If the PICAXE and other compnents aren't damaged you should be able to use the board without IC2 fitted.

First step is to remove IC2, then see if you can download into the PICAXE.

Assuming the driver was an L293 it is VERY hard to damage them as they are thermally protected.

Have you perhaps applied over 5 volts to the PCB and cooked the Picaxe as well?

Are you sure it is the L239 that has gone, and not the PICAXE? Are there any signs of damage (melted tracks?) anywhere on the board?

works fine..thanks for the help

Great. As Rick points out, both the PICAXE and L239 are tough chips.
