Flashing power light on JVC 48W TV

I just got a JVC AV-48WP74 TV with a problem. When you turn it on the blue light stays on for about a minute with no picture and only a clicking sound coming from speakers. The blue light then begins to flash on and off and the clicking continues. No picture is ever seen.
I want to have it repaired but I want to make sure it is not something I am doing before I drag it off to the repair shop and spend a bunch of money for nothing
Thanks Steve

The front panel has a blue light and power , but i am not getting a picture or sound.


The blue light on the front panel merely indicates that power is getting to your TV. It is likely that there is a failure of the internal power supply

Power light blinks , no picture or sound , just the speakers pulsating.making a heartbeat sound.


Sounds like the TV needs some type of serivice. But just to cover your bases try unplunging it from the power from the wall and let it rest for about 5 minutes. Then plug it back in to the power and try to turn it on using the power button on TV rather then the remote. See if that works. If it doesnt call JVC.
