Another great vid. One of the things I like about your repairs is how you also deal with potential problems as well as the actual problem. Touching up all the solder joints on that board is something only very few engineers would do. In fact, the majority would have only disassembled to the point where they could see that board, seen those broken joints on the jack, re-applied solder to them and then put it back together.

Great video. I was looking at this to help me understand why I was just getting static with no signals heard and no transmit. I read the manual (duh....) and still couldn't figure out what was happening so I searched and found this video. I was encouraged by his clear and logical troubleshooting sequence and emboldened enough to open up the the top case and peak in. His recommendation to change the memory cell was helpful and I changed it. My guess is the previous owner never changed it as it looked a bit tarnished and slightly corroded. There was nothing obviously burned, exploded, smelly, etc., so, I reassembled and powered it up again and, Viola! It's working! I'm not sure changing the lithium cell did much and the manual didn't say anything about it other than it was the memory keep-alive but maybe it has undocumented/hidden function. Again, great, clear, and helpful video.

Something so simple causing such a big problem ... I would not have thought about the head phone jack being the problem unless the owner said they use the headphones a lot of the time. A real strip down needed for this repair, good thinking that the closed contact allows the speaker to operate ... I bet the repair shop did not want to do the hard work of the strip down ... good idea to insert the jack and move it around just to listen for life and your detective work paid off really well done on solving the fault.

I have an FT 900 that I was using for Air Force MARS in the mid 1990's. One September night after shutting down my station at the conclusion of the MARS net, I neglected to disconnect the antenna. That night we had a severe thunderstorm and a nearby lightening strike took out the radio. It was completely dead and wouldn't even power up. I contacted Yeasu to see about a repair and they refused to repair it saying that the radio was obsolete. I boxed the radio up and put it away. A few months ago I contacted a repair shop to see if they could repair the radio and they agreed to look at it and give me an estimate. I was boxing the radio up to send to the repair shop and decided to include a copy of the service manual with the radio for the convenience of the repair shop I was thumbing through the manual and noticed a reference to what the manual called a "Hard Reset" using a tiny little switch on the bottom of the radio. This was accomplished by flipping the switch, powering on the radio and then flipping the switch back to the original position again. I had already tried the "Soft Reset" but, since the radio would not power on, it was not possible to accomplish a "Soft Reset". Well, the "Hard Reset" did work. I could find no reference in the Operating Manual for a "Hard Reset", only for the "Soft Reset". Only the Service Manual had instructions for a "Hard Reset". I saved a lot of money because the radio was not really broken, but I lost the use of the radio for about 20 years. I learned a couple of lessons the hard way. Always disconnect the antenna when you are not using the radio and when all else fails read the manual. Of course the Service Manual did not come with the radio, but now you can find almost any manual on the internet. A word to the wise, download a service manual for every radio you own and read it. The Service Manual contains valuable information not included in the radio Operation Manual. Paul, I always enjoy your videos. I envy your skill and intelligence. I salute you sir. John K4AGO

If you could find no trace of the repair shop having been in there, I'd question whether they actually even opened it up. Years ago we had a TV set going bad with an intermittent (and eventually solid) green screen. Took it to a local repair shop, they came back and said it would need a new picture tube, $300 or more. We said no and brought the thing home. With nothing to lose I took it apart outdoors and found the inside was absolutely filthy with dust, and no marks whatsoever that they'd even touched it. I blew all the dust out and gave it a good cleaning, and the thing worked perfectly for another 2 years before it finally went belly up.

I think I would have replaced the jack anyways after all the work you did with disassembly. Every time you insert a jack it scrapes off a microscopic amount of metal and they just get worn out....plus the spring tension weakens as well. I would assume the jack is fairly inexpensive so with all this labor time it deserves a replacement. Since you are in favor of leaving things "better than factory" our shop used to have an electrolysis gold plating kit (pace?) so you could gold plate connectors, edge connectors etc to give them really low resistance! Pricy but worth it for expensive mission critical industrial applications since I see you repair cnc gear that costs the customers a lot when it goes down...

Hello Mr Carlson, I have an FT-890 which is now doing the same thing my old FT-900 did, blinks out from 14.5MHz down through the 160 band, then comes back in for the Standard Broadcast band. I presume VCO caps? Have you a ballpark guess, ballpark cost for average repair of that type? I love the little guy, but is currently only working fine from 17m & up. I'd love to have it back for my 2 favorite bands, 40m & 80m. (wimpyradios - gmail)
