Question about Vizio Televison & Video
As you mentioned that power light blinks for a half a second and does not come on, confirms that this is an internal hardware failure.However, in most of the cases it is due to a bad IC in the power supply unit.If you have experience in repairing electronics, could read schematics and would be able to keep precautions, you could open up the TV. Locate the power supply board and on that you could see some bulged / fused / swelled / leaked capacitors. De solder them and buy the same value caps from Radioshack or Fry's. Re solder them properly and you could fix the problem.
Other than this, it needs more advance troubleshooting which would need other testing equipments.You could revert once you check the power supply board and we could further continue.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
