Help Marantz CD-42 MK II died

Hi,
My Marantz CD 42 died
When I put a CD it doesn't speen the CD
When I turn it on with the stop & play buttons pushed (I think this is test mode - I dont have the service manual)
I get code "P122"
Does anyone know what this code is ?
I don't have the service manual so if you have it I will glad if you can mail it to me
also I will be glad to ear any other idea that help me bring it a live

Thanks
Zachi
