.
The DLP (Digital Light Processing) chips from Texas Instruments used in projectors and televisions have a glass window, a 'getter', and a special atmosphere containing 17 different gases for lubricating the aluminum mirrors. These are very large packages. The gases leak from the package. HD1, HD2, HD3, 0.7xXGA, 0.9SVGA, etc.
"All DLP projectors run hot, and I suspect this heat produced an unusual amount of outgassing from the Sharp's internal components."
"This outgassing causes contamination on the color wheel."
The bugs behind your refrigerator are like the mine canaries of years ago. When the bugs die, it's time to get the TI chips out of the house.
The TI Inside (Toxic Instruments Inside) warning label should be printed on everything using TI's DLP chips, e.g. , your DLP projector, your DLP TV, etc.
