I have an insignia 32in lcd flat screen tv, it's about a year and a half old. The sound is working but there is no picture. It will not even display the dvd or xbox picture. If anyone can help me figure out what is wrong I would GREATLY appreciate it! Thanks for you time.

The first thing I would try is to disconnect the tv from the power source. Wait five minutes before plugging it back into the wall socket. Turn the tv back on and see if you get a display. Try changing the channel and switching inputs. See if you can get it to display anything at all. You could shine a flashlight at the screen and see if you can make out an image. If you see an image with a flashlight then your backlight is out.

Is your tv less than a year old? If it is less than a year old you are still under the manufacturer's warranty. I would see if Best Buy would honor the manufacturer's warranty in store. If that is not the case they should give you a number to contact Insignia directly.

If your tv is out of warranty, it may be cheaper to replace it. I would do your homework and check the price of a repair vs the price of a new tv.

Won't not want.
Hi James,
If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
Check the cables, connectors and connections.
If your TV, flatscreen, or monitor is more than 5 years old it is more like to have suffered a
component failure.
Take it to a repair shop.

At 8 years age components are wearing out. It sounds like a power supply issue. It is not cost effective to repair.

Change input device to some other like a DVD player. Look for loose contacts in RC jack, cable, sockets. Look for any jammed buttons on TV or on remote.

Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, call in a qualified service technician.

your mainboard is deffective...go to service center for spareparts

I also have the same problem on my 42" Vizio.

Is it under warrentee?
It sounds like the main fuse inside blew. Does the outlet work at all?
If not, reset the circuit breaker or if it is on a power strip, reset the strip trip switch.

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.
