Question about Televison & Video
Your error codes indicated fault in power supply feeding the main board. You have to check the output voltages of cable connectors P6,P7, and P25 prior from the shutdown to have an accurate reading. You're reference voltages are printed in the board itself. Once you encountered missing/dropped of output voltages in any of that pin-out, you may disconnect this connectors and start measuring the supply again. If the supply normalize after the connectors have been disconnected the fault is in the main board but if the supply remain the same(nothing has changed) the fault is in the power supply board. I know you will be fixing the unit yourself because you are requesting for the service manual. This fault needs to have an skills of an expert because you are going to check for voltages and also the parts for defect. Safety precaution is a must also when working in the power supply section. You have to prepare some necessary tools and test instrument.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Remove the back and check , or replace the bad electrolytic caps on the power supply and that will fix your problem.
