939 Help! Hakko's Lockout Instructions don't work

[ComputerGeek]

Hey guys I want to know your opinion did I get these for a good price?

http://www.ebay.com/itm/270924979268 $35.00

and

http://www.ebay.com/itm/270921072369 $9.50

Total without shipping 44.50. Was that a good deal?

Of course its in order to be popped open and have the cord replaced, and the lockout card bypassed. I never did know why they put the lockout card's in the only thing I could think of was for some Chinese worker that you didn't want to change the settings.

I think you did fine, provided it all works. Get some various tips and a spare heating element, if they are still available. These were discontinued 8 years ago.

Do you think it was a deal or just average, providing it all works great?

Re: Hakko Soldering Iron Ebay Find!

You got an industrial grade, temperature controlled, and solid brand soldering station for <$60. You're just going to have to chase the parts for it a bit. You should be able to come up with enough of them to keep it going a long time.

if you think that it works great and you are also not short of money they you should go for it

Hey Guys, I got it in today, I Removed L6 from the sensor board as per the lockout bypass but I still am not able to adjust Temperature settings. Any Ideas?

Post picture of board,top and bottom.

Re: Hakko Soldering Iron Ebay Find!

Which one just the Sensor board?

[cmj21973]

Re: Hakko Soldering Iron Ebay Find!

All boards just to be safe.

Re: Hakko Soldering Iron Ebay Find!

Here they are. I'd rather not take the board near the transformer off as I always wreck those plastic clips but if you absolutely need it, I'll get the back for you.

Re: Hakko Soldering Iron Ebay Find!

I understand completely.
I hate those things. I normal replace them with nylon bolts, spacers, and nuts from hardware store.

Can you take an over all picture so I see how the wire cables connect the boards together.

Besides removing L6, did you do any touch up (reflowing) soldering on that board?

Does the iron get hot?

No I have not not touched up any of the boards. Picture is attached for the connections.

Also, just to make sure I am doing this right all I have to do after the lockout is disabled, is press the "R" button and then enter the number and press "S", right?

Does the iron get hot?

Yes the Preset temp is currently set to 650F and it heats up to that temp very quickly and seems to stay there.

Thanks guys hope this is a simple fix.

Re: Hakko Soldering Iron Ebay Find!

I'd make my own keycard and put that L6 back in. Does it even look like it's setting when you press R ?

[cmj21973]

Re: Hakko Soldering Iron Ebay Find!

Yes, right steps.

1) Does the heating element and the digital display immediately turn off after press "R"?

[ComputerGeek]

Re: Hakko Soldering Iron Ebay Find!

No they don't even respond, the switch for "R" is working.

Re: Hakko Soldering Iron Ebay Find!

If there isn't any solder bridges on the sensor board, then the problem is on the main board.

[ComputerGeek]

Re: Hakko Soldering Iron Ebay Find!

Yeah, that what I was thinking. I don't see any solder bridges where do I start on the mainboard?

Re: Hakko Soldering Iron Ebay Find!

I've looked and can't find a schematic, so we (BADCAPS Forum) need good focused pics of the boards tops and bottoms.

We need this to be able to trace the circuity.

If at all possible use sunlight to illuminate boards or indoor lights, no flash.

If the plastic standoffs get broke, we'll replace them with better ones.
