SOURCE: finger print software causing blue screen of death

drivers for fingerprint software became corrupt. uninstall and reinstall of drivers along with doing a hardware reset (bios/security/fingerprint hardware) did the job.

SOURCE: finger print marks on the screen

you mean clean the screen ??
any solution designed to work with perspex or acrylic will be perfect. try "uvex" products or those designed for perspex motorcycle crash helmet visors.
i had a few rear projection tvs over the years and normal everyday household polish didnt do mine any harm at all.
also a damp cloth will remove fingerprints but will leave smears. so skip the washing stage and just use an everday household polish without beeswax in it ,cos that puts a waxy coating on it. stay away from any alchohol based products.and if in doubt try the uvex stuff

I am reading a book on my new Aura Kobo ereader, the print is too small, how do I get back to menu to change size of print?


No menu required. Just use two fingers on the screen and slide them apart. Be careful, it's easy to get very big, very quickly.
To get smaller slide two fingers together on the screen.

Just went to use my garmin 255w and screen is all garbled with a black mark and weird marks on screen. Is there anything I can do. Thanks


Looks like the screen is broken. Did it fall down? Did you carry it in a backpack and forgot about it?
If you turn it on and press with your finger on the screen. Does the mark move?

Hi there,

You just need to tap three fingers on your iphone at the same time. What happened was that you might accidentally placed three fingers on your iphone's screen when you grab it from your pocket or purse.

Hope this helps.

How do I clean the screen to clear finger prints.


You need a proper cleaning solution for the new flat panel screen. The best I have tried is Monster ScreenClean. This cleaner comes with a microfiber cloth and actually repels dust and fingerprint buildup. I use it on my big screen and it rarely needs cleaning now.I have used it for three years and works great. Hope this helps.

I have a brother MFC-8460N and I keep getting ink marks on my drum. I clean it good and try to print again and it goes back on the drum. It makes big lines on the page. What should I do?


check the drum cartridge for marks on it, if that dose not fix
is the toner cartridge genuine some remanufacted one are dodgie
the drum cartridge sould last approx 30,000 print outs
the worst case could be your fuser unit. only other option is to clean inside the machine. ps do not touch drum unit, drum
as it will duplicate finger prints and scratches.
