In some cases, there are minor defects in some parts of the screen. Points that do not light, points with
brightness different from that of the periphery, or points with color different from that of the periphery.
Some pixels will always be on or always off. Please note that this is not a malfunction. So what this says is that it's not the Plasma Cell problem, its more like a bad board inside. You will need more info like schematic and find out which area the bad part is in.

First thing to do is the reset and the whacking test. I give this a 50/50 chance of clearing it up.
ONE: Disconnect the power cord for 4 hours. Then when you power it back up the internal soft codes will automatically reset to factory defaults.
TWO: The whacking test is to just bang or smack the set with your hand on the back, side, top, etc., to see if there are loose connections or cold solder joints inside that are acting up. If so, the banging should knock them back to normal and the set should restore. You might have to use some creative banging and some have had to put a book or magazine under one corner to torque the chassis enough to get it to work reliably.
If these two procedures do nothing then:
The manual always knows the best.Go through the manual carefully and u will find the solution to ur problem..
Goodluck and Kind Regards

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 one of the front panel buttons is jammed. press each one and see if any fail to "rebound" or feel different from the rest. You can usually work the button in a 'circular motion" to release it. If the buttons seem normal , it's possible that the switch inside the TV has collapsed
