Plasma - Pioneer PDP- R03R - Do You Have A Service Manual?

[technoslik]

  I do have a PDP-503PU Plasma tv with the media unit PDP-R03u unit. I'm trying to locate a service manual for that unit. The TV have no error in standby (without the R03u) but as soon as the media unit is connected, the tv standby LED goes into rapid flashing. When detached, the tv return to a normal standby. Can anyone assist with a manual? :dirol:
