So.... can someone explain the Why's and Why Not's.. of connecting these JVC D-ILA TV's to a PC, a HDTPC?????
I would assume that because the TV is probally set up to mate with a input that has the copyright BS in the stream?? that this is why a PC /HDTPC with the DVI (HDMI?) output will not work right?
Why do they say in the manual these Tv's will not work with a PC?
Sort of sad, seeing how this is 2005...
Have the 61z575... would like to build a HDTPC...
Anyone? |

WeAreNotAlone69,
I have an HTPC connected to my HD-52G786 and it works great. I have an ATI Radeon-based video card and am connecting from the card's DVI output to the JVC's component inputs via an ATI "DVI-to-HDTV Adapter" (http://shop.ati.com/product.asp?sku=2537967). The ATI CATALYST drivers allow for resolution tweaking to mitigate the screen clipping due to overscan....no need for Powerstrip. I don't mean to be a shill for ATI, but it has worked for me. Also, I HIGHLY recommend TheaterTek DVD software for playing DVDs and video files....the picture quality is outstanding on my setup. |

WeAreNotAlone69 .... followup,
It just occurred to me that there ARE copyright issues with outputting high resolution DVD video to an external TV display, but you can get around this with the DVD Region Free utility (or similar).

For PC hookup thought the HDMI input, you need a videocard with HDCP compliant DVI output.
A lot of the newer ATI videocards with DVI out are HDCP compliant, which is what the JVCs HDMI inputs needs to work. Without that HDCP "handshake" you get a blank screen. |

Bobo,
Picked up what looks like an older ATI card, there is a chip on the backside marked ATI RAGE Theater...(chip on second picture below near DVI output) Card has a COMPAQ part number on it. Appears to be new as there is no dust on fan.
Since it is probably NOT one of the newer cards that adapter sounds interesting...
Looks like I need to hunt around on the ATI website.. see what it is... see if the drivers will support the card. Have the card, a breakout box, a usb remote pickup, a ATI remote, a DVI cable, S-Video cable.... Got a good deal on it, so maybe it could be used for something (if not for the JVC)..
PS: Thanks for responding, and the info /tips!
I hope the people in Hollywood would drop off the face of the planet... More copyright stuff..
BTW: Have a SAMSUNG SIR-T451 HD-TUNER.... About 10 months old.. Anyone have an info on that unit, know where to get a SERVICE MANUAL.. or better yet know how to get into SERVICE MODE so maybe the overscan can be adjusted???? The modes on it really suck.. Had a Motorola tuner that did an excellent job of stretching. shrinking content... The Samsung is brain dead, you have to manually switch the modes... and the modes are WAY off.. Looks like crap.
Posted here, and have not gotten a single response?????? :-(

Just purchased the 52" D-ILA (575) for a good deal.
First question: A lot of QC issues with this model vs. the newer models?
Also browsing through this thread I saw a reference that Mr. Lynch posted his picture settings but could not find them.
If you could re-post them and save me hours of staring blankly at the Avia test screens I'd appreciate it. |

My settings after my set was calibrated by my ISF friend. The biggest changes he made where in the color drive values in the service menu. You should have something similar. The Green drive usually comes from the factory a little "hot" and might need to be lowered a bit.
These are the same document, just different formats..

Kano-
QC issues were mainly with the first batch of sets manufactured (May 04-August 04). The worst of these had an HD-DILA sticker on the upper left on the TV (Pre July sets). They made quite a few "upgrades" with the 2nd batch of sets and they have been very reliable. My August 04 set had some early issues that were quickly taken care of and it has performed flawless ever since. I would purchase the same model again in a heartbeat. I love my HD-52z585. |

Okay... it's almost time to buy!!! I had been waiting to get closer to my date to move in to my new home... but the wait has been of great benefit. The prices have dropped again!!!!
Here is a question for you guys who have satelite TV...
I have heard and read that I may not need to upgrade to a HD satelite receiver yet because there are still many programs that I watch that are not in HD, and I am receiviving a digital signal anyway. So I am thinking about getting the DIRECTV DVR.
Should this be good enough until more programming that I watch are broadcast in HD?? |

Purchased an HDMI cable today to use with my Denon DVD2910.
First impressions are it looks less digital, especially the edges. The 2910 has a black level enhancer that is a good bonus through the HDMI only.
Through component the picture is almost too much... if that makes any sense. |

