Re: Tip of power plug stuck in socket
Heat up a needle then poke into the plastic, when it cools you should be able to pull it back out with the plastic attached. May take a couple of attempts to succeed, but quite a few people have reported success using this method (thankfully I haven¡¯t needed to as many years ago I went to a permanent connection with a powerpole instead). ? ?

Subject: [ft817] Tip of power plug stuck in socket? I recently purchased a used 817 and I just discovered that the yellow plastic tip from a power plug is stuck down at the bottom of the power socket on the radio.? Any suggestions for how to remove that from the socket?
Worst case, is that power socket available so I can replace it?? Got a DigiKey part number??
Thanks!

Re: FT-817 almost powers up
If the finals are shorted, will the 817 not power up?

Re: FT-817 almost powers up
Today's Update
- I found there is no connection in the power jack? from the outside barrel side (negative) to the trace that runs to the common mode choke (negative side). I've soldered a wire to the jack pad so I can power the rig up on external power.? With that in place...
- When I plug in external power, as before the rig coms up with all segments and icons black, and if I shine a flash light on the LCD I can see it's trying to display the charge status (CHG TIME RMN and a count down timer.
- If I press the PWR-ON,? it tries to boot and shuts off. Removing the power plug and re-inserting takes me back to bullet 1.
If I run on just battery, it tries to boot, and shuts off. Both internal fuses are intact, and I see good battery/line voltage to the display board, and +5v on the display board regulator and the reset chip next to it. Seems like something is dragging it down before it fully boots up.? I am assuming the CPU is good because it can display the charge time. Bill

Re: Help please ... FT817ND not getting power from rear connector, ok on battery
This was exactly the trace I repaired this Tuesday... Looks like I am in a good company

Re: Help please ... FT817ND not getting power from rear connector, ok on battery
I had a strange occurrence with mine. There is a chip cap right near the connector on the pc board that blew up. It took out the trace from the connector. The chip cap was only rated at 16 volts, on the 13.8 volt line.
This doesn't look like enough leeway in voltage to me.
I repaired the pc board trace and put in a chip cap rated at 25 volts.

The DC connector is a definite weak point. There is a very thin PCB track which can fracture. Also, frequently taking the plug out and back in again can loosen the solder joints from the socket to the PCB. I had this problem a while ago. Unless you are REALLY skilled with the iron (which I¡¯m not!!) it¡¯s a job for the professionals. Then when it¡¯s been repaired, fit the rig with the type specific Power Poles. That way, you can disconnect the PPs as often as you like, as the PP connector stays permanently attached. Yaesu UK did mine for a very reasonable price. 73 Ivor G4RJA On 2 Sep 2022, at 08:10, Bryan Nehl <k0emt@...> wrote:

Re: FT-817 almost powers up
Hi
It has been a while since i read about this sort of fault but i do remember someone saying that there is a common mode filter in the power rail at some point and that with a reverse polarity feed and a chassis ground that the negative rail can be taken out. A quick way to check is DC ohms check from the negative lead to the radio chassis.
A long shot but hope it helps

Re: FT-817 almost powers up
Hello,
just my experience from this week.
After a repair and a mod (SEL encoder, and Sotabeam filter) everything was working fine. A few days later I tried to power up the radio and I wasn't working?anymore - no sign of life.? I don't have any internal battery installed so I could check only with external power supply.
I was a little bit puzzled at the problem, because?the main bus voltage was not consistent between measurements.
At the end I was able to track the issue down to a broken trace (the one near the power plug?which?connects the negative of the power plug to the choke filter. So based on where I put the negative lead of my multimeter I could see or not see a voltage. After repairing this track everything went fine and current consumption?is normal.
I still don't know the reason for the broken trace. I could see corrosion due to a precedent repair in the area (probably?power connector replacement and corrosive flux left in the pcb), which was noticeable even on a picture?I took at the radio just before?repair and mod, exactly on the broken trace.
Hope that helps,

Re: FT-817 almost powers up
b,
Is the VOM reading with the power connector plugged into the FT817.
If you do then I would think the connector has lost it's connection to the FT817 ground/neg supply connection.? If not in the FT817 then I would be concerned if the cable connections are reversed and the fT817 has another path to ground.

Hello Bill
I do not have a circuit (schematic) for the 817 here but I do know that the much earlier FT290 and FT690 had a reverse polarity diode in the negative pole of the DC power connector.
If the FT817 is similar, I would investigate the health of that, or any other, reverse polarity protection circuit / device.
Hope this helps
