Question about JVC Televison & Video

1 Answer

I am working on a JVC tv LT-42XM48. Works fine with the external antenna, but gives me a "no signal" when using hdmi ports. I tried diferent devices, diferent cables. Also swaped main board(purchased replacement on Ebay), problem persisted. Should I suspect that my replacement was also bad, or is there any other component that could cause the problem? Thanks for your support.

SOURCE: PS3 been working fine over

TV Connectivity
The issue of connectivity between the PS3 and the display is very complex and depends on the type of TV (Analog, Digital or HD Ready), the maker of TV (until recently, only Toshiba TVs have component AV connections as standard in Europe, most other Euro TV sets use SCART which can not carry an HD signal) and specification of TV (the very latest HD Ready TV sets have wider connectivity options than earlier HD "capable" TVs from the same manufacturer which may have lacked HDMI), and finally the configuration of the PS3 model purchased.

SOURCE: my hdmi port is not working

I have Verizon Fios and there's a known issue with the motorola HD boxes that they have bad hdmi ports, the screen goes green and that's it, nothing I can do about it I just use component cables. You need to be sure it's your tv not the cable box. Try the hdmi on a dvd player or ps3 or whatever else you have first just to be sure it's the tv at fault not the cable box. If you determine it is the tv you need to replace either the main board or the video board depending on your specific tv model. Some have the video inputs on the main boards some have video boards.

Any HDMI cable manufactured in the last couple of years should all be HDMI 1.1 compliant, your problem is most likely the logic board in the TV itself or the HDMI connector on the logic board has a bad connection..

Have you tried hooking-up a standard DB15 VGA cable to the AKAI TV and your laptop?

If this works your problem is in the TV and will most likely have to be repaired to receive the HDMI signal since your Panasonic DVR and your laptop are not recognized by the HDMI input on the TV.

Good luck!

After reviewing the service manual for this set, the problem is is in the DIGITAL BOARD. To get the right Digital Board you will need the Version number of the TV.

Good luck

Why is my tv jvc hd70zr7j showing a blank black screen when i connect the hdmi signal cable? the ps3 used to work fine before but since i moved into a new place it just shows the black screen


you have a HDMI port Failure that's not uncommon many people fail to turn the units off before switching cables around it only takes a momentary short on the 5 volt line to one of the other lines and it can short it . or it may just be a normal failure . but you would have to change the .with the AV and HDMI ports on it to restore operation . your set probably has more then one port ? have you tried the others . by process of elimination you have ruled out its the game and cables so it points back to the tv

No optical output except when using ipod dock on tv


Unfortunately, there is a limitation on the JVC LT47P789 digital optical audio out. This audio output does not get the signal from any HDMI source. This is described on page 49 of the user manual. The manual is available from JVC here: http://resources.jvc.com/Resources/00/01/14/YA653ien.pdf . There is a similar restriction for the analog audio output from the TV with the HDMI inputs.

If you use the component audio/video inputs on the TV from your set-top cable box and DVD player, then the optical audio output will work. Otherwise, you need to find a way to connect the audio directly to the receiver. Some receivers have multiple HDMI input ports. These then forward the video signal on their HDMI output to the TV. Another option is to connect the analog audio outputs from the cable box and DVD player to the receiver. This may require resetting the Audio output from these set-top boxes to keep from sending the audio over the HDMI cable. With the Cinemate, you might need some sort of audio input switch or an HDMI converter and switch that separates the audio from the video signal.

I hope this helps. Please add a comment with more information about your devices for ideas on how to work-around the problem with this JVC TV.

Also, this TV has a circuit that deactivates the HDMI if the rear cover is removed. It is possible the HDMI may have been turned OFF. This is reset in the service menu of the TV.

No video input -- all ports -- for JVC LT-37X688


JVC may allow warranty exception or some accomodation for 15 days out. You have 2 seperate issues

1. White lines spreading is probably a video process problem. I think this TV has 3 Boards inside. Middle one is most likely suspect followed by the one on the Right

2. HDMI input not working is because they were turned OFF. JVC TV's have a sensor that will shut off the HDMI if the TV's back cover is removed. This must be reset in the Service Menu.
