Power, no boot

brumbaugh

Hi,

 

Im new to the Raspberry Pi arena, but have built PC's and done quite a bit with PC's.

 

I have a Pi4, which I bought the 7" touchscreen display for it.

 

I installed everything. I have power, but no boot. I cannot even get any thing out of the monitor.

 

Any ideas.

 

- touch screen is connected via ribbon cable.

- both the Pi and the display have power and the power supply is rated to handle both.

- red LED is lit...

- SD card is in and has a copy of NOOBS on it.

 

Display is dead...

 

Any ideas? Display or OS?

 

Thanks,

Kyle

    I suggest you start the Pi without the 7 inch screen just to simplify the equation. Remember that theory in Algebra. Simplify the equation before you try and solve it. A KVM with the Pi HDMI connected to a TV will get you video with minimal effort.

     

    I have no experience with the NOOBs tool. I use an open source image hoeing software called Balena Etcher https://www.balena.io/etcher/ . Grab a full image of Raspbian operating system from https://www.raspberrypi.org/downloads/raspbian/  and use Ether to make an image to your SD card.

     

    A boot up of the Pi with the new image will confirm 1st you have a working Pi. The same SD image can be used to support the touch monitor.

    Sean is right on target. The smartest thing ANYONE ever told me (it applies to everything but it REALLY applies to computers)

     

    START WITH WHAT YOU KNOW WORKS

     

    Cant tell you how many times ive seen people put together a new pc wit all new parts, save the mouse. The spend HOURS assembling it even go through cable management and get it screwed back down before then plug it in

     

    only guarantee there is frustration

     

    strip back everything you can, then slowly but surely swap out the old stuff w/ the new.....
