I have an hitachi 60" plasma tv model #55hds69 my tv man said that i need a B+supply board but i cant find one, can you help no part # on the board

The HA01751 is the power module board. There is no "B supply board" (according to technical service manual) in the 55HDS69, which is a 55" Plasma TV, not a 60" TV. There are several "A-bus-xx" boards, there is an "X-Sus" and a "Y-Sus" board.

The B supply board is the same as the power supply and this model is only using one power supply.
If there isn't VS voltage(90 volts) feeding the Ysustainer board Q1512 and Q1515 are not turning this voltage ON due to a short in the Upper or lower scan drive boards, if there is a short in those boards; chances are that the transistors will need to be replace.
Let your TV man knows about the transistors failures or the scan drive boards. I've repaired a few of these plasmas with the same failures.
Let me know if you need further assistance. The B supply board is the same as the power supply and this model is only using one power supply.
