| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | UN40J5200 | Turns on with flickering backlight and no image, no plot, no audio and no remote control or keyboard | With the power supply disconnected from the main board, the LEDs light up normally. dc dc converter 3.3v on the main board smd capacitor position c2010 | MIGUELTV | |
| SAMSUNG | PL50C7000 | Turning off by itself | Cold solder on the power supply board. | Check and redo all cold welds at the power supply. | Arnoltec |
| SAMSUNG | UN50RU7100 | TV stopped, main board bad | The replace of the same | Normal power supply, but the main board is bad. note; pay attention to the code on the label that is on the board, it has the same code, if you put another one with a different code the same will work, but without an image, in my case the code was bn94-14756a | Alex Lopes <small>This email address is being protected from spambots.

| SAMSUNG | UN46F6100AG | Does not light LEDs, | T con board, releasing the flat cable that connects the main board and t con, the LEDs light up | T plate replace with | Gabriel GXP |
| SAMSUNG | UN55KU6000G | It doesn't turn on or the standby LED lights up | Faulty capacitance in the secondary power supply on the 13v line. when disconnected from the motherboard the LED bars lit up normally, when plugged into the motherboard the voltages disappeared remaining only 8.8v wsound it had to be 13v making it impossible to function | Replace the 4 25v capacitors with 470μF in positions cm858, cm857, cm856 and cm855. then it will work normally again | Francisco Melo eletrônica M.F |
| SAMSUNG | LE40B620R3W | Doesn't start. power supply inoperative | Shorted fuse due to MOSFET n 600v/5a | I put a channel n 600v/9a and it worked well | C. Santos |
| SAMSUNG | UE55JU6500K | Very clear image in the middle of the display, reminiscent of problems with the deflectors of old crts | After testing the t-con and main, it was found that the problem is actually on the panel | Replace the panel | C. Santos |
| SAMSUNG | UE40C5100 | Doesn't start. dead power supply | Short in the power supply. 2A fuse open. short on ic ice3br1765j | Replace ci for 3br4765jz and replace the fuse | C. Santos |
| SAMSUNG | 40F6400 42 POWER SUPPLY | Does not turn on, stand-by led blinking blinking - no power-up | Rs802 the 10r | Coloquei 2x 22r smd (one over other to more temperature dissipation) | Mauricio FOCONET |
| SAMSUNG | LN32D400E1 | TV doesn't turn on, no STBY, power supply ok | Defective main board. | Defective ic1204 reg smd stby did not have 5v at its output (js31z) replace to resolve. | RNSPTEC |
| SAMSUNG | UE40KU6100K | Doesn't start. power supply inoperative. | Mosfet n shorted, 5a fuse open | Replace mosfets 50r380 e fus. 5a | |
| SAMSUNG | UN32EH5000 | Does not turn on or stand by | CM852 capacitor blown underneath(47ufx200v), taking with it ic202(3v3 regulator) and ic 201(submicon) | HP ELETRONICA | |
| SAMSUNG | UE32D5500 | It's always restarting | Ic1302 memory failure | C. Santos | |
| SAMSUNG | UE60JU6800KXXC | Does not turn on, power supply inoperative | Short in power supply | MOSFET N 18A/500V shorted (MDF18N50B). I replaced it with MOSFET n 21a/600v | C. Santos |
| SAMSUNG | 37LD450 | TV turns on and then turns off or works for a while and turns off | Failure of one of the lamps with poor contact | Cleaning and checking connection contacts | Mário Santos |
| SAMSUNG | UE40H5003 | Turns on with black screen and sound. | Panel board with shorted 12v line. cd34 failure | Replace with 10µf/10v capacitor connect negative to chassis | Duartes |
| SAMSUNG | UE32F5000 | Black screen, backlight on and sound ok | Problema na t-con | Check/replace ic200(isl986021) which is shorted or replace t-con | Marco Marques |
| SAMSUNG | EU22ES5000W | Turns off after turning on | It appears to be excess consumption but it is just a faulty solder on the power supply control circuit. | Matias | |
| SAMSUNG | UE32EH4003 | Nothing lights up | Dead power supply | Failure in diode dmb07c (sb5150) at the power supply | Alex |
| SAMSUNG | UN40J5200AG | LEDs do not light up. | Open leds. open fuses. bars coming into contact with the chassis. | Replace LEDs and fuses. isolate chassis bars. reduce inverter voltage (traditional 3~5w resistors r9163 and r9164 of 2.3Ω in parallel. the higher the resistance of the set, the lower the voltage. | Erick |
