Hi,

I’m having trouble getting the 3.5-inch LCD touch screen working with my Pironman 5 setup. I followed the official tutorial at [https://docs.sunfounder.com/](https://docs.sunfounder.com/) step by step but the screen is still not working.

**Hardware:**

- Raspberry Pi 5 Model B Rev 1.1
- Pironman 5 case
- 3.5" TFT LCD Touch Screen (ILI9486 driver IC, 480x320, resistive touch, XPT2046 controller)

**Software:**

- Raspberry Pi OS 64-bit (Debian GNU/Linux 13 Trixie)
- Kernel: 6.12.47+rpt-rpi-2712
- pironman5 service v1.2.15

**What I did following the tutorial:**

1. Removed the RGB jumper on the IO Expander as instructed
2. Disabled RGB LED service: `sudo pironman5 -re false` + restarted service
3. Cloned and ran LCD-show: `sudo ./MHS35-show` — installed successfully, fb\_ili9486 driver loaded correctly
4. `dmesg` confirms: `fb_ili9486 frame buffer, 480x320, spi0.0 at 115 MHz` and `fb0` created

**The problem:**  
The screen stays completely white — no image at all. Writing random data directly to `/dev/fb0` with `cat /dev/urandom > /dev/fb0` produces no visible change on the screen. The desktop works fine on HDMI but never appears on the 3.5" screen.

**Question:**  
Is there a known issue with this setup on Raspberry Pi OS Trixie (Debian 13)? Is there a specific configuration needed to route the display to fb0 on Pi 5?

Thank you!

The driver you are using is for the 3.5-inch TFT screen. Please test it with this driver instead:

```auto
sudo rm -rf LCD-show
git clone https://github.com/sunfounder/LCD-show.git
chmod -R 755 LCD-show
cd LCD-show/
sudo ./MHS35IPS-show

```
