DIsplayport crushing blacks w/ panasonic plasma tv

I'm trying to properly calibrate a panasonic plasma for use with my mbp's displayport output. No matter how many times I run the apple calibration tool and turn up the brightness on the tv, the black levels are absolutely crushed (no detail in blacks).
If you are familiar with it, I am using the calibration disc made by the folks over at AVSForum, and am unable to get any of moving bars visible in the black level calibration screen.
Has anyone experienced this same issue and figured a way around it?

My main display is an HDTV. I set all my color settings on it, not the MBP.
If you're using a DVI > HDMI cable along with the DVI > MiniDisplay you should have no problems adjusting the colors on the TV itself.
My Sony XBR6 has different profiles for each input. My MBP and my 360 both require different settings. Yours should do the same.
I have had issues with newer nvidia cards (GTX295) and HDCP. They wold put out an HDCP compliant signal which would disallow me the ability to change any color/brightness settings on my TV. (Made my beyond furious)
I would suggest making sure that the color settings on the TV are actually being changed, and that something is actually happening as you move the slider or increase the numbers, however its set up. Play with the white/black levels as well. Try turning down the backlight...
Calibration discs can be very misleading. Your best bet is to put in a DVD and play a dark scene, adjust the brightness, then move to an outdoor scene. I still to this day need to fiddle with mine very occasionally.
One other thing to check is your TV's features. For example, mine has some stuff called "Gamma" and another called "Advanced CE" These solved my problem with contrast the second i enabled them.

Cannot connect Mini PPC 1.42 GHz to Panasonic Plasma via DVI-to-HDMI-Cable.

Saw this question many times but never found a real Solution for that...
I'm trying to connect an old Mac Mini Power PC 1.42 to my Panasonic Plasma. Using the DVI out and an Adapter to HDMI.
In the Monitor-settings, I can see that the PPC found the TV. It is shown as "Panasonic TV" in the settings when I connect the cable. This, I can see while using Teamviever on my iPad, because the TV stays black. The TV does not seem to receive any signal actually.
Does anybody know what to do? I can't imagine there's no solution.
Please help!!

Unbelievable but true! I've managed to solve the issue yesterday on my own.
For those who are interested and didn't find a forum that helped much, here is an easy manual:
Boot with normal Monitor using a normal DVI cable.
Start Teamviewer so you can follow the next steps on an iPad, iPhone etc.
Unplug normal monitor.
Now use a DVI cable with HDMI at the other end.
Plug in Panasonic Plasma TV by using the above mentioned cable.
Now the plasma stays black, no signal arrives. Look at the iPad via Teamviewer and open monitor settings.
This should show that the Panasonic has now been found.
Switch the resolution to 1280x720.
Tataaaaa!
The Plasma TV now proudly shows the content of your Mac Mini PowerPC. Play with further settings in order to optimize the display width etc. Set the TV to 16x9 manually.
Enjoy!

Connect Macbook to Panasonic Plasma TV

Hello,
I bought two cables for my macbook (1st gen), a minitoslink cable to toslink cable and a rca (red, yellow) to 3.5mm (headphones jack), and neither of them output sound. i do have the mini dvi to dvi cable to the video outputs find on the tv but the sound is a different matter. does anyone know exactly what to use or configure on the macbook/television? i really need help on this because i keep buying cables that dont work. thanks for helping.
Chad

I have a panasonic plasma also (TCP42S1) & macbook. Have the miniDVI to HDMI & HDMI cable in to the "HDMI 1" input of the plasma. But that's just the video, works fine. Audio? Could do the audio to another "input" of the plasma.
Need to somehow get the audio out of the macbook incorporated with the video from the MiniDVI out. Monoprice sells this "Mini Displayport Male and USB Male Audio to HDMI Female Converting Adapter" ??

