If you are not experienced with troubleshooting complex SMPS supplies
without any available schematic and usually custom ic's with no datasheets
available, your option is to buy and replace the power board. These things
are designed to be board level repair, virtually no schematics are available
for anything inside the box except for block diagrams of the boards. Some
manufactures will provide the power supply schematic, but not always.

Hopefully they pick up the suport for older items rather than starting just
at date of aquisition like most companies.
