– Measure across the AC pins of the bridge (BD1). No diode should read shorted.

In the world of electronics repair, few things are as frustrating as holding a failed power supply board marked with an obscure, manufacturer-specific code like . Unlike mass-market chips (e.g., LM317 or IRF540) that have thousands of datasheets online, this particular identifier points toward a proprietary board—likely used in a specific model of LCD television, monitor, or industrial display. pw.188w2.711 schematic

– Usually Q1, attached to a heatsink. Check drain-to-source resistance; it should not read 0Ω (short) or infinite (open). Replace if defective. – Measure across the AC pins of the bridge (BD1)
