I have the large Mainz PC board thatís under the removable black plastic shelf. I believe a motor died and when that happened a component or two died on the main board. At the time I bought a new main board from Melco. But I still have the old PC board. Is there a place that tests and repairs the main boards? Iíd live to keep it as a back up if itís worth the repair cost.

Thanks for your help
