Mega865 - No LCD Display

I' have the problem describe in the "Important Threads - Things to know before (and after) building a Mega 865".
When I receive my Mega865, i tried it without processor and it seams works well. So I assemble it to work in PC mode and all is OK too.
Because I had the sound problem (no device found), I read the "Important Threads" and so I realise that my LCD display was not working too (i only use PC mode at this time).
I don't know if the two problems are in connection.
The sound problem disapear but I have still no Front Lcd Display.
I flashed the bios with the new version (1.3) and verified all the connectors that i could see.
What can I do more ? Is my MoBO dead ?
Thanks for your answer.
Vincent

i think it might have something to do with the proximity sensor and that sensor disables the phone functions when in call mode so that you do not accidentally press any other buttons.i think that it disables the touch screen when you put it close to your face.  once you hand up the phone, it returns to normal operations right?

  • Creative MP3 Player (Microphoto) Blank LCD Display Scr

    [size="">Hi, The LCD Display Screen on the Creative MP3 Player is blank. The blue background light will come on but nothing on the screen. I saw that it was suggested to update the firmware, however, I have no idea how to do that. If someone can explain to me how to do that I will try it. Or maybe you can suggest something else that I can do. I already tried several things suggested on your website, like removing the battery and installing it again, etc. I would appreciate it if someone would help me. Thanks!

  • Problem with LCD display on 17" iMac G4

    The LCD display on my iMac went wacky on me yesterday. It's as though one of the three primary colors no longer works. The screen has a green tinge to it, and anything that's supposed to be black shows up as green. I've reset everything, run the Hardware Tools diagnostics (no problems found), and changed resloutions, monitor depth, and brightness levels many times. No luck. The screen is readable although very ugly.
    Obviously I can take it to an Apple Store, but does anyone have any idea what it might be? I've searched the net and the forums and can't find anything close, but I know I can't be the only one to experience this problem. I called a mac repair shop a few minutes ago, and they said that the logic board would need to be replaced. I just can't believe that because nothing else is a problem.
    Please help. Thanks.
    17" iMac G4 1Ghz   Mac OS X (10.4.6)  

    I "fixed" the problem a few days ago. Digging around here in the forums, I found another thread that gave explicit instructions on how to open the iMac and re-seat the connections. Here is the link (http://discussions.apple.com/thread.jspa?threadID=196785&start=30&tstart=30). It's a post from Androcles made on 3/26/06.
    Just as he indicates, when I did this I found nothing to be loose at all, however upon putting it all back together, on the 2nd re-boot all was back to normal and still is. It's amazing how clear and crisp the screen is after suffering through the green hue for a few weeks...
    Good luck, and feel free to ask me for help if necessary.

