The 6 most common reasons why Pine64 won't boot

[MarkHaysHarris777]

It's still not booting regularly. More then half of the time I get the white stripe screen. I spend way too much money on this board for it not to function. Appreciate if one of the moderators or experts (MarkHaysHarris777?) of Pine64 can give some definitive tips and suggestions to rule out other issues. When it runs it performs better on the Samsung Evo card. However when playing around with it, e.g. connecting to WiFi, browsing, testing the occasional app. It freezes for a while or indefinitely and then the white-striped screen comes. Rebooting does not resolve the issue at all then. Appreciate the help here.

This sounds like the board is malfunctioning. Please confirm, are the white stripes on the LCD 7" display, or are the white stripes on the hdmi display ? 

Are the stripes in the 'same' position horizontally?  (or do they move around from boot to boot)

Can you try another pine board with the same display?  Do the stripes follow the board, or are they persistent on the display board ?

Vertical stripes are usually indicative of a bad display board, interface connector, or bad ribbon. More often the not the stripes are the result of having a defect in the display itself; not on the computer board producing the image !

I of course cannot reproduce your difficulties; although, I am sorry.  You might like to open a support ticket and perhaps your board can be replaced; however, it would be nice if you can narrow down whether the striping is the display proper, or the pine board-- some further diagnostics will be helpful.
