Why do rear projection TV’s turn the lamps off after the picture making electronics?

Posted by admin
Sherminator asked:


I have two DLP TV’s both leave the lamp on for about 5 seconds after the picture is turned off. Surely the DLP chip could survive being turned off after the major heat source is.
Additional, The fan works for about five minutes after the bulb is turned off, surely the bulb would cool down quicker if it was unlit?
