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

Liquid Crystal Display (LCD) screens use less energy and display a clearer picture than the Cathode Ray Tube (CRT) displays that preceded them. These new LCD screens now dominate the computer monitor market. From time to time, however, pixels can become stuck and a green line can display on the screen. Removing this line is sometimes possible without sending the screen to the manufacturer for expensive repair.
1.Locate the problem pixel. Display a true black image on your HP's monitor. You can do this by playing a DVD on your HP laptop, and pausing it on the black screen just before the movie starts. Once you bring up a black image on screen, the stuck or dead pixel should be visible.
2.Try applying direct pressure to the problematic pixel. After you've located it, turn off your laptop. Place a soft cloth or rag over the pixel to avoid damaging your screen. A soft chamois works well. Using the tip of a pen, apply gentle pressure to the pixel. You don't need to press hard, as too much pressure can crack or scratch your screen. While applying pressure, boot up your laptop. This should force the pixel to begin working properly.
3.Tap the pixel. With your Toshiba booted up and an image on the screen, gently tap the pixel with the rounded end of a pen cap. Tap hard just hard enough to see a small white flash on the screen. Tap your HP's screen until the pixel begins working properly.
4.Download a stuck pixel program. Several programs, including JScreenFix, UDPix and Pixel Protector, are available for download and can help fix a malfunctioning pixel. These programs display rapidly changing colors and images on your screen. The flashing colors and images can force the pixel to begin functioning properly.
5.Contact HP. If none of the above methods work, your screen may have a pixel that is truly dead. If that's the case, the only option is to replace the display completely. Contact HP customer support at www.hp.com to find an authorized repair service near you.
Technically, yes. It requires a level of expertise though. You would want to start by replacing the pixel panel. (Which is inside of the monitor and requires knowledge of monitor repair) - I would not recommend doing it yourself unless you are familiar with in-depth repair of components like this. Depending on the cost of the repair, it may be worth it to purchase a new monitor unfortunately. Sorry for the relatively bad news. Hope all works out! - Cheers!
You can try to reset the camera to factory defaults to see if this improves the monitor. You go to Menu and then left arrow to Reset and press Ok. Up arrow to Yes and Press ok this will put the camera back in factory default settings. If the screen still shows as pixelated, you might try to do a function of the camera called Pixel Mapping. Go to Menu and then right arrow to Setup then down arrow to Pixel Mapping - right arrow to Start and then the camera will try to repair the CCD processing chip inside the camera. If after this completes if the screen is still pixelated, then you want to send it to an Olympus service center for repair.
Please read the WHOLE of this guide before starting.Software Method
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.
Turn off your computer's monitor.
Get yourself a damp washcloth, so that you don't scratch your screen.
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.
Fold the washcloth to make sure you don't accidentally puncture it and scratch the screen.
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.
While applying pressure, turn on your computer and screen.
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.
Turn on the computer and LCD screen.
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).
Find a pen with a rounded end. A Sharpie marker with the cap on should be fine for this.
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.
Start tapping gently. Increase the pressure on the taps gradually for 5-10 taps until the pixel rights itself.
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.

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.
