    There was a software problem for some non-compliant TVs, but Let's face it, they can't publicly announce that they have a hardware problem. This would give their competition ammunition against them. Not only that, but people that don't even use HDMI would want a new box before their warranty expires just in case they do need it some day.

    They already HAVE announced that there is a hardware problem.

    I think their answer is a bunch of bs. While it's true that HDMI connectors are a little flimsy, they don't get moved around much - if at all. I know my 622's haven't been moved around since I set them up. People have reported having their HDMI working fine for months and then suddenly cutting out. Something is flimsy, but I'd be more inclinded to believe it's their circuit board.

    Unless the air currents moving around the room cause the HDMI cables to wiggle, I just don't buy this excuse. If this were a general problem, then people would be reporting these problems left and right with their TV's, DVD's etc.

    HDMI connectors come in two types. The type that is on the cable and the type that is on the motherboard. I'll give you one more guess which connector E* is referring to. :)

    Personally I don't want to dismiss software problems 100%. Any time you have a problem that can be solved by unplugging and replugging a cable or turning off then on the TV set it is more than a hardware issue.

    I haven't been doing this that long, but I've never heard of anyone else's HDMI connectors failing. I'm sure the other five in my system have not had any problems. And I know mine didn't die when it was being moved; it died on an especially hot day.

    Anyway, it worked out for me in the end because I ended up needing the HDMI port on my TV for something else so I probably would have moved to component anyway. But it is irksome anyway.

    I have software rev. L3.65, with a Westinghouse LVM-42w2 HD Monitor... which kicked ass for the month the HDMI port worked. That was... ummm 6 months ago. They won't replace either my (purchased) 622 or 211 because software fixes should do the job. Well I've waited through 3 updates and nothing.

    They told me to take it to a Dish retailer and they could physically test the ports. How are they going to do this? I've gone through my process of elimination. I am nearing the end of my warranty.

    Is this an issue that could raise a class action suit?

    I'm a newbie here but having a problem that I seem to be reading a lot about right here.

    I have the VIP622 along with a Hitachi 60V500A. The Hitachi has worked flawlessly from the get go (2 years). I've had the VIP622 for about six months now and it too had worked flawlessly, at least up to now.

    Yea, my HDMI port went dead. Now all was working fine (even after the most recent software update telling me my HD was corrupt, which thank god I didn't believe so I re-booted and it worked not needing to format) even the HDMI port as I was receiving Hi Def. So the other night (3 days now) I switch over to Hi Def to watch a program and nothing. Dead, black screen. First thing I thought of was the TV, nope, not the TV after checking it. So I figured it's the VIP622. I did everything I read here, like switching from 1080i to 720p, etc, etc; all failing. I then decided to check all the cables as I've built up quite a system. All cables are in good working order. Still no Hi Def. So I decide to take a set of component RGB cables and try it. Sure enough it works.

    Now you can't tell me that it's a flimsy design and the HDMI's are breaking. Why would it work perfectly for six months then all of a sudden stop? If the HDMI port is not working why would the RGB composite work? Both should go down if they're on the same circuit. I can't say if it's software or not as I can't remember exactly when the newest software update was put on my 622 and when I last viewed Hi Def. But to just quit working is very odd.

    I'm thinking something is wrong on the software end of things, but then again is it possible for a HDMI port just to stop working? Has anyone else's HDMI port just quit working? Could it be hardware and if so should I ask for a new one?

    Thanks...!

    Welcome rcpilotjae,

    To answer your question, yes, this has happened to a number of users, in fact if you scan through all 8 pages of this thread and probably through other threads it's not all that uncommon for the HDMI problem to manifest itself this way. CSRs have indicated that this is a software problem to some users and a hardware problem to others. I'd suggest calling in and seeing what Dish has to say. If it doesn't get fixed in a software update before your warranty expires you may want to push for a replacement.

    Yes, my "HDMI" connector just failed after working fine for the last 7-8 months. I knew it was the physical connection because I could make the picture come and go by wiggling the cable at the back of the receiver. That worked for a few days and then it started failing regularly until wiggling the cable no longer restored the picture. The Dish CSR tried to go down the software/tv compatability path until I told them abut wiggling the cable. I also have another 622 and a 942 and I swapped my Sony for my Samsung (which works w/ both my 942 and my other 622) and I still had no picture. This was last Monday. I received my replacement 622 a few days later. The new one works perfectly.

    In my original post I wrote that dish called it a software issue. As of this writing it has been 8 months and I am still reading reports of the VIP 622 hdmi output not working and dish saying it is a "software issue". I wish you the best of luck in resolving this issue. Wouldn't it be nice if dish read this forum? Or do they?

    Thanks for the replies guys. I'm at a loss here. First, no wiggling issues, so that leaves the broken HDMI connector OK in that respect. After 6 months (or more) it just stopped working. That's very odd considering the unit has had no problems from the start. (Must have gotten lucky for once! :lol: )

    The HD is working with the RGB composite cables but I can see a noticeable decline in picture quality. The HDMI port was much better. I haven't called Dish yet for fear of getting a story told to me. But will do so next week just to hear the response. Who knows? Maybe they'll just send me a new one. :eek2:

    I'm not an electrical engineer, but it seems to me if the HDMI port goes dead, so would part of the RGB ports. Unless they're totally separated circuits, which I doubt. (But could be wrong.) What I'm saying is one port shouldn't work unless the other works too. Some where along the line both ports should go out.

    I'll let you know what Dish has to say. All I want is my HDMI port working again.

    I could be wrong here...and those more experienced, please tell me. But it seems as though there is the possibility of the HDMI port being located to the area in the box that may cause the most heat? I mean something failing one day after months of working just seems to be heat related to me. And it makes some sense especially hearing about the "wiggling" issue. The solder points could be done very poorly (come on now its probably done in Mexico - no offense to anyone), and the heat is enough to weaken the connections.

    Just my two cents.

    Two things to check. First, did you mean component or composite? Composite is not HD.

    Second, your TV probably lets you calibrate each port differently. Did you set the component port to the same settings the HDMI port was set to? That can make a big difference in PQ.

    I believe for most people component can give PQ just as good as HDMI if they take the time to set it up right. Far preferable to swapping out your 622 every few months (and losing all your programming and timers). But there's probably some TVs where that's just not true.

    Just cause wiggling doesn't make a difference doesn't mean it's not the connector. You should really reread all the threads. I tend to post more at the "other" forum because I'm turned off by the AVS censoring of links to other places (or I'd provide some links).

    This is a VERY common failure. I had an HDMI port that failed after months of working. Since Dish was spewing the Software story and refusing to repair, I was forced to open it up. One pin of the connector was no longer soldered to the circuit board.

    I resoldered the pin (VERY tricky for the unexperienced) and the HDMI has been working since.
    Of course they are separate circuits (I am an Electrical Engineer) and obviously separate connectors (which is where the failure is). Since the component is coming off a Digital to Ananlog converter and the HDMI is not.

    Also, HDMI is probably fed through an extra i.c. to provide the HDCP enctyption (not on Component).

    Again, this has been discussed it great detail at the other forum.

    The problem is not the soldering, it's the design. This is a surface mount connector. This type of connection CANNOT tolerate stress. If the solder points do not break, any stress will pull of the PADS (connection points) off the surface of the PCB (realize these are on top not through the board).

    Soldering the connector to the PCB then screwing the connector to the chassis is putting way too much stress on the solder points (the back of the 622 is pulling the connector away from the pcb).

    Combine that with the movement from (even minor) thermal stress (chassis and PCB don't expand/contract at same thermal rate), and eventually the solder points break loose.

    After the repair (around 6 months ago), I loosened the hdmi/chassis mounting screws on both my 622s. No failures since. BUT I have to be VERY careful of cable movement/hanging since the port is no longer supported by the chassis.

    I don't recommend this unless you want to risk your warrenty, but my actions support my theory.

    AVITWeb:

    I don't think you're too far off here. With the stress and heat combined on the HDMI connector I can easily see where the solder joints can pop off.

    Hunter Green:

    Yes, I meant, component. A slip of the keyboard. (Actually my old mind that doesn't function as well as it once did.) But as they say, learn something new everyday. I did not know the ports could be calibrated. Is this part of the internal color adjustments (the ones most folks would have a pro come in and set)? I haven't seen anything like this with my set, but then again there's a lot of adjustment features I haven't messed around with (yet). The HDMI output was definitely clearer or sharper than the component RGB. And if I could set it up to be almost as good as the HDMI port, well, two ports are better than one.....

    David_Levin:

    Thank you for that reply. While not an engineer, I'm not a total novice to electronics and you made perfect sense to me, with a perfect answer. Now I realise the two circuits are totally different. (Some thing I should have thought of myself, but my mind seems to be in other places when I need it the most...LOL). In fact I'm experienced enough to re-solder a surface mount connector with no problem and have the fine tools and solder pencil to do it. At this point it would be less hassle for me to open the unit and see if in fact it is just a lose or broken solder joint. This seems to be the most logical failure point to me. I just don't believe in the software theory.

    Doing the check to see if it's just a failed solder joint is a far better method than having to replace the unit every six months or so. Since I've gotten one that seems to work flawlessly (other than this problem) I'd be more inclined to keep it rather than get a refurbished unit from Dish.

    I don't know how your TV works, but most if not all HD sets have some means to calibrate colors and settings for ideal PQ, and generally allow you to use different settings on each port. Calibration is best done using a DVD or test patterns designed for the purpose.

    You'll find that the default settings are actually pretty bad on most TVs, partially because of odd historical things (like cranking up Sharpness, a setting which has outlived its purpose) and in an attempt to make the TV look good in the store, not your living room.
