Re: tv shut off and wont come back on
Your TV is going into some kind of a protection shutdown. In todays tvs just about anything wrong anywhere and the tv will do what it is doing. Unfortunatley there is probably little you can do yourself to track it down, probably need a pro.

I have found that the solder connections get loose where they connect to the p.c.b. please make sure its not plugged in and don't touch the hv probe going to the tube. It will be the last time. Be extremely careful and keep one hand behind your back. If that's not it, the power supply has gone south. Get another TV.
Try draining the power of the computer first. completely shut it down by pressing poweer button for like 5-7 sec. then unplug power supply from the outlet. then press and hold power button for another 15-20 sec. After that, plug back in the power cord, and turn computer on normally.
Try typing your model tv along with the words "trouble codes" This could be a code 22 or a 2. Sounds like a bad connection or bad component failing such as capacitor or resistor. The tv may be shutting down as protection against what it senses as a power supply failure.
This is an on-going problem with DLP sets. Normally you shut the set off and the cooling fan cools the lamp down and then it shuts off. In your case, of which it's not your fault, however your lamp has taken a major hit by not properly cooling down, in turn, you need to replace your lamp at this time.
I suggest in the future if you have an electrical storm and a chance of a power outage while your watching tv, I would'nt play that model or any other model of a DLP set.
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
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
When you adjsuted for the blue you were actually adjusting the voltages to the CRTs (lamps) which in turn shut them down. You will need to turn each one of the dials up agin untill your tubes stay lit, then the coolant in the green and blue CRTs will need to be changed as the green evidently is contaminated thereby making the blue dominant. But when you turn down the G2 controls your actually turning down the High voltage to the picture tubes thats why they dropped out on you.
It sounds like the TV may have a shorted CRT, picture tube, but let's trouble shoot:
1. Unplug TV from wall.
2. Remove speaker grill, two on bottom, the screws are covered with plastic caps, right and left side on bottom next to floor.
3. Remove inner panel.
4. The blue tube is the one the right side, remove socket, with phillips driver, make sure it's not touching anything.
5. Plug and turn TV back on, if picture appears with no blue it's the tube.
6. If still shuts down, bad blue CRT driver IC.
CAUTION: Call a factory authorized service dealer to give you an estimate, if this sounds too hard.
Good Luck, Day, Big Irish.
