Korg Poly800/EX800 Users

It is one toshiba chip that needs to be replaced.
It is mentioned in the service manual should all work but no sound be heard from the poly 800. Its on the main board. The number of the chip is on my schematics . I cant gurentee it but it is in the service notes. apperntly enough of the same prob happend that this was a major note. Im not saying this is or isnt .But Ive bought a few poly 800s and its one or the other chips for the output control to the sound source of the poly 800....
If interested Ill get the part number and email the service note. If you can solder very finely its not a big chip. I dont know if I have a spare im pretty much building up parts to keep for me when this happens again. SinceI have three and I bought some extras let me see what I find out when I look through my parts bin I collect toshiba chips and major processors for the poly .Im now starting to with the juno. I will sale poly 800 keys now and some other stuff .This will also change I bid on every broken one I can find...
Peace
