PowerPC :: Display Has Bunch Of Parallel Vertical Lines Running Down / Wifi Card Pooped Out
Oct 8, 2008
So tomorrow I'm going to be getting a Powerbook G4 from a friend. He says there are two problems with it.
1. The Graphics. I haven't seen it personally, but he says every time the laptop starts up, the display has a bunch of parallel vertical lines running down it. Is this a hardware issue, and is it easy to replace? Or can an update fix it? I wonder because isn't the integrated graphics mounted on the logic board?
2. The WiFi Card. I remember the day he got it, we both say the WiFi worked like a charm. One day, it pooped out on us. Now, the only way for internet is by ethernet. Did something possibly unhook from it, or is it a bad card? Once again, a possible update for it?
I won't know for certain until I get this laptop tomorrow. I will post updates when I can physically check it out.Also, this laptop is an older one, so no warranty or AppleCare on it. It is also running Leopard, but I doubt it is updated to the latest.
I'm looking for some information and possible repair tips for my cousins iMac G5 (First Gen) 1989. I don't know anything about mac's, I've always been a PC user. But, I recently fixed both my aunt's laptop and desktop (both pc), so my cousin asked if I would take a look at her mac, as well. Basically, when the iMac is turned on, the screen goes weird. It fills with a bunch of lines (both horizontal and vertical), some spanning the entire length of the screen, and some being only about half an inch long. The lines don't stay stable, they flicker and change positions every few seconds. Behind the lines, you can see the black screen with the apple on it.
It doesn't seem to get past this point though, it seems to freeze and never leave the apple screen, although the flickering lines continue to change. I tried jiggling and moving the power cord around, and whenever I moved it the lines on the screen seemed to change positions. I also tried taking hold of the sides of the monitor (machine? I have no idea what mac-speak for anything is) and very gently pressing and "twisting", and this changed the lines as well, at one point it turned to all vertical lines spanning the entire length of the screen. We opened it up to see if any wires were loose inside or anything, but there really weren't any exposed wires that I could see that I could even try to tighten/adjust. Right now it's not even usable.
2 vertical lines, running from top to bottom, have suddenly appeared on my screen. On a white back ground they appear blue and green. they have a wide space between them. I switched off and on but they are still there. Whats happening?
I have recently noticed two vertical lines (seem to be a lighter shade of display screen color) running top to bottom on my desktop. They stay on my display screen all of the time. This lovely old guy was purchased May 2006 but has every upgrade (except Lion....running Snow Leopard) and full component of memory...serves me well but I need to know if this is a sign I am losing my hardware.
Info: Imac with Intel Core Duo, Mac OS X (10.4.11), 512 MB memory 160GB
My 2008 Penryn White Macbook siplays vertical lines and or vertical grey/black bars on 60% of the display. This happens from when it is powered on until and including when you arrive at desktop. The space the lines occupy does not increase or shrink, they have covered the area from the moment the problem arose.
it is not the common line issue that a Tiger update solved since this Macbook came with Leopard pre-installed. The lines are still there with the hard drive removed and they are still there when I booted a live Ubuntu CD, so I have ruled out software being the cause. Also I have ruled out inverter because I would not be getting any backlighting.
So....
To me that leaves:
-The LCD display panel itself (although there is no physical damage and it has never been dropped)
-The display data cable that connects LCD to the logic board
I've got a 2006 17" iMac (serial # starts with QP) and it's developed several bright, vertical lines on the display. Been reading around and it appears that this is not an uncommon problem. Whether this is something that can be repaired.
My display has colored vertical lines on it and I can't get the computer to do anything. Powering it off and then on again the lines just come up again. This computer is about 2 months old so this shouldn't be happening.
My problem is a screen that is lit but grey, with vertical lines very faint in the background. when connected to a monitor all is well. I have replaced the screen with a second hand one from ebay and it is exactly the same. what is more likely- both screens are duff or is there something obvious i'm missing. i was given the ibook by a friend replaced the harddrive and gave it to my son and it worked for six weeks perfectly until the display suddenly went never to return.
I have a problem with the display of an iMac G5 20". It shows up as vertical lines of small squares.
If I change screen resolution, the display will look ok for about half a second, and then it comes back again. Anyone had seen this before? (This is does not look like the usual problem with iMac and thin vertical lines.)
The other day the screen started blinking randomly. It'll flicker for a few seconds and then go white with vertical grey lines for a few seconds. Then it will go back to normal. There doesn't seem to be a pattern to it. Sometimes it will go through that process for five minutes and then stop. Other times I can be working on it for hours and nothing will blink or act screwed up.
Since yesterday, my screen has been acting really wierd. Every few hours, the screen goes all fuzzy with a bunch of white lines on it, and it becomes completely unusable. It only happens for a few seconds each time (fortunately, it's fine right now), but it's kinda got me worried because I need to keep this computer for 2 more years before getting a new one, and I can't afford to fix it. I can't stop using it because I need it for school, so if it breaks, I'm completely screwed.
In the past month, my Macbook pro, which I have had since May 2009, has started to act very strange.
Sometimes when I watch videos online (collegehumor, youtube, etc.), or am just working on my laptop, the screen stops working. It goes mostly black, and a bunch of weird lines appear on the screen.
The system hasn't crashed or froze, since I can still see my mouse because one little line follows its movement, and the audio still works, and I can still Command + Q and exit out of programs.
I think the problem may have been that I slipped on the stairs one day holding my Macbook Pro and may have damaged the screen somehow, but I just want to know if this has happened to somebody else with their MBP, and what caused it?
I'm going on a day long driving trip with my kids later this week and I kludged together a good solution of bungee cords to hold my titanium PB to the back of a seat so I can play movies for them. I got a Sony car inverter that seems to output an appropriate amount of power for the PB. On a test drive around the block with the DVD running, the PB seemed to get pretty hot, but otherwise worked fine. Is there any reason why I shouldn't go ahead with this setup? Anything I'm likely to wreck?
These lines are 1cm apart one another, and are almost invisible, but their "flicking" it's really noticeable and quite annoying working as a graphic. It has less than 2 years but they say that the warranty it's over, even if by law it should be at least 2 years, it's obviously ah hardware problem, so I'm quite sure it's a display problem and probably should be replaced.

