What My new screen does...

So a week ago i purchased a 7" MAKIBES touchscreen for my raspberry pi 2

I went on this website for help with setting this screen up: http://www.waveshare.com/wiki/7inch_HDMI_LCD_(B)#Rev1.1_LCD_Images_for_Raspberry_Pi

Unfortunately the screen didn't work. I plug the pi into my normal monitor to fiddle with the config and install what i think are the right drivers but it still isn't working. Some people on the Amazon reviews said that the issue could be NOOBS but I don't know about that. I don't really need the touchscreen part of the screen so if its an issue with that and a solution is available that means i get no touch screen I don't mind. I wanted to prove to my family that computers can be fun and I can build my own tiny computer but in the process have made myself look like an idiot. Please help me ;-; Thanks

  • What exactly isn't working? Is there any output at all? Does the backlight turn on? How is it being powered? – Jacobm001 Mar 4 '16 at 18:44
  • The Screen just outouts the above, it is getting power via the micro usb. The backlight does turn on. it flickers turns off every few seconds. – TheDizzeePiggeh Mar 4 '16 at 19:04
  • What's the rating on the power supply? – Jacobm001 Mar 4 '16 at 19:05
  • just to clarify, i'm an idiot xD The plug that goes into the pi says: 100 - 240 volts 0.5A 50-60Hz and 24-32VA. Also Output - 5V 2.0A MAX – TheDizzeePiggeh Mar 4 '16 at 19:07
  • That is nowhere near enough power to run both the screen and the RPi. You should be using a more powerful charger for the RPi alone. I would suggest a 2A charger. Ideally, the screen would be on its own power supply – Jacobm001 Mar 4 '16 at 19:18

Based on everything you've described in the comments, it sounds like your issue is directly related to your power supply. The Raspberry Pi Foundation recommends a minimum of a 1.8. According to your comment, you have a .5 A.

.., is there a suitable charger on Amazon for my pi? Will any micro usb charger do?

That is actually one of the best parts about the USB standard. USB stands for Universal Serial Bus; what works for one, should work for any. I have two of these and have been very happy with them. But again, anything with the proper power output will work.

  • may look like an idiot saying this but just to be safe, would this one be good enough amazon.co.uk/Belkin-MixIt-Colour-Range-Charger/dp/B009S67LF4/… – TheDizzeePiggeh Mar 4 '16 at 19:42
  • @TheDizzeePiggeh: that should work fine. I would recommend getting the cable with it (Amazon recommends one) the one that came with your .5 may be in the thin side. – Jacobm001 Mar 4 '16 at 19:45
  • The 0.5A is 240V. The output is 5V 2A. This is unlikely to be an issue. – Milliways Mar 4 '16 at 22:01

Use this link to set up the touchscreen and power supply via your raspberry pi USB. Worked a treat on a variety of distros for me.

  • Welcome to Raspberry Pi! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. – Ghanima Mar 23 '16 at 22:09
