Hot / Cold Fault Troubleshooting Methods

Contributed By: remingtoncountry1100

Hi, just wanted to share this 1) service technique to diagnose a failed component using the hot cold method. This video is aimed for those that are learning electronic servicing or expanding fault finding skills.  This radio had a receiver failure that was caused by a unstable component in the voltage control oscillator (VCO) stage.  It took less than 30 seconds to find the failed component.  This method can be used to fault find electronics that have aging components in mid voltage circuits.  I hope this video provides some value to someone out there.
