Just powered up a brand new cobra with 7 inch TFT.
I managed to MFDeploy the latest code, then built the Graphics demo (7 inch) and deployed that.
The screen remains blank, and I noticed after a while that the edge was getting VERY hot!!. This is the brown ribbon and surrounding screen area.
To get this far - I have done as advised and connected a 5 V regulated power supply with a link between Vin 6V and 5V In/Out - as I didn’t have a 6V power supply with enough power :-O.
Apart from that - its straight out of the box (bought in the UK not direct).
All I did was to screw the Cobra onto the back of the LCD, and connect the flat cable - yes its connected correctly.
Any ideas please ???. Looks like a duff display to me :-O.
