Kenwood double din black screen repair

- Are you having issues with a kenwood radio where you only get the red power LED but the radio will not turn on? Even after resetting the unit? The common issue is the daughter board in these units with the processor chips. Since they are no longer available and the radios are past warranty, here is how to fix the black screen problem.
I bought a kenwood DXN 690HD at a yard sale for 10 bucks. I wasn’t expecting much and after putting power to it a red power light is all I could get. I tried the reset and still nothing. After watching this video I decided what the heck and went through your procedure. I wasn’t sure how much heat and was easy on it with my heat gun and same problem. I took the board out and tried again with a longer period of heat and that was successful. Thanks a ton for this video!!! I would have likely tossed it. Keep up the great work!!
This was fantastic! This happened to my daughters HU. I did what you suggested and used a heat gun and gave it a shot. Put it all back together and voila! It worked 🎉. Thanks so much for posting this!!
used heat gun on where?? please help. :)
@@sonchan3621 watch around the 4:20 time and you will hear him state that the sister board has a chip (IC500). This is the problematic chip/board area. Heat this area up using a heat gun so that the solder will get shinny and reflow any bad connection. This is what worked for my case.
the processor. Cpu. All this thing ultimately is- is a freaking Microsoft Wibdows head unit. It's just using a mobile version that wouldve been the equivalent of like Wibdows 5 ot 6 mobile version. I would love to know if they sport intel cpus honestly . I want to water cool mine lol jk
I know this is an older video, but I just had a Kenwood DNX892 die on me last Saturday. I couldn't get the heat gun method to work, I think mostly due to my own fear I was going to slag the board since my guns lowest setting is 750 degrees. I did however try putting the sister board in the oven at 350 degrees for 40 minutes as someone else in this thread said they did. It worked! My DNX892 is now working like it's brand new again. Thank you for posting this guide series, and thank you commenters for the discussion that led me to a fix! I new version of this same type unit would have cost me around $1200-1500, so thanks for the savings as well!
DNX572bh here, same condition as in the vid. Followed these steps, heated the board to 250F for about 30 seconds each side, cooled, reinstalled, works perfect. No lie, like magic. I had never "refloated" a board before, but it was easy, start to finish took 30 minutes. Brilliant, thanks for the video, just saved me $500 easy!
How did you heat up the board?
I bought mine in 2015 for twice what u paid lol
This actually works! I just did this to my DNX571HD a few days ago and it’s still working 👍🏼
That’s the radio i have and the issue I’m having. I don’t have anything to heat it with tho
I would like to give you so many thanks. My radio did this exactly. I searched everywhere on what it could be. You my friend are a life saver. I love this radio and it broke my heart when it died. I did the reflow and it’s been working perfectly. Thanks again.
How long did you heat the circuit board for or how hot did you let it get. Thanks, I’m just about to do it with mine
190-220 I used a heat gun and a oven thermometer. Got it to temp and let it cool. Still working great
You are a legend mate, worked for me for dnx5300dab,you saved me a few hundred was literally about to buy a new stereo cheers 👍👍
Thanks for the video, my DNX891HD quit one day driving down the road, just the red light worked, same thing no buttons worked. Took er all apart and heated up worked a treat, working like new! Thanks so much for the explanation
I just had the same problem happen to the same unit you have too. I'm gonna try the reflow right now
Hell Yeah. I bought a DNX 691HD in 2014 and installed it in my 2006 Ford Escape. It worked great for 8 years until yesterday... when it just completely quit. I tried all the fuses then I got out my meter and realized it was getting 12 volts on the red and the yellow wires on the plug (to the black - lead). When I plugged in the wire harness to the head unit the red triangle light on the reset button would come on and the fan would run for maybe 3 minutes but nothing else happened. Black Screen, No buttons worked etc. I thought it was either throw it away or spend money getting it repaired. I watched several of these videos about taking the daughter board off and heating it up with a heat gun. I tried it and it worked. I think the main chip to heat is not the one M.Parsons mentioned but the one in the middle. I used a temp. gun to keep from overheating the board but I got it up over 320° F with a heat gun for a minute or two then flipped it over and same thing. I cooled it off slowly then tested it. The damn thing worked again. I have run the radio and the CD player about 6 or more times over 3 or 4 hours today. It is back to working. I am thrilled! Thanks so much you made my weekend and my week. I spent maybe $700.00 in 2014 to buy it and now a similar head unit is over $1000.00.
This absolutely worked! Thank you for making this video and saving me some money.
You just saved me $1400 ,used a heat gun on the board and it worked ,ty so much great videos
Absolutely worked!!! Thank you so much for making this video!!!!!
