Okay, I found the data sheet for the LCD screen, and I figured out (I think) which pin is red, but.. I'm reflowing things and I actually appear to be making it worse??

I'm really not sure what's going on with this LCD screen. It's clearly a loose connection though because it's very much based on me pressing on the screen or wiggling it

The LCD pins are fairly sensitive to heat, especially when using irons set to high temperatures or without temperature control. Reflowing the solder in that case should be a measure of last resort. Please take a photo of the front of the LCD as well as the R pin, and if you have a multimeter try testing for continuity to R13, which should be next to the pin.

I do have an iron with temperature control, but it's too late I've already made the problem worse. In fact, I started having missing pixels and blue channel started to go out.
I'm pretty sure this is unfixable at this point and I'm going to desolder the entire LCD display
Do you happen to know where I can order a replacement NHD-C12832A1Z-FS(RGB)-FBW-3V? (Mouser is out of stock, and digikey only sells them in batches of 100)
