hi, the screen wont respond to touch anymore..any ideas what is happening..it is only 3 weeks old (it is zenithink ). any suggestions most welcome thanks in advance paul
If you mean blue led on with nothing on screen. I took the back off which is easy,just use small pin in the holes on left side remove back, remove battery lead undo all screws that hold board down then their should be four screws holding down screen take these out.now replace battery lead the screen should liteup in your hands. This worked on mine I hope it works on yours
1) have you tried the external reset switch, on my zenithink zt-180 its a hole small enough for a paper clip
