Ok,so I had the red light of doom illuminate on my kenwood dnx 525 dab,so my friend and I followed your video to the T,and hey presto !!!! It works again !!!!! Wow !!!!!! Thankyou for the video and advice-It really does work !!!!!👍👍👍👍

Just want to thank you for your detailed video, Kenwood DNX4230DAB got the red tint screen of death last night and wouldn't power back on, was about to pull the trigger on buying a new headunit and came across your video after a quick search - headunit now back in car running like new, just want to say thanks and you have earned a sub. 🏆🥇😉

So took the unit back out,used a blow directional heat unit on the chips,only this time,@ 280 degrees and for 1 minute 20 seconds,all working again,let’s hope that has done the trick this time 😊

Just swapped out a dead DNX 4230DAB at the garage i work at for a customer and made sure to keep it all to one side, will definitely be giving this a go!

Did excatly as in the video. Worked like a song. Many thanks from Germany!

Just have one fixed!! Same problem, same procedure and it's back to life!!! Thanks again.

What can you replace the thermal pad with to help stop over heating? Thermal grizzlies thermal paste? Or does it have to be a thermal pad?

galing! 🙌🏻🙌🏻

So I hit a bump. And my radio cut out… it had a flashing red light & will eject the disc… but no screen. Help?

It works, thanks.

When you say "remove the SD card", how would you go about replacing that sd card within the daughter board? i see i can take mine out but is that something that can be purchased online or can i just get a new micro sd card and add the maps files needed to it and put that new card in that slot?

Hi, thank you for a great video... I've done the reflow exactly the same as your video on 3 Kenwood DNX4230DAB units and the procedure as worked, the units all work apart from when I load a CD the units lose power for a split second then restart but stay on the logo, BARBARIAN in this case, any idea on this please? It seems strange all 3 units have the same issue. Thank you, Jack

I think I probably got mine to hot and destroyed it. It didn't work for me

I can't thank you enough. It worked and your video was really clear. I didn't have a flux pen but wiped some normal flux around the chip using the end of zip tie. I used a normal heat gun but protected the plastic connector with the heat shield. Just did it for a minute like u said. I used a temperature gun to make sure it wasn't getting too hot. I used some silicone grease ontop of the chip when rebuilding to aid the heat transfer. My Dad used to use silicone grease on transister heat sinks back in the day when fixing TVs. Is that a special type or will any silicone grease do the job. Again thank you for making this video and sharing your knowledge

Thanks, this is great I need to try this. Can you recommend the flux pen you are using? Also, is the issue only the CPU - this video kzread.info/dash/bejne/rIGHqLyaitefibA.html is similar but advises to heat the whole board, and the chip named IC500 ? I am unsure if all board needs heat/flux/reflow - or just the main CPU as in your video? Many thanks!
