You now have a defective lamp ballast board. It sometimes is the root cause of lamp failures in these sets. The problem here is that Toshiba does not sell the ballast board independently from the larger, more expensive light engine assy. Call Best Buy back and get a servicer out there. He may have to take the ballast board out of your TV and send it out for rebuilding.

Unplug the TV, ensure the lamp door is installed and the screw is snug. Plug the TV in and wait a moment. touch and hold your finger on the power button on the front of the TV. If your TV does not power up, your ballast and power supply should be suspect. Many Toshiba DLP sets use a similar lamp design. They have been known to burst and cause a momentary short. This can knock out the power circuits which feed the lamp. If this is the case, post back for further details if you wish to repair this yourself. I hope this was of some assistance.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php The ballast is the most common failure besides the lamp.The ballast is the one that displays the lamp indicator if it's not able to power bulb or if bulb is not responding.Have a blessed one!