I just bought an eMac from an appliance recycing center. It works great except for the lines running down the screen well it's kind of more like shaky. It's a G4 800 mhz I took it through the rain to my truck to get it home. But even then it didn't get too wet.
My friend gave me his ibook 900mzh that was not displaying because he did not know how to fix it so I took a stab at it. I am not new to fixing computers as it is my profession but I'm new to Apples. Anyway, the first time I turned on the laptop the lcd displayed without any problems, every time after that it turns on randomly. After taking it apart about 3 times for various reasons and mistakes the laptop now displays every time I turn it on, but if I apply any type of pressure to the lower left side if the laptop the screen either goes black or gets small lines running through it. From what I have learned the only possible conclusion that I could come up with is the magnet that tells the ibook if it is open or closed has something wrong with it. It feels almost as if whenever there is any pressure around the hard drive the screen goes black. Any ideas, or tests I could do to fully determine the problem?
I've been having this problem for the last few weeks intermittently, and occurs whenever I bring my Macbook Pro (17 � 5,2 � 10.6.4) awake from sleep, or sometimes just when I switch it on.
It is a bit difficult to describe, so here is a picture:

I have to hard-reset the laptop to fix this each time...
Do I need to send it away for repairs or is this something that I could fix myself?
For the past few days, my screen has been going in and out of being entirely covered by 1px white lines that occasionally flicker blue or something. Like, when I'm typing (as I am now) if the window is positioned one pixel off, the blinking cursor won't appear (and on my black screensaver, it looks more like it's white/light grey because literally every other 1px line is white). Well, this morning it got weird again, but it hasn't gone back to normal!
I have a Mid-2007 Santa Rosa Macbook Pro, 2.4 Ghz Core 2 Duo- LED Screen, backlight works fine and if I turn it completely down ('off') the problem persists. I have Boot Camp installed, and the problem persists when booting into Windows as well.
I looked around and tried a few fixes to no avail (slept the screen, reset the PRAM, messed with the resolution a bit).
I took a screenshot and everything shows up normal. I had to finish a paper I was working on, and the screen was getting unbearable, so I tried plugging it into a mate's external lcd and the image came up completely fine, no vertical lines!
So, what could this be, and what could I do to fix it? Could this be the infamous problem with the Nvidia 8600GT M graphics card- so would I have to get the logic board repaired!? (UGH I hope not) Could it just be a connection issue? I did install a new hard drive, a new stick of memory, and Leopard, but that was months ago! Anything else I might be missing? and I hope this problem isn't too serious!
P.S.-on a side-note, has anybody done the upgrade to the latest firmware for the fans (SMC something)? Should I give that a try (or should I do it anyway, regardless of whether it could help)? When it was released, I heard of some bad experiences, so I stayed away.
iBook G4, OSX 10.4, has thin vertical lines appearing far right desktop...different colors. Four so far. Also, Safari keeps asking for keychain password but login password does not work and keychain utility won't allow any actions.
Related? This is a "refurbished" computer from Ebay (Tech Replay) and I don't have the system disks to start over.
When I start up my screen is filled with a load of bars made up of small vertical lines. After about 20 minutes they seem to stop appearing, although fragments of them remain on the desktop and dock. It' also runs really slowly at first.
Running OS x 10.5.8

I have tried disc utility Repair Disc (booted as a target disc) and Repair Disc Permissions
I have posted a screen grab here (it ain't pretty):[URL]
Whenever I watch videos or anything that moves I will see a line going through the video. Its not very visible, But its still there. Some say it could be a virus, others say hardware problems.
I move into my new place next week and find that the only source of internet will have to be through a wireless router. So now I am need of a Airport card. I have a 2005 iMac G5 (the generation right before the built-in iSight). I know that I need a Airport Extreme Card and an antenna, but I was wondering if somebody could fill me in on the exact part numbers I need for iMac. I've seen lots of different airport cards and do not want to buy the wrong one. If anyone can help me, that would be great.
Hi I'm connecting an external monitor to my macbook pro and am experiencing regular vertical lines throughout the external screen. I've tried DVI-D and VGA. I've tried changing resolutions. I have taken a screen shot of the monitor but this screen shot shows a clear image. Attached is a picture of what it looks like. Hard to spot as taken with my isight. (Ignore the cable hanging down).
