Gaming DSi Screen issues

Any idea on how to fix this issue?
This happen suddenly... The screens (both) got white interlaced lines out of nowhere. I was doing a NAND backup to later install unlanch and hiya cfw, but right after finishing the NAND backup and pressing start, that happened (yeah, just like that). I restarted and stills the same.

I'm not sure why that would happen randomly, but I think that looks like when the brightness potentiometers are wrong. Try removing the battery cover and spinning these with a small philips screwdriver while watching the screen to see if it gets better:
