hi guys, i have a touchscreen linitx 7" screen, it worked before i took it out of it case.

then once i had it assembled out of the case just on the table a few months later, i get a flashing red light on the main board see pic:

basically i get power to it but nothing on screen just stays black with no backlight,

if i use the remote to turn it on all i get is the blue light on the button board come on, that is all. like this:

has anyone had this problem before? or know what is broken?

thanks in advance
