All,

I replaced the lamp hoping this would solve our failure to ignite 
problem.  Unfortunately, it did not.  I have sent a help request to 
Woollam and I am waiting their response.

Regards,
Ed

All,

I have heard back from Woollam and it's not a quick fix.  I seems we 
have a failure in our igniter circuit which requires some component 
replacement.  I working on the logistics whether we can make the 
repair of the unit with supplied parts or if the unit needs to be 
sent to Woollam.

Message-ID: <6.2.5.6.2.20100916084403.05318178@stanford.edu>

All,

I replaced the ignitor board, but it did not solve our problem.  The 
next step will be replacing the power supply.  Woollam shipped to us 
the power supply with the ignitor board, but they were expecting the 
board to be the problem.

Ed

Subject: Woollam is UP

All,

Sorry to disappoint those lab members who have decided to head to 
Mexico instead of making Woollam measurements, but the system is now 
up and available.

The ignitor board (not the problem) and new power supply was replaced 
(which was the problem).  I also replaced the lamp, aligned the beam 
and calibrated the system.

I need to thank Woollam for sending the part for trouble shooting and 
even more importantly the step by step directions so that even I 
could make the repairs.

Regards,
Ed
