A64-DB-2G-Rev B not booting with LCD

[negativ3]

Hi,

I have the above mentioned board with only the LCD (pine kit LCD) connected.

android ver 6.0.1 20170209 - 8GB image on uSD with Etcher.

With the SD in, the power light is on briefly (<2 secs) then off, drawing approx 300mA during this time.

With SD out, the board just sits at approx 100mA current draw and does nothing as expected.

With SD in and LCD disconnected, the board seems to boot with varying current draw up to 650mA across 2 minutes.

Does this indicate a bad LCD or do you have any suggestions what to try to fault find?

Thanks
