touch screen won't respond

My touch screen will not register any touch. I have replaced the screen/digitizer TWICE and the mother board. What else is there that controls the screen? The cable gets replaced with the screen and the port with the motherboard. What else is there? The back and home button does work at the bottom of the screen. I have also done a hard reset and cleared the cache.

Is this a good question?

My S4 galaxy touch pad was not working either. I took off the back removed battery & sim ect and got Hair dryer and went over back for 5min and also the front screen on a mid heat setting for about 3min. .. It fixed it!. It Seems like I had moisture in between the digitizer and Glass ....I was using it in my SPA a few nights b4. Try A Hairdryer! !!!

Where are you getting the parts from? It seems unlikely, but you hear lots of stories of people getting two faulty parts in a row when they're buying replacements. I usually suggest giving it one more try with a part from a different seller to see if it will work.

Check out the parts that iFixit sells: https://www.ifixit.com/Store/Parts/Samsu...

Make sure to match your cell carrier to the part you're buying. You're looking for the "display assembly," which includes the digitizer.

Thanks Annette. I thought that too. Each display had different problems, first one had a dead spot in the center of the screen on occasion, second would not register a touch at all except for the home and back buttons at the bottom. I got both display/digitizers from the same eBay store. They had over 10,000 transactions with a 99.9% rating. They sent me the second one with no hassle when I told them the first one seemed to have a problem. Both were in original packaging unopened. I guess that is what I will try again with another company, possibly ifixit.

My S4 has almost the same problem....but only the bottom right part of the screen won't touch and the return and home buttons....but every things else works.. what do I do?

That sounds like two different problems. A faulty digitizer, and a faulty home button. Try replacing the display assembly (including digitizer) and that will include a new home button/home button cable. iFixit has some S4 parts here: https://www.ifixit.com/Store/Parts/Samsu...

Just replaced the digitizer/screen assembly for the third time. Seems to have corrected all of the problems. Thanks for your help.

some people have been saying that EVEN AFTER replacing the digitizer the phone's screen still isn't working so it's CLEARLY CAN'T be it. can't you people think of anything else????

I had same problem. Nothing worked plus can't remove the battery on my phone. Watched a video that says remove battery and hold down the on/off button for a minute to reset so thought why not. Wow it worked even though battery still in. Yay have all my contacts & diary back. So relieved!!!
