Philips LJ44-00068A TV Power Supply

Philips LJ44‑00068A is the main power supply board for 42″ plasma TVs, featuring a SMPS topology with an LM2576T‑ADJ voltage regulator and multiple electrolytic capacitors on the high‑voltage side (TOP223PN, 1M0680R). Common failure modes include blown or leaky electrolytics, cracked PCBs from thermal cycling, and shorted or degraded LM2576 output stages. First‑check diagnostics: verify input AC voltage and polarity, test output rails (+12V, +5V, +3.3V) with a multimeter, inspect the board for bulging capacitors or burn marks, and look for solder bridges on the regulator pins.[oss-gpt-20b]
