No Signal on HDMI TV After Lion Upgrade

I just got off the phone with Apple support, they gave me these terminal commands. Works so far for my Philips 37PFL9603

cd /System/Library/Displays/Overrides/DisplayVendorID-410c/

sudo mv DisplayProductID-0 DisplayProductID-0.old

Reboot after entering the commands

Good luck and enjoy!

Same issue here, new mac mini lion and philips tv. I called apple care and they helped me out. I was asked to execute the commands shown below in a terminal window and reboot afterwards while the mac mini was atteched the philips tv

cd /System/Library/Displays/Overrides/DisplayVendorID-410c/

sudo mv DisplayProductID-0 DisplayProductID-0.old

This worked for me and after reboot i was able ti use mynew mac mini running lion with my philips tv using a direct hdmi connection.

I think these commands are the same as shown in the post of Venturas.

I had the same issue with my new mini mac and philips tv. Called apple care and theyasked me to contact philips, I contacted philips and they advised me to contact apple again so I called apple care again and explained my issue again and after that apple care had a deeper look into the issue. They asked me to perform the commands shown below from terminal. I could do this over vnc.

cd /System/Library/Displays/Overrides/DisplayVendorID-410c/

sudo mv DisplayProductID-0 DisplayProductID-0.old

For philips tv using hdmi these commands are working as reported in several cases within this thread.

Kind regards

I have the same problem:

New Mac Mini 2011 / OSX Lion. No picture using HDMI on Philips TV. Just the white 'start up' screen at the beginning. After that everything goes black. It does work on my JVC TV and another monitor.

One quick question;

does the problem also occur with the mini display (thunderbolt) port or is that going to work?

I'm thinking of:

Mini Display Port -> DVI -> HDMI

thanks

I have the same problem, and it just got worse today. In the last two months I've experienced this a couple of times, but today my Mac mini is really giving me a hard time. I have my Mac mini connected to my Denon receiver (together with a PS3). So HDMI1 is for the PS3, HDMI2 is for my Mac mini. Today I lost the connection after playing PS3. When I return to my Mac mini it just says stereo on my receiver (should say multi channel in).

In order to fix this i shut down my Mac mini, turned off the receiver and my TV. Then I turned on my receiver and TV, and THEN i started the Mac mini. This finally gave me the connection back. Not sure if this was just luck or what...

Thankfully I have shared the screen to my iMac, so I can turn my Mac mini on and off from there.

Apple need to fix this bug ASAP!

Hi there,

I bought a brand new MBP 13'' a couple months ago, updated to Lion 10.7.2 and installed all the software updates available up to yesterday, Jan 18.

Today I made my first attempt to connect my Samsung LED TV to the MBP using the same cable and HDMI port I've been using for 18 months to watch movies from my HP Envy notebook without a single problem.

After plugging the HDMI cable to the Thundebolt -> HDMI adapter my Samsung TV showed a "Waiting for signal" sign on screen for about 15 seconds, followed by a "No Signal" sign. I tried every single solution from this thread: unplugging the HDMI cable, plugging it again, turning off and on the tv, turning off and on the MBP with and without the HDMI cable attached, etc. I had no luck, the "No Signal" sign was always there.

Then I plugged the HDMI cable again to my HP Envy and it worked like a charm, so the MBP was the problem.

My Samsung TV have 4 HDMI inputs (HDMI 1 to 4). I always used HDMI-1 from my Envy without a problem, but decided to give a try with the other ports. HDMI-2 and HDMI-3 showed the same issue, but when I plugged the cable to HDMI-4 the screen suddenly became blue for a few seconds, my MBP recongized the Samsung TV and finally the problem was solved.

Curiosity took me further in my "investigation" about this strange issue, so I plugged the HDMI cable back to HDMI-1 port and it worked. Also HDMI-2 and 3 are working now!

Does anybody experienced something like this? Mi external display now works flawlessly, but the solution was even stranger than the problem.

Greets,

Nicolás.

I have the same issue as many else. My AV-receiver (Yamaha RX-v667) can't conect with the mac mini in 1080p @ 60Hz, from 25 Hz and lower it's OK. If i boot in windows it says 1080p @ 60Hz.

At the moment i use 720p in Lion (works fine with the receiver) but when i check what kind of signal the reciever it says "???->???" . Probably it's a hand-shake problem but how do i solve it so i can use 1080p in lion?

I have a Mac Mini -> Reciever -> Projector setup in my home theater.

I am using the Denon 2112 and absolutly love it. I had the issue being discussed here with I first update to Lion. I updated the EFI and it was solved for me.

Hope that helps...

Lion 10.7.1 has gone live for download, fixes HDMI output video and audio issues.

Just applied the 10.7.1 update. Definitely seems to smooth out the HDMI negotiation with my Philips TV. I can turn the TV off and on without a lot of blue and green flashing and static now.

i have the same reciever, and the same problem. Yamaha dude told me that it's a known issue, and said I should try with a HDMI 1.4 high speed certified cable. Haven't had the time to try it out yet.

Well mine has stopped working totally with my Phillips LED, thankfully it works on my two year old Isignia 52" (which is weird because it's kinda a inferior brand) so I hooked it up to my living room TV and restored to 10.6.8 from my last Time Machine backup from that OS. Works flawlessly again, I guess I will just wait until 10.7.1 gets pushed out, and it better **** well fix this or I want my 29$ back and my 49$ from Lion Server.

Garenda - Glad it worked for you 🙂

The software is demo, but i think(i haven't passed the 10 days yet, so just theory here) that if you just set up the display correctly once, it will continue to work even when the software expires, i don't see the software running in the background so i believe it just makes some OS X configuration changes/additions. If you don't need to make any changes afterwards, you don't need to start the program again.

Hopefully apple will have released an update by the time you need to make changes again.

Oh almost forgot to answer your second question, yes you need to have the mac connected to the affected TV, otherwise you won't see the correct display when you start the software to make the configuration change, but just setup up the screen sharing as i described, single user mode should display correctly on your TV, if not try resetting the PRAM by powering on the mac while holding down alt-cmd-p-r until you hear the startup sound twice, then try booting into single user mode, if you still can't see anything.......i would type the three case sensative commands blinded....just give it 1-2 mins to make sure that it's completely booted into single user mode.

Did you also try the tweak mentioned earlier to disable HDMI 1.3 via SwitchResX? It seems there are also some that have success going that route.

Let me see if I can find the original post and poster.

Edit: Here it is. Posted by Samoel

Now that you've got desktop access the affected computer and it's connected to the tv:

• Download and install SwitchResX (10 day demo, google it)
• Start SwitchResX, select your TV on the left side:
• Click - Disable HDMI 1.3a (enables more resolutions on HDTV)
• Click - Default Resolution

  set it to 1920 x 1080 @ 50 or 60 hz (or the setting your television can handle or you prefer)

• Close SwitchResX
• reboot and the computer should start displaying on your TV, if not try adjusting the resolution.

There is an non demo free alternative to SwitchResX called DisplayConfigX which i'm in NO WAY SURE works with Lion or even can fix the problem, but it's worth a shot if you want to try something else.
