SAMSUNG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | LN32A450 | Time it turns on, time it doesn't turn on | C1015 | HP ELETRONICA | |
| SAMSUNG | LN32D400 | Without 5v, without 12v | Position transistor qb801 on the power supply board. | TV CENTER GUAIBA | |
| SAMSUNG | UN40F5500AG | Restarting | Poor contact between the power supply board and the main board. 1.3 power supply pins oxidized. | Solder a wire directly from one board to another. | Pardal - X |
| SAMSUNG | UN65HU8700GXZD | No image and no functions on the screen (menu) | Tsound is no 13v voltage that powers the t-con, due to the shorted capacitor c174, it is in the audio amplifier circuit. | Moura1 | |
| SAMSUNG | UN40F5200AG | The backlight keeps flashing and doesn't turn on. | 5v stable, 13v oscillating between 8v ~10v. defect in a smd rs802/10r resistor (close to the ics801cs) its value was altered, it measured more than 100r, thus changing the voltage from 15v on one side to less than 7v on the other, just change it for a 10r and the defect resolved! | EC | |
| SAMSUNG | LN26R71B | Does not turn on red LED lights up and keeps oscillating | Problem power supply. 22uf/50v dry capacitor | The capacitor was replaced and the TV started working normally again. | Adriano Miranda |
| SAMSUNG | UN40J5200 | After a while it starts restarting | Transistor q210 ao4449 | Changing the transistor without measuring. | fernando |
| SAMSUNG | UN40C5000QM V400H1 | LED turns on, all voltages ok, has backlight, has audio, but no image | Tcon - 12v fp1 fuse open (I read in another topic that it would be 3a, I'm not sure), cause: capacitor cp47 (10uf ??v) shorted, I removed it and the 12v line went up. I took advantage and, prophylactically, I also replaced its twin cp46 (same specification and are in parallel) with a 22uf 25v electrolytic capacitor. apparently it is a common defect in this tcon, if you search you will find several qp2 transistors (power mosfet) charred because these capacitors short out and lead to the fet. I was lucky because my QP2 was good. good repairs! | 2000 | |
| SAMSUNG | UE55H6470 UE55H6500 BN44-00711 | Dead qm801cs qm802cs | Check/replace: fp801s (5a), nt811s(5d-13), qm801cs, qm802cs(std14nm50), rm814, rm816 (20ω), rm813, rm815(100ω), dm805, dm806(bav70), icm801(fa6a2in), cm813, cm816 (10µf/50v) | Collins | |
| SAMSUNG | UE55H6470 UE55H6500 BN44-00711 | Dead qp801cs qp802cs | Check/replace: fp801s (5a), nt811s(5d-13), qp801cs(60r380), qp811cs(60r380), rp802, rp812 (20ω), rp801, rp811(100ω), dp801, dp811(bav70), dp808c(fmn-1106), icp801 (fa1a50n) | Collins | |
| SAMSUNG | LN32FH4003G | The logo appears and turns off, the standby LED flashes | Capacitor 47uf/160v seco | Replace capacitor and the TV turned on perfectly | Eliomar Umbelino |
| SAMSUNG | UN40C5QMXZD | Does not turn on, no stand by light | (at power supply) oxidation on an icb801 track, dead power supply | I rebuilt the track and it started working again, remembering that normally the icb801 burns out..... so it's always a good idea to test | Saltech |
| SAMSUNG | UN32F5500AG | After a while it starts to restart | Cold soldering | I practically resoldered the entire power supply, and the TV stopped restarting. | FILIPE FURTADO |
| SAMSUNG | CL21C650ML | It doesn't turn on, normal power supply, the LED comes on, press power, it turns off and doesn't oscillate, the LED keeps blinking and every time it turns on, | Replace transistor horizontal q401 | DJ PITUKA | |
| SAMSUNG | UN40J5200AG | Flashing LEDs, no plot, no audio and no remote control. with the power supply loose, it lights up normally. | Dc/dc converter 3v3 short | Replace o capacitor c2012 | duc40rj |
| SAMSUNG | UN40J5200AG | Flashing LEDs, no plot, no audio and no remote control. with the power supply loose, it lights up normally. | Dc/dc converter 3v3 short | C | duc40rj |
| SAMSUNG | PL43E400U1G | Curto na ysus | I armed the va and v power supply and disarmed it immediately afterwards | Q5018 fgd4536smd q5016 não achei original coloquei rjp30h1 smd d5116 sf10a400 smd q5000 rjp63k2 e capacitor c5092 331 | This email address is being protected from spambots.

| SAMSUNG | MIX FS8000 | Rings through time and stops | I don't know | ? | Cleiton |
| SAMSUNG | PL43F4000AG | Stby lights up and doesn't work Sometimes it doesn't light up, when the power supply board heats up it works normally | Replace capacitors 807 808, 2k2 | ON-PLAY ELETRÔNICA | |
| SAMSUNG | CL-21Z58MQ ML21Z58 | TV would start, turn on, then turn off and turn on again | Cracked dd204 diode | Replaced resolved | FRANÇA-MACAIBA |
