Bad HDMI Connection? - JVC Service?

[Pitzy]

Has anyone heard of or ran into a problem with their HDTV when they connected the HDMI connection? When this is done, the left hand side of the screen has black horizontal lines of interference that comes in and out. I have tried multiple cables, as well as multiple HDTV receivers. The model I have is 61Z786 and the receiver is Dish Network 811. This TV model only has a digital input of HDMI and the receiver only has a DVI. I have used a HDMI-DVI cable and also used a DVI cable with an HDMI adapter. Neither of these worked. When I use component video, it works and I do not have the interference at all. Something obviously isn't working and I would have to say it is with the TV and the HDMI input. Does anyone have any ideas or suggestions?

Also, I bought this TV online and am under warranty and dealing with JVC for support. The closest authorized dealer is over 2 hours away. I called them and they don't come this far, so I doubt anyone else would. If JVC doesn't give them special authorization to come this far, what do they typically do? Would they send me a new TV for an exchange? Would they make me ship it to them until it is fixed? Does anyone have experience being in a similar situation?

Thanks, and all responses are greatly appreciated.

Well... you say you've tried difference receivers with same results. So, I'd tend to agree that the TV/input is suspect.

IMO.. the only way to be sure is to connect another DVI device (DVD player?) and see if the same symptom occurs.

Also... have you verified that the 811 settings are correct?
Have you tried changing output resolutions on the 811 (480P, 720p, 1080i) just for experimentation?

Just in case... check the return policy from where you purchased the set.

I have changed the settings of the 811 between 1080 and 720. It appears to be worse on 1080, but is still a problem on 720. I don't have another device with a HDMI or DVI connection. I have thought about "buying" a DVD player and testing out the connection and then returning it, but I can't justify keeping a HD - DVD player when my TV only has 1 digital input and I have a good DVD player already.

Do they make adapters that allow multiple connections to 1 HDMI input. That way I could connect my HD receiver and a HD DVD player to it without having to switch between them every time. Also, is it worth getting a HD DVD player when I have a good Progressive Scan DVD player and use component video?

Gefen Video Switch will switch multi HDMI but not cheap. Heard lots of issues with compatibility on HDMI (as well as DVI). Can you find anyone with 811 and JVC working on HDMI?? Even if a HDMI DVD player works with the JVC it won't really prove anything (BTW the all digital DVD players look great). The 811 could work with another TV.

I would persue JVC and Dish Network since they are in the best position to have more information and hopefully answers.

Pitzy,

It's been 26 days since you posted..... What was the "fix".


PS: In cases where their "prefered" service shop is two hours away I think they can authorize a local shop to do repairs. I had an extended warranty on another item I had and was very unhappy with the work that mfg's prefered shop did.. and they authorized another shop. That was thru the warranty co, so JVC polices may be differant.

Sorry for not getting back to you sooner, but the service shop just came to my house to fix it this week. JVC sent them a HDMI board as that is what their over the phone diagnosis was. It was installed and from the brief time I had to watch it (20 minutes) I have not seen any issues. However, the audio, while connected to the Digital In analog inputs, cuts in and out. This issue existed before and I thought it was related to the video issue I was having. Therefore, there are still a few outstanding questions that remain. Did the new HDMI board fix the video issue and I just didn't notice it in the brief time I had to look it over? Is there still an issue with the HDMI if the audio is bad? The analog shouldn't have any relation to the HDMI board, but maybe there is a software problem for the Digital In mode? Or, was there never a problem with the TV and it has to do with compatibility issues between the receiver and TV?

Does anyone know if there are compatibility issues with Dish Network 811 and JVC DILA? I have tried multiple receivers, so it most likely isn't an individual receiver issue, but maybe those two models don't work together for the DVI/HDMI connections. That may explain why the audio and video are bad? As of now, if I had to guess, I would say it is something with the TV's Digital In mode.

My next steps are connecting another audio source to the Digital In analog connection to see if the sound cuts in and out. I may also purchase a HD DVD player to see if the Digital In works with that.

Working with JVC Customer Service/Field Support has been extremely painful. I have direct numbers to 4 or 5 service technicials and managers. I leave messages on their machines and I get no response. The only way I have found that works is when I get a number to someone new in a more authoritative position, but I think I have run out of options at this office (New Jersey).

This TV has a beautiful picture through component cables, but when you spend $3,000, you would want everything to work and that perfect experience to be there as well. However, this hasn't been of that nature.

JVC did end up authorizing someone to come from 1.5 hrs away. They didn't like it and cut off all communication with me. It has been 8 + weeks and I am still not a satisfied customer. If it is the Dish Network Receiver issue, they should know that and the diagnosis for those issues. I will never buy another JVC product in the future....not because of their products, but because of their horrible service.

i am also having trouble with my jvc hd56g786 d-ila tv. my problem is i have green screen with horizontal lines my audio is ok. so far. i have had the set for only three days directv set up a new hdmi rec. for me that was the first time tv had been turned on i first had screen problems about 6 hours after i had used it, the tv would pop green screen would come on for a few seconds and then it finally quit. i had directv come and make sure rec was not the problem. then i started calling jvc support which is a nightmare. my local jvc dealer is only 35 miles away but he refused to come, he stated that jvc does not pay him enough to cover costs of the trip. i spent all day on the phone with them just as you have and still no results. jvc tech support is a poor excuse for consumer relations. i will never buy another jvc product again because of this. i had tv connected to hdmi connections. direct tv guy even changed and tried component cables still same result . also my dvd player when activated gets the same green screen. i am totally upset over this, does anyone have any ideas what would cause this? i purchased my tv online thru beach camera stores and that is the only positive experience i have had with jvc product. i ordered it on sept 18 could i possibly have vredit card company to hold payment until this is corrected. any info would be helpful. i have posted on other forums and asked people to post on my thread about customer service issues from jvc i think we should do it here. as indivduals they want pay attention to our problems but if enough jvc owners who are having support problems join forces they may be forced to listen because of negative publicity. also if any of your local tv stations have a problem solver segment talk to them, i bet you will get service if jvc has to start answering questions about thier support. i am on the east coast , jvc headquarters is in new jersey, i have ttelephone number of consumer affairs if anyone needs it. i called them and was put on voice mail by four different people, they must have been out golfing.

thanks for any reply on these issues - please email me if you want to

Wish I was here about a year ago, but I didn't have my JVC HDTV then. I do now and for the last few months have also had issues with the HDMI input. I have a DVR set-top and shortly after installing HDMI cables, a message kept appearing about unauthorized HDMI output/copy protection mode and the picture would dissappear. The TV works fine with component video cables. I think it's a combination of the monitor's firmware and the HDMI board itself. Funny thing, I recently reinstalled the HDMI cables, two months after the problem first cropped up and the TV's working fine now.
