Wonderswan dead pixel lines

[fredJ]

Does anyone know how to fix dead pixel lines on a wonderswan console? I have one Color console with a dead vertical line, and one console with a big dead horisontal line (probably like three lines).
Any directions? I tried a bit of heat , as you would on the old Game Boy, but it doesn't seem to do anything. Not sure where to apply heat either.
I have fixed many old game boy consoles with dead pixel lines, by the way.
The vertical line is constantly purple, and the horisontal is in a dark black/grey shade.

thanks

Check and see if the connectors are corroded, that is what killed one of my Gameboy Color systems, maybe the Wonderswan is similar.
