The digitizer on the screen often goes bad. Most likely cause. There’s some articles here on how to repair. Hit the search bar and enter : lexus is350 digitizer.

If you're a lucky man its the digitizer
if your like me, unlucky, then it is the motherboard and you need a new unit. I saw no point in buying a used unit so I went aftermarket 600CAD

I'm pretty sure that a replacement digitizer won't help. The new digitizer is used to repair a unit when the screen no longer responds to touch, not one that has no display.

JohnBrown7, check #4 fuse (10 amp),in fuse box located under driver side kick panel (IS 350). I pulled fuse to troubleshoot, and display remained dark. Re-installed fuse and display returned. Confirm fuse is good.

Cam across the following thread discussion about defective OEM digitizer displays;

Member RPMGraphic provided the following about black / blank screen; "-In my research it seems as the blank/black screen issue is caused by the fan on the main PCB going out & the board frys". May be what you may be experiencing if not the fuse.
