Why the LCD doesn't work with my Raspbian?

To use the LCD with the Raspberry Pi official image, driver should be installed first. Please refer to the user manual.
However, for the first testing, you may want to use our provided image directly.

Why the LCD still doesn't work with the Waveshare provided image?

Make sure the hardware connection is correct and connects fine.
Make sure the image in TF card is burnt correctly.
The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image was burnt incorrectly OR the TF card was in bad contact.

Which power supply should I use?

It is recommended to use a 5V/3A power adapter for the Raspberry Pi other than USB connection, otherwise the Pi may failed to start up because the PC's USB port might have not enough power.
For large size LCDs, say, 10inch diagonal or more, another stand-alone power adapter is also required to provide power to the LCD.

Description:

Meet this super ICE Tower CPU Cooling Fan for Raspberry Pi! Tower structure, 5mm copper tube, multi-layer heat sinks, 7 blades powerful fan, all the above combinations make this super radiator for Raspberry Pi. In the case of overclocking, it can reduce the temperature of the Raspberry Pi from 80℃ to 48℃. What amazing! Best of all, this cooling fan supports the new Raspberry Pi 4 Model B. In our actual use, we found that Raspberry Pi 4 has a large amount of heat. with the help of this super fan, the powerful performance of the Raspberry Pi 4 will be fully released.

Please Note:
In the heat dissipation test mentioned above, the temperature was lowered from 80 ° C to 40 ° C. The test conditions are as follows: 1-Room temperature 25 ° C  / 2- Apply silicone grease directly to the heat sink and processor chip  / 3- Raspberry Pi 4 processor

If you use the thermal conductive tape included, you can reduce the temperature from 80 ° C to 48 ° C under the same conditions. It can be seen that the use of silicone grease is better. If you want to achieve the best heat dissipation, we recommend that you purchase silicone grease.
