I think I fried an ic on my lcd board but I'm not sure. I have the lcd screen twice so I tried both of the lcd modules. None of them work well on the 'broken' board.
I get a picture, but it's all messed up with thin black lines running through it and horizontal bars.
I'm sure there's nothing wrong with my signal input or my shielding. I think it's the switching regulator because I saw sparks coming from it when I powered the screen. There's also a tiny smd capacitor where I soldered on.
I would like to know what this ic is for? What does it do and why does my picture gets messed up because of it being broken?
this is a datasheet
