My NC-10 screen just went crazy. By applying light pressure on the screen I can get a normal screen, but it just goes crazy again. What is wrong and is it repairable? This happened relatively suddenly. It was working fine then the screen started to flutter then it went crazy all within 30-45 minutes.

You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp. To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight. It could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out, this is the most likely case. The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Tip: The max point reward for answering a question is 15.
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.
did you use an engine flushing agent ? if not try one, also you should be using a 10/40 semi synthetic oil for the age of car,then after refilling take revs upto 3000 for about 30 secs,(when hot)if that dont cure it then start looking at oil pump(more costly last)
Find a pen that has a rounded, dull end and get a slightly damp cloth to protect your screen.
Fold your cloth in two so that you do not puncture it accidentally. You don’t want to scratch your screen, do you?
Put the cloth in front of the stuck pixel and start applying slight pressure on it with your pen. Do not put pressure anywhere else than on the defective pixel, or you may break additional ones.
Continue applying pressure, and turn your monitor on.
Remove the pen from the screen, and voilà! The stuck pixel should be gone.
Be very careful doing this. The monitor is very fragile and too much pressure may cause more dead pixels. You can also just try it with your finger while the screen is on... just massage the area. NOT TOO MUCH PRESSURE! also try tapping that spot... if you see a little white color while you tap that is plenty of pressure. Let me know if that helps it. (This is only for LCD)
you might try and change the pcv valve, my car hand a similar problem in the summer and i never changed it. the pressure blew my cam seal and i was leaking oil like crazy. i dont know if it will fix it but they are cheap. i would give it a try.
I have the same problem, the s150 touch screen is pathetic, Got the same story from Strathfield Car Radio..it was normal and had it in for repairs twice when the screen went crazy with vertical lines, same fault both times. I went back to using my s50 and will sell the s150, it is a highly complex, very pretty lemon. They wont refund you or give map upgrades for inconvenience caused by their faulty product. To sum the s150 up. A truly Miserable experience. Rate it out of ten? its a minus. Graeme
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.
