Frequent kernel panics due to thermalmonitord, missing sensors: TG0B

hello Jacob,

in iPhones and iPads, temperature monitoring is designed as a resistance control of elements named varistors. Their size is the same as other resistors around: 01005, 0402 etc. They can be easily confused. The processor, when executing the temperature control instruction, considers several to be more important and follows them more closely (hence the "panic" error).

The damage probably occurred while removing the motherboard (replace the battery needs to remove the motherboard or lift it up a bit - which is an even worse idea). In such cases, the iPad motherboard likes to crack on the surface, at the base of the electronic components.

If you are going to find and repair the damage yourself, get a good electronic diagram, locate the DZ elements (ex. DZ0000 - varistor number 0000) in the thermal control lines, codenamed: _NTC (ex. AP_NTC, BATTERY_NTC, RCAM_CAMERA_NTC, STROBE_MODULE_NTC etc.). Otherwise, find a good repair shop and confirm its competence in advance. The iPad is a difficult device to repair, designed in such cases only to be replaced.

Repair price may vary and many repair shops charging an extra $ 75-100 for screen removal (due to damage at this stage and having to pay for a new screen). In total, it will come to $ 150-300.
