Everytime I turn on the Panasonic Vierra TV, it clicks on then it clicks off and the red light under the screen keeps flashing. I have unplugged the tv and replugged it in. Same problem. TV is only 1 week old.

Sounds like 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://electro-medical.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.

Check for bad capacitors (they'll look bloated) on the power supply board. Also check the voltages on the power supply board with your meter ; they should be etched on the board at test point location(s)

try this link for symptoms and cures.

need the model number of the panasonic and also how many times it is blinking. The blinking is an error code.

The power light keeps flashing and the tv won't turn on. If you unplug for a minute and hit the power button it sound like it is coming on then it shuts off and the red power light flashes slowly. The TV is a Panisonic 1080i HDTV, about 6-7 years old.

Try a UHF antenna input to the Panasonic vierra? If the TV is good replace the set-top box?

IC 1006 is faulty on the DG board thats for 53TW models other models it means LOW DC voltage. If you need further info please let me know.

Take it back. If you try to work on it, you will void the warranty. Keever
