Yaesu really dropped the ball here. Customers would be MUCH happier with the HDMI jack and none of this drama. It is was a mistake for them. Great video. Thank you.

In my younger days as an ET, I was checking a tiny resistor like that and when I checked it with a meter, it read OK. Chased my tail for a while, everything pointed to that resistor being open, yet it read OK. Then, I connected my meter leads to adjacent components connected to that resistor (11:45) and it read open! The pushing together of the meter leads on the resistor was enough to push the cracked resistor together and allowed it to read OK. I learned a valuable lesson that day.

God’s Blessings on that fix! That’s going to make a lot of FT-10DX users happy ❤

Nice work, Peter. I guess, Yaesu´s choice for DVI was the licence fee for HDMI. There is no other good reason in my opinion. Saving 1.5 USD each TRX is more important than satisfied customers...the bean counters took over ;-) Thank you for a nice vid - again. Genieß den Herbst, ideal für viele schöne Videos, Peter. Bleib gesund und 73 de Olaf.

I did not know that an adapter could do that. I did not know there was a 5 volt line going through the DVI ether. Good to know. Thank you for the peek inside as well.

Thank you very much Peter, I will definitely buy a DVI monitor for my brand new FTDX-10 radio !!!

Thank you for sharing your technical experience with the Yaesu FTDX-10 external video display issues. I was going to purchase this model until I heard about the external video issues. Now I feel more confident about ordering one. I really need to learn how to solder SMT components. I have a SMT repair station.

Thank you for a superb video production Peter

Thanks for confirming what many of us thought. My only quibble is, it isn't a bad DVI-HDMI "adapter" problem (it's not an adapter, it's a pin mapping documented in the HDMI spec), it's Yaesu's design, specifically that fuse value. Since the spec calls for both hot-pluggability and for the source (the FTDX10) to actually power some monitor circuitry when the monitor isn't on, that fuse needs to take that into consideration.

I really wish that Yaesu would "JUST" sell an 'Approved' DVI-to-HDMI adapter. Or at least "JUST" publish a white paper on exactly what to do, perhaps making sure that the adapter has such-and-such characteristics. It's all madness. Edited to add "JUST" in 2 places. Somehow the word "JUST" makes it all okay.

Another nice repair video excellent soldering skills especially dealing with surface mount components.

Thanks for this mate. My weekend TRX lab fix!

Very nice job! Well done and well documented, many thanks

Thank you Peter. I have not seen this radio yet.

Peter, thanks for your reply. Because pin 14 had 5v I assumed the chip would not be faulty and that's why I asked for your advice. Thanks again for your time.

The +5 volt on pin-14 is there to keep the monitor awake. If it disappears, any display thinks the DVI source is turned off which puts the display into sleep mode.

Thanks Peter. Great job. 73s

Hi peter thanks once again for another video the owner was lucky it was only that tiny fuse and not the chip electronic have got smaller in size must be hard for you to see such tiny things hard for the eye to see them.

OMG so cool. Thank you

Great video, thanks.

Hi Peter, I had heard that there are only a few HDMI - DVI adapters that will work with the FTdx10. Glad I still have a DVI monitor available. Stay safe. 73 WJ3U

Thanks for this valuable information. 73s 😊

Popular radio. I own Yaesu FTDX10. I've read about problems with external display connection. Seems this may be common problem and solution. Thank You.

I know it's Saturday when Peter posts a video; thanks.

tnx vy 73 👍

Wie immer ein top Video, Peter. 👍Schön dass du dich an den FTDX10 ran traust, den Fehler und die Lösung präsentierst. Habe selber einen FTDX10 der eine Reparatur benötigt. Das Gerät hat eine miserabele SSB Modulation. Leider ist die Garantie bereits erloschen, da es ein Erbstück ist. Leider scheint sich keiner an das Gerät ran zu trauen. Alle meine Anfragen blieben unbeantwortet. Vy 73 Ralf

Instead of replacing the fuse with another fuse, could it be replaced with a resettable “fuse” or circuit breaker?

Great video Peter!! Hey, could you tell us what that tool was that you actually pulled the fuse with and also what flux you used please?? Thanks.

D1800 Ifsm for RB521SM-30 is only 1A. My understanding is Yaesu on the FT-710 has upped the Fuse to 1A for that port. I suspect they must have upped the rating for the diode too.

