RC070 7" LCD Display stopped working - SPI Flash
(Double post in the correct section as I cannot move the actual post - sorry for that)
Hi guys,
i have a problem with my 7" LCD Display ( 1024X600 Touch RC070 ). I used to use this screen with a tiny PC running ubuntu and it worked fine until it suddenly stopped working.
The touchscreen still works fine, but the panel stays dark (no picture or backlight at all). I measured all power rails and it seems there is voltage on all rails.
Then i measured the data transfer on the small SPI Flash and it seems that this flash does not respond, so I desoldered it and checked it with an spi flash reader. Unfortunately it could only some parts or sometimes nothing. So I assume that this flash is broken.
If I replace that chip I would need the firmware/hex file on that chip. Is the firmware running on this chip somehow available so I can repair my display?
Please see the picture attached.
Thanks for any help!

It might not be a chip issue; please try replacing the HDMI cable.
