Thread: Touch screen not working

Some years ago my parents gave me a tomtom go 730. I used it until one month ago when I decided to update the maps (first update ever,on advice of tomtom software) and when I turned on the device after the reboot, I noticed that the touch screen didn't work (completely). I found on the web some answers regarding a calibration problem; so I followed the steps posted in these topics with no success. Then I changed the screen and also after that the situation didn't change. Do you think it could be a firmware problem? I'd be grateful if you could give me a hand. Sorry for my bad english and thanks for your attention

I think it could be the Bootloader because this will controll all the hardware.
With your last update, I suppose you did a Navcore update too ?
When you did it could be quite possible that there was a file "system" in that Navcore
Any idea which Bootloader you have now and which before ?

Goodluck anyway

If you dare, open it and check the connector and cable, these things are so thin, be carefull
