Tomtom my tomtom go 910 screen wont work

Well i am writing this wile I am trying this out...
I have a TomTom Go 910 that has a RED CROSS FLASHING on the bottom corner, what I have found is that if you have backed up your TomTom Go i maybe able to reset the TomTom Go on my computer but if you havent you may have to find on try finding one on google but i have a TomTom Go 910 you can download the 910 on http://rapiddigger.com/download/backup-go-910-rar-9110176/.

after you found the back-up you can connect your TomTom Go to your computer using the USB provided from your TomTom Go, replace the doggie file with the new one, then this should change it back to the FIRST update given...

(WARNING >> PLEASE scan the file befor you put it in your TomTom Go it might contain a very very evil virus<< WARNING)

This site has instructions how to change the battery

If the LCD backlight is gone theres no choice but to replace the whole screen ( OR it could be the LCD lamp driver circuit on the circuit board ) . It's not economical to purchase a new screen but it is possible to purchase a defunct 910 , typicaly off ebay and use the screen from it . ( ensure you are buying a tomtom with a good intact screen ) . Changing the screen is tricky and fiddly but someone with general electronics knowledge should'nt find it difficult. You also need the special "star" drivers for the screws ( sometimes known as ' torxs ' ). If you are inexperienced with this sort of work then its best not to attempt it. There are companies advertising that can do this type of work for you and especialy in UK......... Good luck.

interal battery maybe

Complain to Tom Tom ,you may have a lemon,look for law suit soon

stevi at the back of your tom tom where your windscreen dock goes there is a small rubber bumper if you look to the right and down you will see the reset button it is a small hole above the dock socket. sandy

I discovered that there was a file on the 910 called CLMDATA which was corrupt. When I deleted this in Windows explorer, the unit started up and worked OK. This file is recreated when the unit starts up

Try a reset. It worked for me with the same problem.
