Question about JVC HD-52G886 52" Rear Projection HDTV

1 Answer

JVC AV56WP74 Power on: Blue power light illuminates but there is no picture or sound. Power off: After pressing power button to turn off it takes 30 sec. - 2 min. to power off. If I keep trying I can get it to come on with picture and sound. I usually have to cycle power 30 - 40 times. This is very frustrating so I usually leave power on.

Replace the lamp, also the shut down time is correct the unit must allow plenty of time proper lamp cooling. otherwise the lamp life will be greatly shortend. normal lamp life is 3000 hrs.
lamp replacement may require an internal limp timer reset have a qualified tech replace the lamp.

Tv will not turn on i push power on button and blue lights click on an tv acts like it will come on but then tv shuts off and no picture appears


The blue light merely indicates power is getting to the TV. When you press the power on button, the defective power supply shuts the TV down immediately

Loud popping on jvc av56wp74


if the noise is from inside the tv in the back,the high voltage transformer that feeds the anode for the rgb tubes,28000volts probably is arcing.

My tv won"t turn on.


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.

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
