If you have only the PiScreen connected and no other hardware…does it work using the normal USB power? It doesn't. The problem persists.

And when it “doesn’t boot”  does the red Pi power light come on?  is there anything on the TFT of PiScreen? Yes, the red light come on, but the green doesn't. The TFT still always off.

One of those images shows the PiScreen working.. how did you get it working? Actually we've 3 devices working, but if I reboot it does not come back. If it is off, when I power on, it hardly work at the first attempt. I have to keep plugging and unpluggin the power connector many times, of course waiting for some seconds betweens these attempts to see if it is ok. Normally I try about 7 or 10 times until it boot normally.

Do you have the same problem with all three PiScreens? Yes, with all PiScreens and also with all Raspberry Pi. 

Can you send attached a photo of how you have them connected? I'm sending them. Please note that in these photos the power cable is soldered directly to the pi, but all my tests have been done isolation it, using the normal pi's power connector  (micro USB).

Hi Mark,

Thanks for your fast answer! Fortunately I solved my problem. Probably people are having the same issue as was having before. Please consider to add the solution to the instructions. What have I done? I just disabled the option "Desktop Log in as user pi at the graphical desktop", through raspi-config. I had to choose "Console Text console, requiring login (defauly)".

Best regards,
Erik
