SAMSUNG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | UN40J5200 | It turns on but is only on standby, when you press the power button, the standby LED turns off and comes back on and the LEDs do not light up. | Q206, ao4801(8-pin dual p-channel fet, soic 8) on the main board, close to the connector that comes from the power supply, with one of the fets changed. | Replace of q206 - ao4801. | Monitor Informática Campina Grande PB |
| SAMSUNG | UN32D5000PG ( VERSãO KS24) BN91-06362U/BN41-01747A | Turns on but does not activate the LED backlight and does not turn off via remote control | I found IC204(aoz1033ai) not generating the output voltage and I observed pin 6 of the IC which was at low level. It was Q200 with marking code 1e. | Replace q200 | leitemarcellus |
| SAMSUNG | LN40C530 | Doesn't start | Z1031a regulator, I replaced it with the z1021ha, used on another board, the only difference is the switching frequency, the 1031 is 600khz, the 1021 is 500khz. | Davi.sls | |
| SAMSUNG | UN40H5103AG | Whitish image on the entire screen. | When I removed the flat that went to the plate on the right (looking from behind) the image remained normal on half of the screen. Defective capacitor CD07. I removed it and the problem went away. | Jamilton Jr. | |
| SAMSUNG | UN32FH4205G UN32FH4205 | Don't log in | No diode problem | Dede | |
| SAMSUNG | UN32FH4003 | Doesn't start | Oxidized and rusty jumper j812 without contact on the power supply board | Jumper redone the TV started working again, check the connection of all components or jumpers that are rusty and oxidized if you find the suspect replace or redo the contacts etc.. i.e. visual analysis | Shweize |
| SAMSUNG | PL50C450B1 | Blurred image and whitish screen, with time it becomes normal | Oscilloscope signal with lack of set down ramp | Replaced the smk 1360 transistor on the ysus q6000. | DANGRA ELETRÔNICA SÃO PAULO |
| SAMSUNG | PL51F4500AG | Dead tv. totally inoperative | Open fuse regulator ic and adjacent components burned. | Replaced the stq7011k regulator IC with a strw6053s plus a disk capacitor and a 0.32Ω resistor, the power supply turned on, but with oscillating voltages and without turning on the TV. Found a shorted 18v zener on the photo coupler line plus an SMD resistor connecting the zener to the regulator IC. I replaced the resistor with a bridge and the TV worked normally. | Paulão Tchwrma |
| SAMSUNG | UN46F6100AG | Display freezing at the top on the right side of the screen, the display cof was found toasted | As I don't have a machine to change the CPF, it was resolved by removing it, it stopped paralyzing the image so it had the perfect color without details, remove the 3 side cofs on the right side of the display | Juliosantos | |
| SAMSUNG | UN46D6900 | Hits the relay and restarts and repeats over and over again | Altered led buses | Replace LED buses. resolved. | |
| SAMSUNG | T22B300EW BN44-00505A | Doesn't start at all | Swap: ICM801(strw6052s), cm804(221pf,1kv), dm801(uf4007)/fp801s(4a), bd8015 (bridge rectifier to 6a). | WebLogs | |
| SAMSUNG | T22B300 BN44-00505A | Touch panel lights up, no function, TV does not turn on | Power supply bn44-00505a, tracks near the chopper very thin, resistor rm801 burned, capacitor cm855 bloated | Replace rm855 for 2r5 1/2w under the board, replace cm855 for 1000µf 25v. thicken primary tracks with soldering / update software via usb or rewrite eepron | Jerolamo |
| SAMSUNG | UN32EH6030G | Duplicate image | In my case, I put some 3mm tape on the flat that goes on the display and it worked, it's a lot of work, I made several attempts | Marcelo | |
| SAMSUNG | UN75AU7700G | They swim on canvas | LED bar and short to the chassis | The above components were replaced; device ok, remove the 4 2r7 resistors and insert a 4r7/2w one, reducing the voltage from 115v to 100v | Valdecir Schena |
| SAMSUNG | UN48H4203AG | The TV turns on normally with the image, then it takes effect as if the defect were the display, the image fades and freezes as if it were actually the screen. | Defect was the driver of the vcon ci ck1 board (bm81224muv qfn) changed, defect resolved... | ALVES.TEC ELETRÔNICA.CAMARAGIBE/PE | |

| SAMSUNG | UN65F8000AGXZD | TV doesn't turn on, just the backlight keeps flashing with the relay beating. | Check two cis responsible for the backlight on the power supply PCI. see slc1013m and slc2013m. If the backlight flashes at the top and bottom, it means that the center LEDs are not lighting up and the possible defect is in the SLC1013m and if it only flashes in the center of the screen, and does not light up at the top and bottom, tsound is a possible defect in the SLC2013m. | Replace of cis slc1013m and/or slc2013m | rafaelmoraes99 |
| SAMSUNG | LN32D400E1G | Doesn't start | Ci202 smd noneclstura 90108 booster from 5v to 3.3v | Changing the ci202 I removed it from another samsung board | Eulercell |
| SAMSUNG | UN43RU7100 | Blowing fuse, rectifier bridge and MOSFET. | Ceramic capacitor next to the diode next to the qp801cs mosfet. Tsound is one on the diode and one on the MOSFET. | Changing ceramic capacitors. qp801cs rectifier bridge, and fuse. | Lucaseweb |