Awesome video. You mentioned people could end up using the wrong DVI to HDMI adapter and to be careful. Can you post or point us in the right direction to the known good converter so we do not make that mistake? Thanks

Great video as always! What brand/type flux do you use?

You can get DVI to VGA adaptors, might e worth picking up a couple

What is the part number for this fuse?

Thanksfor that, i tryed open myft 710, but i guess this fuse is on the otherside......any advice? What do u think if a give 5volts on pin14 on the cable from an external source???the monitor should work, shoundn't it?

What would you charge for a repair like this Peter *?* *Cheers* *73*

Hi Peter. Wonderful Video. What DVI-D to HDMI adapter, exactly, would be safe to use, are there any? I was informed by a very helpful Yaesu Support Technician that the CABLEDECONN Multi-Port HDMI To HDMI/DVI/VGA Adaptor was the best one to use (I was sent an Amazon link). I tried using that adapter with the Yaesu recommended DVI-D to DVI -D cable connected between the FTdx10 and the adapter and a good quality HDMI cable running from the adapter to a Dell U2415 HDMI monitor without any success, no signal apparently available at the monitor. Either the FTdx10 DVI-D Port, or the CableDeConn adapter itself appear to be nonfunctional, or - even worse - the trial of the adapter itself resulted with the FTdx10 dreaded blown fuse scenario, and I am not sure how to test out the port other than by connecting a DVI-D monitor. Any ideas for the best next step? I have notified the tech at Yaesu, but so far it is too soon for a reply. Thank you all. W6EO

Can't we just feed +5v to pin 14 of the DVI port and cut the trace to the fuse if it's not already blown? Isn't that the same effect? Isolating the chip from being damaged while supplying +5v to the display and keep it awake. That seems to me is a rather simple soldering job if you have a steady hand and a magnifying glass. Or replacing the fuse with a, say 20 or 50 ohm, resister?

Have you noticed you made a nasty solder flake with your probe on the diode pin (last test presented). I hope it will not fall off. Or short to the groundplane. Yaesu learned and FT-710 has a better solution - resettable polymer fuse.

I love these videos of Peter and Olaf ... 73s de DL6RDE / AA1KD, Charlie

It was very wise decision to use DVI instead HDMI

Hi Peter, I have just got myself a FTDX-10 and yes when i tested it there was no video from the DVI-D Port so i hopped it would be the same as this one, but no, the 5v on pin 14 is good, i all so tested all of the resisters around the dvi chip and all ok, also there is 3.3v to the chip, so it looks like it is the chip, when i was testing with a scope at the dvi port i did see some signals , they did not look clean then i looked at the frequency and yes it was only the 50hz mains interference, have you found meany of these radios with a blown dvi chip, Thanks Dave 2E0DMB

Thanks for sharing this interesting video Peter, as usually nice job. 73s de IW0HEX Pasquale.

you must run a dvi-d monitor with that radio or you will have that problum

Hi Peter, I have the same issue but I have 5v on pin 14. I have continuity tested the DVI-D cable and only have continuity on pins 1-2,7-10,14-18,22-23. I don't want to send my radio 1 thousand kilometers to be looked at if its not a blown fuse. Any advice would be appreciated. Love all your videos. Thanks for all your advice.

What is the rating and spec of the fuse Pete ? thanks

Have you thought of getting a pair of de-soldering tweezers they make the problem of removing SMD R's, C's etc real easy and without the mess of flux.

If you are that good at replacing a tiny fuse like that then you could fix my original Yaesu FT-817. It has a problem that even Yaesu could not fix. In fact they did not even know if it was a problem as they checked their report logs and did not find anything resembling it. Another ham said it could be a few SMD resistors that have given out as the main screen characters fade even though the back light is on. They sent it back unfixed even though everything works except the display fades leaving a blue screen that it was already set to. Fancy a poke about to see if it can be fixed?

Is there an adapter sold on Amazon that you can recommend that will be 100% safe to use?

Hi David, I am in Australia. What are you doing to fix the display fault. I would like to fix it myself if possible. Thanks for your info.

This fuse is SMD (size 0402?) and has a value of 0.63A, can you tell where this component is purchased? Thank you

yaesu said it be about £300 to repair my ftdx10

i got a blury green screen on my external monitor even yaesu dont know what it is can anybody advise me please

Immer diese Sicherungen!

if they had the hdmi chip in the radio why the heck didn't they give us. an hdmi connector. so much easier

This is why I don't buy Yaesu crap anymore. Everything on my FT-897d went bad soon after I bought it years ago.
