HDMI ports not working - Blu-ray Forum

acme3dmax · 08-01-2009, 11:45 PM

a friend of mine had this happen to him and i wanted to see if anyone else has had the same thing happen to them.

here is what he has:

samsung HDTV
Onkyo 606
ps3
digital cable box

he had everything hooked up by HDMI cables. one day he came home wanted to watch TV but he could not get any signal. he tried the ps3 and got nothing. he hooked up the cable box directly to the TV through HDMI and got nothing. same thing with the ps3. he hooked up the cable from the wall with coax with no box and got a signal. he got a replacement cable box and hooked it up directly to the TV through HDMI and that worked.

so from all that it looks like the HDMI ports in the ps3, cable box and at least the inputs to the onkyo are dead. i don't know much about onkyo but he was saying you can reassign the HDMI ports to different functions and he went through and reassigned and tested all the inputs and none of them worked.

has anyone heard of this before? seemed kind of strange problem to get. is there anything that can be done? he is going to check the warrenties but he could not remember if it had been over a year ago since he bought them. he said that he might get component cables and opical audio and use them.

It is unlikely that this can be fixed easily. Most likely all interfaces would need repair. Did anyone messed around with HDMI cables while they are active. That can potentially damage the HDMI interfaces.

acme3dmax · 08-02-2009, 04:14 PM

no he has it in a cabinet and nobody else would have been messing with it after it was hooked up. i've heard the onkyos run pretty hot, whould the heat have cause it? he has the ps3 and the onkyo together in part of the cabinet but the cable box was in another part of cabinet seperate from the other two.

syncguy · 08-02-2009, 11:58 PM

There is a possibility that excessive heat could cause HDMI malfunction. If Onkyo short circuit data and power rails of its HDMI interface, that will cause all other interfaces connected to it fail.

IMO, HDMI is not a very good engineering design since it has power and data rails close and spacing is narrow. This could easily cause power rails to touch data rails and could fry interface circuitry. Power related issue in one unit could cause all other interfaces to fail as well.

People should not plug/unplug HDMI cable while active if they wish to ensure health of their HDMI interfaces. Switch off all connected units before connecting/disconnecting HDMI cables.

yes this has happenned to me and i have yet to take it for inspection to see what caused it and how to avoid it again it happenned with only 1 hdmi port on onkyo 705 so im down from 3 to 2 plus the 1 out of course

I had that happen with the Pioneer Elite 92 receiver I purchased about 1yr ago. I had the receiver in a rack setting and the HDMI inputs/outputs suddenly stopped working. After switching out some cables, I realized only the component conections would work. Took unit in for repair, (Elite products have a two year warranty), and the Pioneer authorized repair facility called today to say it is ready to be picked up.

I asked about the problem and they said they had to replace a HDMI board, but everything is now working and they checked out the entire unit.

Thanks goodness for the warranty!!

This is funny because I googled this issue and it took me right to this thread.
My Pioneer Elite 92 HDMI ports just crapped out on me too. I can't get any handshake with my Direct HD DVR, Pioneer Blu-ray player or HD DVD player. Nothing. I was watching a recording on my DVR, left the room thinking it was end of the show I was watching and I saw a blank screen. So it crapped out right in the middle of it being on. Tried resetting DVR, unplugging cables, etc.
I guess I have to check to see if my warranty is still in effect because I'm not quite sure I have owned it for 2 years.

I found about my HDMI ports not working when I went to watch a movie and I couldn't see/hear sound/picture. I then connected the component outlets as a test and they worked, so I knew there was a problem with the HDMI ports.

All Pioneer Elite receivers come with a 2yr warranty, so you really need to look for your receipt, as I had mine repaired, no questions asked. Picking up my 92 from the shop tomorrow. Hope everything works out for you.

It appears that many people had problems with HDMI which required repair, i.e. $$ ifIt appears that many people had problems with HDMI which required repair, i.e. $$ if warranty cover is not available. This is a significant issue for everyone.

If the cable is wiggled when connecting or disconnecting while active, it is easy for power rails to touch data rails causing instant failure. I think it is a design problem with HDMI that we have to live with. This is in contrast to the robust USB interface. Hence everyone should be cautious when handling HDMI. The best method is to power down all units prior to connecting/disconnecting HDMI cables.

I think this thread or the information given in this thread should be in the sticky area so that many people could avoid potential damage to HDMI interfaces.

I'm picking up my Elite 92 this Sat, and will ask the repair facility about ways HDMI can be damaged, and if there is a reoccuring problem with HDMI repairs. Once I pick up the unit, I will be able to see what had to be repaired/replaced in order to fix the HDMI inputs/outputs. Will post info this weekend.

Thanks, This will be useful information.

I had an issue with HDMI on my Panny Plasma. It just stopped working one day. I tried everything and found the culprit (TV - HDMI 1 connection) via a process of elimination. The HDMI 2 connection worked fine. I wasn't happy with this however, and since my TV was still under warranty I was able to return it and get another (newer model) TV. Haven't had any problem since.

HDMI must be very sensitive as I`ve heard and read about problems with this connection several times. Kinda makes you wonder how stable it is.

I think it is a HDMI design problem. The pin spacing is too narrow and it is very easy for the rails to touch each other if wiggled while connecting/disconnecting.

Thank God I don't do much of that. I do it about once a month...want to get behind my setup just to make sure everything remains seated just so. Plus I can clean the dust-bunnies off! LOL

Not to worry. If you do your cleaning while the system is off you are okay - no problems.

HD Man · 08-09-2009, 06:38 PM

Ok, I picked up my Pioneer Elite 92 receiver from the authorized repair facility and here is the work they had to do to repair the HDMI ports:

1) Replaced HDMI board assembly
2) Reseated connections
3) Rechecked bias and voltages
4) Completed load test

They also told me to be thankful it was covered under warranty, although he wasn't sure of the retail cost of repairs. He also said that before your change any HDMI connections, make sure you power down your equipment before changing/making connections. Said they have seen instances where customers have damaged boards while changing connections when equipment is turned on.

Everything working great now!!

This is what I have indicated (with reasons) in my previous posts and requested Mods to add a link to this thread in HDMI sticky post.

For the record, IEEE1394/Firewire cable has a similar problem and should not connect/disconnect while active.

I recently purchased a Pioneer Elite 151 Plasma TV but had to have it replaced because the side HDMI hook-up wasn't working properly. It caused the picture from the Blu-Ray player to break-up (pixelize) in a small area on the screen (which usually was moving). The problem was not random but consistent to a particular point on a DVD. For example, in Gran Torino, when Clint Eastwood walked outside from his house and turned towards his neighbor's house, his head would pixelize a bit. No matter how much I replayed that scene, the picture would break up at the same spot. This happened on all the movies I watched.

I tried playing a different BR player, different HDMI cable and got the same results. I tried playing the BR disc upstairs on a different HD TV and there was no problem. That's when I knew it was the Pioneer TV. Hooking up to a different HDMI jack on the back of the plasma TV worked fine. So I had the electronic store send out a new Pioneer.

The side HDMI jack worked fine and Clint's head didn't pixelize! So the crew left and I was happy..............for a short while. Later on during the day, I decided to hook the HDMI cable to the back of the TV. With everything turned off, I switched out the cable.

The pixelization was back and in the exact same spot. I tried the other BR movies that had similar problems and all of them broke up in the exact points of the scenes previously experienced on the first TV.

Has anyone else experienced the same problem?

As of this date, I am waiting for the electronic store to get back with me. They are waiting to hear from a Pioneer rep. I don't want to keep swapping out Pioneer Elite TV's.................even though they have 50 more in their warehouse to choose from......