Panasonic Plasma TV repair - Geek Squad

Hello community -
Two years ago I splurged, and purchased a beautiful 55" Panasonic plasma TV. I am frugal, and do not do this often, so I also decided to protect it with a 4 year Black Tie Geek Squad warranty.
Been very pleased with it, up until 20 days ago. When, it would no longer turn on. 7 blinking red lights, were the "code". Simple internet search showed a specific faililng component.
I called Geek Squad, who was very helpful and pleasant. And, arranged an appointment to have it replaced. Well, now that appointment has been cancelled for the 3rd time due to a parts delay. It is very obvious, that 1) This is a product defect, based on the # of issues people are having 2) This part will never arrive.
I just spoke with Geek Squad again, asking that they help me with a replacement. They quoted a 30 day period, until after which they cannot consider it. Only after 30 days will they "start" the process.
Question for the group ---- have you had this experience too? Have you found a way to navigate these waters? And, once I pass 30 days what sort of expectation should I have for actually getting a replacement?
I am normally very reasonable. However, my patience is wearing thin. And, I am VERY RELUCTANT to ever purchase from Best Buy again. They were my go-to brick & mortal and on-line store, but I've reconsidered that.
Thanks for your perspective. If anything, it is healthy to vent. Because I do not expect a good outcome.

Hello sledwith,

Once I have further details, I will be sending you a private message. To view your private messages, please make sure you are logged into the forum, and click on the envelope in the top right hand corner.
I look forward to continuing to work with you, and I will be in contact as soon as possible. In the meantime, please do not hesitate to let me know if you have any further questions or concerns.

Fluctuating brightness on 2011 Panasonic plasmas

Has anyone else encountered a problem with fluctuating brightness on the new 2011 Panasonic plasmas? We just got a 55st30 and were greatly dismayed to encounter brightness, then dark, then brightness when watching it. I have looked online, and this apparently is a widespread problems with the new st and gt30's. There has been some success with it going away after the 100 hour break in, or by turning off the CATS setting, etc. Does anyone else have the problem and what is the solution? SMV

My understanding on the topic is that it's not so much an issue with CATS (Can still occur when turned off), but an issue with the dynamic APL (Average Picture Level) ciruit, designed to limit the incoming voltage as the APL changes. Panasonic actually describes this as a "feature" (although it's not defeatable) and is used to increase the life of the panel, prevent overheating and stress on components, and reduce power consumption. Given the last couple years TVs "issue" with floating black levels (also described as a "feature") which was never fully addressed as a problem and never corrected, it's likely that it will not be fixed with a firmware update. If Panasonic truely beleives that this is a "feature", then in their minds there is nothing to be fixed.
Assuming that it IS the dynamic APL circuit, then any adjustments via firmware would also likely increase power consumption and possibly disqualify the TV for Energy Star. Panasonic would not do this since to the many customers who have purchased this unit with Energy Star advertised. This is just speculation, but looking back at how Panasonic has handled this similar issue in the past the odds of any "fix" coming are pretty low.

Hooking up MacBook to 50" Panasonic Plasma?

I am using the Apple mini-dvi to vga adapter along with a 6' vga cable to hook up my macbook to my 50" panasonic plasma (full specs: http://www.circuitcity.com/ssm/Specifications-of-Panasonic-50-Plasma-HDTV-TH-50P Z700U/sem/rpsm/oid/175537/rpem/ccd/productDetailSpecification.do#tabs)
My problem is that only half (maybe even less) of the listed resolutions for the external display (TV) seem to work. None of them take up the entire screen, and none of them look good. Image is shifted, fuzzy, cropped on top and bottom. OS X does not list 1920x1080 as a supported resolution for the TV.
Can anyone shed some light on this situation for me? I don't really know what i'm doing here!

Hi Mike,
If I am not mistaken apple stated that macbook support up to 23" external lcd using 1440 x 900 resolution.
Some user managed to go over 23" and slightly higher resolution. But if the screen doesn't run on its native resolution it will become fuzzy as you described earlier.
Try mini dvi to dvi and get one of the dvi to hdmi adapter like this http://www.gefen.com/kvm/product.jsp?prod_id=3570, and you might get some luck.
Good Luck.
Do consult your panasonic or circuit city guy before you decided to give mini dvi to dvi with adapter a shot.

