Hello All,
This is my newest acquisition in the Samsung line of fine products.
The symptoms are a black screen, no sound, and no backlights.
The following are things that I have checked/done:
1) 120V is present at the PS board,
2) Both known fuses show continuity,
3) All caps are original OEM showing no obvious signs of leakage/bulging (hence no ESR readings were taken),
4) All diodes are showing good,
5) Measured voltages on most of the PS input/output pins (see attached pics).
The 5V are close enough I suppose, it's the 12V, 13V, and 24V that have me scratching my head as they are way too low.
As a side note, this set appears to be brand new or has had very limited usage since the inside appears to be totally dust-free as well as super-clean.
Any and all assistance will be greatly appreciated.
