help proceed avp2 flash reset needed.

hi.
hope someone here can help in solving my problem.
yesterday my proceed avp2 suddenly had all the lights on at the same time and the display is stuck at garbage letters.
nothing changes when i press the buttons or restart.

As im located in a country that has no proceed dealers within a few thousand miles and the fact that sending it out would involve heavy cash and customs formalities for export. therefore sending out might cost as much as the unit!!!!

i was wondering if anyone will help/guide me to reset the flash. im not worried to open up the unit.Is there a special way to just reset teh flash?
im pretty sure that its just the flash that is spoilt due to the electricity spiking during the storm.

thanks