  • About monitors and LCD displays

    I want give you some directrices about the display sub system.
    Like you all know there are CRT monitors and LCD displays.
    CRT
    CRT monitors are based upon electron beams hitting Electroluminescent phosphorus. In these monitors the most important parameters are:
    1) Dot pitch
    2) Refresh rate
    Dot pitch is the size of a single phosphorus point, smaller is better. Typical values range between 0.24 and 0.25. Beware with monitors having a not constant dot pitch, there are monitors with dot pitch of 0.24 at center of screen and 0.25 at the borders. I recommend monitors with constant dot pitch size across all screen.
    Refresh rate is the number of times a single electron beam travels across the screen drawing a single frame (from left to right and top to bottom) each second. It is measured in Herz (Hz). Bigger is better. Typical values range between 60 Hz and 120 Hz and the value depends upon resolution, more resolution goes to less possible refresh rate. If you are going to play games with shutter glasses, make sure your monitor is capable of 120 Hz minimun at the playing resolution. In 3D Stereo, each full 3D frame must be drawn 60 times/second (60 Hz) but a 3D frame is a single right eye frame and a single left eye frame, 60 Hz for left frame and 60 Hz for right frame are the full 120 Hz. If you CRT is not capable of these 120 Hz your eyes will suffer fatigue / strain and you would have a great headache after prolonged time periods.
    LCD
    A LCD display do not uses a electron beam to excite phosphorus and generate colored points, instead this it uses a grille and a special lamp. Instead drawing a frame line at line from top to bottom and left to right, it renders the frame in a step only and continuously, these displays are flat for this, there is no necesity for high voltage and magnetic fileds to move the electron beam. In these displays these are the more important parameters:
    1) Dot pitch
    2) Response time
    3) Number of colors (color space)
    Dot pitch is the same as with CRTs
    Reponse time is the time it gets going from pure white to pure black. Less is better. It is measured in miliseconds. Good typical values range about 16 ms. If you are going to use the LCD to play games, response time is the more important parameter at all.
    Number of colors are the simultaneus colors in screen. It have a inverse relationship with response time. It is measured in million of colors or bits. 24 bits of color depth are 16.7 million of colors. Typical values range agout 16 / 16.7 millions. Greater is better. LCDs with 16 ms response time have, usually, 16.5 millions of colors.
    Somethimes, the manufacturer will provide you drivers (setup or inf files) for your operating system. I recomend install this drivers. Don't panic if there are no drivers for your display device, Windows, probably, will find the suitable driver for your brand and model.
    If you have a CRT and you are stuck at 60~85 Hz you will need the right driver because Windows would not have found a suitable driver from its drivers base and it chose a standard monitor driver.
    If you have a LCD and you are stuck at 60 Hz, all is fine, as i have told you yet, LCD displays paint the screen continuously, you will not appreciate any flicker at 60 Hz in these devices. You can check this if you have a digital camera, make a photo of a CRT with a shutter of <monitor refresh rate> * 1.5. You will see a partially drawn picture. If you take a photo of a LCD with the same shutter rules you will get a full picture. With LCD you will get full pictures always, independently of the shutter.
    I hope al this info will be helpful to you.

    I have found a very interesting link on the Anandtech Web site about LCDs, it is a old one but i think it will be useful.
    The link is this

  • Mac Mini LCD Display - finally got it working but....

    Hello,
    I've posted on here many times about using the mac mini with my LCD display. The display runs at 60hz and a 640 x 480 resolution. For about four weeks, the mac mini would not connect to my screen. I installed display config x and had something of a result. By loading the mac mini up with my old pc monitor plugged in and then switching the vga plug once the mini was loaded, I managed to get a picture!
    Just when I thought my troubles were over, I realised that when the mini went to sleep, if I woke it up I had exactly the same problem. I would have to plus it into my pc monitor, wake it up then switch it with my LCD VGA cable.
    Is there anyway round having to do this every time I want to use my mini?
    Thanks

    Check out the manual for "Autoload" -- that's the name of the song file that's automatically loaded each time you start Logic or create a new file. You may want to look at some of the Peachpit books for walking you through creating this file to match your studio and workflow.
    Use Caps Lock to bring up a little keyboard on the screen that you can play with your computer keyboard.
    To change a track's icon, make sure you can see the track's info in the Arrange window. First select the track you want to work with. Pressing P toggles the properties column on the left. You may have to open up one of the areas using the little drop-down triangle thing, but you'll see an icon for the track in the properties area. Click and hold it to bring up a list of icons. You can create your own icons in the png format. Read the manual if you want to add your own images to Logic's standard icons.

  • LCD display not working (blank screen)

    One day old 15" G4 (the latest model). No major changes to configuration; only basic software installed (Adium, Messenger, Firefox, Remote Desktop).
    The LCD display stopped working during normal operation (web browsing) and I assumed it was a power management issue (I was running on a low battery). I unplugged all devices, plugged it in and rebooted (per instruction manual); same issue.
    Since then, I've zapped the PRAM, booted with "R", reset the NVRAM, and reset the PMU. I also tried loading the setup CD with the "Option" to get the hardware check; this may have given me helpful data but I can't see the display so I'm not sure (read: display doesn't work even when booting from CD).
    External monitors work fine still. The Mac boots and everything loads perfectly. I can adjust the screen brightness on the LCD using the F1 and F2 keys; the display responds by varying the backlight but it is not rending the GUI; it remains black (or dark gray, really).
    I'm experienced with computers but this is my first time working on a Mac, so I'm completely unfamiliar with how to troubleshoot these things. Any help you can provide is greatly appreciated.