MAN YOU ARE AWESOMMMMMMMMMMMMMMMMMME! I finally got around to doing this on a Kenwood DNX 890HD!!!! IT WORKED. I heated up the board for about 1 minute both sides and worked like a charm
I took out the processor daughter board, and reflowed the main processor IC and the suport chips, burst into life (not flames), so far soo good, thanks for the video...👍
So you reflowed everything but the board he's doing in the vid? Sorry if it seems like a dumb question. I'm not familiar with any of this. Just want to fix my kenwood.
Hey thank you for posting this. My DNX571 red triangled out last summer. I used a heat gun on low for about 4 minutes each side and it worked. I’m m so happy. This wasn’t a cheap radio.
Great video !!! I used a hair dryer didn’t get the board hot enough.. so I went back with a heat gun and heated up the board front and back for like 5 minutes. Plugged everything back up! Boom it worked. Got the radio free off my friend and was about to throw it out ! Thanks for the video
I have now a working again kenwood dnx891hd. OMG I couldn't believe this actually worked. I wish I would of made a video beginning till the end.
I want to really Thank you for sharing this with us.
Did the trick for me. Thanks a bunch. It was a Kenwood Excelon DNX692 real expensive unit with nav. Used a heat gun for not even a minute each side. Didn't have a thermometer so I went by feel on medium temp. Going to reinstall it in 2 days. Will report back if it ever goes out again.
Did it work ok when you reinstalled
Thank you and my kenwood dnx4150bt is now working 🙏
What I used was a electronics hot air gun on 350deg for a few minutes by three time and let it cool in between. Pull down your unit and look for the gpu pcb board. It’s the one that holds the cell phone style memory card the
Gpu is close by. “Remove the memory card”!!!! Apply heat gun method and loosely put back together to test it back in your car. Note with removing the memory card you will need to reset up your unit. Back to your bench to reassemble the unit and re-install back into your car, good luck 🙏
Lad you’re awesome. Now I’ll try to reset mine. Great information; Regards
it worked!!!!!!! can't believe it! saved me! thank you!
What did you do exactly?
Absolutely, watch these videos(all 3)...& do exactly as described...I did it and it worked !...thanks for saving me money 💰 🤑 💸
Thank you so much for your help man your thé best
Hey what’s up man so I have a DNX891 HD my friend was going to throw it away and I noticed it is mail as if it was Burned So I was looking at videos in UA-cam and I ran into yours and I tried it and bingo thanks a lot man you’re a bad ass
awsome ! good job thank for your video help a lot. save my money+learn someting.
I’ve just done this. I heated over my toaster (not until golden brown).
It worked. Hopefully will continue to work.
I have a Kenwood ddx9905s used it a couple times, cars a summer car, after winter flickers and has black line down center of screen. Is one with mechanical tilt, so not sure how hard will be to replace.
Thank you brother , you rock . I fixed mine with an old heat gun 🔫 works amazing 🎉
Thanks a lot I tried it an it works
It workt great again!!
Would this happened to apply to single din Heading units as well? I have a
Kenwood excelon KDC-X996
That I purchased years ago but has never seen heavy use I’ve had issues with it since the day I bought it for 400 some dollars Like meeting to have a jumper wire from the frame To an RCA to eliminate horrible feedback That couldn’t be solved after rewiring the harness several times to make sure it was done right as well as the display randomly shutting off but immediately restarting. Being young and dumb when I got it I didn’t take it vantage of customer service nor warranty which it is most definitely out of at this point and now after I spent a bunch of money upgrading my speakers because I missed my old system the display basically never turns on. I’ll be driving regardless if I hit a bump or not it’ll randomly turn on and usually turn off less than a minute later taking the face plate off the red light for the eject button is on so it clearly has power and isn’t losing power it just turns off and it’s not just the display because the sound cuts out along with it unlike when I originally bought it when the display would turn off the music would continue until the display turned back on moments later. I would be eternally grateful and would beyond appreciate Any help fixing this I would even be more than happy to pay someone to fix it Considering to buy a similar head unit with all the same features this one has I would need to sell a kidney to afford it in our current economy. So now I’m forced to use earbuds for music which is not only unsafe but really Fucking sucks since I drive this goddamn truck from coast to coast and everywhere in between 300+ days a year. I just want to hear music through high quality speakers again… Fuck I didn’t even be more than willing to give the friend discount to whoever fixes it if you ever need something delivered that requires Extra care Especially if it’s horse drawn carriages/sleighs, antiques, pianos, or taxidermy. Which are my specialties, PLEASE feel free to reply here and if I don’t answer DM me on my business Instagram @haulinheritage Like I said I would be eternally grateful and would Definitely Owe You one. Thank you.
