Sylvania BA71F0F01 026-1 power supply board Repair Service

Professional diagnostic and board-level repair service for this Sylvania BA71F0F01 026-1 power supply board.

The BA71F0F01 026‑1 is the main power supply board used in Sylvania LD370SC8S/LD320SS8M2 TV models, converting AC mains to the DC rails that drive the display and backlight circuits. Common failure points on this board include electrolytic capacitor degradation (especially on the high‑voltage input side), rectifier diode breakdown, transformer winding insulation loss, and regulator IC overheating due to inadequate heat sinking. Initial diagnostics should verify the incoming 120/240 V supply, check for open or shorted capacitors with a multimeter, inspect the board for burn marks or bulging components, and confirm output rail voltages against spec before proceeding to component replacement.
