Scrap-n-Repair: How to fix Kenwood DNX Headunit No Display/ No Power / Status LED RED

Описание к видео Scrap-n-Repair: How to fix Kenwood DNX Headunit No Display/ No Power / Status LED RED

This fix will work with any Kenwood head units with a detachable CPU board as shown in the video. Most models are from the DNX series.

The root cause is overheating due to a thermal issue between the CPU and the heatsink. Overheating makes the solder balls change their size and cause open solder or contact issues. A reflow / Reheating / Baking will fix the issue.

Hot Air gun Setting:
Temperature: 250 Degree Celsius
Airflow speed: Knob set at 6
FP-500 No-Clean Flux

Disclaimer: Perform this repair at your own risk touching any internal parts can cause electric shock!

NOTE: I do this pick electronic trash and repair as a hobby during my free time. Most of the units if not needed will be sold online.
