First separate no startup response from a charging indication followed by a startup problem. Those are different observations.

Does your version recharge?

Check the full model and the power section of its instructions. The current MY139 and MY135 catalog references use rechargeable batteries; CN69 uses wall power. An older version or a similar-looking body may use a different arrangement.

For a version with replaceable batteries, use only the type and orientation stated in its guide. Do not open the housing to find out whether an internal battery is replaceable.

Check the visible power path

  1. Read the labels. Compare the device’s power requirements with the power accessory you are using.
  2. Inspect while disconnected. Look for a damaged cable, loose connector or visible moisture. Do not insert anything into the port.
  3. Use the documented connection procedure. Substitute a cable or adapter only when it is confirmed compatible.

Charging duration, completion indicators and use while connected must come from the matching guide. A USB connector alone does not answer those questions.

What happens when connected?

ObservationInclude in your request
No visible responsePower source used, accessory label and whether the normal startup method produces any response.
Light or display appearsExact symbol or color, steady or flashing, and whether it changes.
Starts only while connectedWhat happens when the connection is removed, if already observed.
Problem began after a changeWhich cable, adapter or battery changed and when.

“USB adapter, label reads …; light flashes twice when connected” is more informative than “I tried a charger.”

If there is heat or damage

Stop use and charging if you observe swelling, smoke, a burning smell or damaged wiring. Do not repeat the event for a recording or open the housing for a repair. Use damage guidance for the next step.
