Question about Apple Cinema HD 30" LCD Monitor

1 Answer

Does any one know where I can get a Service / repair manual?

My monitor when turned on for several minutes has pixels that start freaking out in patterns and I wanted to take a look and see if there is anything obvious. (also for curiosities sake). I am pretty sure that I will have to remove the white side plastic pieces with suction cups but I am not sure. Can anyone help? thanks Rob

Re: Does any one know where I can get a Service / repair...

Have you reconnected the dvi on the rear of the machine? I would test the connection and reset the graphics card before opening the display.

keep me posted.

I have an HP L2208w monitor which has been ok for the last two years. Suddenly, it started to display patches of different colours. Also vertical and horizontal colours appear across some pf these patches....

hi steven_katas

Im thinking that this maybe a LCD panel problem (dead pixels) already. some LCD panels last for 2-3 years depending on usage. even if you haven't dropped it or anything the LCD panel's pixels ten to give way slowly or die down since these pixels are like bulbs. here's what you can do. Try connecting a different cable from your monitor to your computer if the issue is still the same, try connecting a different computer or maybe a laptop to your monitor just to eliminate the probability that it can be a cable or a video card problem.
If you have already connected a new computer say a laptop and it is still the same it might already be a hardware problem with your monitor and might need you to bring it to the service center for repair.

Hope this helps please let me know

I have a red dot on a Coby TF-TV2001. What can I do to repair this?

If you mean you have a pixel that is stuck on and is always red, there's nothing you can do. The only cure is to replace the display. LCD displays sometimes will have a pixel (sometimes several pixels) that doesn't work properly. The manufacturers know this, and as long the display falls within their specifications for what's acceptable, they don't see anything wrong. These specs include the total number of bad pixels, the number of bad pixels that can be clustered together, and where they can be on the display. If you have just one or only a few bad spots, they won't do anything for you. If other problems develop, such as a whole row or column goes bad or a section of the display fails, then you can see about having them fix it if the warranty is still in effect.

Monitor is taking forever to load

Thats all normal... sounds like a signal interface problem, You may be able to fix it, but you will need a soldering iron, solder, a meter, the service manual & time, First step get a service manual, then check if your power supply voltages are correct and work out from there. It is NOT easy, I have been doing this all for over 30 years and never the same fault twice. professionally I recommend a new one, or why not take it in for repair, ask for a "Quote" for repair, and then you can make an informed decision as to repair or replace...

Screen goes pink and green starting with a few pixels

Best thing to do, try a different known working monitor to hook up to the computer. If the screen works and doesn't change colors then you know its the original monitor that is bad.

If you hook up the known working monitor and the same problem happens then you know its the video card that is bad and the video card would have to be replaced.

Monitor image flashes off and on

Sounds like you've done all the trouble shooting. If you just need that extra nudge, I would agree... it sounds like you'll be needing to shop for a new monitor.

Dead pixel

Please read the WHOLE of this guide before starting. Software Method
  1. Try running pixel fixing software. Stuck pixels can often be re-energized by rapidly turning them on and off. If this fails, complete the following steps.

Pressure Method
  1. Turn off your computer's monitor.
  2. Get yourself a damp washcloth, so that you don't scratch your screen.
  3. Take a household pen, pencil, screwdriver, or some other sort of instrument with a focused, but relatively dull, point. A very good tool would be a PDA stylus.
  4. Fold the washcloth to make sure you don't accidentally puncture it and scratch the screen.
  5. Apply pressure through the folded washcloth with the instrument to exactly where the stuck pixel is. Try not to put pressure anywhere else, as this may make more stuck pixels.
  6. While applying pressure, turn on your computer and screen.
  7. Remove pressure and the stuck pixel should be gone. This works as the liquid in the liquid crystal has not spread into each little pixel. This liquid is used with the backlight on your monitor, allowing different amounts of light through, which creates the different colors.

Tapping Method
  1. Turn on the computer and LCD screen.
  2. Display a black image, which will show the stuck pixel very clearly against the background. (It is very important that you are showing a black image and not just a blank signal, as you need the backlighting of the LCD to be illuminating the back of the panel).
  3. Find a pen with a rounded end. A Sharpie marker with the cap on should be fine for this.
  4. Use the rounded end of the pen to gently tap where the stuck pixel is - not too hard to start with, just enough to see a quick white glow under the point of contact. If you didn't see a white glow, then you didn't tap hard enough, so use just slightly more pressure this time.
  5. Start tapping gently. Increase the pressure on the taps gradually for 5-10 taps until the pixel rights itself.
  6. Display a white image (an empty text document is good for this) to verify that you haven't accidentally caused more damage than you fixed.

  • If the pressure and tapping don't work directly on the stuck pixel, start moving outward around the stuck pixel. If you see the pixel flicker while doing this then you know where you can focus the pressure and tapping techniques rather than directly on the pixel.
  • Many people report success with this technique but these instructions won't work in every case. It may take a few attempts to make sure you are pressing exactly on the stuck pixel.
  • These instructions will fix "stuck" pixels, not "dead" ones. Dead pixels appear black while stuck pixels can be one constant color like red, blue or green.
  • An alternative, but similar technique involves gently massaging the stuck pixel with a warm damp (not wet) soft cloth.
  • Alternative technique to tapping: Using a rounded pencil eraser, push with moderate pressure into screen at stuck pixel.
  • If these instructions don't work, you can hopefully get the monitor replaced through your manufacturer. If your monitor falls under the specifications of replacement, get in contact with the manufacturer to set up replacement plans.

  • Do not attempt to open the monitor as it will void the warranty and the manufacturer will not replace it.
  • Make sure you don't get any electrical equipment wet or it may break.
  • Some people claim that touching the screen can cause more pixels to become stuck, although this has not been proven.
  • Be prepared to suffer a complete loss; you may crack the glass when tapping or putting pressure on an LCD assembly.

Red pixels on the Srceen

Dead or stuck pixels are not uncommon in LCD displays, and the less you pay, the more likely it is to happen (as a general rule) Most manufacturers will a dead pixel warranty, ranging from 7 days to lifetime.

Read your warranty carefully, and speak to the place where you bought your display.

I hope that helps, if you have any further problems, please add them ass comments to this question. If I have been able to answer your question (or not) please click on one of the ratings buttons to let everyone know how I did.

Monitor goes blurry, colours/pixels start shaking across screen

Do you have your screen saver enabled, i so turn it off and se if it still does it. Secondly boot your pc in safe mode(pressing F8) on boot up and select start windows in safe mode. See if the monitor still does it, if so a monitor fault or loose/faulty vga lead. If it is ok then your graphics driver may be corrupt and need re installing.