Would reflowing your chip to any type of radio make the screen turn on? Because I have a DEHp6700MP pioneer and the MOSFET chip looks burnt up could I possibly make it work again if I reflow it because it still turns on but it just keeps popping fuse so I gave it a different ground and it’s turns on but the black light doesn’t
This fixed my Dnx771hd. It turns on now everything works except I don't get any audio out. I get the menu beep noise, but no audio from tuner, disc, usb, Bluetooth, or calls do you know what this could be?
i don't get it. how did you exactly do that? which part of the video exactly?
I have a kenwood 6980 radio has the same problem does not turn on the screen, what you used to turn it on
Hi just wanted to know how often Is this reflow needed because I did it once amd it worked for about a year and it is probably needed again any advise would be greatly appreciated
You know what they say one man’s trash is another man’s treasure amen
Amen
Hi, I have a kenwood DNN991HD, and it’s stuck on the loading screen, I sent to Kenwood and they said that the parts are not available anymore and returned it at my expense shipping and receiving, is there anyway you could take a look at it or tell me what do you think I should do to get it working again please?
Had the same issue with mine. I punched it, and it started working again.😂😂 It shattered the screen and I have no touch screen now, but at least it's working lmfao
kenwood dnx572bh bricked for years, I tried to heat it up b4 but still didn't work. I was about to throw it away but then I tried it again but this time I heated the crap out of it. AND BAM!!! SCREEN ACTUALLY TURNED BACK ON
How do you reset plz! Thank you guys! 👍🏼
Hi, I have a Kenwood DDX5016DAB where the Reset light is flashing and radio does not turn on, Any ideas would be
I have done this a couple of times now but it happens again....although it works perfectly it doesnt last...so am i missing something any help appreciated thanks barry
Hi , any solution for Kenwood loading screen loop ? Does this method work for this problem ?
I got a kenwood dnx521dab, is there a video on that
Okay… how do you do a reflow???
I have no idea what you just did. Because you didn’t actually tell us how to do it
Exactly right
There’s another video on the channel where he shows it. Basically there’s a daughter board plugged into the top. Remove the top cover and dvd drive, then the heat spreader plate, then remove the small board on top taking care to remove all the connectors carefully. There is also a solid black connector on the underside that connects it to the main board.
After you’ve done that, remove the sd card by sliding the metal piece toward the center.
Then on the opposite side of the board(with the big black connector(bbc😏) there is a big black chip😏 labeled Toshiba. Take a heat gun too it on high setting for a couple of minutes. Or just sit the whole board in an oven on 250F for 20 minutes.
well if you listen he did say what to do you reflow the unit it worked for me! wasnt expecting anything but im way happy
so ill be more clear
you have to completely dissasemble the unit remove all circuit boards and coat each one in flux both sides
then you need to heat them i used a oven but a heatgun would maybe be better
make sure do one board at a time and dont heat near plastic parts watch the flux and as soon as it starts to melt take away from heat wait and heat a further two times (the reason is too much heat at once may damage)
let boards cool dont move before cool incase any chips dislodge
this worked well for me my radio is working perfect
THANKS MATE MINE IS WORKING PERFECT NOW!
i just coated all the boards in flux and put them under the grill at 190c one by one i put them under the heat just till the flux melted (less than a minute) then pulled out waited then repeated 3 times for each side to make sure not to melt anything
i got the radio for free after fitting a new one for a customer so wasnt expecting anything ive reflowed stuff before
i put it back toghether thinking it would still not work but its been on my rig for 4 days non stop works perfect
@@hungryhungryhummer not sure if you still active on UA-cam but can I just put the radio in the oven for 20min
Hey Michael. I had a DNX7160 for about 10 years. Last summer it went black while I was driving and never turned on again. Exact same problem. Red light blinks and I can hear parts moving in the deck when I turn ignition on. I tried this trick with a hair dryer but no luck. Any other recommendations?
Heat gun from Harbour Frieght. $12
@@michaelparsons3188 Thanks for your advise Michael. Heat gun didn’t do the trick for me either. Board on my deck looks a little different. I don’t have that big chip. I heated all other chips I saw but no luck.
How long should the reflow be and should I concentrate somewhere specifically? Sorry mine just took a dump. Thanks in advance
Focus in the chip in the other videos I have. There are instructions. I warm up the whole board both sides and than focus on the one chip. Let it cool down for 20 minutes or so before handling the chip after heating it
Michael Parsons .hi give me the address .or the Phons number .thanks
Sir..? Were its tje chip ? Were locate ? How is the chip ? Can help me ? Thanks
I have a 570 with Toshiba chip.. if this process didn't work for me 2x, should I give it a 3rd try on a hotter setting of for longer?
