    en.wikipedia.org/wiki/List_of_LED_failure_modes

    Reverse bias: Although the LED is based on a diode junction and is nominally a rectifier, the reverse-breakdown mode for some types can occur at very low voltages and essentially any excess reverse bias can cause immediate degradation, and may lead to vastly accelerated failure. 5 V is a typical maximum reverse bias voltage specification for ...

    This flickering can cause problems for some individuals with light sensitivity [1] and are associated with headaches and eyestrain. Such lamps are listed as problematic for some individuals with autism, epilepsy, [2] lupus, [3] chronic fatigue syndrome, Lyme disease, [4] and vertigo. [5]

    Despite being regarded as one of the most reliable diesel engines ever put in a light-duty truck, [6] [7] the engine had its own issues. A common failure point was the camshaft position sensor (CPS). The failure of this sensor would cause a no-start condition or a stall while running.

    en.wikipedia.org/wiki/Fluorescent_lamp

    Fluorescent lamps with magnetic ballasts flicker at a normally unnoticeable frequency of 100 or 120 Hz and this flickering can cause problems for some individuals with light sensitivity; [69] they are listed as problematic for some individuals with autism, epilepsy, [70] lupus, [71] chronic fatigue syndrome, Lyme disease, [72] and vertigo. [73]

  6. Electrical fault - Wikipedia

    en.wikipedia.org/wiki/Electrical_fault

    Overhead power lines are easiest to diagnose since the problem is usually obvious, e.g., a tree has fallen across the line, or a utility pole is broken and the conductors are lying on the ground. Locating faults in a cable system can be done either with the circuit de-energized, or in some cases, with the circuit under power.

  7. Emergency service response codes - Wikipedia

    en.wikipedia.org/wiki/Emergency_service_response...

    Code 1: A time critical case with a lights and sirens ambulance response. An example is a cardiac arrest or serious traffic accident. Code 2: An acute but non-time critical response. The ambulance does not use lights and sirens to respond. An example of this response code is a broken leg. Code 3: A non-urgent routine case. These include cases ...

    Until December 13, 2021, the official cause of the problem was not revealed by Microsoft, leading third parties to make many different theories about what the exact cause of the problem was. Electronics industry newspaper EE Times reported that the problems may have started in the graphics chip.

  9. Check engine light - Wikipedia

    en.wikipedia.org/wiki/Check_engine_light

    A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).
