'[PIC] Can Picstart Plus be Repaired?'

Hi:

My Picstart Plus fell on the floor and now when I try to use it MPLAB
says there's a serial com failure.

Is there someone that repairs these?

Thanks,

Brooke Clarke

Brooke, can't imagine a PS+ would sustain a huge amount of
damage, like a cracked PCB, from that. Have you checked
inside to see if any components (eg C44 or PUM) are loose ?

Microchip may offer an exchange program. But I'd pop the cover and look
for a lifted pad on one of the connectors. That's about the only way
that physical force can be transferred to the board-- probably the DE9,
assuming the power LED is coming on.

Microchip is pretty good about exchanging broken dev tools (usually
with refurbished units) - often at no cost to you.

I'd give them a call.

Have you tried the obvious?

Shake it and listen to see if any crytal(s) are broken?
Looked for broken traces at the connector pins?
A few quick hits with a hot iron and solder usually takes care
this sort of 'damage'.

And a chip may have popped out of it's socket.

'Solid state' stuff is pretty hard to break with simple drop.
At likely have a few cracked traces, which should be easy to spot.

Hi:

I called microchip this morning and they do have a replacement program
and will be sending a replacement.

The power LED is coming on.  A scope at Y1 shows 25 MHz (I thought a
crystal was the most fragile thing here), so the xtal seems OK.
A look at all the parts under a microscope shows nothing abnormal.  The
traces for the DB-9 connector are hidden between the PCB and connector.  
The PUM was not fully seated, but removing and reinstalling it did not
change anything.  So it will be going back to Microchip once the
replacement arrives.

I was experiencing problems bringing up the ICD2 and as part of that
troubleshooting process came across DS51417B "Uninstalling Incorrect USB
Drivers" and after snooping around using the Registry search discovered
that there were a bunch of Microchip items registered in the directory
for my ATI video interface.  On the phone this morning I learned that
these can be removed by cleaning the registry using the tool:
program files\Microchip\MPLAB IDE\Utilities\MpUsbClean\MpUsbClean.exe    
Now the ICD2 will program my parts.  Still learning how to use it for
debugging, which will come in handy.

Have Fun,

Brooke Clarke
