Lexus Troubleshooting Questions? Ask a Lexus Expert
Thank you for allowing me to help you with this concern today and am sorry to hear that this is happening. I will have to ask you a few questions so that I can get a better understanding as to what may be going on with your GS350.
Have you had a repair shop look at this yet or made any repair attempts?
The problem with this display will be an internal circuit fault. These units have bad solder joints that "break" and need to re soldered. The Prius HUD and Highlander screens has the same issues. Here is what will be involved if you want to open it up and find the solder joints that broke...
Is this something you can accomplish?
