You make a good point. When I went out to buy my new PSU I carefully selected one with removeable leads.

I had a choice.

Of course I made the wrong choice!

All this is completely news to me.

But, it s all about learning, which is supposed to be good for us.

Thank you again.

Dave, Congratulations, I am impressed. You have got it. I have wiped and reloaded my SD card again in case I have messed it up. But, critically, I have also fitted a different USB cable (from my wife's phone, my iPhone 5 has the wrong kind of connector). This is what has fixed it. I had no expectati...

Dave
I have been out and bought a 2.4 amp PSU and that made no difference.

What does the coloured symbol in the top right mean?

I will reload the SD card.

Thank you.

Dave and rprandom

Sorry, I should also have said that the red LED goes on and off. It might could have a regular pattern rather than just flashing.

If I don't press the shift key they whole thing just goes back to the start of booting anyway.

Thank guys

Dave, You are giving me hope. Thank you. Yes, I have the multi-coloured (miniature rainbow square) in the top right. What does it mean? The PSU I use is the one supplied by Maplins in my Raspberry 2 kit which worked fine. It says it output is 5v at 2.1 amps. Any good? Do I need a bigger one - how bi...

Thank you replying. I wiped a Micro SD using the SD site and then carefully downloaded 1.9 onto my computer and extracted it to the SD. I put that into the Raspi3 and powered it up. The outcome is identical. Insatalling the OS reported successful. The NOOBS window listing the operating systems avail...

Friends I am quietly going mad. I have a Raspberry Pi 3 and I simply cannot get it to boot. I have used a downloaded SD and bought two new NOOBS cards. To cut a long story short I end up in the same place every time: The screen fires up and the long listing scrolls through on the left. It then flips...

Having struggled to load Rasbian in my new Pi3 I have managed to get a full 100% . I did that by slotting the SD card in and out a few times to clean the contacts. Maybe that was nothing to do with it but I got a result. After loading then it goes to a screen headed "NOOBS v1.8 Built Feb 26 16" wher...

Yes, I thought that was going to be the explanation. I have tried everything I can think of, and I am not a complete ham, and it won't play.

I will just mend it with a new one.

Thank you.

Friends I hot re-connected my Pi to the display and the general background colour went red/pink instead of the normal white desktop screen. It is as though there is a complete red/pink gauze over the whole display. Everything else still works fine and is more or less readable but I cannot find any w...
