SAMSUNG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | PL43F4900 | Sometimes it doesn't turn on, it doesn't even light up on stand by, sometimes it turns on | Do a test with a thermal blower or a head heater on the main board, if it gets hot and turns off, replace the capacitors c1024 and c1025 with 10uf/25volt electrolytic capacitors, note: observe the polarity, just find the negative side with a multimeter on the device's chassis | reginaldo moronte,eletronica junior caldas novas | |
| SAMSUNG | DA-E750 | The sound comes out very bassy and even with the volume at maximum, it is low. | Replace ic701 - ic7002 (s4560 amplifiers) and check/replace all capacitors in the amp circuit. | Neu | |
| SAMSUNG | LN32C450E1M | Does not turn on, the standby LED lights up (time on, time off) | Check cold solder on the rm811 smd resistor located at the power supply, just resolder it and run for hug. | Eletronica Oliveira | |
| SAMSUNG | LC46C530F1M | Doesn't start | TV does not come out of standby, replace the ic203 in the main one, aoz1031. aoz1035 is compatible. good luck | AXCELL ASSIST TEC | |
| SAMSUNG | LT27A550 | Does not turn on LED turns on and off, no manual control is left, accepts command via control but nothing happens. | Ic 204 | Input voltage ok, no output voltage just replace ic204 z1033a easy to find in scrap. | Assistec lg |
| SAMSUNG | UN65NU7100 | TV heats up and only the sound disappears | Speaker with the coil scraping and activates the sound amplifier protection. defect caused by using sound at maximum volume. | Replace speakers | SANTOMEL |
| SAMSUNG | UN32EH5000G | Stand by LED flashes 5 times but does not turn on | Cold solder on the processor | 2 minutes with station 850 did the trick. lol... _good luck! | Jhone eletronica |
| SAMSUNG | UN32EH4000G | Power supplys ok but not on standby led off | Ci 202 shorted or leaking | Replaced sleep.... good luck! | Jhone eletronica |
| SAMSUNG | UN50TU8000G | LED bus does not light | LED control sector photocoupler, change without testing | HAHNRAHN | |
| SAMSUNG | T27A550 | Turning on and off alone, changing channels and other functions alone, intermittent defect | Touch keyboard replacement (control sensor plate) | reginaldo moronte,eletronica junior caldas novas | |
| SAMSUNG | UN40D5000 BN44-00458A | Blinking LED does not turn on | LED bars burned out and q9101 shorted, zeroing 114v supply | REPLACE COMPONENTS | NILTEC |
| SAMSUNG | LN32B350F1 | It turns on, has sound, rear light and video, after a while the rear light turns off and continues with sound. | Defect in the inverter circuit. which is together with the power supply board | Place a 2k2 resistor between pin 14e16 of the ui801 smd ci (without 2006). 14-vcc-supply voltage pin 16-en-enable pin. | Ademir tc |
| SAMSUNG | UN49MU6100G | It would turn on and within a few minutes the backlight would turn off with a dark image. | Thinking it was the bus, I opened the TV and tsound was an LED open. I replaced it for new ones, and when I called it, it had the same defect. So I went to see the power supply, it was ok. | I replaced the mains and it didn't turn off. it was perfect. | JC Eletrônica Cícero |
| SAMSUNG | MX-JS9000 | Increasing volume goes into protection. "fan 2" appears on the display | Transistor fa07 open close to fan 2 connector | Replace it with another digital transistor if you don't find the same one | Stiltec |
| SAMSUNG | T27B350LB | TV doesn't turn on, just blinks on standby. voltage ( ps_on ) missing. | Check q202 is r206 on main board. in my case it was r202. replace with a 10k one | Júlio/ Eletrônica JM | |
| SAMSUNG | UN40EH6030 | Stuck in standby | Transistor qq852 is broken, it is an n-channel MOSFET | Remove the wire from the connector corresponding to the p-on, the TV will turn on normally, then just replace the transisot qq852 on the power supply next to the connector, it is smd and is connected to the photo coupler | Ariel Santos |
| SAMSUNG | UN55F6400 | LEDs on the bottom do not turn on | C9015 short open resistor r9015 | CLEBER LIMA RS | |
| SAMSUNG | PL43F4000AG | No image | TV came from another service, they had already replaced c5078, q5000, d5057, and q5014 but tsound was no image, checking the circuit I found an omic value of 30r between the base terminal and emitter, changing the ci u5022 returned the value of 10k and the TV gave an image. | IRIS TECCENTER | |
| SAMSUNG | LN19A330J1 | White screen with no image | Fuse f1 on the vcom board | Replace and run for the hug | RYK |
| SAMSUNG | UN40D6900 | When turned on, smart appears and restarts | Loose or open led | Cabeça |
