on the DEV the needles just popped off and pressed back on.. masybe there is a better way .. i also remembered where the needles were as on that 1991 panel the needles could be installed in any orientation so I was careful to put them back the way they belong.
I just gave it another go after reading your comment and made a bit more progress on disassembly. Turns out you DON'T need to remove the needles (how did you put them back in the 'right' position again?). I hope I didn't foul anything up in the process..
There are 4 prongs for each gauge that attach through the board. There was no access to remove them from the front. I peeled back and tried to pry them out to no avail. Eventually I found that I was able to push out the prongs, one by one, from behind.
Using a small bit to pop them out, I went very slowly as not to put too much torque on the board itself. Hard to describe, but the photo should clear it up:
I then gently disconnected the "mileage" and "hours" wires. After removing all that I was able to free the main board:
Upon inspection I do see that some of the original solders are showing small cracks. I assume this is what is responsible for my issue. I'll post again when I complete the repair with some more photos.
A few more questions:
1) Is there a place I can find cheap LED replacement bulbs?
2) Is there anything else I should look for or inspect before putting this back together?
3) Cadillackid ... how did you verify that the "needles" were in the correct spot again?
Hope this helps someone in the future.
