My problem ranges from a very lound staticy buzzing sound to no sound at all when I try to watch TV. I tried someone's suggesting of unplugging the unit for a couple of hours. It worked for a while, then went back to the really loud buzzing sound.
I tested it both with, and without the cable box.
Interestly though, it gets perfect sound thru the DVD.

is it a scratching sound. that can be a faulty transformer. the magnet inside can come loose an it will vibrate really quick. you will need to locate the one at fault and replace it. hopefully its is just the 2way type as 3-9 way types are expensive when it goes the tv will go dead power in but no power out of it.. they do vibrate when the power is on but when the casing in side goes thats when you can hear it.usually just go **** or buzz and thats it.
This tv have a colors wheel is dying and worn out.The sound u hear buzzing,squiling or lound motor noises.The colors wheel require changing,because it dying and spinning off of it motor axis.Hire a tv Tech. to change the colors wheel,because it sit way inside near the Light Projection Engine it self,require take out many machanical parts even can come to the colors wheel itself to change it.
Something has shorted out and is causing the power supply to overload which makes it switch slower bringing the frequency into a range you can hear. With the age of the unit I would bet on the Horizontal Output and flyback having problems. I have a tip at http://www.fixya.com/support/r4916941-diagnose_repair_projection_tv_high which explains the troubleshooting process and where to get parts as well as what to do if the flyback is not the problem. Good luck. Let me know if you need more help.

Your lamp burst. This model uses a lamp housing which does not have a filter screen on it. When the lamp bursts, hot pieces of glass and mercury (very toxic) drop straight down into the cooling fan below it. Although FixYa.com (implies I'm suppose to tell you how to fix it) I am going to tell you to call a servicer and have them clean that mess out of there. It's a health issue, I don't want someone unknowingly exposed to mercury on my watch. Let the servicer know what he is getting into. I hope this helps.
It is the color wheel. They are usualy less than $150. I recommend having a Samsung authorized service center do the work as it is very difficult for someone without the experience doing this particular job. Labor cost should be $300 or less.
Sounds like the flyback, can you look on the rear tag and let me know which chassis you have and verify your model number and I will post which flyback you need as well as where to get a replacement with free tech support to help you install it.