It won't hurt to make it hotter. If its already broken. I was no expert on this repair. I just treated it as an xbox 360 reflow
@@michaelparsons3188 Thanks, I appreciate the reply! I'm taking it back apart for one more attempt because before I had "reflowed" the Toshiba chip, not the microprocessor...
Also I may give this a shot with my 360
i have a dmx7706s and the volume buttons don’t work but when i press on the “menu” button the volume goes down any help?
With the unit that cost close to $1000 you would think that it would last a little longer. I have the same issue, but what my wife told me just prior to it going out is way more important. she told me that she heard a POP sound then there was nothing. I have checked all the fuses on the din unit and also at the fuse box.
good job man u said it was a toshiba chip? Crazy. ppl forget what OS these things use on older units have always been Windows NT variants. Mine even had a license key sticker like they gave out for Windows 7 and earlier
I've got a dmx706s that just completely died last year. No red lights, no power, nothing. I've got it all torn down but havnt found anything that jumps out at me🤔
😲😲😲 I wish I could do this myself!
Hey I tried to update software and firmware on my Kenwood Ddx393 and it didn’t take and the radio is stuck on this mode where the screen starts with a white line that moves across the top as if it is trying to load the new firmware
Sounds like i didn't take the update or it wasn't complete. Make sure thumb stick is formated correctly and reinstall the update
Hey Gee thanks for the video Michael, it's really great you got your expensive Kenwood radios to work but WHAT did you do again? the video says screen repair and I'm waiting to see what to repair ? Please and thanks.... REMAKE!!! :)
Dude literally didn't do anything 👎
I am not a skeptic cause I did it tonight and I got it fixed. Mine is a DNX690HD.
Tried reflow once and it didn’t work. Going to try it again. Kenwood DNX 692.
I have a DNX4150BT that is ... 3 or 4 years old i think.. maybe a tad older. just died one day - no red light, no nothing. completely dead. May try this solution
I replaced my daughterboard on my dnx891hd and now it doesnt have a software keycode. how do i fix that?
Look online. There are ways to bypass codes. Try all 00000
I need a daughterboard. Did the reflow and it didn't work on my DNX691HD. Where did you get your daughterboard? Can't seem to find it anywhere. Thanks.

Where is the video on how you did it?
How can I get ahold of you to repair mine?
Hello I have a dnx571hd, my screen froze as I was driving so I turned it off and now it won’t turn back on. I unplugged the negative side of my battery to see if that would work but the radio still won’t turn on. Can anyone give me some advice ?
I have the same radio.. same thing happened to me and this fixed it !
i need the electrical diagram,,yours can send me...kenwood model Dnx6190hd
Can you post the 2nd video?
Please check my profile. I have 3 videos
@@michaelparsons3188 Thanks bro!
Oh God! I appreciate the information but the preamble is painful as fuck!
I done everything step still getting same result home screen comes on and keep repeating it
Mine died this week after getting my car back from the mechanic for some engine related work. I think it's pure coincidence. The screen flickered a little, the radio would reset by itself, not it's completely dead. Black screen, red reset light, fan on and nothing else. Resetting it does not do anything.
That was my issue also. I picked up 2 decks and sold the one. Both still work. Mine is still going to this day and the one I sold is in a competition spl vehicle with do problems.
@@michaelparsons3188 So all you need to do is heat up the chip set?
Does it still work ?
To this day yes
@@michaelparsons3188 heck ya thats sweet I used your idea and fixed one I have on the shelf a ddx774 or dnx I cant remember exactly 😅 but thank you it was awesome to see it come back to life
Til this day?
Just one question, do you think you can fixe my DDX3....Kenwood? If you do ; send me your address and we’ll deal. Thanks.
What chip you didn't show us anything...
ANYONE WHO HAS QUESTIONS ON WHAT TO HEAT UP, HOW... AND WHERE... CHECK MY OTHER VIDEOS FOR THE BREAKDOWN OF WHAT AND HOW TO DO IT.
I srill have a halo edition xbox360 with red ring of death... As well as this dnx570hd.
So basically put a heat gun to the chip get it hot and put it back in ok I'll try that
fix did not work for me (heat gun at 250F for 90 seconds, then 450F for 60 seconds; both sides 1x; side with that IC500 chip 2x).
for anyone with confidence in the fix, my DNX691HD is for sale @ $100 (plus shipping). Just let me know.
Everyone swears by Kenwood but mine has been nothing but the biggest piece of shit.
Dnx892
He said a whole lot of nothing -.-
