  1. Just to clarify the problem, Q1) does the radio work? Q2) On the center display, do you get any pictures? If the answer to Q1) is yes, and the answer to Q2) is no, then I have lived through this problem. The least expensive repair is to replace the screen on the nav unit (about $200 for the screen if you order it online, you remove the nav unit, replace the screen and reinstall the nav unit yourself). However, it could also be the nav unit and that is a lot more expensive. I found one from a salvage yard for about $1200. This issue is something that Lexus should make a lot less expensive to repair, if they want to keep a good reputation. At the time, the Lexus dealership said a new unit was unavailable and a remanufactured nav unit was over $5000, without labor! So it's really important to get the diagnosis correct!
  2. Thanks jlang for your instructions and pictures. Mine was the same #1 trace. I repaired it following your instructions and it's been working for 2 months now! One thing I did differently, was to reinforce the back of the flex cable with some epoxy. Circuit writer ink broke while I was messing with the flex cable. With a little reinforcement on the back side, the repair was solid. Thanks for your help! I didn't know how to troubleshoot the screen, and your ohm measurements were right on!
