I have the same question as everyone else. ! problem tv will come on a screen(blue) stays on for about 3 sec then it turns of with the screen being green

if its a projection tv it has to warm up an cool down when powered up or down an it will take about 90 secs for each or more

Likely a main board issue in the set, but unplug set and box if used for a while, power back to see if a reboot has any effect.

try with restarting computer & press F8 at the same time. u will see a menu where choose "safe mode" & start the computer. in safe mode see the display properties, set the refresh rate & resolution according to monitors specifications, apply & restart again. if that does not work, replace the main board of lcd monitor.

The green crt is dawning to much current, and that is why the TV is shutting down, if you remove the speaker cover, there is a focus block, that has six controls, on it three are for red blue, and green screen voltages, if you turn green down where the retrace lines go away, the TV should stay on, it is not worth fixing, you would be better off getting a new LCD.

check for bent pin on plug.....

One or more of the CRT colors guns it dead,must be replaced.

might be a crooked flyback transformer, first check for shorted transistors around the transformer and components at the horizontal output stage..

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.

Unplug the three red-blue-green plugs nest to the convergence amps. If the unit powers up and stays on the picture will look bad but will confirm that the convergence amps have failed...
Replacing the amps and one or more resistors in the yoke return will restore the set to normal operation..
Use only Sanyo original Ics..
