Well, I finally got set up and made some measurements. Thanks for your suggestions.....(See thread Sony 7 Blinks)
1st....the tv will either come up (full operation), or it will click a couple times....no HV sound, and the LED will blink 6 times....indicating +5V problem 'Shutdown'.
+5 is fine at IC504...(except that pin number 4 is at 3.4V...is it floating?). Case/heat sink seems to be at ground.
+5UNREG is at 6V.....that was the one I measured at Pin 8 of CN6504 (I think this is what you meant).
Now I need some suggestions. Your situation with T8002 seems like your HV would come up but was not high enough...so your TV was 'running' Mine does not come up because the 'safety shutoff' relay clicks in and I get nothing.....no sound or Pix.
Or maybe on the way up 5V has a hard time and sometimes comes up and sometimes doesn't.
Got any hot suggestions?
