[rescue] Sparcstation Voyager

[HHA]

Dear all,

some time ago I got a defect Sparcstation Voyager, which I want to try 
to revive now.

Main faults are:

- Faulty internal DC converter: 3.3 V and 12 V outputs seems to be 
stable, but the 5V voltage is rising slowly after power-on until the 
sparcstation is shut off (by an internal overvoltage protection ?) when 
the output voltage is coming near 6V. Maybe its a defectB  electrolytic 
capacitor, but it is hard to debug without a schematic.

Does anybody have a schematic for the 40W DC-DC converter (Sun P/N 
300-1234 == FDK CEX165-00) ?

- The LCD display (Colour TFT) is looking dead, does not show anything; 
at least the banner and some error messages should appear.

Does anybody own anyB  docs about the LCD's internal structure ? Are 
there any fuses (and where ?), which should protect the LCD?

Many thanks for helpful replies,

Heinz Haderer
