When I turn on my 42" NEC LCD tv, the green power light comes on, but screen does not. Then the tv starts making a fast clicking sound. After 30 seconds, tv shuts off. What can that indicate?

I had this same exact issue yesterday. I own the same TV model and here is what SONY had me do to get the picture back. Ultimately the picture comes back, but it will be very dim and needs repair. Most likely a power supply issue. Try these steps:

-Press power off or leave with standby light on for 5 minutes (wait the full 5 minutes)
-Unplug TV / Press top buttons 5 times each to remove static from system boards (yes, each button 5 times each)
-Wait one full minute and plug TV in and press power on

SOURCE: JVC 42 inch LCD HD TV has no picture or sound

utencilio posted this fix. It worked for my JVC LT-42X579.

Okay, I found a fix! Called JVC, spoke to somebody there, here it is:
1)unplug the TV completely, no wall no power strips, completely
2)wait 10 sec
3)plug TV back in and Turn it on, the light will still be doing the same thing
4)wait 30 sec
5)ON THE TV, not the remote, locate the menu, volume (-) and power button.
6)while simultaneously holding down the menu and volume (-) button, pressed the power button ONCE and continue to hold the other 2 for 10 sec.
7)on the remote control, go to menu>settings>system info
*** now this I know as a FACT will work on systems that display: JVC - ver.5.32FO001, but I don't know of any other versions***
8)press the mute button on the remote twice
9)unplugg TV again and wait 10 sec.
10) plug TV in and turn on

It SHOULD be working normally now... Thanx to the guys a JVC support for this one, I know it seems like an obvious first place to look, but sometimes it isn't. I for one checked online forums first

Spetroniq 42"lcd screens black no picture no

Sounds like maybe power supply, but I would check with flashlight 2 in from screen when the green light comes on to see if you have a picture, if so then you have a bad inverter board, if not then power supply problems. You can look for bad or bulged caps in PS

LG 42 LCD no sound or picture

Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.
