The Hitron HGP180‑P240JIFE is a compact AC‑to‑DC power supply board used in OLEVIA LED/LCD TV models such as the LT26HVE and LT30HV. Common failures on this unit include degraded electrolytic capacitors causing output voltage sag, transformer winding insulation breakdown leading to shorted secondary windings, and failure of the integrated switching regulator IC due to over‑temperature or surge events. Initial checks should verify that the input AC is within spec and that the supply’s output rails (typically 12 V, 5 V, and 3.3 V) are present; inspect for bulging or leaking capacitors and look for burn marks on the regulator ICs; finally, confirm that the fan/heat‑sink assembly is clean and that any built‑in protection LEDs indicate normal operation.[oss-gpt-20b]
