Hello,
I am looking / wondering if anyone knows where a good firmware download link is for a LC-60LE640U, the sharp support sight says the screen is archived but offers no links.
I see backlite is active,

any assistance is greatly appreciated. -
Hi everyone,
I've got a little "problem child": my Dell Latitude 7420 2-in-1, which had a faulty mainboard.
I replaced it, but ever since, the touchscreen no longer works — and honestly, I’m running out of ideas…

I've tested all the voltage rails coming out of the power supply and they are "normal" for this model (PS_ON & DIM go high when turned on, BL_ON & 3D_ON are close to zero due to backlight power flowing through the mainboard, 5VSB is 5V, and 12V is 19V, which is apparently normal for this board).
Basically, I get similar results to Garry in this post: https://www.badcaps.net/forum/showthread.php?t=80346
So, I've ruled out the PSU for now.
