hi,

solder a 1k Ohm resistor
between trigger / middle
contact and flash mainboard
connector.

in the picture:
Resistor Color Code:
brown black black brown
with 1% tolerance (brown)

please send fail or succeed
stories.

thanks,
tx0h

Why should Pentax fix a problem from a different company?

WOW!

thats so cool! a success story!!

thanks for let us know, this may encourage
people to take the solder iron in the hand
and put this dumb 1kOhm resistor in place.

greetings,

tx0h

This is also a problem with my ricoh grd iv, but I can't bother fixing it, since I use the flash from wireless triggers and they fire just fine.

Hi Filip,

OK, thats another flash type.
Which method did you try?
The capacitor (#7) or the
resistor (#15) method?

Dear Sir!
Thank you for your quick reply,

Im pretty much poor in any hardware modifications, so I asked my friend to help me out, he tried with most of the cables I guess[resistor not capacitor],
What we achieved is ''sound'' button makes sound now when you press it [didn't before], flash goes back to normal after removing it from the hot shoe, before I had to take all batteries out to restart.

Please help me! I am so frustrated !

Thank you !

Sir ! Just wondering now if they sold me correct resistor! :/
Mine is different than yours, brown/silver/black/black/brown.
Will this make anything if the number is higher ?

sure this makes a difference. you soldered a 1Ohm resistor and not a 1000Ohm resitor.
the reading is brown black black silver, btw. should be brown black black brown.

a 1Ohm resitor may not make such a big difference, but 1k Ohm is a 1000 times
stronger resistance and i would give it another try. such a resitor is very cheap.




greetings & report back,

tx0h

I'm so excited. Thanks to the suggestions on this thread, 45c for the resistor and my Dad's soldering skills I now have a YN-560 II that works on my K5. We attached the resistor to the yellow wire. So excited! Thanks again helpful people.

update

I just ordered this flash, YN560II, and I was prepared to do this when it arrived. Well I didn't do this yet,andI have been using this with my pentax k5, and so far I have no issues. I took the bottom apart and mine looks different from the other pictures above, so maybe yongnuo updated their flash to fix issues like this?

i'm sure there is such a resistor in the heat shrink tube. so yours is fine :-)

Hey, this sure is an interesting thread, and thanks all who have contributed fixes. I have the original 560, same as the one in the original fix. I tried both a .1uF and a .01uF capacitor and neither worked. I know the flash is fine as it fires reliably when connected to my triggers. However, my transmitter has a similar issue as well. It works about 5% of the time when attached to my K5 IIs hotshoe, but 99% of the time when unattached.. Considering that my transmitter is also having issues, though, I can't help but wonder if there is something wrong with my hotshoe, and not the triggers/flash. I have not tried a resistor instead of capacitor, will see how that goes. Anyone else think this could actually be a QC issue with K5 hotshoes?
