APC40 Owners - Anyone feeling adventurous? PCB help needed.

[danielbriggs]

It seems the APC40 isn't quite road hardy, despite being kept in a padded flight case designed especially for it.
A recent knock while on it's travels has forced the USB connector to retreat back into the housing, and has sheared off 3 SMD resistors in the process.

Would anyone be willing to take the back cover off their APC40 and measure the resistance values of the three mystery components directly behind the USB jack on the main input board? (Or infact confirm they are resistors / caps etc.)
I would be massively grateful (+it would be worth a beer / JD on on me at the next UKLEM)

If not, a replacement main PCB is ~£95 from the US, and failing that, a new APC40 is the best part of £300.
Not the end of the world, but if I could fix it for 'aaaaaaalf a paaand, then I'd be happy.

I'm fine with repairing the board; if only I knew what to slap in.

Cheers!

How did this happen? The USB socket is flush. Did the foam compress and push it in? Sounds like you need to mod the foam, a little cutout to reduce the pressure point.

I found a photo of the board, 3 x resistors in line behind the USB socket. Trace the resistor pads, If 2 of them go to the USB socket, pins 2 & 3 then these will be something low like 22R to 82R (not really that critical the value) and the 3rd may well be the usual 1k5 pull up between VCC (3v3 or 5v0) and pin 2 (D-). Here is a typical USB interface.

You slapper you.

Wayne,
You're a gentleman and a scholar. Thanks!

The three components have gone to the same void in space-time as things that fall off a desk and the floor eats.

I'll pull it to bits again when back at base and further inspect. I just tore it down on a gig as had a spare hour.
The USB-B end of the cable was left plugged in; that must have hit the back of the case and pushed it through.

Note to self: don't leave pluging-in-type-things-plugged-in.

Yup. There's your problem right their... Chop.

We really need a like button.

Let me know if you don't get any luck. I have one open on the bench with exactly the same problem! I can look when I'm back from this gig tomorrow.

Lawrence,
That would be superb of you, should you have time.
Thanks in advance!

That is what you get when using toys

And the ability to tag/notify people in posts / threads.

Lawrence,
Did you manage to take a sneak peak at those IC values? If not, I'll just take a punt and go with Wayne's idea.

Cheers,
Dan
