Re: Hummm

My tv did this while it was still under warranty. It was diagnosed as cracked horizontal deflection coil.  They replaced the coil.  I hope you can get it fixed. I know it is very annoying.

Hey, first thing that comes to mind is that your cables are faulty.

Possible reasons: the device has a bad connection or bad signal. Or your powersystem is unstable.

Samsung hlp 5063w humming noise

Can you reseat the lamp?  Don't forget to unplug the TV of course, but sometimes the connection between the lamp and TV degrade due to heat contraction and cooling.  Some TV's provide an error code by having LED's flash a certain way, is this what you mean by lights flashing?

HDTV Rear Projection

The color wheel is the most common problem when it comes to noise from DLP's. To determine if it is a color wheel or fan: Turn on the set. When the noise starts, turn off the set. If the noise goes away within 5 seconds, then the color wheel is bad. If the noise goes away after one to one and a half minutes after the set was shut off, then one of the fans are making the noise.
