Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This was announced several months ago (March 2021) to allow our members ample time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.

  1. No, not the KX131, but another pcb cam. I thought I had blown that cam and I was in a rather bad mood for a day, when I decided to study the design of it in order to repair it. I`m a electro engineer, so I guess that help me abit :)

    I studied the parts on the cam and found the voltage regulator. If a parts is caled ex: LM7405, just type it in google and see what you find. The voltage regulator in my pcb camera was SMD, e.g a very little voltage regulator. I soldered it of and replaced it with a standard size voltage regulator with some leads, since i didnt have the SMD regulator at hand.

    The voltage regulator, often a tre pin device: Ground, voltage in and voltage out. It is often located nearby supply leads.

    It is worth a try. What do you have to loose :) A first step can be to hook it up to supply voltage and measure voltages across the voltage regulator.

    You mean you actually repaired a KX131 V-reg? Ok I admit it.. I am one of those who blew a KX131 by accidentally feeding it 12 volts on my multi-voltage supplier and camera mount. Do you have anymore info on how I can find the V-reg on the KX131 so I can experiment and repair this?
  2. Hello,

    Probably, the voltage regulator is blown.

    This is a simple device. If you are good in soldering, you can solder it off and replace it with a new one. If you are luck, this is the only component that is broken. Saved me one time :)


    Get the datasheet for the blown component and study it

    Look for defect components on the pcb and try to replace.

    A KX-131 camera (not mine, thank goodness) was subjected to 12VDC rather than 5VDC. This of course killed it. By chance has anyone around here done this and successfully fixed the carnage? For example, is there a hidden SMD protection fuse in it like the old CX-161?
