Video output failure

I have a 2008 black MacBook, a Mini-DVI-to-VGA adapter and a Mini-DVI-to-"Video" adapter (AKA a Mini-DVI-to-RCA-and-S-Video adapter). The -to-VGA adapter /was/ working fine.
After I got the -to-video adapter I was having some problems making it work. A few places said I had to set it to 50Hz (which makes no sense as NTSC is 60Hz, but anyway), but that option wasn't available to me. I poked around, and apparently made the video out go completely insane. Now, when I plug in either adapter (regardless of whether anything is plugged in to them), the screen goes blue for a moment as if it's detecting a new display, but then it just goes back to normal with no new display detected. Running "detect displays" manually makes no difference, and neither does having something plugged in on the other end or not.
At this point, I can't use video output for any purpose, which is sort of annoying ...

MacBook Pro 3,1 - no video output

My MacBook Pro is exhibiting signs of graphics card failure. I can't get video output from the main screen or the DVI port. Apple claims I need a pricy logic board replacement. Anyone else had the same issue?

One long repeating beep and no video output

Sometimes when switching on a system build with KT6 Delta , I get one long repeating beep and no video output. The problem usually is solved if I unplug the monitor cable from the vga card and plug it in again. Still, I am thinking why does this happen since the cable seems to be connected fine?

1 Beep: DRAM refresh failure
Explanation: The system is having a problem accessing the system memory to refresh it. Refreshing is done on all system memory to keep its contents active.
Diagnosis: This code usually means a problem either with the system memory or with the motherboard itself.
Continuous Beeping: Memory or video problem
Explanation: The system is producing constant beeping in no specific pattern, or a fast "ringing" sound.
Diagnosis: This is usually caused by a problem with the system memory, or possibly the video card. The memory is more likely--the system complains long and loud if it can't find any usable memory, as there is no way to even start the boot process when this is the case. The motherboard itself could also be the problem.

I have already had some problems like this before with power failures but magically things worked again. This time was teh same. I got things working some times at random (really random lol) by taking power cables, reseting bios and turning back on but teh problem reapeared when I put HDD back and did not work again when I removed it. Now I can't seem to get it to display anything.
Any suggestions? Thanks in advance.
EDIT: sry I made a little confusion: It is a K8N Neo and not a K8N Neo2.

Keyboard problem, you think? What do you have?
Two things that are quite common:
Do not attach PS2 keyboard when there is power in the system.
Do attach USB keyboards when you are up and running in Windows.
This is not it, but Logitech keyboard drivers often complicate things.
I do use a PS2 kbd but never had problems with it (unlike teh PS2 mouse). I do not think it's kbd fault because it won't POST with or without it.

On startup Mac Pro I get a blue screen and a cursor on the upper left. The mouse cursor shows up independently. Is it likely a video card failure?

On startup Mac Pro I get a blue screen and a cursor on the upper left. The mouse cursor shows up independently. Is it likely a video card failure?

I managed to boot the computer and get the desktop to show. I now have a "repaired" computer. There are several problems that have cropped up. One is that I can only start up now in Safe Boot mode. Is there a way to turn it off? Also, I do not have a sound list, so I can't access anything requiring audio. Google Chrome only shows up as a white screen. Pictures that loaded before don't load in browsers, etc. Any suggestions? I figure I should reinstall Mac OS Lion for starts, maybe even do a mirror backup and reformat the drive. I think this drive has turned into scrambled eggs...what a headache!

How connect a 27 cinema display to HP Pavilion with VGA video output

how connect a 27 cinema display to HP Pavilion with VGA video output

If it is a thunderbolt version of the apple 27" display, you don't. The TB displays can only work with a TB source.
I also think you are out of luck with the mini-displayport versions of the apple 27" as well. This would imply converting an analog VGA output to a digital input of the 27". I suspect that there is not enough data supplied by VGA for that to work and I do not believe any adapters exist for this.

How can I do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder which does not have firewire out/input? it comes only with a component video output, USB, HDMI and composite RCA output?

