Bricked Kenwood DNX. Cheap fix.
Вставка

- Really simple and cheap fix for this non working Kenwood DNX690HD. Cheap as in no money was spent. Well, maybe a little on electricity. Nothing was working anymore. No navigation, no radio, no bluetooth or phone. Completely dead.
I understand this is a frequent problem with Kenwood DNX series headunits. It might be a design flaw, a cooling problem for the chip sets inside, lack of good airflow... not sure what.
I watched a few videos explaining how to reflow the chipset and essentially fix the problem.
Use caution in this case. Do it at your own risk.
I would advise those who want to do it to start warming up the board and the chip slowly. Start at 5-6 inches above the board and gradually move the blower lower in order to prevent a thermal shock and have those components cracked. In my case it is a Toshiba chip.

This worked like a charm for me. I have a soldering/reflow station and used the hot air at 240c just on the main chip for about 30 seconds. Everything started working after that.
Just finished fixing my stereo thanks to this video!
IT WORKED!! I had a different model which made it was tough to get into but after that it all looked similar enough to follow your directions. I was absolutely not in the mood to spend 700 bucks on another one. Its been on the test bench for 3 days and all is good enough to go back on the truck.
I had this same problem with my kenwood dnx571hd, gave this a shot and it worked. Amazed.
I have to do this multiple times a year for mine and I have the exact same model as you.
Gracias por compartir excelente información, mi KENWOOD DNX890HD tenía más de dos años sin funcionar instalado en el vehículo, adicional tenía otro del mismo modelo dañado por la misma falla y ambos ahora funcionan a la perfección, siempre me comentaron que la falla era la memoria Empro. Gracias.... Gracias, espero que sigas brindando excelente información técnica como estas
This works!! I bought this exact radio on fb marketplace the like an idiot I took his word for it that it worked well after taking it apart and heating up the board it worked!!
Great video !
I tried a hair dryer.. didn’t get it hot enough so went and bought a heat gun.. and heated up the board for like 5 minutes put everything back together boom worked again! Also did the same thing u did and left the disk tray out! I got the radio for free off a buddy and was about to throw it away thank you ! Great video
really?
Still working??
En verdad funciona , mi radio tenía ese problema , muchas gracias , me salvé de comprar otro !!! 🙌
Thanks mate this actually worked, used a hair dryer first, no luck. Then i used my toaster ,holding the corner with pliers , Ding" and Done. You just saved me some big bucks.
Still working?
@@troylollysaf9311 hi bud , lasts about 6 months then you have to do it again. bout 2 weeks ago did it again but no luck this time.
@@doobiescoot554I bake mine in the oven for 5 mins. Nothing like fresh baked cpu board! lol
Hey Bud thanks a ton! DNX571HD reflow worked for me
I went for about 20 seconds on the top side of the ic500 chip only with my heat gun and...Bingo! I already had my son looking for a new radio because I figured there was no chance this would actually work. So happy to be wrong. Thanks for posting.
Did the reflow fix on my home screen looping dnx692 this morning and it WORKED. Wow tha ks for the info.....save me 700 for a new stereo
This worked for me awesome thanks for the video
I just fixed mines and I watched that video last year but did not have a heat gun I used a blow dryer no go. Took it out to day and bought a heat gun and it was a success and I didnt put in my cd player to
THANKS FOR THE SHOUT OUT!
Does anyone recommend i buy this?
Woot I fixed it following this
I just tried this out on a kenwood dnx771hd unit and it is back up and working again. I actually did it 3 times as i wasn't sure how long or hot it should get. The working combo for me was using the high setting on a 1400w heat gun for 1 minute. I was about 4 - 5 inches away from the chip and moved it in a small circle over the top of it.
Hi Connor! I did the reflow once and the unit got the logo screen but no initial/menu screen (it was with black screen, no logo, nothing). Should I try the reflow again??
@@MrFreevo I'm no expert. But I would try again. The Second time I did it then fan on the back started working but the whole radio wouldn't turn on yet.
