Hi Shaun,
You'll need an Eeprom programmer where you - Copy the old file just in case - Blank the Eeprom then reload with fresh data where it might work, or not, if the new data is duff or from a slightly different SSB/Screen combination.
Most Eeproms can be read, blanked and reloaded on the board. Biggest problem is to get the 8 pin clip to locate correctly.
Sometimes takes 50 tries before chip can be read, other times it's a doddle and works first time.
Otherwise remove the chip and use a chip holder which always works, but then you have the issue of removal and replacement without damaging the SSB print.
It's all a bit of a pain, but possible - Chris.
