WARNING - Sky HD may have bust my Lumagen

[dgc]

You may have seen the posts in the Sky HD section about the Sky HD box causing problems with HDMI gear - some suggesting that there may even be permanent damage to hardware via electrical discharge.
More likely it seems that the Sky box is corrupting the software on the HDCP equipment in the plasmas it is connected to. Result is that the sky box then says the plasma is not hdcp enabled.

I believe the same has now happened to my lumagen. I have sent Gordon details but for now please bear this risk in mind.

Just to let folk know it is not possible for anything to write new keys to a Lumagen through the DVI port. So this is not going to be the issue wih this unit.

It may of course be something else...I'll be investigating immediately.

Well having now read the email I would suggest that ANYONE with a SkyHD box and ANY display or scaler that is HDCP compliant should disconnect their HD+ box and use component from it until such time as a solution is found to this problem.

As I said above it's not possible to corrupt data in a Lumagen by writing to it so it would appear to be an electrical issue which potentially could affect all devices you connect to I'd imagine.

Strange, my Iscan HD+ does not process the component signal from the SKy HD box , the info screen says it using passthru only. The Iscan process the HDMI fine. The screen (PDH8) processes the component OK when sent directly from the Sky HD box.

SROLLINGS: If you go to the plasma section and read the issues with the SkyHD+ you will find that it ONLY affects the HDMI/DVI inputs of products that are HDCP compliant that are connected to a SkyHD+ box. What the SKYHD+ HDMI output is doing is unknown at present but it does appear to be doing something. Not every device attached is failing and it is not an "instant" death. Usually it seems to take a few days for the symptoms to become present.

Until this morning I wasn't actually concerned as I thought it was a Key issue with HDCP. Now I am though as I don't think it is a key issue. I've asked the original poster here to try something before I look at the scaler to see what has happened to it. Might help get closer to the problem, may not.

Quick post before I get some work done.

I'll be trying Gordon's suggestion this evening to see if it makes a difference and will report back then.

Fingers crossed this is a set up/settings issue - but it was working ok before suddenly failing. I'd prefer to be at fault myself than have a damaged lumagen.

Aren't I glad that I didn't have SkyJD installed!

Joking aside this is a very damaging situation that Sky have got themselves in. I do hope all the customers affected are re-imbursed any repair costs.

I have got the sky hd+ supplying my Iscan HD+ with HDMI to DVI and it works well. My problem is that i have also tried to attach the Sky Hd+ by component it does not send a picture the PHD8 , the info button from the Isc shows the signal as passthru not component and all I get is a blue screen.

The iscan hd+ will not send component hd out via DVI. It must be sent out via VGA in analog

Thanks for that, embarassingly just read the manual and seen it.

I've now had chance to try Gordon's suggestion and it made no difference - still getting the "HDCP message" via HDMI.

I've done some more playing with connections and sent Gordon the results.
It may be something obvious that I'm missing but I cannot understand why it was working ok and then suddenly failed. I can only conclude at this stage that the Sky HD box has altered the Lumagen in some way.

I emailed tech support at Sky yesterday but no response so far.
Gordon has kindly offered to come and have a look when he is next in my area. The standard of service couldn't be different.

For now I'll have to use component

I've only just come in on this so I am not up to speed, but is the problem occuring when using other HDMI sources when subsequently connected to the HDMI port that the SkyHD box was prevuiously connected to?

If an alternative source did work (ie an upscaling DVD player), then it could well be the Sky HD box corrupting its own HDCP blacklist and nothing to do with the display (or other sink such as a scaler) being damaged. This scenario would still fit in the case of the case of the Lumagen. It may be that Sky intentionally (or unintentionally) sent a SRV to revoke the KSV of the attached display. So its not actually damaging the display (or scaler) but preventing the SkyHD source from talking to the display.

Fingers crossed for an own goal for Sky HD.

[Gordon @ Convergent AV]

Unfortunately other HDCP devices do not work after the SkYhd box has done it's black magic.

Lumagen now think that an overvoltage on the HDMI output of a device could fry the I2Cbus. This would stop HDCP handshaking (and edid conversations) but would allow non HDCP sources to still work...which appears to be exactly the scenario that many have. So UNPLUG HDMI now until Sky fix it.

Hi Everyone.

I have an IScanHD+. Sometimes when I come home from work and switch the kit on, I notice that the IScan is locked up, outputting a purple page to my screen (i.e. like a blue screen, but purple). Unpluging & repluging the mains to the iscan fixes the problem. is this related?

(edit) I should say, of-course that this only happens with skyHD

[timmorris]

Is this something that is likely to be fixable in software or are Sky going to have to recall several thousand boxes?
