| SAMSUNG | SYNCMASTER 540N | Turns on but no image appears, just standby light on | Shorted smd capacitor c614 | Changing the capacitor, remove it from the board and turn it on, if the image appears, replace it with another equivalent. | MaskarenzzO |
| SAMSUNG CURVADA | UN49K6500AG | Burnt out LED bus. | High LED current with 91.2v and 500ma | Replace the LED bar (side) and replace the resistor (r9873) from 0.56r to 1r, the current drops to 88.2v and 220ma. Note: this model tends to burn out the LED bus and also the diffuser acrylic. | Evando Viana |
| SAMSUNG | LE40R86WD | When it heats up the image goes out. Sometimes it turns off, locks or freezes the screen. | Defective power supply capacitors, especially the electrolytic ones inside the oscillator ci cage | Edson SP | |

| SAMSUNG | LE22C450E1 | Doesn't start. led blinking | Capacitor shorted to the rf input | Pablo | |
| SAMSUNG | S27F358FWU | No backlight | Check replace 60v 300ma sot-23 2n70002k | ||
| SAMSUNG | UE46F6320AW | Turns on and off, power supply goes into protection | By deactivating the protection (r bridge qs861), the power supply starts and does not turn off. LED strip failure | Pablo | |
| SAMSUNG | LN32D450 | Does not work, stand by LED on activates power key, LED blinks but does not turn on. | Check voltage on ic205, 1.5v. absent. check possible short in c 1020, 1115, 1141 | In my case, c1141 shorted. replace and go for the hug. | arock |
| SAMSUNG | 632NW PLUS | Doesn't start. Sometimes the LED doesn't light up or it lights up dimly. if turned off for a few days, it works again for a while. | 5.1v and 14v line with varying voltage | Replace the 5.1v (c109/c110 1000μF) and 14v (c113/301 820μF) line capacitors. all four were looking good and measuring ok. I just replaced it and it resolved it. | PIXEL ASSIST |
| SAMSUNG | UN48JU6020G | Power supply secondary completely dead/turning off after a while. | Cold solder on the main transformer of the power supply / if pin 1 of the icm801 has less than 170v, the polyester capacitor cm847 will be leaking. | Carlos Araújo 82 9 93677063 | |
| SAMSUNG | UN50TU8000G | Burning the LEDs | Backlight with voltage above normal. | Solution: remove r901 from 2.4Ω. and don't worry, it won't burn the LEDs again. | Eletrônica Evolução |
