Samsung Repair Guide: Common Issues and Fixes
Brand | Model | Fault | Detailed Problem | Solution | By |
---|---|---|---|---|---|
SAMSUNG | MX-FS8000 | Turns on right after starting, give protect and turns off | Lack of power supply to the amplifier, high power supply does not activate | Jumper resistor j879 open and capacitor cm811 with little capacitance, with the replacement of these components the power supply returned to generating 52v and thus the device worked normally | charlotniu |
SAMSUNG | PL42A450P1 | It only turns on the stand-by but does not turn on - the ps on pin keeps pulsing. | Rl8025 relay receives voltage but does not activate. | Rl8025 relay replacement | Gênios Eletronica SJ SC |
SAMSUNG | LN37B530P2R | The screen turns off after a while or turns on without image and sound. | Photo coupler pc803s, open or changed on the diode side (pins 1 and 2). | After changing the TV ok. | George Pontes |
TV SAMSUNG 48 TELA CURVA | UN48H8000G | No image dark screen no black light | 8uf smd capacitor on the v-com board in short, in my case it was from the right ladi on the v-com board on the display | And just replace it and it's fine. | Leomar Esteter |
SAMSUNG | HG40NC450 | Call whenever you want | Primary problem DM863C diode (replace without testing) insert 3 SB3200, secondary problem, bad contact connector of the LED bars CNL802 | HAHNRAHN | |
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 |
