Powerbook 100 1/8 of screen is still blue after recapping

I reflowed the ribbon cable right under those lcd caps but that didn't seem to make a difference. I noticed that usually if it's a ribbon issue I should lose 1/4 of the bottom screen right and they'll show up yellowish?

The row driver has either failed, or the traces inside that ribbon cable have been corroded by the leaking capacitors. This bottom row going out on PB100 screens is now very common due to the corrosion, and unfortunately there really isn't a way to fix it.

if it's the row driver I would be losing 1/4 of the screen right? not only 1/8

Well, it’s still the row driver, just half of it. Bad line somewhere. If you're lucky, maybe there's a bad trace that isn't inside the ribbon. Take a close up photo of that bottom ribbon and look for any black spots (corrosion).

It's difficult to see but likely something inside the ribbon then. All exposed pins outside of the ribbon are connected between the 3rd and the 4th cable.

A replacement lm64p791 is hard to comeby nowadays
