    The blue power light is flashing on and off and I can not turn my T.V. on. I have tried unplugging it, turning it on with the remote, turning it on, on the side of the TV with no luck. What do I need to do to fix it?

    I have the same problem- tv was working fine last night, and now nothing, just a solid blue light, then flashing and the tv makes a "click" sound like it's turning off. JVC offers no call-in service, only email. very frustrating

    Hey, same here... It is really annoying because me TV is barely passed warranty this month. If anybody finds out how to fix it, it would be greatly appreciated.

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.

    THANK YOU THANK YOU THANK YOU! This fix worked fabulously. After searching through manual, online JVC website, calling JVC, and calling a local repairman this was the only thing that worked! WOW!

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

My JVC LT-42X579 42 in. LCD TV is only 13 MONTHS old and it suddenly won't turn on anymore. The blue power light comes on -as usual- but after 3 seconds, it will start blinking and it will remain that way...


I contact JVC and was told to first make sure your cable box or whatever you use to normally watch TV is powered on and is ready to work
He told me to unplug TV for 10 seconds at least. Then he had me press and hold down the "MENU and VOLUME DOWN (-)" buttons, at the same time for about 10 seconds. Then after 10 seconds of holding the 2 buttons down, he had me continue to hold the 2 buttons and press and let go of the power button. In other words after 10 seconds of holding down the volume down (-) and menu buttons, add the third button (power) and immediately let go of all 3 buttons, at the same time.
It worked for me instantlynd hopefully it works for you!!!
