If the amp has identified a problem within itself, it could be 1 of a million things. Its best to go get it tested. It shouldnt be too hard if the amp has picked it up.

The fan dont turn on when i turn on the tv and the red light is flashing


Hi,
Red light flashing on tv indicates that tv got some problem and shifted to protection mode to avoid further damage.
If Lamp light is flashing on tv then check lamp that would be dead or broke, replace lamp to solve tv problem.
If standby red light is flashing on tv then let me know how many times it is flashing after 3 seconds long pause to provide you helpful info.
Thanks.

Lost the sound and YES my speakers are on and I have moved the bar all the way up to 100% ,,,not even as much as a peep,, the sound was on last night but its off now and I have tried to fix ix it.....


Hi,
have you checked:
1. The audio plug that connects to the rear of your computer (not accidentally pulled out partially)
2. The other end of that cable which plugs into your monitor (usually a red and white plug arrangement, but could also be a small stereo plug)
3. That the speaker icon on your taskbar has not been accidentally "muted" (indicated by a red circle with a slash line)
4. Checked your audio properties (right click the speaker icon) for anything out of the ordinary?

If all of the checks above are good, and assuming your audio cable is OK, I would try and reload the audio driver. You could also try the Windows Troubleshooter. Search your Help for assistance on the troubleshooter program.

Ask me for more help.

Cheers, Steve

Bulb Replacement


It might be the the socket board on this model not the crt tube. Closely look at each tube these tubes end up contaminated. They start looking like lemonade inside. Usually the blue and green, with the tv off see if the green and blue are as clear as the red with a flashlight. You might want to call a service center. Cheaper in the long run over the cost of a tube.

check for the error indicator in the projector, if the bulb light is flashing red, then i think you need to clean the units ventilation fan, if cleaning doesnt solve the problem, you have to replace the bulb.

Flasing red light


The flashing red indicates that either the fileter cover or the lamp cover is not installed correctly. If both are installed properly and secured, the unit will require service.

Won't turn on.. Operation indicator is red, Lamp indicator is flashing red??


According to the E44W48LCD service manual, the temperature indicator red light states the projection TV shut down due to overheating. Red (flashing) states the projection TV shut down, check the cooling fan.
