CB Radio Repair Log - Cobra 29 LX Fails to Power On

I wasn't planning on doing a video for this, but I wanted to show my brother what the nature of the issue with his radio was so I thought I would record it.

Cobra 29 LX Radio: amzn.to/2IVG3cg
Note: I couldn't find another RealTree Edition to post a link to, sorry, :-(
MFJ Dummy Load: amzn.to/2rWPQoN
Note: After this video I performed several tests such as leaving the radio powered on overnight and transmitting into the dummy load for 4 minutes straight to make sure that the jumper wire didn't get hot. Everything worked out just fine, :-)

Followed his repair on circut board with jumper wire on my 29lx camo and it repaired it!!! Great video thank you

Your a life saver, don't be so hard on your brother, I was transferring this radio over from my old truck. I setup the polarity correct the first time a watched as I plugged it up and the screen flickered a few times and shut off. Verified the wiring was good. Cobra built these to fail apparently. I found a lead hanging over another trace. Thanks for the info

Thanks for this video, This is exactly what happened to my 29 in exact place. Thanks again

ya I'm having the same problem, diode tested good,, but swapped it out anyways, swapped the cap even tho it looked good,,, and theres no apparent burns or melt downs, I'm lost

[@tomthumb1498]

Thank you very much for this video. I fixed fine in 10 minutes.

[@travishurd7619]

Thank you, I couldn't figure what was wrong with mine for a long time but I had the same problem

[@markrob9752]

Straight to the point

[@Mr.Jason1994]

Thanks you, this is exactly what was wrong with mine.

[@RC-Heli835]

When it's not an easy fix like this I guess you have to find the schematic and Trace power flow to the break point? I found a bad diode in a Cobra 29 and replaced it but it did not turn on. The cap beside it checked out fine so reinstalled it.

Hello hello Adam on the cobra 29lx how do you tighten the on and off switch it is wobbing. Thanks Mark.

[@gerowen]

If the whole switch is wobbling, pull the knobs and the faceplate off and you should see a nut threaded over the knob itself that holds is still. Just tighten that nut.

[@downtown_brown2254]

I just got the one I'm working on fixed, I I feel kind of stupid because its the Exact spot that it was in this video,,, but I didn't notice it until I blew it off with electronic spray... ..

[@alonzor91]