Can't get audio to work on my Panasonic Plasma smart TV when I connect a Toslink optical mini to Toslink optical digital to my mid 2009 MacBook pro?

My MAc book pro 5.5 is mid 2009, Processor speed 2.26 GHZ MacOS X VERSION 10.68 Leopard. My Tv is a Panasonic Plasma smart TV TC-P50ST60. I ordered from Amazon a Toslink optical mini to Toslink optical digital cable meant for Macbook pro 2009 forward. I changed the settings on both TV and Mac but I still can't get audio to work on TV. I believe my Mac can't see the audio output from the TV. Any advice with step by step instructions on how to fix it? could it be they sent me defective cables? Thank You for your help.

When I spoke with Apple I made sure I told them that my Macbook Pro was Mid 2009 and he ensured me again that those to cords will work. I realize that with the newer models it does put through both sound and audio but because of my model I don't think it does obviously because I have played with both Sound on my computer and Sound on the TV and nothing works. Sometime Apple can be good but man some people lol he even told me he verified my computer model on the computer and that's what came up.
So new question would be what kind of cable would I be looking for to get audio? Anyone before I call back to Apple and see what they say hahah

AppleTV 3 only showing Apple logo when connected to very new Panasonic plasma - worked Ok with older Panasonic (2007)

AppleTV 3 only showing Apple logo when connected to very new Panasonic plasma - worked Ok with older Panasonic (2007) - have reset AppleTV, tried 3 HDMI cables.

Tried again as you suggested - no luck. Ref sequence below
A. Pressed menu & down to reset Apple TV
B after reset & restart pressed menu & up buttons to change resolution. After pressing both buttons for 6 sec, LED starts flashing - released both buttons. TV screen blank. After 20 to 30 sec horizontal lines came on screen remained for 20 sec then screen again went blank. Waited for couple minutes. LED still flashing - pressed Menu button for 2/3 sec - flashing stopped & LED glows continuously. Screen blank
C. Reset the unit again by pressing menu & down. When it restarted - while LED was still flashing, got orange color screen with Apple logo in the middle. This screen remained till LED stopped flashing & then screen went blank

Resolution issue on Panasonic Plasma HD 1080p with ATV

With my ATV2 set to Auto resolution or 720pHD, I lose picture on the left and right of my 58" Panasonic plasma HD 1080p TV. If I reset the resolution to 640x480, I regain the full image, but of course at lower resolution. Apple Genius was of no help on this issue. ATV2 software is up to date. HDMI connections are good. Will appreciate any help.

I've solved this issue. My Bose Lifestyle V30 Home Theater has no HDMI port for the 'AUX' input, which I had used with composite cables for my Apple TV1. I tried using the DVD HDMI port with my Apple TV 2, and for whatever reason, the resolution at 720p stretched beyond the screen and lost content. Now I've run the Apple TV2 HDMI directly to another HDMI port on the Panasonic TV and get full screen content at 720p (TV is set to 1080p). The Panasonic TV returns the Apple TV2 audio to the Bose. Using the Apple TV2 now involves one additional step in selecting the HDMI port on the TV, (and then returning to the other HDMI port for Cable and DVD) but I once again I have HD video and excellent audio. Such are the pains of mixing brands in a home theater.

No video from iPhone to Panasonic plasma TV

Got the AV composite cables from Apple to hook up to my Panasonic plasma to look at photos on iPhone. Why is there no video output on my TV?

First the obvious: you are hooking up the composite cables to a composite input, correct? Many plasma TVs will have component inputs (and should have composite as well) but it's important to insure you are hooking the right stuff to the right stuff.
Assuming for a moment you have the hookup correct, then the second obvious question is have you selected the composite input on your set? The easiest way to test is to hook up another composite source (say a DVD player or VCR) and make sure you can see it.
Next you will need 1.1.1 firmware on your iPhone, so make sure you've upgraded to the latest version.
Lastly, you may need to plug/unplug the cables several times into the iPhone. When you get a good connection and try playing a video or slideshow (and it will only show up when you actually go to play a slideshow -- you won't know until then) it should ask you on the iPhone whether you want to display it on the TV (and, of course, you answer yes).

