JVC LT-Z37 SX5

This 2 year old TV will not start up, the power light merely pulses slowly after about 20 seconds. Any ideas?

    I have had this problem with my LT-Z32SX4B LCD for about 2 years. The manual tells us to unplug the AC lead, then reinsert it. If it then works again it is OK. Mine does, but what a dreadful problem to put on the market. NOT a JVC next time.

    It was the Power Supply panel which was replaced, apparently a common problem. Now the HDMI has an occasional audio and sometimes picture and audio drop-outs for a few seconds.

I Have a 2year old JVC LT 24c340 HD which switches off after about 15 minutes , then after a minute or two the standby light comes I have reset the 'TV to factory mode but it still switches off


warranty requirements , on hidden defects.
no defects are expected within 4 years for just domestic use.
call your dealer , write to the importer, about the fault its not a JVC point to make products for only 2 years lifetime.

My JVC LT-42X579 42 in. LCD TV is only 13 MONTHS old and it suddenly won't turn on anymore. The blue power light comes on -as usual- but after 3 seconds, it will start blinking and it will remain that way...


I contact JVC and was told to first make sure your cable box or whatever you use to normally watch TV is powered on and is ready to work
He told me to unplug TV for 10 seconds at least. Then he had me press and hold down the "MENU and VOLUME DOWN (-)" buttons, at the same time for about 10 seconds. Then after 10 seconds of holding the 2 buttons down, he had me continue to hold the 2 buttons and press and let go of the power button. In other words after 10 seconds of holding down the volume down (-) and menu buttons, add the third button (power) and immediately let go of all 3 buttons, at the same time.
It worked for me instantlynd hopefully it works for you!!!

JVC LT-32P679 Blinking Power Light, Automatic Shutoff


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

Picture blacks out after a few seconds after turning on the tv


Anytime an LCD has a shade of pink, that means the CCFL lamps are about to go out. Now that you have a black screen, I'd say you just need some new bulbs.
