The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

These 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.

Inverters do fail- look around the edges of the LCD panel for a flat cable & connector.
One may go to the main board but you should find another with fewer conductors to a smaller board.
It may be marked with "TDK" a popular supplier for these.

Not sure why, perhaps it is a licensing issue. You will have to feed it externally using a Kindle Fire Stick, Roku, or Chromecast Device through the HDMI port.

Wi-Fi Protected Setup (WPS) is a standard for easy and secure wireless network set up and connections. Some of NETGEAR's products use the name Push 'n' Connect for WPS. To use WPS, your product must support WPS and be compatible with WPA security. WPS can automatically set up a random network name (SSID) and strong WPA wireless security for wireless routers, access points, computers, adapters, Wi-Fi phones, and other electronic devices.
WPS lets you use a push button or enter a personal identification number (PIN) instead of manually entering a network name (SSID) and password:
  • Push button. The WPS button is either a button on the product or a an option on the wizard or utility screen.

Click on the display button (upper left corner) as a short term fix - it will turn it off immediately - not sure of how to permanently solve this though.

You have to set the playback device on your Vaio to the TV instead of the laptop. You can do this in the Windows control panel under "Sound"
