I'm currently trying to convert a 846-240-H3CZZSH to function as the 860-AZ0-MLT666AMH which are 2 different types of psu for the same tv .
Now my problem is that the 846-240-H3CZZSH doesn't have the 12V line required to activate the 5VSB from the control board .. now the 846-240-H3CZZSH has three 24V lines I only need one the other two are not used.I'm wondering is it possible to split one of the 24V lines into two 12V lines and use one to send to the Control board and the other is not going to be used?
Normally I would just take two 1Ω resistors to split the 24V, but due to the design of the board i only have one output so that method wont work as I can't split one output into two or am I wrong? The 12V line is required to turn on the rest of the PSU so unless I can do this im screwed. EDIT: To be more specific if I can split the 24V into two 12V does the other 12V have to go somewhere?
Also the design of the control boards are different. I believe its just how they use the three 24V to cycle the power to the same requirements of my board (this is just different revision of the boards)
Note: on attachments
1.jpg = the difference between the 2 control boards
2.jpg = my control board
3(WIP).jpg = what i have done so far
HPIMG0545.jpg = full img of old PSU which i no longer have.
Thank you for any help you can provide.
