SAMSUNG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | PL42C450B1MXZD | Relay does not set voltage vs 220 | Controller board does not release vs-on and ps-on | Replace the controller | ON-PLAY ELETRONICA |
| SAMSUNG | UN40D5000PG | Do not connect a 5 volt power supply or without the 13 volts and voltage of the LEDs! | Causes icm803 eb6 (tl431) changed, it raises the voltage at the base of the qm801, which cuts the 15volts of the pwm circuit from the 13volt power supply and inverts! | Eletrônica Yamada | |
| SAMSUNG | UN48J5200AG | Turning on normally, but no image (common fault for this TV model) | Tripping the LCD display supply voltages (led2 avdd off) | Isolate pin 18 of CN1 on the T-Con or RK27 board (33Ω) to release voltages and isolate the pin | leitemarcellus |
| SAMSUNG | CL21C650ML | It doesn't turn on, the LED turns on, press power, the LED pays more and doesn't turn on, the power supply goes up | Change electrolytic capacitor c846 100x25v next to the relay at the power supply. | Dj pituka | |
| SAMSUNG | CL21C650ML | It doesn't turn on, a defect in the power supply, the LED turns on, I press the button, the LED goes off but it doesn't turn on, the bitudo cap stays charged and the power supply goes up, | Replace diodo zener zd807 , 5v6 , zd 808,4v3 e zd842 4v3 | DJ PITUKA | |
| SAMSUNG | CL21C650ML | Arming protection and sometimes turns on | Solda fria na memory | Solve | EMANUEL |
| SAMSUNG | UN46EH5000 | The LEDs turn on without the main PCI, despite having all voltages stable, lighting up the bus, the moment it connects to the main PCI, it kills everything. | Change secondary power supply capacitors, 470/35v, 1200/25v | SIM TV | |
| SAMSUNG | UN40D5500 | Piscando std by | 100/63v power supply capacitor | SIM TV | |
| SAMSUNG | PL43F4000 NA | Dark image with reddish pigmentation | Power supply board, voltage is 17.89vdc instead of 58vdc. | Open resistor in the feedback network, ra875 of 3.3kΩ (smd), is in line with the VA adjustment trimpot | Robusto53 |
| SAMSUNG | PL43F4000 NA | Dark image with reddish pigmentation | Power supply board, voltage va with 17.89vdc instead of 58vdc. short in diode d352 (sb3200), it is close to the 3 photo-couplers. | Robusto53 | |
| SAMSUNG | 50NU7100 50RU7100 49RU7100 | Image only in the middle of the screen. like a strip of light in the middle of the screen with a normal image and the sides, everything is dark! | Burnt out LED bars and high current in the LED power supply. | After changing the LED bars, replace the r9201 and 9101 resistors with 4r7 x 2w resistors and sand the light-diffusing acrylic. | Samuel Silva |
| SAMSUNG | PN51H4500 | It turns on whenever it wants, I noticed that on hot days it turned on easier | Qq807 and qq806 at power supply | Replacing std5915 transistors | FelixClank |
| SAMSUNG | PN43H4000AG | Tsound is no VA and VS voltage | Icm851 (tl 431 -smd) | Icm851 | Tibúrcio |
| SAMSUNG | UN40J5200 AG | Burning led bus solution | Lower the LED current by removing the two low-value resistors of 2.3 homs and placing a 3.6 homs connected to the fet socket that powers the LED bars | And good luck | <small>This email address is being protected from spambots.

| SAMSUNG | UN32D5000 | Whitish image | Defective tcon | Replace capacitors smd disc c625626627 one of them has a leak. I don't know the value, I took it from another tcon | oskarala |
| SAMSUNG | 32JH4205G | LED blinking and won't turn on. Sometimes it turns on the backlight, the Samsung logo appears and then it turns off and the LED flashes again. | Q211, 3.3v switch, power supply connector side on main. 3v goes in and 3v comes out. | Switch or jumper | joaomvjr |
| SAMSUNG | PL42B450 | Voltage vs low | Cs811 and cs847 capacitors swap which solves | Marcio Gomes | |
| SAMSUNG | HT-C550/553 | Doesn't start | Line connecting pin 4 of the oc2 coupler interrupted | milenio | |
| SAMSUNG | LE32B450 BN44-00261B | Doesn't work. | Multiple components, replace: icp801s (fan7350), rp814, rp815(2 mω), rp816, rp817(1.5 mω), rp819(56 kω) | Rui | |
| SAMSUNG | LN40B530P2M H40F1-9SS | TV turns on but tsound is no inverter voltage for lamps | Changed the PC802S photo coupler and the ATV turned on normally. | eletronica vf |
