thank you for the reply
digiprint has nothing in stock and either does roland (the only place they would get it from)
the other led-print.com is in indonesia
regardless of what part you request, they will claim to have in stock, until you send your money
if no one is "parting out" an fj, i suppose it will be time to break out the oscilloscope and either repair the existing board or make a " break out box" based on the roland ribbon cables
thanks again terry01
