In the time that I’ve had my 2006 Lexus IS350, I’ve had a couple issues with the touch screen. One issue was the notorious frozen touch screen issue where the digitizer has failed. The second issue was the head unit screen going completely blank. The screen was totally black even though the car was on. This issue had a quick fix, which was to check the interior fuse box. Thankfully that took care of the issue before I had to go further with additional troubleshooting or worse, a full head unit replacement.

The touch screen suddenly stopped working on my Lexus IS350. After realizing a repair with a conductive pen wouldn’t work, I decided to replace the whole digitizer. At only $20 for an aftermarket one online, I thought it was a no brainer.
