[TG11] es127 touch screen failure

[Brian_Kohl]

I have exactly this issue. I have completed suggestion 1 and checked the battery supply (fine) and so far no change.

Mine also seems related to heat, but can also occur at night when cool. I have put in fans and increased air flow but that hasn't helped.

Most of the time I can also operate it from the iPad App - touch works on the iPad and the screen reacts but it will not function from the screen directly.

It started after I did a software upgrade to the new 'lighthouse' os, but I do not know if it is related to that or not.

It is related to how much it is being 'used' - it will almost always happen if I try and enter a waypoing via lat/long for example. If I don't touch anything it will generally keep functioning for quite a few hours; however, even then it will eventually start zooming in to the max zoom and will sit there and refuse to accept input.

How was your issue resolved?
