Default Telefunken P540NV schematic

Hi,

Is there any kind soul that could help me with the Telefunken P540NV
schematic?

The problem with the TV set is that the power supply randomly burns the
power transistor. It is a BU508A. The output voltages are right, the
transistor does not run hot, just burns after 3 hours to 3 weeks.

Thank you,
Cirip
