Strange screen artifact

Former Member
Former Member over 10 years ago

Hi,

I have 3 Pies

#1  1x Model B with 2 USB ports

#2  1x Model B+ with 4 USB ports

#4  1x Pi2  (there is only one model, right?)

 

I have used all 3 to run Openelec.

#1 works perfectly

#2 and #3 also run openelec but they both show an artifact on the top right-hand corner. It seems to be a miniature version of the colour screen that is shown right after the Pi wakes up but before it runs an OS.

 

Has anyone else seen this????

 

Cheers,

Nick

    It's a low-power warning. It shows up when the 5V supply goes below 4.65 if I remember correctly.

    Thank you very much Ragnar!!!!!

    That's exactly what was happening.

     

    I've had issues many years ago with crappy USB leads, so I started buying one at a time from different ebay vendors until I found one that had cables that could carry 2,000 mA and then I bought a dozen or more from him, tested them each and gave most of them to my friends who were complaining about slow charging times.

    (I also bought a bunch for myself)

     

    So, when I saw your message, I collected a few of my 5V, 2,000mA power packs and tested them (as well as 2 different cables) with the Pi2.

    Voila!!!

     

    One substandard cable in the bin later and the Pi is happy.

     

    Thanks again,

    Nick
