A13-LCD10TS broken?

[ragupo]

It seems my A13-LCD10TS is broken.
I cannot boot into any image (5or7) anymore, with the touch screen part attached. Detaching the touch screen module from the lcd  itself immediately makes the problem go away. But leaves me with a non-ts A13-LCD10TS.
I get a lot of output from the board, but im unable to make any of it. This attached part seems interesting though.
Maybe some of the experts in here can help pinpoint the problem or give any advice?
(I had to cut parts out to make it fit the max 20000)

Hey there,

Was the touch screen working initially? Or the problem was there since day one?

Please test with the latest Debian image https://drive.google.com/file/d/0B-bAEPML8fwlX2tYS2FmNXV5OUU/edit?usp=sharing and remember to configure the video output with ./change_display_A20_OLinuXino.sh

I also recommend you to test with the image for Android (just for hardware testing purposes) here: https://docs.google.com/file/d/0B-bAEPML8fwlc1F6TkNIcmlWcjQ/edit?usp=sharing. Note that the method of downloading the Android image to a microSD is different than Debian and might be found here: https://www.olimex.com/wiki/A20-OLinuXino-MICRO#How_do_I_write_the_official_Android_image_to_a_micro_SD_card_for_my_A20_board.3F.

Finally, make sure the connector is properly plugged, it is possible to plug it reversed or to misalign the small connector of the TS component.

If the problem persists please send an e-mail at support@olimex.com

Best regards,
Lub/OLIMEX
