Question about JVC LT-42X579 42 in. LCD TV

3 Answers

JVC 42 inch LCD HD TV has no picture or sound

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

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

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).

I have a hitachi 50 "plasma that was given to me


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.

The manual for the Hitachi P50H401 TV is available from Retrevo: http://www.retrevo.com/support/Hitachi-P50H401-TVs-manual/id/1233ci869/t/2/ . You will need to enter a code to access the pdf.

I'm assuming you don't have one of the special versions that were intended for large audiences that were only controlled by remote (no control keys on the front of the TV). Remotes.com has the original remote or a substitute remote if you need it. See http://www.remotes.com/remotes/servlet/rs?a=gmi&uuid=13104063628240&smodel=P50H401&brand_pn=HITACHI_P50H401 .

I hope this helps.

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

I have the same model and the same problem... I am told the power display board is is the issue and may need to replacing. New board costs around $80,or a bad capacitor depending on your paitence.

My will not work with the remote any longer. I replaced that. When I manually turn power on, it takes 3 or 4 times before coming on. Then, it will turn off after about 30 seconds. ANy ideas?


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.

Not able to turn tv on with remote


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:

You 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

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

TV turns on for 2 second and then it is off


Your TV may have detected an error. Try first to have the TV unplugged overnight just to clear it out then observe it after turning it back on.

Remote Control won't work with TV


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.