Still working now?
thank you
I have an older one and its very buggy, its as if the internal memory is bad or corrupt as it shows missing icon place holders for the most basic things, like arrows, and back buttons, just very low level icons in the GPS navigation screens only. I pulled the internal uSD card and placed it in a Windows PC (linux could not even mount the 2nd partition) and it found 2 partitions on the uSD card (on the board) one GARMIN folder was 31k, other GARMIN was 3.9GB. weird that it had 2 GARMIN folders, one on each partition? I used windows to scan for problems on the partitions and it was able to 'fix' both (?) and when I put the unit back together, it was much faster booting. Could be that the card slot area you mentioned was cold solder joint or the uSD card became corrupt? I put the other uSD the Garmin Express after initializing it in the unit and it said it had a map update. Downloaded it, and put it back in the unit. It came up, then my battery died. Took card back out and put it back into Garmin Express and now it fonds 3 more updates......load them. Take out, put back into Garmin Express and it has another mad download? Seems to not register the map update until you put it back into the DNX and it puts some sort of tag on it. Interesting decks. Keep the CD deck in there, it will help pull air over the heatsink at a higher velocity for better air cooling. You never know when youll spot that CD only title at the thrift shop for a buck.
great stuff
where i can buy the main power of the dnx6190hd,,the mine is bad
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 have one Wich the Bluetooth quit working and the module doesn't show up in the version info
Does anyone recommend i buy this?
any time you do a reflow, use a clear flux if possible on the solder joints in question. also, POST YOUR TIME AND DISTANCE OF HEAT SOURCE!!! so may of these say "reflow it"...well,, that could mean warming it up for 30 seconds or really cooking it at over 220C for 80 seconds and maxing at 250C. that is the official reflow temperature for lead free solder using a heat source. I just picked up one and will post results, crossing my fingers!
Hey mate, worked a treat, thanks for posting! Can you comment if the unit is still running, or how long the fix lasted for you?
Cheers
It worked for a while and I had to do it again. Using the hair dryer is probably not the smartest thing to do. I ended up replacing the unit.
@@dixy2k where did youbget a replacement daughter board from?
@@thatmodshop7160 I did not.
Daughter board is around 150 i saw somewhere
@@dixy2k hair dryer not hot enough
So you needed to improve on his method. Good job 👏
My dnx have similar issue but power after connection or reset red led lit a while and then goes down. Someone had the same behavior? Or my problem is different damage.
It could be a different issue. Mine showed it got power, but would not do anything or sometimes it would glitch a lot.
@@dixy2k I afraid it's different :/
@Womb Raider Unfortunately not
@Womb Raider thx for information. I tried but in mine it didn’t work. Maybe to short… I’ll try one more time
I did this worked great for 2 weeks im bak to not working any suggestions
It could be a different issue all together. I cannot ever say this procedure will cure every electronic problem. It would be absurd to say that.
Hola , me gustaría saber si mi pantalla kenwood dnx 9280 bt tiene reparación, un dí por la mañana iba con la radio puesta y pare el coche y la radio funcionaba , cuando volví por la tarde ya no funcionaba, se reinicia solo , se apaga y se enciende , ya no funcionaba por la tarde , es una pantalla que reclinable , alguien me puede decir que puede ser?
Last time I buy Kenwood nav.
Do they have fuses?
Yes.
How many of you guys did this reflow and it stop working weeks or months later?
El mío no funciona el touch. Tendrás alguna solución
No.
How long do you have to reflow?
I guess it depends on your heat source. Since I used a hair blowdryer I took a lot of time to compensate for lack of high temperature. I think I did it for 10-15 minutes total.
@@dixy2k The first time I tried and I can't turn on, now I will try again with the heat gun, but really how long is it necessary to heat the toshiba plate ...
@@dixy2k exactly does it have to be on the toshiba part or all?
@@NEOVVLad97 I did it on both sides just like the guy I referenced in my video did. You might want to do a few minutes on both sides using a heat gun since it puts out a lot more heat than a blow dryer.
It's also possible you might have a different problem if the heat did not take care of the issue you have with your unit. It's always a good idea to check with a repair specialist.
Do you have a Vid of you actually using heat gun on Board thanks 👍🏻
No. I used a hair dryer since I got no heat gun.
I have to do this every 2-3 months. It’s sucks. I need to stop being cheap and buy a new radio
So funny I came across this video I have the same radio and the samething is happening red light black screen
"Your mileage may vary"
Does anyone recommend i buy this?
Dan
Do you fix this for money?
No. It was my own radio.
Would you be interested in fixing my own similar radio and I will kindly pay you?
@@stitrooper1219 No. If you cannot unscrew a few screws and use a hair drier try to contact the guy I referenced in my video maybe he can help.
@@dixy2k ok, thanks!
OMG SHOW HOW TO TAKE THE WIRES OUT ................
Which ones?
@@dixy2k I figured out how to do it. I was talking about the Ribbon Cable Connectors...i was so frustrated and didn't want to break it.