I need to do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder (http://store.sony.co...ber=HDRAX2000/H) ..this camcorder model does not have firewire out/input ..it comes only with a component video output, USB, HDMI and composite A/V video output..
I wonder how can I plug this camcorder to the firewire port of my laptop? Browsing on internet I found that Grass Valley Company produces this converter http://www.amazon.co...=A17MC6HOH9AVE6 ..but I am not sure -not even after checking the amazon reviews- if this device will send the video signal through firewire to my laptop, in order to live streaming properly? ..anyone in this forum could help me please?
Thanx

I can't broadcast with the built in iSight webcam... how would I zoom in or zoom out? or how would I pan? I've seem people doing it walking with their laptops but that's not an option for me... there's nothing wrong with my USB ports but that's neither an option to stream video because as far as I know through USB you can't connect video in apple operating systems ..you can for sure plug any video cam or photo camera through usb but as a drive to transfer data not as a live video camera... is by firewire an old interface developed by apple that you can connect all sorts of cameras to apple computers... unfortunately my new sony HDR-AX2000 camcorder doesn't have firewire output...
thanx

Vga or dvi to video output to NTSC TV viewing

GEAR: I have a G4 dual 1.25 (silver double doors) with an ADC and DVI output in the back.
OBJECTIVE: I need to go from that to an NTSC TV so I can see what my edits look like.
NOT SURE: I have seen the Apple adapter (http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/7200505/wo/0K4TK pkMz7f922WszZYxFQMUy31/1.0.19.1.0.8.25.7.11.2.3) but it says it is for the MAC mini and the G5 only... does that mean it won't work for me?
OPTION B: Is getting a video card with an RCA or S-video output a better idea? If so which one? I am using both the ADC and DVI ports for two monitors, but would nuke one if necessary because I have to get this TV viewing capability up and running.
OPTION C for CANOPUS: I have also thought about the Canopus ADVC 100 or 300 so I can capture video from sources other than my DV Sony DSR-30. Right now, I have to record everything (everything that isn't DV) to DV on the DSR-30 before turning around to send it via firewire for capturing in FCP. Would the Caopus ADVC 100 or 300 also solve the TV viewing problem as well?
THANKS: in advance

Firewire to a DV/analog converter to your NTSC monitor. The only way for DV.
the DV/Analog converter can be either a dedicated converter (eg Canopus), a DV VTR deck (eg Sony DSR-11) or a camcorder.
the other options are not what you need.

TV (video) output from new nano looks very good!

Just a comment for those who may be wondering how the video quality on the new iPod nano looks when output to a TV. I have one of the old iPod AV docks with the s-video port and the new nano seems to work fine with that combination (using a standard s-video cable between the dock and the TV). Thus far I'm really impressed with the video quality, I can't see a single problem, the color is good, the quality and sharpness is as good as I've seen from any iTunes Store content, and as far as I can tell the frame rate is fine (no stuttering, skipped frames, or problems with audio sync). I'm amazed that such high quality video can come from such a small device. If it continues to look this good (after viewing more content and after more testing) then I think Apple may have "hit one out of the park." This thing could turn out to be the most popular iPod yet (if you have any interested in video and still want a small device).

I just found out that the video out (TV) on the new nano supports video playlists so you can create playlists for back-to-back display on the TV. Not even the AppleTV will do that (even though the latter has been a highly requested feature for the AppleTV since day one). In fact, if you can do without the on-TV menus you may find that the nano is a better video output device than is the AppleTV (that is, the menus system on the nano doesn't appear on the TV output).
Also, I just competed a few hours of video playback to my big-screen TV from the nano and I'm still impressed. No video problems at all, looks very good considering the quality limitation from the content that is currently on the iTunes Store (limited to standard definition, no HD movies, HD TV, or HD music videos as yet).

My new (2 weeks old) Macbook Pro, wont send video output signal to beamer... What can I do? I have the adapter to vga but it does not work...

Hi, I have a new MacBook Pro and I dont get video output to a beamer although I have the regular
Mini DisplayPort to VGA Adapter and it works fine with my older MacBook...
Thanks a lot for your tips...

That should work. When you first hook it up it will probably have the display set in Extended Desktop mode. The Menu Bar and Dock will be on the MacBook display and your background screen on the TV but you can move the cursor onto the TV screen.
In SystemPreferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen. You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
Or if you want to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box.
If you also want audio you'll need audio cables to the TV using a 3.5mm stereo headphone jack to RCA sound plugs. You attach it from the headphone jack of your MacBook to the appropriate input plugs on your TV http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=min i-dvi&x=9&y=13#/ref=nb_sb_ss_i_2_19?url=search-alias%3Daps&field-keywords=macboo k+audio+cable&sprefix=macbook+audio+cable&rh=i%3Aaps%2Ck%3Amacbook+audio+cable

