Question about JVC LT-42X579 42 in. LCD TV

3 Answers

JVC 42 inch LCD HD TV has no picture or sound

When I turn my tv on, the blue light (remote control sensor light) comes on and the tv clicks like it is going to come on. After about 30 seconds, the tv will click again and the blue light will start blinking. No picture or sound comes on. We had it on earlier in the day and it was fine. We came home that afternoon and turned it on and this is what it did. Any ideas what is wrong?

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

Tv will not turn on i push power on button and blue lights click on an tv acts like it will come on but then tv shuts off and no picture appears


The blue light merely indicates power is getting to the TV. When you press the power on button, the defective power supply shuts the TV down immediately

Philips 42PFL7422D/37 42-Inch 1080p LCD HDTV Picture went out but still have sound. Any tips on how to fix it?


If the backlight of the LCD-panel does not function, (no picture) then Master and/or Slave inverter are defective. Inverter boards are screwed to both sides of the LCD display, if they have revision 1.2 boards then they will need replaced with revision 1.3 boards.

Jvc tv wont come on.


your lamp is burned out-easy and fairly cheap fix. Order a new lamp and install it according to the instuctions sent with the lamp.Dont believe that you need to take it to a service to have it fixed, this should be less than $150 fix-good luck
