[SOLVED] Waveshare Screen not working properly and previously used

Post by skarfie » Sat Aug 11, 2018 5:24 pm

Product:
SPI 4" 320x480 (IPS) Touch Screen (GPIO)

Product Code:
MMP-0794

Invoice ID:
236864

Fault:
The product was already opened when i got it, the static bag was opened and a piece of tape had been used to re-close it. The display also looked used with scratches and the protective layer not properly applied (I've attached pictures). Yet still i decided to try to use it... Following the given steps to install onto my existing raspbian (which was fully functional), the screen froze during the boot sequence every time i turned it on (i left it for 20 odd minutes still frozen). Then i tried to reinstall the driver. Now it loads the OS but it is still very slow. The refresh rate is so slow i can see each row of pixels being updated. When i try to switch back to my monitor using the given command, it now messes up completely the display on my monitor too??? everything is rendering randomly, with text appearing over the previous text in some places... (my windows PC uses the same monitor so there's nothing wrong with the monitor, its clearly done something to the raspbian display configs).

Troubleshooting:
Multiple retries trying to install the driver as I've already explained

I'm very disappointed with this product. It was clearly used before and probably returned for being faulty, now it has been given to me! I expect a full refund.