MacBook Pro to TV, Video Output Too Dark

Hi,
I have an 2010 model 15" MacBook Pro i5.
I got this video converter for Christmas:
http://www.amazon.com/VideoSecu-VGA2TV-Computer-Presentation-Converter/dp/B000X3 FAJU/ref=sr14?ie=UTF8&qid=1295210644&sr=8-4
Using this in conjunction with an Apple Mini DisplayPort-to-VGA adapter and a standard RCA video cable, I am able to connect my MacBook to my TV so I can stream video from sites like Hulu.
My TV is a Sanyo flat screen CRT that's, probably, 6-7 years old (exact model probably isn't important).
I have no issues with the quality of the video output I'm getting (i.e. resolution, color). The issue I'm having is that the video is too dark. The video looks great on my MacBook screen, but the TV display is too dark. I have tried playing with the settings on the TV and on the converter (through which I can adjust brightness, contrast, saturation, hue, and sharpness) and I can't, for the life of me, get the output to my TV brightened up to an acceptable level.
I have tried to use the display calibration tool in the Mac's display preferences and that didn't seem to help (I'll admit that I don't think I'm doing it correctly).
Can anyone suggest some steps that I might try in order to improve my video output?
Thanks.

S-video output B&W

Hi,
From time to time I like to connect my PowerBook to TV thorugh S-video (using adapter S-Video to scart) to watch movies with friends etc.
Though, it has been some time (over half a yar) when I last watched a movie on TV that way. Since I know for sure that I have been able to connect my pb to tv via s-video with no problems I can't understand whats wrong now.
Here's the thing. When I connected my PB to a TV now, it shows the picture in black&white on the TV. Anyone know how to get back the colour image? I have the same cable set that I used before to connect to tv (latter is the same one also) without any problems - full colour. So, I think the problem is software-related (maybe os x update).
Can anyone recommend what to do to get the colour back?
cheers,
r. pello
P.S. PB's lcd screen works fine. So, problem only with s-video output colour.
PowerBook G4 (1.67 GHz, 15") Mac OS X (10.4.9) iMac (Summer 2000, 120GB HDD)

Have you checked the resolution/TV type in the Displays preference pane once the TV is connected? If your PB is detecting your TV as PAL rather than NTSC (or vice versa), that could certainly cause a loss of colour like you describe.

IMac g5, no video output

I just replaced the logic board and power supply on my G5 imac, both of which were bad. Now, when I power on, all three LEDs on the logic board come on, t there's no video output. The video had been working fine before the logic board and power supply failed.
THe tech note says to try resetting the PRAM. We have a wireless (usb) keyboard, and holding down option-apple-p-r doesn't seem to do anything. Is there another way to reset the pram?
Any other suggestions would be welcomed. Replacing

THanks Moke.
OK, I bought a wired keyboard and tried to reset the pram. I think it worked -- it rebooted the computer and the chime came on again. But there's still no video output. Not sure if that means I should replace the screen or the video inverter or both or if it could be something else altogether.
Any ideas?

IMac G5 iSight - Resolution problems when using s-video output.

Good afternoon all.
I have an iMac G5 and the only video output it has is a mini VGA socket. I have used this with a mini VGA to S-Video converter cable from Apple and am getting some odd results.
The Mac is running Leopard 1.5.7 and I'm outputting to a fairly old Panasonic CRT TV.
The problem I find is that when I plug in my mini VGA adaptor to the Mac it reduces the resolution on the Mac screen down to 1024x768 (stretched). The TV outputted TV image looks great, but I can't seem to keep my native resolution of 1440x900 on the Mac display.
If I do go and change the resolution in "displays" in the sys' prefs' then it just seems to keep the 1024x768 resolution on the Mac but this time without stretching it.
Does anyone know how I can keep my Mac at its native resolution of 1440x900 while still outputting to s-video to the TV?
Any and all help will be greatly appreciated.
Thank you again in advance.
Stuart

Hi
I have the same config as you: I have been using it for years to view on my tv dvds or videos from the web.
To my knowledge there is no way to acheive what you wish: when you plug the adaptor in the mac adjust to your output source and its main display (the g5 display) will reflect that with the result that it becomes very difficult to use.
Maybe there is a way to try changing the resolution in a middlle"configuration" which would give an acceptable viewing on the tv as well as on the g5.
Personally I keep plugging and unplugging the adaptor as needed.

Lost S-Video Output

I have been using a G4 Powerbook 17-inch, 1.33 Ghz connected to an NEC VT470 LCD Projector through the S-Video output (Mirroring). It had been working just fine until recently - the s-video output stopped working. The odd part of this is that if I connect through composite video and the s-video to composite adaptor,It works. I have confirmed that the s-video input of the projector works, and i've tried the same thing on a 52" DLP rear-projection TV with the same results - composite video through the composite adaptor but no s-video straight through the s-video output. This makes me wonder if there's just a setting that's been changed or turned off. Another note: the Powerbook will not "detect" the projector when connected through s-video, but it does when using composite through the adaptor. Any ideas?

That does sound like a faulty video card - I just read another post regarding faulty video card - in that case replaced under warraty by Apple.
