TV worked fine two nights ago. Turned on today and no sound or picture. Blue pilot light under center of screen always on. Any ideas?

Lessing of brightness on a DLP set is a sign of imminent bulb failure.

A new bulb is in order.

Nothing to worry, You change to AV mode to TV mode and wise verse,
If nothing happen then call the service center, It only two months old.

LCD's use a colorful crystal see through display which only visible when light is shining through it. if you have sound and no picture it's always a faulty PSU. Very easy to change out actually.

Replace the lamp would be the first thing to try.

Unplug,replug an hour later,might reset to factory setting.Tries stop all timer setting.

I don't know what model you have,but... I have a 50v715 and it was doing the same thing and it turned out to be the lamp. So if you have not replaced the lamp in a while then it could just be it time. Hope this is helpful.

Sounds like the inverter for the panel for the left side is defective.

I too have the same problem with the blue screen and also some dots in the center of the screen. I went to the sony site (www.sony.com) and found the answer. They will repair the unit until Dec 31, 2008. hope this helps

Does anyone know where can I buy a screen for a 27" LCD Insignia TV. Model is NS-27LCD? My screen creaked. I checked out e-bay and have not found a broken TV with a good screen. Does anyone know where I can buy a screen at. 
Thank you all for you time.
