Hello,
Im having a HD10000 with burned diodes D23 D29 and two others and i need help finding out how those are connected,
because the pcb is very badly burned.
Or maybe someone could help with schematics or a service manual.
Also i can't identify the diode.

first of all scrape the carbon from the affected area since it tends to generate electrical resistance on the components to be installed.
I agree. ALL of the carbonized material. You should have nothing remaining except for clean fiberglass when you finish, even if it leaves a hole in the board. Failure to remove it can lead to it continuing to burn, doing even more damage.
The diodes form a bridge rectifier that feeds the regulators. You may be better off using leaded diodes instead of using the SMD versions.
