Samsung Freestyle Projector No Power Fix | LSP3B Board-Level Repair | Full Teardown

Samsung Freestyle LSP3B Portable Projector – Completely Dead, No USB-C Power | Full Disassembly & Power Distribution Board Repair This Samsung Freestyle LSP3B portable projector came in 100% dead: – No power – No LED – No USB-C power negotiation – Even the USB-C power meter would not turn on In this video, I perform a full disassembly and step-by-step power failure diagnosis, turning this repair into a complete teardown and troubleshooting guide for the Samsung Freestyle projector. The disassembly alone is extremely time-consuming and complex. Once opened, the internal design reveals a puzzle-like construction: Around four stacked PCBs A cooling fan and heatsink placed between boards Multiple flat ribbon cables and wiring harnesses interconnecting everything The main power distribution board located at the very bottom, meaning everything above it must be removed first After fully stripping the unit down, I traced the fault to the main 20V power rail, which was shorted directly to ground. Before voltage injection, a detailed visual inspection revealed the real culprit: ➡️ A discolored and cracked capacitor on the power distribution board. Once the faulty capacitor was removed, the short circuit disappeared. Since it was the only capacitor in that part of the circuit, I replaced it and moved on to testing. The moment of truth: USB-C power meter powered on Power Delivery controller became active 20V negotiation restored successfully Reassembly took even longer than the teardown, but after a full rebuild, the final test confirmed: ✅ Projector powers on ✅ Power rails stable ✅ Repair completed successfully This video is ideal if you are: Repairing a Samsung Freestyle LSP3B projector Diagnosing USB-C PD power failures Learning short-to-ground troubleshooting Interested in real-world, professional electronics repair workflows #SamsungFreestyle #LSP3B #ProjectorRepair #USBCTroubleshooting #USBPD #NoPowerRepair #ElectronicsRepair #BoardLevelRepair #ShortToGround #CapacitorFailure #Teardown #Disassembly #PowerRail #PortableProjector
