Weird problem not convergence

I have this JVC TV and have a problem... for the last couple of months when I switched from any input (i.e. video 1 through digital in) to another input the screen would display either one of three things: 1.A plain grey screen with the bottom of the screen having a bowed black section. 2. A plain green screen with the bottom of the screen having a bowed black section. 3. A really weird vertical scramble sometimes many colors, other times only black blue and green. 4. A screen split vertically in half with one side blank or grey, and the other side scrambled vertically. 5. Plain blue screen. 6. Semi scrambled image in black and white, but looks more like a photo negative. I have equipment hooked up as follows: Digital In - DirecTv HD H20 receiver DVI cable Video 1 - DirecTv HD H20 receiver through component cables.(as a back up) Video 2 - Playstation 2 with component video Video 3 - Sony DVD with S-Video On screen menus work fine Now, the tv won't even display a picture except for one of the above things. It used to fix itself by cycling the power but now it just doesn't work. Any help appreciated

I have an old JVC RX6022V audio receiver. We sold the TV that came with it and purchased a brand new TV. The place I bought the tv sold me a digital audio cable. I switched the tv to external speaker...


If your new TV has a digital audio output, your old JVC receiver probably does not have a corresponding digital input. One or the other has to be changed. Look for an EXTERNAL AUDIO output with RCA connectors on the rear of the TV.

Jvc hd56g786 channels stuck on digital cant get them changed to analog


Using the television's remote control, enter the user's menu. Search for video input and change from cable to antenna. If still experiencing difficulty, visit the JVC website and download the owner's manual to learn the procedure of changing the video input type and deactivate the television's digital decoder.

JVC 40 inch LCD digital inputs (1 and 2) no longer works. Standard video and component cable inputs work, but not HDMI. Please help


This TV has a sensor that deactivates the inputs when light is sensed. perform this procedure to correct it:

1. press "Sleep" button on the remote
2. while "Sleep timer 0" is showing, simultanuously press "display" and "video" button on the remote
3. you should be in the Service menu of the TV....if not you should do the steps again
4. select "self check" from the displayed options.
5. when the "self check" menu is displayed, Power off the TV.
6. unplug and replug the TV.
7. Check the digital input.

if the input never worked for you, it is possible that you have the DVD/Bluray/whatever set up incorrectly. I don't think this TV accepts 1080P resolution so make sure it is set to 1080i or lower

JVC LCD TV (LT-42X688) input panel not working!


1. This TV has setting for the HDMI input that allows you to select the HDMI Audio or Analog(red/white wire) audio. Make sure this is correct

2. Most cable boxes are DVI not HDMI. If DVI then you actually do need to use those Red/white cables. If HDMI, refer back to #1.

3. The cable box has a setting to select the Audio output, HDMI (digital) or Analog(red/white cables). Just like #1, this has to be set.

4. Contact your cable company to help you set up the box correctly. JVC can probably help you check the TV

Cannot get 27" jvc av-27530 tv to recognize playstation 2


Do you have the remote? You will need to cycle through the inputs to get to video 1 or 3. You might have the buttons on the front of your tv that says tv/video or tv/vcr. If not go down the channels past 1 and it might automatically switch through the video input selections. For any of these solutions have the PS2 plugged into video 1 and turned on. Hope this helps.

at JVC Support Page , download owners manual , listed above , on page 35 , it appears you should press INPUT button and cycle thru TV / video 1 / video 2 / V2 component / and video .

depending what video input option you used to hook up your Xbox to , you should be able to figure it out from here.

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.

I just bought a JVC THD50 surround sound system. I want to hook up the system to my television and cable so when I watch cable I can hear the surround sound. I bought a digital optical audio cable and...


See below for the correct setup to get the best clarity sound possible.

From Set top box:
  1. Audio: optical or digital coax cable output --> jvc system Input
  2. Video: hdmi output--> jvc system input
From JVC System:
  1. Video: HDMI output---> TV HDMI input
TV:
  1. only accepting HDMI input from JVC System.
This will provide you will sound from your jvc system at all times. Your JVC system is made to be used as a hub. So essentially what you are trying to do is connect all components into the JVC system. Then only connect the video portion to your TV. The TV itself should NOT be emitting sound.

Note: You may need to turn off the speakers in the TV setup menu to acheive no sound from the TV. This will make for the ultimate experience.

It sounds very much like your receiver needs repair by Sony.
