Question about JVC HD-52Z575 52" Rear Projection HDTV-Ready Television

HDMI input failure

I finally decided to upgrade my input to HDMI once my cable company got a new box that had HDMI out. When I hooked up the TV the HDMI input gave me only a black screen then after plugging it in and out a few times gave me a green screen. I know the box and cable work since I hooked up another TV and it worked fine. I called JVC and went through the whole HDMI reset without any luck. They said I need to get this serviced, but I really don't want to pay for this for a TV 3 yrs old, especially since it obviously never worked from the beginning (I just never used the HDMI input until today). How much would this cost me (or is there something I could replace or check myself for less money?)

Re: HDMI input failure

Hey guys, had the same problem. Found this solution on the web. Worked for me.


Turn the TV on, and enter the Service Menu. Select 2 for Self Check. Then turn the TV off, and after the fan turns off, unplug the power cord. Reconnect the power cord, turn the TV on, and the HDMI port is reenabled.

Here’s how to get to Service Menu:

Before entering the SERVICE MENU, confirm that the setting
of TV/CATV SW of the REMOTE CONTROL UNIT is at the
"TV" side and the setting of VCR/DVD SW of the REMOTE
CONTROL UNIT is at the "VCR" side. If the switches have not
been properly set, you cannot enter the SERVICE MENU.
1) Press [SLEEP TIMER] key and while the indication of
SLEEP TIMER 0 MIN is being displayed, press
[DISPLAY] key and [VIDEO STATUS] key (Fig.2)
2) The SERVICE MENU screen of Fig.1 is displayed.
3) Verify what to set in the SERVICE MENU, and set
whatever is necessary (Fig.1).
Refer to the SERVICE ADJUSTMENT for setting.
4) Press the [BACK] key to return the SERVICE MENU.

This should work.

Re: HDMI input failure

On JVC HD-ILA TVs the HDCP is triggered off by light.There is a light sensor behind the rear panel. If the rear panel is removed and the TV is powered on the sensor will lock out the HDCP of the HDMI signal. You all tried to do the reset procedure but you didn't say if the back panel was on or off. If you do the reset procedure with the back off it will just lock out again. Very strong sun light hitting the back of the TV will cause some light to get in thru the vents and trigger a lockout. An NG next to the IP is normal. All of the items listed on the two vertical columns need to say OK. If you reset the HDMI and you are still getting a green screen there is a possibility that the light sensor has failed thinking it is seeing light and causing the HDCP to stay locked out.
IF you get a black screen when you connect a known good HDMI signal this means that there in a compatability problem. A black screen means there is HDMI protocol communications going on but the signal can't be decoded.
It is the same thing if you pick up the phone and dial a number in Moscow, the phone there will ring and a Russian will answer it, So communications have been established but if you can't speak Russian and they can't speak English you don't have a picture.
Many people confuse a green screen and a black screen as being the same thing, They are not.
It would also be good if you give the exact model number since there are several generations of HD-ILA TVs now and the service menus differ a little.

I can't figure out how to program cable box. The cable is hooked up to the TV, but I can't find out how to get channels. Is there a certain menu or imput?

Are you getting any picture at all? check your tv's input button on the remote if your cable box is hooked up with hdmi select hdmi, if it is component video cable select component video, and if it uses a coaxial cable it should be something along the lines of tv. Push the input button on the remote to switch between the different modes

Picture in picture operation & connection to dvd player

Now--first--connect the DVR cable box HDMI output to the HDTV HDMI input (use the lowest numbered one e.g. HDMI 1) for this connection. Use a standard (not Monster brand) HDMI cable for this connection. Then turn on the TV, turn on the cable box and switch the TV to the HDMI input. A picture should come on. You may even hear the audio on the TV speakers. If so, that is OK.

Then--connect the component video output of the DVD HT to the TV component 1 input. Use a three wire component video cable with red, blue and green connectors on each end. Connect color to color on both ends. Then turn on the DVD, put a DVD in the player and start it running. Switch the TV to the component input and it should show a pix. The audio will come from the DVD player speakers.

If your DVD player does have an HDMI output, you can use it and just connect as above to the second TV HDMI input.

To get audio from the cable box out of the DVD player speakers, you will need to connect an audio cable from the cable box go the HT amplifier. Use a set of RCA patch cables and go from the analog audio output of the cable box to the rear panel audio inputs of the DVD player. The owners manual for this unit will give directions on using this input. Since your HT unit does not have any other inputs, you will not be able to get Dolby Digital audio.

Hope this gives you food for thought. If so, and you have more questions, just come back in with a follow up.

Good luck. Remember, the owners manuals all have hook up connections diagrams. Sometimes they will help.

The HDMI doesn't work properly


The resolution is only set by the sending unit, in your case the cable box. You need to change this to at least 720P something the your TV can handle.

Now once you have down this, to try and solve your HDMI problem I suggest you do the following.

Switch-off your cable box and the TV set, unhook the HDMI cable.

Now reinsert it carefully to make sure it connects properly on both sides.

Now first switch on your TV and set the input to Video 6 ( your HDMI channel )

Now wait for 30 secs. Switching on your cable box.

Do not press anything and check if your picture now stays on without shut-down.

if the menu and other startup screens on the cable box is not flickering, but the normal picture you might have a HDMI conflict with your TV set.

O, you cannot change the input types.

Hope this helps!

I just purchased a Sherwood RD 6513 reciever, I'm trying to connect a hd cable box (motorola dch 3200), dvd player (sony dvp ns710h) and a rca hd tv (l32hd41). I connected hdmi cords from both components...

Hi! I will be more than glad to assist you. I f you are going to hook up your cable box - motorola to the sherwood receiver, connect an hdmi cable to the back of the motorola cable box, there is only 1 hdmi output there, then connect the other end to the sherwood receiver on the hdmi input, then connect another hdmi cable to the hdmi output and the other end goes to your rca hd tv.

for the sony dvp, you have only one hdmi out, connect an hdmi cable to the back of the sony dvp if u have another spare. connect it to the hdmi input of the sherwood receiver. there is only 1 hdmi output at the sherwood, so u need to use a component cable to be connected at the back of the sherwood receiver component output then the other end goes to the component input of the hd tv.

if you dont have anymore hdmi cable to hook up your sony dvp, u can use component cable, the connection will goes like this, connect a component cable on the output of the sony dvp and the other end goes to the sherwood component input then connect another component cable to the component output of the sherwood and the other end goes to the rca hd tv on the component input.

I hope this will solve your concern, if you have any question, u can get in touch..

My HDMI set top box display reads "no input signal" but everything appears connected. I have no picture or sound. Cannot access any tv stations.

Make sure TV is set to HDMI channel.

Try a different HDMI port on back of TV.

Reset the cable/sat box and reset the TV by powering off both and unplugging them for the wall outlet for 30 seconds. Turn cable/sat box on first, and then TV after 30 secs.

If this fails, check the TV manufacturer's website to see if they have any software upgrades that will resolve the HDMI issue.

Go into the service menu using the remote (hit the sleep timer, then video status and display at the same time), go into the status menu #2, then power off the tv. This will reset the HDMI port. If your sitll experiencing the issue, probably a dead board.
