Bricked Kenwood DNX. Cheap fix.

[@jesseowens4652]

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.

[@mperdue12]

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.

[@benyancer154]

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

[@RSayGV]

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.

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.

[@MrFreevo]

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??

[@Connors_Ultimate_Motorsports]

@@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.

En verdad funciona , mi radio tenía ese problema , muchas gracias , me salvé de comprar otro !!! 🙌

[@68pishta68]

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.

[@68pishta68]

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!

How long do you have to reflow?

[@dixy2k]

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]

@@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.
