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!!

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!

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!

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 actually works! I just did this to my DNX571HD a few days ago and it’s still working 👍🏼

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 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.

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.

You just saved me $1400 ,used a heat gun on the board and it worked ,ty so much great videos

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.

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...👍

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 🙏

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.

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 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.

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 👍👍

i don't get it. how did you exactly do that? which part of the video exactly?

Absolutely worked!!! Thank you so much for making this video!!!!!

I’ve just done this. I heated over my toaster (not until golden brown). It worked. Hopefully will continue to work.

I have no idea what you just did. Because you didn’t actually tell us how to do it

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

This absolutely worked! Thank you for making this video and saving me some money.

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

Absolutely, watch these videos(all 3)...& do exactly as described...I did it and it worked !...thanks for saving me money 💰 🤑 💸

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.

You know what they say one man’s trash is another man’s treasure amen

it worked!!!!!!! can't believe it! saved me! thank you!

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?

Thank you brother , you rock . I fixed mine with an old heat gun 🔫 works amazing 🎉

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, I have a Kenwood DDX5016DAB where the Reset light is flashing and radio does not turn on, Any ideas would be

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🤔

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

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?

😲😲😲 I wish I could do this myself!

I am not a skeptic cause I did it tonight and I got it fixed. Mine is a DNX690HD.

Okay… how do you do a reflow???

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

Lad you’re awesome. Now I’ll try to reset mine. Great information; Regards

Hi , any solution for Kenwood loading screen loop ? Does this method work for this problem ?

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

Oh God! I appreciate the information but the preamble is painful as fuck!

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 KZfaq and I ran into yours and I tried it and bingo thanks a lot man you’re a bad ass

Thank you so much for your help man your thé best

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

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?

I got a kenwood dnx521dab, is there a video on that

Where is the video on how you did it?

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

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?

Everyone swears by Kenwood but mine has been nothing but the biggest piece of shit.

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!!! :)

awsome ! good job thank for your video help a lot. save my money+learn someting.

How can I get ahold of you to repair mine?

I have a kenwood 6980 radio has the same problem does not turn on the screen, what you used to turn it on

Tried reflow once and it didn’t work. Going to try it again. Kenwood DNX 692.

I done everything step still getting same result home screen comes on and keep repeating it

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.

How do you reset plz! Thank you guys! 👍🏼

Sir..? Were its tje chip ? Were locate ? How is the chip ? Can help me ? Thanks

Thanks a lot I tried it an it works

It workt great again!!

What chip you didn't show us anything...

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

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?

How long should the reflow be and should I concentrate somewhere specifically? Sorry mine just took a dump. Thanks in advance

So basically put a heat gun to the chip get it hot and put it back in ok I'll try that

i need the electrical diagram,,yours can send me...kenwood model Dnx6190hd

Does it still work ?

I replaced my daughterboard on my dnx891hd and now it doesnt have a software keycode. how do i fix that?

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 ?

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.

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.

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.

Can you post the 2nd video?

I srill have a halo edition xbox360 with red ring of death... As well as this dnx570hd.

Just one question, do you think you can fixe my DDX3....Kenwood? If you do ; send me your address and we’ll deal. Thanks.

Dnx892

He said a whole lot of nothing -.-
