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
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

If you are trying to use a combination of wall switch and pull chain control, the simple logic in the receiver can't figure out what to do. Try disconnecting all fan power at the source, removing and reinstalling the remote battery, restoring power, and trying all combinations of switch settings and power off - power on operation until you get results (or give up).
First do you see a light indicating that the TV has power? There are two power buttons on the TV (the main power and the regular power button). The red standby light will light up when the main power switch is on. This indicator is just to the left of the remote I/R sensor. You can find the main switch on the bottom front of the tv (it is under the tv forward of the stand). Turn on the Main power if it is not on. Then try the power button on the control panel of the TV again.
Does the standby light change color or blink? (Red is standby, orange is power savings (no signal), blue is on.) If the main switch is on and the standby light doesn't come on, the TV has a problem at the power supply. Try unplugging the unit for a bit (at least 30 seconds) and then plugging it back in. This will reset the internal circuitry. If you see a blinking light, then the TV is reporting a self-test failure. I do not know the codes for this model Hitachi Plasma TV.
It could be the temp sensor going bad. This sensor sits on top of the
metal housing which the bulb assembly slides into. The bulb assembly
will have a hole on top and this is where the sensor is above. There is a
small blue and white wire that plugs into it. If you pull the wire out
and put a paper clip or wire in the coupling you will basically bypass
the sensor connecting the blue and white wire. If your tv turns on then
that is your problem. Its cheap too. Here were my symptoms..1] Turn tv
on 2] Bulb would light up..(which eliminates the ballast) regular
picture would show up (which eliminates the bulb and color wheel) 3] 30
seconds later tv would shut down with 3 flashing lights. After bypass
the tv turned on as always and hasnt shut down yet. Always un plug tv
first. Get the replacement part to avoid overheating and possible fire
There is an infrared sensor inside the tv to receive infrared signals transmitted by the infrared signal generating light emittin diode fixed on your remote control. Either the sensor inside the tv or light emitting diode in the remote controller faulty, remote function will not work. For manual operation troubles, check the wall power socket of plug of the tv is faulty, loose contact etc.
First try changing the batteries. Next make sure when you press function on the remote control the red light on the remote displays under tv
Next try a remote reset:
have to unplug the television after turning it off. Take the batteries
out of the remote control. Point the remote toward the remote sensor
(bottom right hand corner of the television set). Press the power
button on the remote control and hold it down for 30 full seconds. Next
press and release every button on the remote control. Next plug the tv
back in and power it on from the power button on the television itself.
Replace the batteries. Adjust the volume using the remote control. If
that works the problem is solved. If it doesn't work you may need a software update, a new remote control, or repair to the sensor on your television.
To see if your remote control is working look at it through the viewscreen of a digital camera.
The digital camera must be turned on and ready to take a picture. Next
press a channel button on the remote control. Do you see a bluish white
light? If so the remote control is ok.
The following steps should be able to correct the problem: 1) Unplug the TV or remove AC power from the TV 2) Count to ten and then plug in the TV 3) Locate the [Menu], [VOL-] and [Power] button on the TV’s side panel 4) Using the buttons on the TV’s Side Panel, press and hold both the [Menu] and [VOL-] buttons. 5) While holding those buttons, press and release the [Power] button one time and count to 3 before releasing the [Menu] and [VOL-] buttons. 6) The TV’s lower left Blue Power LED will come ON. 7) Wait 30 seconds. Confirm that the blue LED on the Lower Left of the TV (not the iPod dock for iPod models) has remained ON during this time. 8) Press the [Mute] button on the TV remote twice 9) Unplug the TV or remove AC power 10) Count to ten and plug the TV in 11) The TV power should automatically come ON and the blue power LED with be ON 12) Wait 40 seconds and the TV picture should appear 13) You can now continue using your TV. 14) If the picture does not appear, power on the TV manually: · If the LED begins flashing, unplug and power ON a second time. · If the LED begins flashing again, power ON the TV without unplugging If the LED begins flashing again, contact us directly by phone to obtain a local authorized service center for you. If the TV does power on, please reply back with the software version number for us to research this issue. Please follow these steps to obtain the software version number:
1) Press the [Menu] button on the remote control. 2) Using the arrow keys in the center of the remote, scroll over to the "settings" menu and select the [OK] button on the remote 3) Scroll down to "system info" and select [OK] button on the remote
1. Hold [menu] and [vol-] button on the side of the TV
2. while holding these, press the [power] button on the side of TV (NOT remote)
3. blue light comes ON and stays ON
4. wait 10 seconds then let go of [menu] and [vol-]
5. wait another 30 seconds and some type of picture should appear
I think this is right. I got it from the JVC call centers guys so sorry if I missed or messed up a step.
Nothing was wrong with the remote in the first place! The problem is in the TV. Some use a sensor that sees the Infra-Red light from your remote, others use an IR phototransistor. The signal then goes to a controller that performs the required function. Check the IR sensor on the front of your TV first. You can confirm operation of your IR remote by pointing it at a camcorder with night-shot and pressing the button.
