Is my brand new TV fried

probably drew moisture wherever it was stored.

You missed one tiny bit of needed information, what is the brand and model number of this set?

Is it repairable, well, this question can be answered only after opening the back cover and evaluating the damage. From you side, please connect the TV to a different power outlet where other similar devices are working and see. Then try changing the input device to something that sure works. If it does not work even then, this may need attention by a qualified service technician.

There's something wrong in the power source of the tv , very bad sign on a tv just 2 weeks old. Just take it back, not worth the hassle.

Those blinks are fault codes. To know more visit the site linked here. http://electronicshelponline.blogspot.com/

Please read these replies to the same problem. A new power board costs around $284.00..

still nothing, tried twice last night and second time tv worked, this morning nothing

Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.

The black screen with audio working ok is the inverter card.
Just replaced mine. It is CMO part number VIT70002.00

The inverter provides the high voltage necessary to drive the cold cathode lighting.

A new card is about $180 but shud save having to dump the set.
Card is located on left side of the display (as viewed from the back).

Is the light blinking 7 times on front of TV ? If u take the back cover of the TV off you should see two leds on the bottom right of power supply turn on when u push the power button. When the TV go into error protection on the upper left of power supply you should see. A blinking green light. Please inform me of the error it flashes and ill will be able to help further. ( Serveral possiblilties it could be from audio, bad power,and faulty Y-main.)
