i had a problem with the battery so i changed the epoch board
now i have no sound
any ideas please
the chips came out ond went back onto the board with out a problem.
Not a lot to choose from really. Either you've moved your e-proms into a duff board with what is supposed to be a good battery, or you have damaged the sound e-prom ~ very easy to do ~ are you 100% sure that all of the legs went fully into their slot and did not crumple or fold on themselveves and did you fit them round the right way?
If you're sure the proms are still good, why not put them back into your board and move the battery instead, with some skillful soldering?
my old board was corroded round the battery so i have changed it
the replacement was off ebay not tested.
but i had to replace the battery on this one.
