Thanks! Hey Techman, Thanks for all your help with my Sony KP-65. I sent the power supply board to Tristate Module and for $186.00 including shipping I got it back in two weeks. Reinstalled and everything works great! Could never have done this well even by calling a TV repair guy. Thanks Again, Gordie

If you have no indication of power you may have lost all of the voltages to your power supply, including the 5 VDC standby voltage. I am not sure if you can get a new G board, but you should be able to get the individual components that you need. I would look for the cause of the power supply failure first, and I think I would look at your Horzontal Output Transistor. I am thinking it is Q501, Q401 or something like that. I have repaired many of these and the HOT is most likely the problem. A shorted HOT would cause the power supply fusables to blow and the entire set would appear to be dead.
I hope this information allows you to resolve this issue. If you need further assistance please comment to this post and I will try to help you further. Thanks for using FixYa asnowman
If the IC your talking about has a designation number of IC601, the number is MX0841AB-F. Common regulator IC. Sony says that IC is no longer avaialable. You may get lucky and take out the entire G board and have ptscorp.com, or Tristate.com repair the board for you. Good Luck
