I am having trouble with my ATC unit.  I did manage to find some information to repair the dimmed LED display, which I did and now works great.  But, most of the lights bulbs on the unit are burned out.  I looked at them, and they are nothing that I have never scene before.  No marking what so-ever on the bulbs or anything.

Does anyone know where to get these bulbs?  Or better yet, if they have an LED replacement for them....

I found a place on eBay that will do an exchange for the unit at $100.  But, I would rather save the money and do it myself.  I am pretty darn good with a soldering iron, and that is all it would take (once I have some replacement parts!).

I have an HVAC module that was replaced,The problem was it was bright at times and very dim at times .they determined it had cold solder joints.I have no idea on fixing it but would be willing to part with the whole box for 100.00
