TV: Toshiba 46XV645U
PSU: PE0702A, V28A000962A1 (purchased used, appeared to been have been previously repaired and lasted 2 years)
Issues & History:
- No Power, No Click, No 5V: Tested and found Fuse R851 Open. Replaced R851 and Voltage regulator Q880. A well documented problem and it did bring back some life back to the board because after plugging, the relay engaged and I got 5V but still no 12 or 24V. No red light, nothing happens when power button is pressed.
- Confused, I obtained a repair kit which replaced a bunch of components. I also replaced the capacitors at c820, c821 as they seemed slightly bulged. End Result: No Difference - same issue.
Current State: I get 5V. I hear the relay engage. I do not get 12v. I do not get 24V. I do not see a red light. I press power button and nothing happens.

Ideas? Where have I failed?
