SAMSUNG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | UN40C5000 | With sound without image | Tcom | ||
| SAMSUNG | P2470HN | Random backlight turning off | This brand of TV is a bit problematic with backlight. erased it randomly. | I replaced all the electrolytics even though they were working. I redid the soldering of the transformer responsible for the backlight (tm-08190) and the TV started working again. | Isaac Dias - RJ |
| SAMSUNG | T28D310LH | Standby LED on, but does not accept power | Check if tsound is a voltage of 5v on pins 11 and 12, if not, change the qm854 on the power supply, it releases 5v to pins 11, 12 of the power supply | Replace qm854 | MIGUELTV |
| SAMSUNG | LN26B450C4M | Turns on but no images only with sound | Qb801 e d1832 | 3R | |
| SAMSUNG | UN32F4200AG | The screen turns off spontaneously and the bus is ok. | Poor contact. | Reinforce the contacts of the cable that connects the power supply board to the LED board inside the screen. | Persio (TVCompany) |
| SAMSUNG | UN46ES6500G | It doesn't turn on, the red LED just blinks | Shorted sems27 processor, shorting the coil and transistor close to the processor. | I replaced the processor and the board worked perfectly again. The reballing didn't help because the processor was shorted. | Darci Denzer |
| SAMSUNG | UN32J4000AG | It only stays in stand bay, press the power button and the red LED flashes | Transistor q244 with one side open processor without 1.2v or 1.5v | Replace transistor q244 | Portal tec eletronica junior cat |
| SAMSUNG | LT27A550 | This TV was turning off and sometimes restarting. | Poor contact on the two pins of the cable connector that takes the 5v to the signal board. | Remove the connector and see if the two pins that take the 5 V to the signal board are not singed due to poor contact. If so, make a jump on the outside with a piece of wire, connecting the 5v directly from the power supply board to the signal board. | Waldemar Olbertz |
| SAMSUNG | CL21K40MQ- | Turning off, it works, after a few minutes it turns off and the speaker makes noise, | Replace diodo zd805, 9v1 e zd 807 ,5v6 | DJ PITUKA | |
| SAMSUNG | LN32R71BXIXAZ | TV turns on, lights up and then turns off, TV works normally | T106 transformer inverts giving high or open resistance | Replace of traffic | ANTONIO C GASPAR |
| SAMSUNG | UE46F6670SB BN44-00623B | The logo appears, the relay arms and switches off then, if disconnected from the network, the backlight flashes | Check and replace icm901 and ic1902 (slc2013m) | Mário Martins | |
| SAMSUNG | CL21K40MQ | It doesn't turn on, tsound's just a tick, noise | Change toasted cap cr409 471.2kv this one | DJ PITUKA | |
| SAMSUNG | CL21K40MQ | Vertical closed, both at the bottom and at the top, the screen is reduced, image in the middle of the screen | Change resistor r219, 390k, precision resistor, next to the processor. on pin 21 of the processor. | DJ PITUKA | |
| SAMSUNG | 740N | Turns on, blue LED on, no image (black screen) | 3 defective capacitors c301 25v 820uf and fusistor f301 125v 3a LF (green) | Replace of the 3 mentioned capacitors and fusistor. Be careful, don't forget to replace the fusistor as its function on the board is to protect all spike lines. If it opened it is because the peak exceeded its thermal dissipation capacity, without it the board would have been damaged beyond repair. do not bypass by excluding the fuser from the diagram. | Igor Cruz Brilhantino |
| SAMSUNG | UN32EH4000G | Screen shaking and double image | Take r25 r37 r39 | GELSON | |
| SAMSUNG | 2232BW PLUS | Turns on and off quickly | Broken wire in lamp solder and sparking | Resoldering and local insulation | Jjsantosneto |
| SAMSUNG | UN48JU6000 | Turning off by itself, does not turn on or turns on and off | Cold welding at the power supply | Resolder the entire power supply mainly to the tm-801cs transformer | Alex Lopes <small>This email address is being protected from spambots.

| SAMSUNG | PL43F4000AG | Doesn't start | On the power supply board the blue cs809s capacitor had poor contact, it was loose | Resolder the cs809s capacitor! zero cost tv returned 100% of the budget made before 350 reais! suggestion, before spending this amount try to solve it like I did, I didn't spend 10 minutes | Anderson |
| SAMSUNG | UN40J5200AG | To reduce the voltage of the LEDs and consequently the current, replace the resistors r9163 and 9164 with just a 1ohm resistor (1r) | The LED bars were burning out. This TV is not that old and the LED bars are not easy to find. | I tested it with a 0.22 resistor, the current drops a lot, with 0.75 it also works, I put it at 1r, it was fine, good luck everyone. | Eronaldo (erontec) |
| SAMSUNG | PL51F4000 | LED does not turn on, blinking 3 times | Ic801 com 4,7v no pino 8 | Transistor connected to c802 with leakage (it is close to the power supply connector) | Portal tec letronica junior cat |
