Frequently Asked Questions
Stuck pixels on LCD screens
A stuck pixel is a bright dot of colour most noticeable when the rest of the screen is black. Stuck pixels are fairly common on high resolution LCD screens. Stuck pixels sometimes start working again with time unless they appear black on a white background, these are known as dead pixels.
How do I check for stuck pixels?
JScreenFix will help fix stuck pixels on LCD screens. Most stuck pixels are repaired within 20 minutes. Some users have reported that JScreenFix can even fix dead pixels!
Unlike other solutions, JScreenFix works on each colour component individually in an un-coordinated fashion. By random on-off cycles at up to 60 times a second, pixels are fixed through resonance and repetition. This is more effective at repairing stuck pixels and is less stressful on the screen's power supply circuitry. The technique is also less likely to cause photosensitive epilepsy, a common problem when playing traditional pixel fixing videos. However, viewing the screen while running JScreenFix is not recommended.
Burn-in and image persistence
Screen burn-in often occurs on plasma screens if an area of the screen does not change for a long period of time. Patterns on such areas will still be noticeable when new images are displayed. For TV input, channel logos often burn into the screen. For digital signage systems, the problem can be even more severe where words can still be read months after they were originally displayed. This can also occur on LCD screens and is more correctly referred to as image persistence.
How do I check for screen burn-in?
JScreenFix can fix screen burn in on new plasma screens and remove LCD image persistence in between 6 and 48 hours.
Repair a screen using the JScreenFix applet
The JScreenFix Java applet helps fix stuck pixels on LCD screens and remove burn-in / image persistence by randomly switching on and off red, green and blue colour components very rapidly. The applet runs safely inside your web browser, does not require installation and works with Windows, Linux and Mac computers.
Other versions
You may need to download the Java Runtime Environment to launch JScreenFix applications. Java is free and is a useful addition to enhance your browsing experience.
This Java application processes the whole screen uniformly and is ideal for repairing burn-in as well as fixing multiple stuck pixels. The application uses fullscreen exclusive mode and will require approval of a security certificate. Please choose to trust the security certificate issued by Thawte Freemail Member to start the Java application. Two versions are available, webstart and standalone.

PixelProtector
PixelProtector is an essential tool for removing screen burn, correctly calibrating screens for optimal performance and gaining the best possible picture a unit has to offer. Any large screen television is an investment. Poor set-up and calibration can degrade the quality of a television’s image and severely threaten the life of the unit.
If you own a large plasma or LCD television and want to achieve optimum performance then PixelProtector is highly recommended!
More about JScreenFix
JScreenFix was developed as a special component for the Java Announcement Display System. JScreenFix is based on the observation that un tuned analog TV channels are particularly effective at fixing stuck pixels and removing burn-in. Every coloured cell on the screen is randomly turned on and off at up to 60 times a second by JScreenFix. The time between on and off is random which helps re-energise stuck pixels through resonance and repetition. The result is an increase in contrast and normalisation of colour levels in plasma and LCD screens. JScreenFix will also fix stuck pixels on LCD projectors but will not work on CRT screens.
JScreenFix can quickly fix faulty red, green and blue pixels visible on a black background. Additional success has been noted with repairing yellow, teal, purple and white pixels (sometimes these colour's revert to red green or blue before complete repair). Numerous users have reported that JScreenFix significantly improves picture quality on older LCD screens when left running for one hour or more.
Removing screen burn-in may require significantly more time, but a noticeable improvement should be visible after 6 hours.
