Why does my TV turn on and off by itself continuously when plugged in? (The remote is not being activated)


Hello, there are several things that it could be, but if the set comes on with a picture even for a couple of seconds, I would bet it's the main board failing. Part # is EBT48854401.....thanks

I found it was the HDMI plug-in on the tv that my dvr plugs into went bad. There are two HDMI ports. I plugged the dvr into the other HDMI port and I no longer have any problems.

JVC 42 inch LCD HD TV has no picture or sound


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

What the heck is wrong with my tv??!?!


It looks like the power supply is giving up on your TV. The strobing is because the TV may not be getting enough power or is not being filter properly.
How old is the TV?
