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.
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 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.
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.
Well, yes and no... There are obviously DVI/ HDMI adapters on the market which simply are consuming more current than others. If you have such a" high consumer" that is bad...
The "adapter" doesn't consume any power at all... they are (by spec) just straight-through cables no more active than a DVI-DVI cable... the actual device (DVI or HDMI) may consume within a permitted limit of steady-state current, which is different when the device is off (or not plugged in) or on. The hot-plug requirement means the fuse must survive brief inrush current (be slo-blow). The FTDX10 design obviously didn't take this into account.
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.
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.
Hi The 5V is put to pin 14 of the dvi socket after the dvi/hdmi chip , so the chip can be bad, it is that this one is lucky the fuse did its job, i have 5v on pin 14 but no output on the dvi socket, Dave
@@davidbrowne1588 Hi, no I haven't done anything as I have to send my radio 1 thousand klms for repair. I will just live with it as it's too risky to post in the mail. I thought using the correct DVI cable would eliminate this problem, not so.
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.
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.
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
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.
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
Hallo Ralf, schau mal welche Firmware auf dem Gerät ist. Sollte es die erste sein (1.0), kann das der Grund sein. In diesem Fall Total Reset und dann die neue Firmware drauf. zu 25% aller Fälle ist es damit erledigt...
@@TRXLab Hallo Peter, vielen Dank für deine Antwort. Firmware ist die neueste verfügbare. Ich werde das Gerät demnächst mal an anderer Stelle testen mit anderem Netzteil und anderer Umgebung. Das Problem tritt auch am Dummy auf, unabhängig von Mikrofon oder Sendeleistung. Vielleicht sind es ja tatsächlich äußerliche Einflüsse?🙈 Ansonsten muss ich mir eine sinnvolle "Verwertung" einfallen lassen. 😉 Schönen Sonntag und Vy 73, Ralf
wenn die neuste Firmware drauf ist, sonst keine äußeren Einflüsse zu finden sind, wird es eng. Es gibt dann im Prinzip nur noch 2 Fehlerquellen. 1. Ref Ozil. 250 MHZ an TP1097 Main Board. Da reichen schon mehr als 30 Hz Toleranz, um das auf SSB zu hören. Je größer das Delta, desto schlechter SSB. 2. Da es keine SSB Komponenten im analogen Teil des Gerätes gibt, wäre das dann ein Fehler des SDR FPGA. Das wiederum glaube ich nicht an erster Stelle, da ja alle anderen Modulationsarten funktionieren....
@@TRXLab danke für die Hinweise lieber Peter. Der 250er ref. Oszi scheint leider nicht das Problem zu sein. Die SSB Modulation klingt eher wie "FM'ing". Ruheströme der Endstufen oder einer der (Vortreiber/Treiber) bzw Endstufentransistoren könnte ich mir vorstellen. Leider will sich niemand der Sache annehmen. Ich habe auch keine Hinweise von den Hinterbliebenen erhalten wo dass Gerät erworben wurde. Im Endeffekt wird es wohl leider ein teurer Türstopper. 😔 Wünsche dir einen schönen Sonntag und freue mich auf baldige neue Videos von dir. 73, Ralf DO7RU
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
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?
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
DVI-D to HDMI adapters don't have any electronics in them and don't draw any power - the two standards are signal compatible. It just requires an adapter to route the wires between the connectors.
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.
@@TRXLab I am sorry! It was sarcasm. I have seen such damage before, including a burnt out chips. People are forced to use crappy DVI-HDMI adapters; DVI does not allow re-connection without turning off the transceiver and monitor. This causes damage. All this could have been avoided if HDMI had been used instead of DVI.
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
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.
@@mikesradiorepair to me it looked like two soldering irons. just went back and your correct. it was such an quick off i just saw the meter probes looked away and it was off. I sit corrected. 🙂
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?
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.
HDMI also provides voltage. If Yaesu implemented dvi badly then they could do bad hdmi implementation, too.
