Hello @redstone8415 

To resolve a white screen issue, check the LTDC Clock setup, and ensure the timing and polarity settings are correct.

Ensure also to use the correct physical connections and verify the jumper settings (JP3 and CN4 are set to "on") following the Getting started with the STM32F429 Discovery kit (page 9)

For LTDC configuration, refer to this application note: AN4861: LCD-TFT display controller (LTDC) on STM32 MCUs - Application Note

As stated by @mathiasmarkussen , why don't you start from TouchGFX designer based on TBS available and select STM32F429-DISC board as shown below?:

Try starting your project from the TouchGFX Designer instead. A complete Board Setup is supplied for STM32F429I-DISCO. You can than modify according to your needs from there - or you can analyze the project to figure out what you need to change in your own project if you prefer.
