sensor does not work after hitting tablet Z

[mariofm]

What to do? fell at an angle plate - stopped working sensor. Case-warranty and repair costs money unreal. Someone tell me - what can I do?

If its a hardware issue you will have to take it to a Sony repair center,  you could DIY, which will be cheaper but will void your warranty

if repairs do yourself, what you need to look firstly ?

The first thing I would do is to do a factory reset and/or reinstall the software with SUS or PCC, but I don't quite understand which sensor you are referring to, if you meant to say the Digitizer/touchscreen then you will have to either pay Sony or buy the piece online and install it yourself 

Update Service (SUS)

PC Companion (PCC)

Bridge (for Mac)

 touchscreen (digitizer) is very expensive and I did not even beat it, so I thought that the incidence could move something. I can fix it yourself, just do not know what to see and I can not find anyone who would have faced a similar problem

Have you contacted your local Sony?

[mariofm]

yet, but the case does not guarantee

I'm out of suggestions
