Samsung PSPF651B01A LJ44-00109A circuit board Repair Service

Professional diagnostic and board-level repair service for this Samsung PSPF651B01A LJ44-00109A circuit board.

PSPF651B01A (LJ44‑00109A) is the main power supply board used in Samsung 51″ plasma TVs and Dell W5001CHD models. Typical failure modes include a blown or tripped fuse, degraded electrolytic capacitors on the high‑voltage side, or a defective LED indicator that signals power status. First‑check diagnostics: verify mains input voltage and continuity to the board’s AC input; inspect for burn marks, swollen caps, and confirm the main fuse is intact; then test output rails (12 V, 5 V, +15 V) with a multimeter while monitoring for ripple or dropout.
