Samsung Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | LN26D450G1G | The screen flashes and sometimes restarts | Lack of pfc actuation (400v), caused by the ps-on command being low | The defect is in the q202 transistor, npn transistor, just replace it with another one and go for a hug! | Lucas |
| SAMSUNG | PL43F4000 | Image progressively grainy in some parts | A sus repair kit was replaced and the q 5000 rjp63k2 was fake | Replacing the q5000 transistor with an original one, be careful guys, tsound are a lot of these fake ones out tsound | PAULO PINHO |
| SAMSUNG | UN50TU8000G | One more case: turning off and on, loop | In the small flat (with to with) left side (wsound the flat cable from the main board comes in) from left to right (as it is written) isolated 3 tracks only, TV working normally | Claudio Jorge Eckert Junior | |
| SAMSUNG | UN49J5200 | LEDs burn out frequently. | When changing the LED bars, which are made of aluminum, completely isolate them from the TV housing. | The solution is to isolate the aluminum LED bars from the TV chassis | Antônio |
| SAMSUNG | UN43J5200AG | No stand by and no image on the screen. | Open fuse on the main board, f2002, jumper it or replace it. | Good LED buses, after analyzing just one bus with the diode open, I made the jumper and the TV started working again, solving the two defects. cled tec cell electronics. | Eletrônica Cled Tec Cell |
| SAMSUNG | LN26B450C4M | On, it turns on standby and when it doesn't turn on, it flashes. | Clean the flat cable from the main board to the screen and also replace cm852. | The flat was yellow with dirt and the 1000/10v cm852 put 1000/25v | Eronaldo (erontec) |
| SAMSUNG | UN60ES6500G | It doesn't turn on, sometimes the relay goes off, sometimes not even that | Standby power supply pulsing, with a peak of less than 3v | Tl431 ics851 with replaced reference voltage. | Davi.sls |
| SAMSUNG | UN55HU7200 | No image, backlight on | T con board, capacitor shorts out and takes the 12v input fuse | Replace capacitor cd11 and fuse f1 125v 7a | GABSENS |
| SAMSUNG | UN50TU8000G | On and off without stopping | Shorted screen | It has 11 trails and isolates 7 trails on the small flat on the left side, in some it works perfectly, not for everyone. | NILSON TVs |
| SAMSUNG | LN26D450G1G | Turns on normally after a certain time, turns off and restarts | Pfc power supply low, pfc did not work, changing cp812 and cm813 on the pfc power supply board was ok but then it restarted. the main board in the ps line on the r206 was changing is 10k | JP ELETRO | |
| SAMSUNG | CL21Z50Q | Does not turn on, LED is on. | 5v1 or 5v6 zener diodes on the 5v line of the memory, and the remote control sensor, shorted out. | Replace 5v1 or 5v6 zener diodes close to the remote control sensor, and on the 5v memory line. | MARCONES DE ARARIPINA -PE |
| SAMSUNG | LE32B530 BN44-00261B | No backlight, no voltage bending. it has 330v instead of 380v | Resistance r815 changed (more or less 1m instead of 2m) in the mesh of pin 1 of the 7530 fan | Replace r815 | |
| SAMSUNG | PL43F4000AG | Black dots in the image as soon as it is activated and soon after when tsound is an image with some color changes | Position resistor r4063 shorted. It is located next to a diode, below the y-sus output connector. | Good luck! | Emanuel Aphiletron |
| SAMSUNG | UN40F5500AG | The LED flashes 5 times in batches of 2 flashes and repeats, the TV does not turn on | Defect in the power supply, photo coupler pc802s (817b) two shorted transistors very close to the photo, qq852 and qq856 (k7k) | I replaced the 3 pieces and went for the hug | R10 Informática E Eletrônica |
| SAMSUNG | LT24D310 | Dead (stand-by off) | Ic 201 com fulga | Replace ic 201 - not finding the original, other similar samsung boards have it in the same position | George Luís |
| SAMSUNG | UN32J4000AG | Stand-by access but the TV does not turn on | Q244 faulty (open or shorted) | Replace the transistor q244 - if you can't find the original, look for another similar Samsung TV board | George Luís |
| SAMSUNG | CL21Z43MQ4 | I'm sound | Dz602 (5v6) open and the ic601 can use la42032 or la42102 | samuel leite | |
| SAMSUNG | P2470HN PLACA FONTE BN94-03234A | TV turns on (button lights come on and has sound), but no image | Inverter transformer without power supply; I noticed that the ci ap4506geh was burning. fuse f301 was also blown. ATTENTION: you must remove the fuse from the board to measure its continuity! | Changing the ap4506geh and the f301 fuse (4a 125v) - if not available, adapt the common fuse by soldering two terminals. I lost a lot of time because the f301 on the board continued, but when I removed it I found that it was open. continuity regardless of the fuse occurs thanks to other components that connect to its track. | Cadu |
| SAMSUNG | LN26B450 | Does not turn on, STBY LED blinking. After changing the capacitors, the problem was not resolved. | Ver dm 802 e cm 804 | Replace of the aforementioned items | arock |
| SAMSUNG | CL 29K40MQ | LED off does not oscillate horizontally | Diodo zener 5v6 dz903 | Replace and went | jose airton |
