DE DMD Controller Board Help

[JohnJN]

Hey All,

Is there anyone here who would be able to unsolder the RAM chip from a DE DMD Controller board, install an IC socket and pop in a new RAM chip?

DMD controller came out of a Jurassic Park machine - had extra lines on the display while playing back the images.

I have had success with this guide.
Fixed my CP display no problem.
