I have a 2004 Lexus LS430. Recently, with no warning, the visual display screen that shows radio stations, Heater and A/C adjustments, stopped working for no apparent reason. Any assistance or directions on how to repair and/or replace the screen would be appreciated. If it is a dealer only supplied part, any suggestions on who and where the parts can be purchased? Any assistance would be greatly appreciated. My email is: rparent61@gmail.com. Other than that problem, the car runs great and it only has 81,000 miles on it so I don't want to get rid of it. Most comfortable car I've ever owned and it has all the bells and whistles. Please contact me via Lexus Owners Club or at the email mentioned in this posting. Thank you in advance for any help you might provide. Thank you.
