Brand | Model | Fault | Detailed Problem | Solution | By |
---|---|---|---|---|---|
SAMSUNG | UE40H6200 | Does not light up, the LED blinks. low voltage 390v (+/- 320v). 15v is missing on pin 8 of the icp801. | Transistor qm821 (zg) or (7cw) with leakage | ||
SAMSUNG | UE55MU6105K | The LEDs turn on and off but no image | Bad contacts in the flats | ||
SAMSUNG | UE40D6510 | The TV doesn't start and keeps restarting. | Reflow the mainboard | ||
SAMSUNG | LN32A450C1 | It turns on standby and does not turn on via the button or control, it flashes briefly but does not turn on. | Secondary power supply with capacitor cb852 (1000uf x 25v) swollen and some cold soldering. | This capacitor had already been replaced previously, perhaps a chronic defect, so I added a 35v capacitor just in case. | PIXEL ASSIST |
SAMSUNG | LE37S73BD | You lose the tuned and memorized channels. when turned on, it searches the channels again, | Defect in eeprom ic3004(m24c32-wmn6tp). defect possibly due to ripple voltages from the power supply, | Check power supply voltages and capacitors. reprogram eeprom | Pascual |
SAMSUNG | UE46F5000AW | Does not light up, restarting and never turning on | See cold welding in the power supply choper | Edson SP | |
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 | UE32C5700QSXZG | TV only turns on after several attempts and insisting on the control button | Power supply ok. ic203(z1031ai) with excessive heating | Cardozo | |
SAMSUNG | UE46ES8000 | Frozen images appear, with mixed colors, the TV turns off, it appears to be the LCD panel | Oxidized power connectors | Cardozo | |
SAMSUNG | UN50NU7100G | Backlight keeps turning on and off, no image | I isolated some tracks from the lower lvds cable on the main board. got the perfect image. good luck to everyone! | Eletrônica Cecé. Brumadinho MG | |

SAMSUNG | UN50RU7100 | LED current reduction | Alter resistor r9101 for 4.7r | reginaldo moronte,eletronica junior caldas novas | |
SAMSUNG | UE55KU6100 | Does not work, does not turn on standby LED | Voltage of 13v with +/- 9v. Defective solders on capacitors c245, c247, c248 and c280 | Re-weld the affected lines | |
SAMSUNG | UE55H6200AW | Turns on, backlight comes on but tsound is no image. | Fault in the LCD panel, tsound is a short or leak in the panel capacitors. | Check all capacitors connected to the power supply line, especially the 22µf capacitor at the end of the line | ERP-ASSIST |
SAMSUNG | UE32J5200 | Image with poor colors without the possibility of adjustment | R5_gain in incorrect service menu with no possibility of correction | Rewrite memory 24c256 | ERP-ASSIST |
SAMSUNG | LT24B301EW | Stand-by light flashing, does not start | At power supply, 1200µf/10v capacitor disabled | ERP-ASSIST | |
SAMSUNG | LE22C450E1 | Doesn't start. led blinking | Capacitor shorted to the rf input | Pablo | |
