Samsung Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | PL51F4000AG BN44-00599A P51HF | Normal power on does not generate video, slight blinking | Defect on the power supply board, mosfet transistor qx854 partially shorted | Test before ysus plate, plate | Eletrônica Sorriso Maike |
| SAMSUNG | LN40B530P2M | Does not turn on (normal power supply) | C207 short (it is next to the ic8005 memory) | Capacitor elimination | duc40rj |
| SAMSUNG | UN65HU8500GXZD | Doesn't start. Defective standby power supply. defect caused by the plastic underneath the PCI which rots and releases conductive oil and which also corrodes the board | Replacement of the IC pwm of the standby power supply s3330 position ics801 and the 1Ω resistor position rs801. Clean the board thoroughly and check for possible corrosion spots that could cause other defects on the board. | rafaelmoraes99 | |
| 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 |
