Hello, 2Big2Fit,
Asked this once before but I'm sure you didn't have my e-mail address. It's in the forum now. Can you provide me with a name and address for this fellow. It sounds like the way to go for me. I'm a little too shaky for fine soldering work.
Thanks again,
Pete O.

Just fixed my display! Been bugging me forever. I had the 2nd variation. Some of the resistors came out of place a little, but I had so much solder there that the multimeter confirmed no resistance. After a second of letting it "warm up" it turned right on bright as new. Great info! Thanks again!
Now I guess I need to tackle led-replacements.
If i did it again, I'd cut a very thin piece of electrical tape to place over the row of resistors to keep them planted while I worked. They probably wouldn't have moved if I had done that. Still, its very easy even if you are not a great person with a soldering iron. (I would say I'm about average-slightly experienced.)

I found that one end of the 241's were not attached and the other end was holding them on the board...if you try to re-solder the good end they will move around, but if you solder the bad end first, nothing moves. I would imagine you could test the "good" vs "bad" ends by using a ohm meter to test resistance between the 241 and the board. Just an observation...I've been thrilled with my working display just like everyone else here. I have lost almost all of my bulbs now...working on the resistor+LED install project down the road.

Take it to a local TV repair shop. They can solder those back on in a snap. That way there wont be any shipping charges, and you can slide it back in the car and test it while your there.
I recommended that to another person and it worked out well for them. He really like being able to test it after it was resoldered.

The backlight bulbs all run in series off one circuit;
Radio Shack sells a 60ma bulb that is very close to the stock 70ma. I recommend replacing all of those at once...
The LEDs are controlled by the buttons each one represent but I'm not sure where that circuitry goes. If you have a few LEDs out try replacing them...
And that's all I know!

I actaully found a much better source for the stock incandescent bulbs:

Make sure you replace all of em at once.
Heck yeah you can replace em with LEDs! I've done alot of em for Forum members...
It adds color to the Passenger dial sweep too if you do it right:

Very informative thread! I did mine today and I'd like to add:
Update the equipment list on the first page, to reflect the sockets needed to do the job. Was missing 7mm (the nuts which hold the hvac unit to the dash) and 3/16" (the screws that hold the control unit together). As a previous poster mentioned, you have to have a thin-walled socket. My standard Craftsman w/ a 1/4 drive worked OK.

First time posting on this forum.
I just picked up my 2000 C5 from the lot yesterday. (It was used in a new tire development wear test at my company and was in excellent shape.) It wasn't until after I read this thread that I realised this is an issue I can repair myself. Thanks for all the info as it helped me in my decision to buy the car.
Question: Could someone recommend the best type of soldering iron (brand name and model) to do this intricate work? I do own a Weller soldering gun, but after reading thru all of these posts it seems a smaller solering iron would be best.

I just traded my 93 C4 for an 02 C5. I was so enthraled with the fact that I was finally getteing a C5 that I over looked the little things. Well when I finally came down I noticed the display was dim. I researched it and discovered this thread. I liked the way you posted pictures and setp by step instructions. Thanks, you rock!!!!!
