No power i have an insignia model #ns30htv was working fine unpluged moved to new location when i pluged back in nothing happened

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Make sure ther's power in the outlet by plugging in something youknow it works ,if there's not pewer check the breakers.

check electromaniac.com and download a service manual for your tv set good luck

I just had the same problem as everyone else. I had a brief power loss and our new Wii system's power would no longer work. To fix the problem, I unplugged everything from our Wii and unplugged the power cord from the outlet. I let the system set for 10 minutes and re-plugged the power only. That did the trick. Then I was able to plug everything back up and we are now back to playing.

Supposedly, doing the steps above resets the Wii according to the Nintendo online trouble shooting guide.

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.

I had the same problem. Unplugging it and plugging it back in fixed it.

this is a very common problem among these projection tvs and the best thing to do is toss the damned ting out. i myself had a panasonic tv and it never turned bac on. i waited over 2 months and neer turned on. the lamp in the back has blown and its very costly to fix due to they dont make these tv no more.

Does the power supply have its own power switch?

It is located next to where the power wire plugs into the back of the PC.

If you hold the power button for 20 seconds it will shut off. I had the similar problem where I unplugged my Insignia NS4V17B frozed on the bluetooth initializing screen. I turned it off then back on and it is now working fine.
