Howdy folks,

an update on the CdS thingies: I've managed to remove them after lifting off the finder prism and unsoldering them.

The photoresistors come in a gold-coloured metal casing and bear the label CL1323, which I assume to be the type, although I found nothing in a net search. Anyone know these or where I can get 'em?

I checked them out under a loupe, and *one* (not both) had corrosion on the traces. That pretty much explains everything, tho I do wonder why only one is affected.

I checked the resistance under daylight (overcast day, ca. 500lx), and got ca. 6 kOhms on the good one, and only 1.2 kOhms on the corroded one! Figures...

Now to get a replacement... hmmm.

Regards,

--Roland
