Replacing instrument cluster

what tools were required to remove the IC??

I learned a few things. Contrary to some thoughts, pushing out a new update with a different IC will not brick your car. Also, contrary to posts I have read on these forums, pushing a new update to the replacement IC, will NOT make it Sync to your MCU. So, going with Buenos suggestion, I used my old motherboard and married to the new screen. There were about 8 small torx screws and a couple of ribbon connectors that needed to be removed. After that is was plug and play.

I wish Tesla would start selling parts, this job was super easy and no need for a computer reboot nor a need to throw away a perfectly good motherboard. BTW, that goo was terrible, but simple rubbing alcohol took it off. If/when the MCU screen goes, I plan on doing the same thing- very quickly. That goo is horrendous! Posting a couple pics with part #s in case anyone is considering it. I saved $1260 by doing it myself.

Torx bit (not sure what size), interior trim removal tools (harbor freight has them), inflation bag (Home Depot- but I just used a rigid small box to push into the cavity above the steering wheel to beep the dash high enough to get at the screws). You will need a smaller torx bit to remove the IC screen from the motherboard. Also, alcohol cleans up the goop really well.

Looks like almost there. How do I remove this ribbon form the mother board? This makes me super nervous

Pull up gently on both sides of the black tab above the ribbon. That is a flap that clamps down on the ribbon.

So I’ve replaced my cluster and now I’m not getting power to it? What did I do wrong? I tried just putting in my old one with the glue damage and same thing no power

Sorry I’m still learning how to post on here.

are you sure the ribbon cable is seated correctly? if its not then you will not get any display on the screen. Looks like the board has power based off the light glowing but no display I would double check the ribbon cable.

I still have my old one at home Ill pop it apart and take some pictures. Give me about 3 hours till then.

i actually purchased one off of eBay and I didn’t mess with it at all other than just plugging it in.

This one I bought off of eBay and it has never been taken apart. At the very worst I should be able to get power to it giving me some kind off error code. I was planning on switching out the motherboard

I just received a new update

If it wasn’t for this forum I wouldn’t of gotten the courage to attempt to fix this. I just saved myself $1300. Thank you everyone

I’m super stoked. Dude thank you so much for trying to help me out. I’ll be reaching out next time I need something else lol. I was literally loosing sleep over this especially seeing other people doing it so easily. I actually don’t know what I did to fix and I don’t care lol

Glad to be able to help out! I think my next post will likely be the MCU screen, as they seem to go to crap pretty often. They are still pretty expensive used, but I saw someone was able to purchase one directly from Tesla for about $800, which is the price of a used one...

I will definitely be following.