Help hooking up IMac Chrome 24" to Onkyo tx-606 to Panasonic Plasma

I have a 24" iMac Chrome, a Onkyo TX-606 A/V receiver and a 50" Panasonic Plasma TV (Can't recall the model, but it is a 720p plasma TV). I ordered the DVI to HDMI cable, from Apple, to hook all this up together. The TX-606 and Plasma work great together with a DVD player and DirectTV box as sources. When I hook up the iMac I get a blue screen on the TV.
I can get the iMac to detect the device. It shows a screen panel for TX-606 and defaults the resolution to 1280x720, which I understand is correct. However, I can't get the TV to display the image. I've cycled the iMac, the TX-606 and the TV to try to get these in synch.
Any suggestions on how to resolve this? I think it has to do with the TX-606 but, since other devices are working correctly with it I hesitate to blame it.
Where do I start to debug this issue?
Shouldn't this "just work"?
Jeaux

hey there Jeaux & welcome to Discussion!
1-is your iMac video & analog stereo connected directly to TV? if so, select the input on the TV to
the one that has the iMac input.
2- is your iMac audio & video connected to the AV receiver? if so, you may need to select the input
on the AVR & the TV. AVRs look for audio inside the HDMI connection like you'd get w/ a BD
player, not separately like you have w/ the iMac.
3-check out the AVS forum for some good info in their Mac HTPC chat. see this:
http://www.avsforum.com/avs-vb/forumdisplay.php?f=115
my 17" CD iMac is DVI>HDMI to my 42" Sony @ 1920x1080i w/ a TOSlink optical to my Sony AVR, so i have a set-up like #1. but if you have a set-up like #2(had similar situation w/ using my HD cable box), i got no image if i didn't select the audio input on the AVR & the video input on the TV.
good luck.

I would like some guidance in connecting APPLE TV to a Panasonic Plasma 42" TV

I am connecting my new Apple TV to a Panasonic 42" Plasma TV that is about 4 years old. Model: PN42C450B1D. Any suggestions. I'm using Directv for my TV connection.

AppleTV is independent of other connected devices - you hook it up to the TV via HDMI NOT to other connected boxes, unless using an HDMI switch or AV amp to switch many HDMI sources.
There should be no problem running AppleTV with a Panasonic plasma - I have 2 which are as old or older and they work fine.

Panasonic Plasma TV does not recognize MBP

When I connect my MBP using HDMI to DVI to the TV, the MBP recognizes the Panasonic as an external display, but it seems the TV does not recognize the MBP. Same problem with PC connection as well. Can anyone help with other settings or is there a compatibility issue?
MBP works fine with LCD projectors.
Thanks!

I've got a Panasonic Plasma and it behaves fine ...
In System Preferences/Displays/Panasonic TV click Options and make sure 'Overscan' is checked, then set the other Display options as shown below.
If this doesn't work I'd suspect there's something wrong with the TV itself

Black line on plasma TV

I have a 42HP84 plasma TV about 7 years old. Last week I started having a black line about 1.5" wide by 14" ling coming down from the top of the screen. Toshiba support suggested I reboot the TV. Didn't help. Any ideas other than buying a new TV.

I have the same TV 42HP84. Per the Model sticker it was manufactured in July 2005. My TV developed a vertical black line a couple of years ago. I found nothing on Toshiba's web site or by phone contact that was any help. I did search "black line on plasma TV" through Google. I found several youtube videos that showed how to repair this problem themselves. I followed one of the videos and I was able to repair by TV myself. It took me approximately 3 hours with a drill with several bits and a soldering iron. Put the TV back together and it has worked fine up to just before Thanksgiving. I guess I will try a another repair effort before I trot out to buy a new TV.
Good luck.
