Discussion Overview

The discussion revolves around the effects of cooling electronics, specifically whether placing a malfunctioning Amazon Fire TV device in the fridge can temporarily restore its functionality. Participants explore the underlying mechanisms, potential risks, and alternative cooling methods, while also discussing the longevity and maintenance of electronic devices.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants suggest that cooling electronics may reduce semiconductor leakage currents, potentially restoring functionality.
  • Others warn about the risks of condensation forming on circuit boards when electronics are cooled, which could lead to further damage.
  • One participant notes that their device had previously worked after being unplugged for a few days, raising questions about the role of heat in its failure.
  • Concerns are raised about the safety of using a new device after cooling the old one, with some suggesting that it could damage the television if moisture is present.
  • Participants discuss alternative cooling methods, such as using a fan instead of refrigeration, to avoid risks associated with condensation.
  • There is mention of historical practices in electronics repair, such as using freezer spray, and the evolution of repairability in modern devices.
  • One participant questions whether unplugging a new device when not in use would extend its lifespan, while others discuss the impact of temperature swings on integrated circuits.

Areas of Agreement / Disagreement

Participants express a range of views on the effectiveness and safety of cooling electronics, with no consensus on whether coldness definitively fixes electronics or if other factors are at play. The discussion remains unresolved regarding the best practices for maintaining electronic devices.

Contextual Notes

Participants highlight various assumptions, such as the impact of humidity and temperature on electronic components, and the potential for internal moisture to cause damage. There is also mention of the limitations of modern electronics in terms of repairability compared to older models.

Who May Find This Useful

This discussion may be of interest to electronics enthusiasts, repair technicians, and consumers curious about the maintenance and longevity of electronic devices.

IIRC when Li batteries are deeply discharged they WILL NOT accept a charge.

Ahh, found it! There is a built-in protection circuit.

So the link above shows the absence of "boost" circuitry intended for revival of deeply discharged battery is common in mobile chargers. Therefore, more likelihood of "poorly designed charging controller" as diagnosis of initial problem.

Coldness fixes electronics? No way - what fixes electronics is a good hard slap! (experience from 15 years as a part-time electronics serviceman).

A hard slap to the top of the electronics enclosure actually helped vacuum tube devices. Apparently the jolt helped seat pins loosened by normal on/hot off/cold cycles. This was also when we waited for electronics to "warm up".
