Sounds like power supply problem (either poor connections or bad capacitors).sometimes they look deformed or you have to check them with an incircuit capacitor tester.

If your LCD is less then a year old, I would suggest to contact the manufacturers to have it fix under warranty.
The failure on your LCD could be a defective back light inverter or a power supply not providing enough power to the back light inverter board.
Let me know if you require further assistance.

I would like to know who makes the Insignia TV? Thank you


They are made by " XOCECO" in China.The link is :
http://www.asia.manufacturers.globalsour...

XOCECO = Xiamen Overseas Chinese Electronic Co. Ltd.
They also are sold under the name " Prima ". Their link :
http://www.xoceco.com.cn/eweb/index.asp... Insignia is a brand made & sold exclusively by Best Buy Stores. It's like their "in-house" brand. Same as if you bought Meijer brand ice cream... it's their "in-house" brand. A lot of companies throw surplus parts that are sold to budget manufacturers who assemble and distribute the finished products at a low price.

Depending on which model Insignia you have your eye on, the manufacturer could be up 7 different companies. Xoceco Co. distributes them to Best Buy (they're an importer, but not a middle man because they're regulated by Best Buy Inc.)
A majority of the parts are from LG (and they also produce all the ATSC tuners for every HDTV built-in TV on the market and a plethora of other TV's), Philips-- which also has ties with LG-- and Toshiba has a share in creating the TV's as well.

The same goes with brands like Vizio, Olevia and Westinghouse. Although I would choose an Insignia over any of these brands anyway because Insignia is a proprietary Brand name for Best Buy, and Best Buy supports and services all their products. Some of those brands are built from refurbished models that were bought in bulk from service centers, clearance centers, TV repair shops and are also made from surplus parts.

Insignia is a good TV, but I would not recommend using it as a main TV. It'd be perfect for a bedroom or a kid's room.

Problem with tv turning off by itself.


I had a friend with the same problem. He had to clean the components and fans in the set. The accumulated dust had caused the set to run hot and a safety switch was the tv off. He purchased a few cans of compressed air and, as he blew the components and fans out, used a vacuum to capture the blown dust. Good luck.

Turns off after a few seconds


The unit is going in to shutdown. There is a short in the unit. My guess would be the HOT and or Flyback are bad.
