R pi 7" touch screen- D.O.A.- Boot failure

Former Member
Former Member over 9 years ago

Hi - just received the Raspberry Pi 7" touch screen, need some help. I can't get any sign of life at all, cannot tell if screen is defective, or me!

I have been through the help forums on several sites, reviewed the videos, even spent some time on you tube, all I've seemed to accomplish is bricking the R pi as well. It won't boot now.

  I have a new Raspberry Pi 2 model B, Raspberry Pi power supply, wireless keyboard, wired mouse, wireless wi-fi adapter (L-B link), 8 gig NOOBS pre loaded card, raspbian OS.

The display came partially assembled out of the box. I have checked and rechecked all four ribbon cable connectors, the GPIOs (#2 & 6) are jumpered properly (as shown) connecting the R pi to the adapter board.

Until late last night, the R pi was booting properly, I did have Internet access - all seemed to be in order. I came across some info regarding a need for updates to get screen working with NOOBS, things went sour from there. I presently only get a partial boot now, the screen with the four raspberrys appears, some text scrolling, then it goes to a blank screen with a small "underscore"blinking in the corner. I am unable to get a response. I have tried loading in a 32 gig card (new, formatted) with a copy of raspbian on it, I only get a red led, no green at all so this card isn't being read.  I've reinstalled the original noobs 8 gig preloaded card, same partial boot.

  I would certainly appreciate any help at all as I don't really have any idea on what to try next!

             Thanks, Kelly

    I have the same experience with the 7" screen.. I got the R-Pi working, did the updates and upgrades.  The upgrades did not have enough room to build indexes.  I purchased a larger SD Card (16GB) which has yet to boot up.  In the process of trying to get this project going I have become fluent in formatting and loading the Raspian image to the SD card using my MacBook Air.  I have one out of 3 cards that will boot.  The two that will not boot seem to go through the process; but, do not display.  I have compared the Config.txt for all three cards...they are all the same.  Where else is the video configuration stored?

     

    Thank you, Forrest

    there is two places, one in the root whe looking at it with windows, one in boot folder when looking with Linux

     

    Not all SD cards are created equal, the PI 2 needs a real class 10 SD card and a fast one if possible, it can make a massive difference in the time to boot etc if you dont follow this advise, and I have had the odd instance when the process never completes
