KAS297B Lenses

[Greg_D]

Does anyone know a source for the subject lenses?  I'm trying to replace one that is very hard to see thru due to age on the unit.

Greg,

you might try a search for display lenses or face plates...

Some times BK had them for sale...we have a new BK guy around here as well...

Other times LCD displays were being sold...

This search may go about half the distance to where you want to be...https://mooneyspace.com/search/?&q=Display lenses&search_and_or=and&sortby=relevancy

Best regards,

These aren't quite as good as a new OEM, but they are readable: https://www.ebay.com/itm/KAS-297-KAS-297-KAS297-Amber-Lens-Free-USPS-First-Class-Shipping/202711792314?hash=item2f32907aba:g:l-cAAOSwr6hdClCu

Thanks Lance.  We tried one of those off eBay and they weren’t clear enough.  I might try to find some thinner, more transparent material and cut my own.  I’ve read reports of people paying up to $9K to get these things repaired.

You might give this guy a call with the dimensions. His after market lenses are much better than what I've seen elsewhere.

I've used their lenses to replace delaminated ones on multiple devices. There's a disclosure because they're not PMA parts, but the avionics shop had no issues installing and signing off on them.

Thanks for the lead on this.  $15.00.  The ones on eBay were $33.00!

Glad to hear it - shoot us a picture of it once you get it and get it installed.

Thank you! I was also looking for a new one. 

On a separate note, does anyone know how to adjust the display dimming on these? Mine is very dim and difficult to see during the day. I tried cleaning the photocell but no luck. 

Thanks

If the photo cell doesn’t do an obvious change to the brightness...

Might be time to discuss getting it cleaned, or swapped out...

Probably is in the plan as designed... sensors often have a useable lifetime... easy to swap out at an avionics shop...

We can wait for our usual avionics guys to stop by... or go on the hunt to find them...
 

Alan is in S. jersey, and know a lot about these things...

Best regards,
