Samsung Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| 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 |
| SAMSUNG | LN32B350F1 | Turns on without backlight, PFC 380v ok, after changing the caps. secondary did not turn on | Capacitor with bad insulation, ok capacitance 474nf, but faulty voltage (c1832) supply 1st transformer | Moraes | |
| SAMSUNG | PL-50P5H | No image | Check 4 diodes na y-sus zd5016, zd5017, zd5023, zd5024 | ibramo | |
| SAMSUNG | SCM5550 | No sound at output | Rd6 e rd1 | Matias ERP | |
| SAMSUNG | CL 29Z43 MQ | Does not turn on or st by lights up | Primary power supply zener diode dz 813 shorted. | Primary power supply zener diode dz 813 shorted | JR tec |
| SAMSUNG | UN40F5500AG | Does not accept functions/commands only from the remote control, the TV keyboard works normally | When taking voltage measurements on the control board, the IR pin had a voltage oscillating from 1.4v to 1.8v. | Defect in ic1201, after taking all measurements of IR line components. The only thing left was the ic1201 as a defect, after changing the ic, the IR voltage stabilized at 3v3 and started accepting commands via the remote control again. | EC |
| SAMSUNG | UN40F5500AG | Does not accept functions/commands only from the remote control, the TV keyboard works normally | When taking voltage measurements on the control board, the IR pin had a voltage oscillating from 1.4v to 1.8v. | EC | |
| SAMSUNG | UN32J4000AG | Sem backlight, as normal | At first we thought it was a burnt out backlight, but in the end it was working 100%, the defect was caused by a smd 334 (330k) resistor that is positioned right next to the backlight power plug, it is between the cn1401 plug and the fet q1401. the resistor in question was damaged, just change it. | Check the resistor in question and replace it if its characteristics have replaced. | EC |
| SAMSUNG | UN48H4203AG | Connect everything else without image | Defect was cd10 on the vcon changed it was just removed | <small>This email address is being protected from spambots. You need JavaScript enabled to view it.</small> | |
| SAMSUNG | CL21A551ML | White image with retraction line and cushion effect | 200v track starting between d407 and j252 | MEO-ELETRÔNICO Cajupiranga (RN) | |
| SAMSUNG | LT22A550 T22A550 | It works but the back light doesn't come on. replacement of the ICD801, DD850, QD850 on the power supply PCI. | Icd801-oz9998bng , dd850-sr210 , qd850 10l01 (mosfet). | It worked perfectly after replacing the components described. I used the 15l01 instead of the 10l01 and it worked very well. This TV monitor is using the bn44-00448b or bn98-03094b board. | Ferrarini |
| SAMSUNG | LN32A450C1 | Loses image after a few seconds leaving only the sound | Lamps turn off after a while due to protection being armed | Put a 10k resistor from pin 15 to the ground of the oz9966sn on the inverter board! | Lucas |
| SAMSUNG | PL51F4000 | Dead sign board | Diodo zener do +b 3,3v em curto | Replace zener d901 prox power supply connector | edmilsompimentel |
| SAMSUNG | PL51F4000 | Sometimes it called, sometimes it took a long time to call | 3v3 that feeds the eprom with 4v5v, right, it would be 3.3v | Replace the regulator IC on the IC806 signal PCI. | edmilsompimentel |
| SAMSUNG | 32D5500 | 12 volts pulsating | Fet qm855, put a 120k resistor from gate to ground | Rafael's tip | HP ELETRONICA |
| SAMSUNG | 32D4000 | 12 volts pulsating | Cm855 fet, place a 120k resistor from gate to ground | HP ELETRONICA |
