What is needed to fix iMac A1419 27" LCD Display Screen Skin Temperature Temp Sensor to LCD screen skin. Update (07/07/2018) I have replaced the screen and had to transfer the temperature sensor from the old to the new screen. I noticed that the sensor was attached to the rear of the screen with what looked like a bit of glue from a glue gun. Additionally it was covered with a piece of black tape. Is this special type of glue for heat transfer or can I use a glue gun, and can I use any tape to cover it.
Only the sensor part is thermally sensitive so you can use any heat resistant tape like: Polyimide Tape. Many off the shelf tapes adhesives breakdown from heat & time. Make sure the sensor body makes good contact to the mount point I would clean both surfaces and use a heat gun glue to hold it in place on the top just like how Apple did it.
Do you know what denomination value of the sensor ? Is it resistive? Trying to fix my iMac and multimeter measures that sensor as an open circuit. iMac Late 2012 ….