    Hi
    This is exactly what has happend to my PowerBook a few days ago. Its only just out of warranty too. Man I wish I bought Apple care!!!!!!
    PLEASE, PLEASE, PLEASE, could you tell me what it was? Was it the inverter? I'm miles away from an Apple store (yes I know I live in the UK and its a small island, but its still miles) and woulf like to try and resolve it myself.
    Works fine on an external LCD. Tried everything!

  • 17" Studio LCD Display connect to G3

    I recently purchased a 17" Studio LCD Display which came with an ADC to DVI adapter.
    Then I picked up an adapter, but it was the wrong kind. It was DVI to VGA which still required the present VGA/G3 adapter ... the connection was going through three adapters that way. The monitor didn't light up. When I pressed the On/Off button (bottom right on front of display) the button lit up while my finger was on it and then faded to dark when I removed my finger. The system did not recognize the connection on the pci card either. I was able to hook everything up physically but the display didn't go on.
    When I plugged the UBS pigtail in, my system could see and recognize the monitor on the UBS port. So apparently, the driver software won't be a problem.
    Rather than putzing with adapters and connectors, I'd prefer to swap out the VGA card with a DVI video card for the G3. Is there such a video card available for the G3?
    Is this even feasible?
    The reason I need to keep this G3 is because it has a SCSI port (running Classic 9.2.2) which I require for an expensive high end scanner. Until I can find a comparable unit compatible with my new iMac I'd like to keep the G3 but would really like to hook up the lcd display on it.
    Any ideas?

    Exactly my problem too (and many others surely!)
    I have a macbook and a 17" LCD studio display which has a plug with 30 pins. As understand it, it is a DVI-I dual ink.
    I was about to buy the DVI adaptor from the mac store as it would appear to do the job but I learned that it is DVI-D and not DVI-I as is required. I searched for another picture of this adaptor (the pic on the mac store is decidely unhelpful) and it is clear from looking at it that it will not fit.
    Anyone know what to do here?

    Anywhere you can find it via the obvious Google search. It won't be from Apple, but will be a generic replacement.
    Why are you throwing away any future chances of out of warranty replacements when you drop or drown it?  Apple will give you a warranteed replacement phone for $199 (in the US, roughly the same in your country)

  • Officejet 6500 709e LCD display doesn't display all pixels

    A week ago my wired printer stopped displaying all the pixels on the LCD display.  I can't, at this point, understand anyhting on the first or second lines.  So I don't know how much ink I have in each cartridge (which usually shows on the second line), because random pixels show up, not all of them, for each cartridge.
    Important to note:  The LCD display does not add extra pixels to the display.  It just leaves out pixels where there should be pixels.  So if it's intstalling a new in cartridge, I can't understand anything showing on the first line of the display because only a few pixels display as it's configuring the new cartridge.
    Is there a way to fix this?
    My printer, by the way, says it's "not connected to the computer" when I press the wrench button and then a help choice on the printer, but I have no problem printing from my laptop (HP Pavilion dv5-2074dx).
    Is there a way to fix my LCD display?  I've had the printer less than a year...

    Hello Jane0218,
    To be honest, I don't think that there would be much to do in this case. I think your best bet is to contact the HP support for your country and see if they can help you. If you bought the printer less than a year ago it is still within warranty so that shouldn't be a problem.

  • White screen after replacing LCD display myself. Help needed!

    I tried replacing the cracked LCD display, the fuctions on the iPod is still working but after replacing the LCD display it turns out to be white. I search the internet for solution but can't find any instead the possible problem. I found forums stating it could be the 'GPU chip' is fried on the logic board. I tried the cracked LCD on another iPod Touch 2nd Gen and found out that you could still see the outline of the lockscreen and time but when I tried on the original iPod Touch 2nd Gen it's just white, the same goes for the new LCD display. It's there any possible way to replace just that part without resetting the iPod Touch to its factory settings and how much would it cost?

