• Reset component settings. Usually, the problems you encounter with a projection TV may be resolved through the resetting to its factory settings. If you experience inaccuracies in the color, reset the television's PerfectTint/PerfectColor capabilities. Simply press the Menu tab and then highlight "Perfect Color" using your right key arrow. After this, press "Enter" and then "Reset" in order to reset to factory settings. If you have audio / video problems (VCR or DVD player), simply press "Menu" and highlight the "Reset" option.

Reset television controls. In case you cannot fix your TV via its component settings, there are other ways of resetting. Just select "Menu", key in "1, 2, 3", and then press "Enter." In doing this, the TV's manufacturer's specifications will all be restored. If your TV's power system does not function, you should perform a complete system reset. You can do this by clicking on Reset System button located at the TV's control panel. Your television will be turned off and then a green light (LED) will quickly flash for approximately one minute. Once the light has stopped flashing, your TV should immediately turn on.

If you have never replaced the lamp then I suspect that first as fans starting up means the power supply is working ok. The lamp may look good but is failing to fire. The part number is TS-CL110UAA.

Try a hard reset by unplugging the set for 30 secs. Then, go into the remote and make sure speakers have not been turned off.
