There are 40 pins on Raspberry Pi, but there are 26 pins on the LCD, so you should pay attention to connecting the pins to your Pi accordingly. Install the touch driver The RPi LCD can be driven in two ways: Method 1. Install a driver to your Raspbian OS. Method 2. Use the Ready...
This is not power problem, i'm currently running my rpi 3b+ with 5A 5.2v power supply(testing with 4 LTE modems, increased voltage to avoid drop in wires to modems, at rpi terminals multimeter reads about 5.15v average(i have also shorted main power with usb pins on rpi to avoid rpi...

Are you sure you are looking at a Pi3B and not a Pi2Bv1.1? Are you sure the SoC is labeled BCM2835 and not BCM2836? What is silk screened on the PCB just below the GPIO pins (the model and version is printed there)? Note the OP already gave the silkscreen version number and ...
Also the connector used for the touch screen uses 26 of the 40 GPIO pins.Being of the mind set of wanting to improve things, I can see three things that would be of benefit: 1) Adding a fan for cooling of the heat sinks and better air flow. 2) Access to the connector’s GPIO (...
There is an upper limit in how fast the GPIO pins can be controlled, which limits the frame-rate. Raspberry Pi 2's and newer are generally faster. Even with everything in place, you might see faint brightness fluctuations in particular if there is something going on on the network or in...
Important Notes : : Please plug the screen on Raspberry Pi's GPIO pins correctly( as the picture) , otherwise the touch function will be damaged. Features 320×480 resolution Resistive touch control Supports any revision of Raspberry Pi (directly-pluggable) Compatible with...
