Sony Projector HDMI failures - help!


Recommended Posts

I'd be grateful for any tech input on a frustrating issue.

 

In mid 2019, I had a projector and screen installed as described in this thread:

 

The projector is a Sony VPLVW570ES and this receives it's signal from a Bluestream HDMI switch via a 20 metre fibre-optic HDMI 2.0 cable.

 

A few days after the initial installation the projector stopped working.  Both HDMI inputs had failed and the projector was swapped out for a new one.

 

For various reasons, the projector has had little use since then, maybe a couple of hundred hours.  It was working fine when it was last used a few weeks ago.....................

 

.......................................until last night!  I turned it on and there was no signal on HDMI 1.  I swapped to HDMI 2 and that input still works, but HDMI 1 has clearly become U/S between when I last turned it off several weeks ago and last night. 

 

I would simply put this down to component failure, except for the fact that two HDMI ports failed in the originally-supplied unit in the days after installation and now another has failed.  Given HDMI failure doesn't seem to be a common problem with this unit, it seems difficult to put it down to co-incidence.  But I can't see how it's anything else.

 

In both cases, the HDMI port failure has been confirmed by using another DVD player and HDMI cable connected directly.

 

Of course, I'll go back to the vendor who I believe will provide excellent service and the Sony should be covered by a 3 year warranty.  But I thought I would post it here in case someone more knowledgeable than me has any ideas on what could be causing this.  I also wonder if I should expect replacement or repair?

Any chance your using a "Ruipro" Fibre Optic Cable ?

I'm pretty sure it's a FIBBR cable.

 

But I'm curious why you ask that.  Can a cable kill HDMI ports?

Could be a power on sequencing issue. HDMI ports can be killed by changing cables when the device is live. Just a thought.

There was no cable changing involved - the HDMI cable was in HDMI 1 port and it worked when I turned it off, but not when I turned it on a few weeks later.  In any case, I read somewhere that current HDMI standards allow for hot swapping - or something along those lines.  But the fact that both HDMI ports failed in the first unit would totally deter me from doing that.  BTW, there was no hot swapping involved in the original failure either.

 

I've ruled out power on sequencing issues by

  • turning everything off and on again several times
  • noting HDMI 2 still works fine
  • trying another dvd player and cable into HDMI 1 and 2  - HDMI 1 is dead and HDMI2 works fine.

But thanks for the thoughts - any and all ideas are welcome as I'm at a loss.  Currently I'm leaning towards the idea of coincidence or a bad batch of HDMI ports.  But, if that was the case, I'd expect to see others with the same issue on the net.

Tony I had issues with a Fibbr HDMI cable and from the Apple Set top box.

I found there were mainly issues on the No.2 input on my Epson projector , such as not recognizing HDR and ended up going to pretty well stock HDMI cables .

These problems can drive you crazy, but don't mix Fibre with standard in any part of the chain - remember @betty booptaught me that! 😉

Thanks Evil

 

But this isn't non-recognition - it's dead HDMI ports X 3 in total so far.  In yours or Al's experience, did the fibre cause any permanent hardware damage?

 

This cable runs through the roof structure and  would be an absolute PITA to replace with something else.  I'd have to be really sure it's the culprit or that it was definitely causing other issues to warrant drastic action.

Have you had thunderstorms close by when the ports failed? I've had a couple of HDMI ports fried when connected to longer HDMI cables - presumably from induced currents from nearby lightning strikes.

I guess that has to be a possibility.  The interval between working and not working was several weeks and there were probably one or two storms in the intervening period.  But nothing else has been affected in any way and nothing would have been turned on during a storm.  In fact, if I expect thunder and lightening I typically disconnect everything in the shed from power and internet connections.

 

And inuitively I'd have thought a fibre HDMI cable would be less likely to be affected??

Fibre cables still have some copper strands for the less data intensive functions - if I recall correctly CEC, EDID and power. Induced currents can be developed in the cable itself, not from power or network connections.

Well, I guess it's a possibility and I'll add the HDMI cable to the "unplug list" when anticipating storms in the future.

 

But I don't think that possibility removes any warranty liability and it suggests HDMI ports are extremely fragile.

Agree it's a legitimate warranty claim regardless. HDMI ports should be robust and reliable (even if that means the industry specs need updating).

There were some reports and concerns in the US that some of the Ruipro cables were "killing" HDMI ports on the new NX series projectors.

 

Yes , an active cable can damage a HDMI port due to overvoltage.

Just speculating that its to do with the 5v voltage being supplied over such a long distance .  That is assuming you have a copper based hdmi cable going into the switching bluestream [and the ruipro afterwards ]

 

Ruipro need less voltage than active copper so longer runs are feasible . Depending on what hdmi you have you may need some stabilisation ; cypress are worth enquiring to maybe ?

The HDMI Power Inserter can solve this by providing up to 5V/2A of power to HDMI devices like scalers, splitters or it can power an HDMI Enhancer (with built-in HDMI CDR and equalizer) to stabilize the signal and help to solve HDMI power issues.

But the cable is FIBBR, not Ruipro and there is no external voltage applied.

 

The vendor will talk to Sony on Monday and get back to me.  Their experience of these projectors is extreme reliability, apart fom my specific problems.  I've dealt with the bloke concerned for the past 40 years+ and respect his opinion, honesty and integrity.  He told me the last failed HDMI in a Sony projector (and they sell a lot of them) was the one originally supplied to me.

 

I think he's inclined to put it down to co-incidence, but I can't help wondering if there's something else in play here.  I just can't figure out what that could be.  We have surge protectors built into the 3 phase switchboard and have had no electrical/lightning issues in the 12 years we've been here despite having a lot of electronic equipment plugged in most of the time.

Was referring to the hdmi cable before the bluestream switcher Tony ; you didnt say what its length or type was so to paraphrase what I wrote

if it is a mix of differing types some stabilisation may help ? Anyway  good luck sorting it out ; I dont envy your luck;  hdmi can have troubles with very short cables too anecdotally [lumagen doesnt like them]

The cables going into the HDMI switcher are just reasonably ordinary 4K capable cables from a computer, Foxtel IQ and Panasonic DVD player.  They include the generic one supplied with the foxbox to an Audioquest Chocolate  for the dvd player.

 

I guess I'll just leave it to the retailer/installer to sort it out, but I wish I had a clue what the true anwer is.   Apparently they use the FIBBR/Sony combo all the time without problems .
