Title: Resistors before LCD FPC connector
Post by: Koen on November 26, 2016, 12:45:00 am

Hello,

   in multiple teardowns from both Dave and Mike, PCBs show resistors on LCD tracks before FPC connectors. Example : Seek Reveal Pro themal imager review & teardown (https://www.youtube.com/watch?v=mgaBAm_sRnk#t=18m20) at 18m20, components RN1 to RN5.
   What is their role and is there a commonly used value ?

Thank you very much,
Koen
