LCD touch panel emits low power
#1
I think that my LCD Touch Panel is defective (I hope I'm wrong). 

First of all I've to say that I owe 2 Micro SD cards. The first one has the "Lollipop Beta 2 (LCD Version)", and the second one has the "Lollipop Beta 2 (HDMI Version)" both downloaded from the website.

Here is an image that shows how my LCD Touch Panel is connected to the board. (My mobile camera is ashame).

As you can see it's all correctly connected with all the pins down... The thing is that I've tried both HDMI Img (on my living room TV) and LCD Img on my LCD Touch Panel. Here i'll show u the results.

HDMI (living room TV):

LCD Touch Panel:

As you can see the image works in both screens, but the LCD one can barely be read. I can assure you that i got to the "desktop" on both applications and that the Touch Panel works (I know it isn't connected in the posted screens, but I did test it before), but I don't get why it emits that low brightness (I've turned the Android brightness to max already and it's not that).

I would appreciate any advice, cause I don't know if I am doing anything wrong.

From your photo, looks like the LCD panel backlight didn't lighted up. For installation procedure, here is the link: http://files.pine64.org/doc/guide/PINE64..._Guide.pdf

Still not working, I followed your installation procedure which is exactly as what I tried many times before.

Already tried it, can it be something else?

If install properly, no sure whether the backlight circuit on Pine A64 board or LCD panel itself having issue. Please contact Pine64 support, http://support.pine64.org, and issue a support ticket.
