Question about Insignia IS-LCDTV32 32 in. Television
My 37 inch flat screen has a constant buzzing sound and a purple bar that goes up and down the screen
SOURCE: buzzing emitted by vsx-409
Could be the result of having DTS compatible equipment connected through the analog inputs on the VSX-409D. Noise and distortion will result as essentially the DTS signal is being played back undecoded. If this is the case you'll have to connect your LD or CD player through the digital connections (coax or optical) and set 'Signal Select' (button on front) to 'Digital'.

It sounds like an Intergrated Circuit (IC) has fried.
Your best bet in this situation is to contact ur tv service operator and let them recommend an authorized service center in your area....

Make sure you have a ground prong on your power cord. Most input jacks nowadays are closed circuit. They have a switch built in that won't allow any sound without the cord plugged in. You may have a damaged jack that will give you a loud hiss, a loud hum or crackling depending on what volume your controls are set at.