Okay, I've skimmed through this post a little. I just made a post for myself, as I'm overwhelmed with how many are on this one. But one thing I seem to see is that people are asking for the service manual alot. Why is that? And could I get one, as I'd like to see what I can do to it within reason... esheldon76@gmail.com . Thank you, and thanks in advance for anyone who helps me in my post. |

Have followed this thread off and on for a bit. Bought an HD-52Z585 AA in May. Last week the picture went to heck. Three images, each a different color. Called closest Factory Service Center - outside their service zone. Had to call JVC, wait a week for response. JVC finally contacted with a request to send pics of the issue. Sent the pics and got fast response that Service Provider had "agreed" to service my machine. Now scheduled for 22nd. Initial failure was on the 3rd.
Diagnosis from pics is "Optical Drive replacement" per JVC. Any clues on what that means?
If anyone is interested I can try to post the pics I sent them.
Thanks for all contributors input, this forum is why I chose this machine over other candidates.
Note for Mr. Lynch, I would appreciate receiving a copy of the manual, thanks for your contributions. Please take the TRASH OUT of the embedded email address. Sorry for the hassle but it helps reduce the volume of spam. |

"Optical Drive replacement" is also know as a light engine swap. It is a $1200 part and should take less than an hour to do. They open up the back and slide the entire chassis out. I had the swap done after a few months of ownership and it has been perfect since then.
I didn't see an email address posted. You can just send me a Private message if you don't want to post it. |

Hi,
I've had the 52" for about 6 months now and it's been great. I started with DVD/movies with my Toshiba/HDMI and just yesterday, got setup with OTA HD and watched the seasoner between Pats/Raiders. Just an amazing experience!!
Now that I'm completed hooked on HD - I am looking for a HD set for my bedroom. I really want to move the 52" to my bedroom and get the 61" since I am really really happy with JVC. However the 52" would be a tad overwhelming for my bedroom and since JVC doesn't have anything smaller - my question to you all is: What would you recommend for say between 40-50". Given it's in the bedroom, I would bias function (as in PQ, reliability, price, etc) over form (flat, sleek, etc)
Thanks in advance for the advice. |

As per TvShopper posted above in response to my question on the same subject:
"I have done a focus of my JVC. It's not hard to do. You need to remove both the left and right speaker grills. Then you remove the front plate on the TV to access the focus lever area. You loosen the focus lever using a hex wrench and then slide the lever left to right to focus. Once you have it completed, tighten the hex nut and reassemble" |

we are not alone,
do you do this with the power on or off? how many screws, its just one for the grills. but there are quite a few more behind those front plates, the center panel is attached by a cable. do you remove that panel? or am i overlooking something? |

Scott,
I haven't done it myself yet... But I would assume once you get access to the focus adjustment screw....
You're going to have to have th TV turned ON... to be able to SEE the picture :-)
On all the CRT based sets I'v done... I've always had to have the set turned ON to see the display. |

Scott,
I'm wondering "how" the three chips are adjusted during assembly.
Went into the service menu to adjust the convergence... One of the colors being slightly off. (Will not adjust, so I assume the static adjustment is off slighty.)
BTW: Would have been "nice" if they would have put the convergence menu in the regular user menu.
Not much that a user could "screw-up"... as it's not a very "involved" process. |

So I see we have a nice thread going on here.. I feel at home here already..lol. Let me start by giving you my info..I have the july 2004 build HD-ILA w/ out the sticker at the top. Up close (12" away) I have not identified any dead pixels. So far no light leakage either screen is uniform around corners and edges.. So what's my problem...No HDMI input I get only black screens. Will not work with two devices using two different DVI to HDMI adapter cables and still a no go.. Screen is BLACK. I have a zenith 318 DVD player and a dish network 811 receiver. Set devices to 480p 720p 1080i. What is strange is in the manual it says the output of signal must be 480p for digital-in to work. I just want the HDMI to work. My next question.. I would like anyone who has had the recall taken care (the ballast/poor solder) of express there experience...was it worth it, was it an easy in home job, or did really need to be a in shop repair. I don't want to let this out of my home.
And last this is for Mr. Lynch would it be too much trouble to email me a copy of that service manual. It would be greatly appreciated Suzukimandw@allvantage.com

I would add to the above:
It would be NICE is someone could post PICTURES of the poor ballast solders.
Most of the time it's a simple fix to re-flow them.
I too am of the mindset of NOT letting the set out of my house (or letting the local "techs" touch the set)
Frank,
Are your devices HDCP compliant thru the DVI outputs?.
Without the HDCP "handshake" you get a blank screen |

