service manual for Sony PVM-2030


i am in the service process of my newly purchased Sony PVM-2030.

basically, i have two.

one can only work for about 5 second and shut down by itslef. i guess it is something overrating.

second one response nothing but i know one fuse 6.3A/125V is blown.

they look very complicated and difficult to service as everything is packed in limited space.

i would appreciated to have service manual so i could restore them to life after 23 years.
