Samsung galaxy S3 touch screen not working

If the touch screen is not responding then you will need to take your Galaxy to either:
Your mobile phone providers store (If the phone is under manufacturers warranty you should be eligible for a free replacement)
A mobile phone shop - be prepared to pay somewhere around $250 USD. The Galaxy S3 touch screen , LCD and glass are all fused together and therefore have to be replaced as 1 single part. If your tech-savvy you can order the part for slightly less and do it yourself. Otherwise leave it to the pros! :)

I have touchsmart 300 and it is not touch sensitive can anyone help?


Reboot the PC and see if that takes care of the issue. All-in-One PC's tend to stay on all the time and do not get rebooted regularly and this could be causing the issue.

The touchscreens for HP use a sensor that looks at the front of the screen and scans for contact. If you look at the left, bottom and right of the screen, you will see the screen is recessed about 1/4". This is the glass that the touch sensor uses to "see" your finger inputs. If there is any dirt on this or if it is blocked in any way (tape, paper, etc.) the touch screen will be directly affected.

The link below covers the HP suggested troubleshooting of a touch screen issue for your model All-in-One. It covers the basics like keeping the screen clean, checking the OS to make sure the inputs options are enabled and how to further test this.

Replaced the broken glass front of my iphone 3GS. Everything looked fine, but the slider on the screen does not work... Did the replacement protocol all over again, but nope no slider. Any...

On touch screen phones like the iphone and N97, when replacing the screen there is a small ribbon attched to the back of the screen that connects to the main circuit board.This ribbon allows your phone to recognize you touching the screen and makes the screen work. Take the front cover back off and check that the connector is clean and dust free (on the new screen and on the phone) reconnect the ribbon and push down gently until its securely in place and re-attach the screen to your handset.

This should solve your problem and hope it helps please rate thanks

Hello, I got my LG Rumor Touch about 2 months ago, and I am having trouble with my touch calibration. There are many things wrong with the touch screen, and two examples are when i touch the numbers to...

It is hoped you bought this new because there is an issue with the digitizer(the glass plate that sits on top of your lcd screen and recognizes when you touch the screen). I've worked on tablets and phones for several years now and, unless you bought it new and with a warranty then your next step is to take it to a reputable phone repair service and have them replace the digitizer. If you hold the phone up flat and you can see ANY kind of separation between the LCD and the digitizer, then it will NOT function properly.

Sometimes you have to replace both the digitizer and the lcd as they are one piece.

Hope this helps.

Ceiling leaked into the plasma tv now has a black streak . can this be fixed

Hi my name is Eric,
I hope I can help you with your issue ,
Well you could take it apart and see, most plasmas have a glass front with a screen behind it. If you take the screen out you could clean the glass if thats where the black is. This job is about 2 hours on most plasmas.
If your TV is an LCD then there usually is no glass, tough the front and check. in that case you'd need a new screen 
If I have helped you with your issue please click accept.
If you have more questions you can still respond
I will reply asap
