Samsung Ln46A50 won't trun on

I bought the Samsung LN46A50 about 3 months ago. It's OK until last week. It suddenly shut off and won't trun back on. But it attempts to trun itself on and the red light blinks and makes 'click' sound for hours.
I unplug the power line, wait for 30 minutes, plug the power line back. It will be fine. Then the same problem will happen again. I called the customer service number and applied the firmware update they suggested. It didn't help. How can I fix it? Please help! Thanks!

    Same problem here. Push the power button, red light blinks and the tv goes "click click" after 15 seconds or so. Haven't been able to get it to come back on. Called customer support, they set up an appointment for a tech to come out. Only had the tv a few weeks, for such great reviews, I'm pretty let down by this.

    Another victim. I thought it was due to the Firmware upgrade i performed on my LN46A650 (a1fxza) and BD-P2550. I, too, get the 'click click', the 5x red blinking light and its cycles every 41 seconds. Just wrote samsung an email to them. Hopefully they can shed some light on the issue.

I use samsung netbook nc110, it works normally until I play a video and the screen goes black and won't come back to normal. I bought it 9 months ago and this begin happening last week. Any solutions?

You can use an external monitor to test it. If the external screen does not display anything, then your GPU and or motherboard is dying. If your netbook works good with the external monitor, then your screen is dead.
You can check the operating system and application using this Norton Utilities:
