[Q] No HDMI output to LG 42LD420 tv! - Nexus 10 Q&A, Help & Troubleshooting

Hello!
Just got my Nexus 10 and I tried to connect the Mirco-HDMI out to my LG 42LD420 tv.
However, screen is all black and nothing happens. When I connect to my new PC screen HDMI port the image is mirrored instantly and it just works...
So I guess theres some new standards in Micro-HDMI that my TV doesn't support?
Just wanna clear this problem by making sure its my tv. And btw, other devices works just fine on the tv HDMI port...
Thanks for any info.
Simon

Whenever HDMI has problems it's usually HDCP that is the culprit.

Thanks! Googled some about it and I realize the problem New TV then I guess or try with some adapters to analog input...

I just ran into this the other day myself with a Samsung TV. I thought maybe it was the TV was only capable of 720p or something...
I'd get sound through from the N10, no picture though.
Also tried an MHL cable with my GNex and nothing as well.
Both devices work no problem on either of my PC monitors, and the PS3 has no problem with that cable/port on the TV.
Are there any workarounds?
My quick search indicates that it's possible that it can be cable specific? ie. Will work for some devices but not others? Does that even make sense?

[Q] hdmi adapter+720p hdtv=no video?

So i bought a mini hdmi to hdmi adapter for my transformer. Fits perfectly. I connect it and the tf goes into hdmi mode, my tv flicks then says no signal. My tv is an older samsung 32 inch and only does 720p. I get no video from the tf to tv. Is the output from the tf only 1080p? I lost the tv rmote and dont know if there is something i need to switch on it. Help!

There is SEVERAL threads about this issue, mainly due to TVs and/or cable

Sound stops working when I turn off the TV

I watching youtube or playing music with the Q. Sound works.
I turn off the TV.
I turn on the TV. Video or music is playing on screen, but sound doesn't work.
I have to pull the power on the Q or even do a reset to get sound working again.
I'm using the HDMI cable that was included from Google IO and a samsung TV.
Anyone else see this problem?
I also have a question for people that ordered the Q from Google, does the HDMI cable come in the box or is everyone getting a 2nd box that included the special Nexus Q HDMI cable? I thought that was really weird they didn't put the cable in the box.

I don't have this problem sound goes on again as soon as i turn on my Samsung TV again, just tested it right now.
Oh and btw i didn't even get a HDMI cable with mine.. bought it from a dev expecting it to be in the box, but it wasn't there.. and it was BNIB unopened.. he got it at google I/O
i get no sound frequently. sometimes i turn it on and it works fine, using the hdmi cord btw. most of the time i try to use my q i get no sound
whats your setups? i.e. are you using a receiver, optical, hdmi to tv, but is there a tv outputting to somewhere else?
just hdmi cord going from the q to the tv. video plays but no audio. now i cant get it to work at all
using HDMI cable connected to a TV.
no receiver. TV speakers. very simple setup.
I see this issue on both of my Q's, both with the same setup.
now no matter what i try i cannot get any sound. same setup as you. very frustrating. im in canada and bought the q from someone who attended google io. (180$ for an unopened Q!!) the hdmi cord is in hdmi 1. if i switch over to hdmi 2 and back then i have no video too, until i restart the q. wtf am i supposed to do with this thing!!!! lol

[Q] i9505(int) hdmi through receiver

hey,
i can't get it to work through my av receiver (denon avr-1909),tv is lg 37lf66,or lf65,not sure now),of course i have 11pin mhl adapter from samsung,connecting directly to tv it just works,but not through receiver,it displays "Connect your device to the TV directly via the HDMI cable",i traced it to string "hdmi_connect_indirectly",which makes more sense than the message
so,is that some kind of protection,or what the ** is samsung trying to tell me? (this string is all that i can trace )
logcat captured as 'clear-connect-wait for text-stop'
that message "TvoutToast : Připojte zařízení přímo k TV pomocí kabelu HDMI" is my error message,only in czech lang
edit:forgot rom-currently omega 7,but the same problem was with stock,some earlier version,maybe a month back latest
I have the exact same issue on my i545 Galaxy S4 when using my Samsung MHL 2.0 adapter. It works fine connected directly to my TV, but not to my receiver. What's odd is that the old MHL cable for the S3 works fine with my receiver when connected to the S4
It makes me wonder if Samsung intentionally set it up like that. Hopefully someone can shed some light on this issue.
Problem connecting S4 through AV receiver
Hi Guys
We have the same problem - just upgraded our TV to Panny GT60 and AV receiver to Pioneer LX76 - connecting S4 to TV with Samsung MHL adapter works fine, but get the same message as above when trying to connect through the receiver (either using Pioneer's supplied cable & MHL port or the Samsung adapter via a normal HDMI port).
Contacted Samsung and had this response:
Dear Matt,
Thank you for contacting Samsung Customer Support.
I am sorry to hear the issues you are having in connecting your device to an AV Receiver. I can understand this is very frustrating.
Unfortunately with the HDMI output of the device we can only support a connection to a TV I am afraid. We are sorry for any inconvience but a connection to an AV Receiver is not a supported feature of the device.
If there is anything else we can help with, please let us know.
Our Customer Support Team love feedback! Share your thoughts on this response by completing the survey at the bottom of this page.
Kind regards,
Thomas

I've also emailed the MHL consortium as they list both devices (AV & phone) as "MHL compatible", but to be honest expect a similar answer. Pioneer think that it may be something to do with copy protection as if you can stream HD video via the receiver you could output it to a recording device of some sort.
Anyway, hope this helps,
Best
Matt.

Code:
Share your videos, photos and more on your HDTV! The MHL 2.0 HDTV Smart Adapter supports HD signals up to 1080p.
Connect directly to your MHL-enabled mobile phone with a Micro USB input to create an HDMI docking station.
Then, connect a standard HDMI cable for easy connectivity to home theater or monitor. In order to function,
the Adapter also needs to be connected to a power source via the Micro USB port on the adapter itself.
(HDMI Cable and Micro USB Travel Charger sold separately). MHL 2.0-enabled phones allow a higher charge
to be passed through the adapter, allowing you to play video without needing to attach a charger.
my home theater is denon avr-1909 + ue40es8000 and also my blood is starting to boil...
also(and i'm 99% sure this is in stock rom) there's option to select audio mode to stereo/multi-channel,sure to prevent piracy..
aaaand one more thing....i can play music to receiver when i disconnect tv from receiver(i could disable hdmi-cec,but you know.. ),so it appears,that s4 don't like more than one device on hdmi bus(as we know,that all devices must talk to sender i guess,in this case s4),so this seems as a bug to me....
i'd like to see any mention about galaxy s4 supporting only tv as hdmi device...
edit 4.9.: got +- the same answer as Matt ...still trying,because i believe this is bug,maybe cyanogenmod has some cure(i think i checked and it was the same,so maybe some closed cource firmware?)..let's hope for samsung fix

Cyanogenmod doesn't support mhl, does it?
S4/hdmi works with note2 or S3 cable
Hi All,
I also have the same issues with ET-H10FAUWESTA cable but hdmi output through my onkyo hometheater works with a cable for S3/Note2 from "Cable matters". I can't tell about mhl, i have not tried, but audio & video work well.
Hope it helps.
Regards,
Same issue
I'm having the same issue with my ET-H10FAUWESTA cable. It worked for a while before this, but now it's displaying that error as well, even when it does display through the receiver. I don't understand why it would stop and then start again. Why would they support 7.1 surround sound and 3D if you can't even put it through a receiver? My TV doesn't have 7 speakers and a sub woofer.

[Q] No sound through HDMI

I have a Tegra Note 7 and I cannot get the sound to work through HDMI. I connect the tablet to the TV using a micro HDMI cable and the video is fine, but there is no audio. Any solutions for this? Tablet is stock and rooted.

That's weird since mine has always worked fine, and there weren't any special settings to change or anything. I will say that the micro-HDMI port is kinda awful, and if the cable is wiggled at all, the signal cuts out, sometimes just the audio. You may want to troubleshoot by trying another cable and seeing if you have the same problem as well as trying this cable on another device with a micro-HDMI output, if any of that is an option.

MHL

I gather the Zenfone 2 has MHL capability - high definition video and audio (up to 7 channels) output to HDMI via a USB MHL cable/adapter. Has anyone tried connecting to a TV by this method?

GSMArena says that it did have MHL, but everyone who has tried had not gotten it to work, so I'd say it doesn't have it.

Good job I didn't buy an HML adapter I saw yesterday then
I tried to compile in Moorefield's HDMI into my kernel for fun the other day; not so great.
Phone booted up, but said that there was an hdmi connection ( without connecting anything ) and started overheating fast.
I'm guessing that there might be an hdmi connection on the board somewhere that connects to the microUSB bus, but it's soldered/jumpered over.

I think, it's full-featured HDMI connector reserved on SoC (in case if used in Android TV dongle), not MHL.
There is Intel WiDi wifi display service integrated in the Rom. How can we use that for wireless display to a pc or android/smart tv?
Mhl didn't work, tested and asked in zentalk, online chat support and in xda..
But i seen an apk with name hdmi don't know what it is for