  • Increase refresh rate of my LCD display

    Hey hey hey. How can I increase the refresh rate available for my LCD display? Should I increase the refresh rate? I cannnot find where to change it.

    There are different refresh rates that you can set, but I agree, 60 should be adquate. You can check this under Control Panel, Display, Settings, Then Click on Advanced, then Monitor. There you will see the refresh rate. Unclick the "Hide modes..." and you will see other rates which may not be able to be applied to your machine.

  • External LCD display

    Dear All,

    1024x768
    1152x768
    1280x852
    But the 19" LCD display can support 1440x900. But I can't find this resolution in above table. But I found the following info at ATI website.

    G'day mate
    Thanks for the reply from Oz.
    Just had another good look at the back of the external LCD and it has got both VGA and DVI ports on it. Which will get the best results do you think?
    Also here is a dump re the graphics card in my iMac -
    GeForce FX 5200:
    Chipset Model: GeForce FX 5200
    Type: Display
    Bus: AGP

    Core Image: Supported
    Main Display: Yes
    Mirror: Off
    Online: Yes
    Quartz Extreme: Supported
    Display:

    As you can see, the card is a GeForce FX 5200. The web site refers to iMac G5's with GeForce FX 5200 Ultra cards and not the GeForce FX 5200. (My iMac is a Rev A machine).
    Do you think this will cause issues? I need to run the iMac and the LCD at a show for my company and I am a bit concerned that I might end up with a Mac with no working display. Is that likely?

  • Connecting an Apple 17" LCD Display to my PowerBook

    Hello
    I'm a complete novice at displays and I need some very basic advice!
    I'm thinking of getting an Apple 17" LCD Display off eBay. I know I need a connector/adapter and these seem to be also available on eBay although they do seem to vary from about £4 to £30! Do I need other connectors - say for power? What are the combined power connectors I've seen? I want to link it to my 550 Powerbook Titanium.
    Is there a specific connector I need? What do I need to look out for? Is there a reason why they vary in price? Is/was there an Apple part number I can look out for?
    Also, can I use the same connector to link up a non Apple display?
    What do people think about Formac flat panels?
    Any thoughts on what's best?
    Thanks Russ

    Hi, Russ. The Apple Studio Display 17" LCD (with a
    clear acrylic case) connects to a Mac through its ADC
    port, which is designed to feed video data, USB, and
    power to the display through a single cable. Your
    550MHz Tibook has a VGA-out port, which does not
    supply power to a connected display, nor does it
    supply USB to enable the USB port(s) on the display.
    Apple's system requirements for the Studio Display
    include an ADC or DVI port on the computer driving
    the display. Your Powerbook model has neither, so I
    suspect it can't drive the Studio Display at all.
    http://support.apple.com/specs/displays/AppleStudioD
    isplay17LCD.html
    All other LCD displays I've ever seen offered for
    less than $2000 are distant runners-up to Apple's
    LCDs in image quality. I don't recall whether I've
    ever seen a Formac LCD, but I would expect it to be
    comparable to the general run of the low-end LCD
    marketplace, i.e., cheaper than Apple's offerings and
    far inferior to them.
    When actual selling prices for identical items on
    Ebay vary widely, it generally reflects limited
    demand, variable supply, and differences in patience
    from one buyer to another. Someone who feels a need
    to "buy it now" will gladly pay a premium; someone
    who can take it or leave it this time and is happy to
    wait for a better deal next time an identical item
    comes up won't pay anywhere near as much.
    Thanks eww. But can I get an adapter which plugs into my vga port and converts to dvi? As I said in my post, I'm a no-hoper on all this stuff but I'm sure I've seen somewhere that Powerbooks like mine can display through an external monitor.
    I mentioned the 17" Apple display because I (like you) think they are the best. I'm not too bothered about the extra USB on the screen but what you say about power also is a problem Can I get a power supply as well as a connecting adapter?
    PS - I was also hoping to be ale to use the Apple display to give me a better view when using my G3 iMac DVSE but it looks that's a gonner too!!
