How can i change apple iPod Touch 4 4th Gen Digitizer

Well, if you put it in a freezer at all, I wouldn't expect it to even function properly... ever.

But regardless, you can try pressing harder. If it still doesn't work, the digitizer might not be recognizing the bottom half of the screen from sustaining too much damage.

depends on the specific iPod touch model you have....
there are 5 generations of iPod touch!
- for instance the iPod touch 3rd gen. can install only iOS 5.1.1 whereas the iPod touch 4th gen. can use iOS 6.1.6 as the latest iOS.

Either you have purchased a defective digitizer or the connection from the digitizer to the logic board are not contacting as they should be. Remove the new digitizer and check all the teeth (connections on both sides) and see if any are bent or missing.

iPod Touch 4th Generation:
iPod Touch 4th Generation: Heat the surrounding edges of the iPod for 30 seconds
Begin at the bottom corner...used a straight blade to pry the glass up slowly; the LCD will come with it since they are fused together.
When you get closer to the top be very careful since the wifi cable is normally sticking to the glass. If it is use a small screw driver to detach it from the glass. The wifi cable is on the opposite side of the power button.
There is one flex cable (LCD) that can be removed; just a slight twist and it should pop off easily.
The other flex cable (Digitizer) is under the logic board and since you'd be replacing it you can cut this flex cable to work with more ease.
Remove the eight screws on the metal plate.
Remove the metal cover over the camera...screw driver on the very edge and pop up...do not use much force or dig at it since it would be very easy to destroy the camera.
To remove the metal plate that covers the batter: bottom left corner... dig your screw driver in (shallow) then push through horizontally until you reach the edge and lift the end of the screw driver upwards...using this method will allow the speaker to stay in place and the metal plate to separate.
Remove the top three screws
Put a screw driver between the logic board and the power flex cable as you gently lift the logic board up on that side...this method will ensure you don't rip the POWER flex cable
Do not lift aggressively...both cameras must be lifted gently, the adhesive is not that strong but there are some there.
The power and volume flex cable connection to the logic board is near the volume buttons, be extremely careful not to damage the connection when lifting the logic board.
Remove the copper tape surrounding the connection for the digitizer and install new digitizer.
Follow steps in reverse.
Good Luck

ipod nano 6? The digitizer has gone bad more than likely.

The digitizer is connected by carefully pressing the end of the ribbon down onto the main board. You will feel a slight click as the connector engages.

You have to be sure to line-up the two halves of the connector just right before gently pressing down.

Hopefully you haven't damaged the ribbon cable.

I've replaced the digitizer 3 times on my 2nd generation iPod Touch and it's VERY easy to rip that ribbon.

Also, be sure to remove the protective, clear membrane from the inside and outside of the digitizer or your have to live with a blurry display until you replace it again.

Sounds like the digitizer for teh screen (the digitizer is what recognizes your finger touching the touch screen) needs to be replaced. It is a bit common with the iPhone and iPod Touch.

Most likely it is a burnt resistor, or your digitizer was bad/faulty. Try taking it off and using conductive spray (Without lube...No pun intended) but one with lube can ruin the digitizer. make sure not to get any overspray on anything but the conductors.
