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

Sounds like a panel issue, you may need a new TV

To start, this TV should not require service remote to access service menu or adjustment menu.

In service menu also there is not a single reset option, but the technician must set the values one at the time.

About the part purchased, I could not find any JVC 87274RS remote control. Please check the number, include any dash or spaces, and include any info you have on the part, so that we can spread light on this.

About the problem it does not sound like something that "just need a reset" it looks like HDMI port is defective, and you should be entitled to get a technician at home if the unit is still in warranty (check it out).

Here how to get in service mode. You use the standard remote. Do not change values in service mode or you can damage the TV:


I uploaded here a service manual for the 40'' of same chassis.I do not have the 42''. Service mode, most parts and functions are the same. Panel size and frame are different.

I am guessing the CCFL tube is starting to burn out. Replacing is not impossible but somewhat delicate process.

Since the TV is that old i would recommend you to buy new TV instead when it goes completely dead.

Return it to your place of purchase and get something else anything else you wouldn't believe how many people are having Issues with the LT series get rid of it.

you didn't say what kind of antenna you have attached to the TV. The antenna is very important and the type of antenna you need is based on where you are in relationship to the television stations in your area. Even being down a hill In the area can be a problem for antenna television. I had to put an antenna in my attic because an in-door antenna could not pick up the signals for the TV stations in my area, I am down a hill.

sounds like the remote batteries could be bad or the buttons on the remote need to be cleaned. some JVC TV remotes, I'm not familiar with this particular one though, can be cleaned using a clean pencil eraser. Be careful opening the remote because some parts can fall out or you can damage the connections to the LED emitter that sends the signal to the TV. Also the solder connections on that LED could be bad.

sounds to me like the fluorescent backlighting is going bad in the top half of your set.

Sounds to me like the digital pixeling that occurs with a weak signal. You have not identified whether this happens on broadcast/antenna TV, cable or satellite service, or a video input such as a DVD. This can be a common problem if you have a weak signal on any of those inputs. In any case, blowing out the dust will not help.
