There are two pieces to the climate control. One is the main board and the other is the display. The display is about $800, dealer wants about $1200. The main board is about $600, dealer is about $800.
Well, unless I missed something with the several climate controls I have laying around: they just use plain light bulbs and not LEDS. They use the tiny little ones used in here and there...
If you are up for a bit of fabrication, I don't see why you can't use LEDs.

The display is florescent so it needs a high voltage supply, that would be the first thing I would check. I have a dead display that I will be working on in a couple of weeks will see what kind of success I have.

The problem with the display was in the board. Repaired the problem and the display works just fine.
Can you elaborate a bit?
What/How did you fix?
Would it be a common fault or a fluke?
Testing/Diagnosis procedure?
We want to know!

I did a side by side comp. of the bad board with a good board and found a bad transistor. That transistor looks like its part of the chopper circuit for the high voltage supply that the display needs to light up. Its common to have the display to go off, having a bad transistor is just one of the reasons. Damaged traces from leaking capacitors is the other.

There is smaller board for the display as well and it also has those problematic caps. on them...

The display half is $1000 list, the control board half is $800 list.

There are 2 that are in the chopper circuit one NPN and one PNP. Needed to replace one NPN on one board and the PNP on the other.
