RE: [APML] Re: ST4 malfunction

["Lane, Jason R" <jason.lane@navy.mil>]

Double check at your CCD chip to make sure that none of the wires are touching.  You may have accidentally jogged one while replacing the dessicant ring.  Other than that, I second Chuck's advice that it's difficult to trouble shoot something like this over email list, and so probably your best bet is to send it in for servicing.

Cheers,
Jason

"Unfortunately" I have just baked the ring some weeks ago. I checked, no 
frost on the chip...
Thanks anyway.