WeAreNotAlone69, Yes my Zenith 318 and the dish network 811 are both HDCP compliant. Again I read in the manual that the source needs to be 480p for digital in to work. Well it does recognise it when I set the source to that resolution all I see is black screen. But then I read lots of people dumping a 720p and even 1080i signal into the HDMI and they get it to work...hu? Mine won't even see the source unless she's a 480p nothing more nothing less. |

Ok, I did a self check and the HDMI says NG1 Should it say "OK" or no? The RGB says NG9. Don't know what this means until I take a look at the service manual. I'm techinical savy so don't worry I won't screw it up. Heck after the warranty is up I just might open this sucker up and resolder that poor ballast conection if need be..lol. I can solder very well. Any info would be greatly appreciated. |

Frank,
The recall part is covered even if your warranty has expired. Just like with a car. Not all the sets that need the part replacement have a bad solder. There is just a potential for it. When I had mine replaced I watched the entire proceedure. There is not much to see. It is a small black box that has a wire clip, and 2 screws. The problem is inside the small black box. Pix would not show much.
Anytime the set experiences anything "odd", you will get an NG in the self check. It is very normal. The HDMI looks for a HDCP compliant device, and when one is not detected the first try you can get an NG. The RGB has alot to do with your signal, so any signal issue, may also trigger an NG. It is nothing to worry about unless your picture is messed up.
On the original batch of JVCs had some issues with the HDMI not working properly. Mine accepts a video signal, but no audio. I never got it fixed because it is not a big deal . My audio runs to a reciever so no TV sound is needed. I can also just hook up a set of RCA cables if I did need TV sound when using the HDMI input. |

Hey Mr. Lynch on the HDMI out of the Denon DVD2910 I can either pick HDMI Y Cb Cr or HDMI R G B. The manual doesn't explain the difference, both look very similar... any idea? |

Mr. Lynch I still wonder why it will only make the HDCP handshake if the signal is a 480p.. anything else, and the digital-in wont even be on, as seen when you go into the menu and try to select size 1 or 2. None the less, it can see the 480p signal but all I get is a black screen. I wonder if the dvi to HDMI cable can't make the handshke correctly..
And, on another note if this tv is native at 720p does that mean that 1080i as advertised is not the correct resolution of the set. I guess what I'm saying is it possible for this set to display 1080i through component cables? |

Kano-
You should use HDMI Y Cb Cr. It will allow the full 10 bit processing to go to the TV. Video should look slightly better. Less color banding and smoother edges. HDMI RGB is limited to 8 bit processing, and should only be used if your TV/Monitor does not support the HDMI Y Cb Cr.
Frank-
My HDMi input accects 480p, 720p and 1080i. I'm not sure why your's will not. I do know that 480p does not require the HDCP handshake like the HD resolutions do, so it must be an issue with the HDCP.
The JVC ACCEPTS a 480i, 480p, 720p and 1080i signal. It converts everything to it's native resolution of 1280x720. Basically 720p. A 1080i signal will be scaled down to 720p, but it looks almost exactly the same as a native 720p signal. Either way it looks damn good.
If your curious about the difference between 720p and 1080i, or think your missing out on something read this...

My JVC 52Z575 was manufactured in August 2004. JVC has determined that the light engine needed replacement but, because there's a three week wait for that part they're going to replace the whole chassis. I'm really pleased with their service. Anyway, my question is: Is there any way to determine the manufacture date of the chassis, e.g. serial number? And if so, how do you make such a determination? |

Frank,
I don't think there is a date or anything on them. The older light engine has a foil tape shielding, where as the updated version has an aluminum housing. When they do the swap, you can easily see the difference. After the swap, your setting will still be the same, but you will need to recallibrate it using AVIA or DVE. My original light engine had brightness settings of +5 and higher, the new light engine numbers are now all negative. The new version is a much brighter and efficent engine. With lower brightness levels, the black levels increase too. You should be very happy. |

Okay.... I did it last night... the 52G886 for $1799 + $249 shipping. I got it from Abe's of Maine and it should be here by next friday or that following Monday!!! I went on and ordered the HD receiver package from DirecTV too. I am extremely excited, but I am also a little concerned, because I am not half as tech savvy as some of you on here. I am concerned that I won't be able to do the configurations I read about, or get the video input set up correctly. I will have two video sources for the JVC (satelite and DVD) I assume that I will have to use the component cables for the DVD(no HDMI output) and HDMI for the satelite HD receiver.
Any thoughts??? |
