This fix will work with any Kenwood head units with a detachable CPU board as shown in the video. Most models are from the DNX series.
The root cause is overheating due to a thermal issue between the CPU and the heatsink. Overheating makes the solder balls change their size and cause open…

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 😊
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
Amigo como te ubico? Tengo un problema parecido. Me ayudas en linea y yo te consigno!🙏🏽
Ok,so it worked for a couple of days,turned off and on a few times on it’s own,now it’s off permanently,only this time,when the security panel is removed the red light flashes 💁♂️
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 !!!!!👍👍👍👍
Great job done!!
On next videos – tell us which test pont voltages 😊❤
It works, thanks.
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?
It worked. I did exactly what you said in the video. Thanks.😊
Did excatly as in the video. Worked like a song. Many thanks from Germany!
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
Bro you are the best😂
btw what was the size of the thermal pad?
Was that 250F or 250C?
my kenwood dnx891 did this a couple years ago, didnt know this solution and just replaced daughterboard, fixed it, something else went wrong, now its just sitting. bought same model last year (another one), last month this new one got black screen, gonna try this
HOLY COW! THIS WORKED!!!
My DNX4230 boots up but just stays on Intelligent Motion screen and doesn't fully load, any ideas what could be causing that, Mitsubishi ASX, tried resetting from the red triangle and disconnected and reconnected cables but will just load to Intelligent Motion screen and stays on that screen
HI from Argentina. It works, same problem and it fixed it Thanks!
It looks like I have identical issue. Which no-clean flux do you use at 3:21?
It worked!!! Unbelievable! I just used a hair dryer and it took no more than 20 minutes, excluding cooling time! Thank you!
So I hit a bump. And my radio cut out… it had a flashing red light & will eject the disc… but no screen. Help?
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 https://youtu.be/zMSFZaZt9YM 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!
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?
I think I probably got mine to hot and destroyed it. It didn't work for me
I have a Red substance deposited on the motherboard what is it?
Hi, i have a DNX9990HD, i proceed with the Software Update and get an error. Now the don't go out from the Update Software. Somebody know what i have to do ?
👍 I couldn’t believe this would work, but to my surprise it did. Thanks very much for the tutorial.
I have same problem with my kenwood
Hi. The Kenwood head unit on my 2014 Subaru XV has no power. Is it possible for u to get it repaired for me? Are u in Malaysia by any chance? 😁
I have had to do this about 5 times over the years. Seems very random when it decides to die again. Just took a 500 mile trip, no problem. Go to work the next day, red screen.
How I connected the system outside the car
Fixed my unit just as prescribed! Thanks
thank you! – fixed mine up. used oven at 275 F for 10 minutes. Unbelievable that this same problem has hit me on Playstation, Kenwood car stereo, and two LG 65" TVs. Manufacturing problem?
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!
Very helpful video, this is how I did it and everything works again. Thanks
Just have one fixed!! Same problem, same procedure and it's back to life!!! Thanks again.
Thumbs up thousand times 👍👍👍👍
Who can I go to get this done for my 962HD? Please help. I had old factory radio put back in traded in the car. I still have Kenwood in my garage.
My unit had same symptoms. Followed video instruction and it worked.
Yeeehaa. Only problem cannot get any volume on radio or disc player….yet!
You said 250 c but what air flow speed did you use on hot air gun?
How does the reflow fix it? What does it actually do?
