TV keeps blinking 2x in a 5x cycle | TV came with standby protection | First do the test: remove the flat cable from the power supply board that goes to the motherboard. the TV turned on the backlights. then remove the ps-on track from pin 6. the tv will open the image and backlight normally. defect: changing mosfet smd that goes close to the motherboard connector: q206 (p-channel) | Karen |

Flashes standby and hits the relay repeating the process... power supply arm the LEDs normally when isolated from the main. | Mosfet smd channel n 035n40 screen printing qm854 shorted pcb power | The MOSFET was replaced using compatible SMD D4185 taken from various scrap Samsung power supplys. resolved. Note: this TV goes into protection by hitting the relay due to different types of problems, it is good to evaluate it carefully! att, | |

Only standby, when pressing power it did nothing and turned to standby | After analyzing the TV boards and finding nothing wrong, I decided to open the one conect for analysis and located a heating in the middle of the board. When measuring, I found a shorted capacitor next to IC207, I removed the c267 capacitor and measured it outside, finding a short. When turning on the TV without it, everything worked perfectly. | Eletrônica Mirage | |
