SAMSUNG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | CL21K40MQ | First it turned on, after two minutes it turned off and didn't turn on again and it didn't even have standby | Cr 409 practically toasted | As I couldn't find the original one of 0.68nf/2kv I put one closer to the original capacitance which was 881k/2kv. it's working perfectly. | Celso |
| SAMSUNG | LS20CF | Turns off the screen in a few minutes | This problem on this TV is usually in the lamps, a solution without changing them would be to deactivate the protection by removing d1 and d2 on the power supply board | Miratec Eletrônica | |
| SAMSUNG | LS20CF | Turns off the screen in a few minutes | This problem on this TV is usually in the bulbs, a solution without changing them would be to deactivate the protection by removing | Miratec Eletrônica | |
| SAMSUNG | UN40C5000QM | No image | Main board q202 shorted or charred. | The q202 is a mosfet that feeds the t-com which damages due to something wrong with the t-com, check for shorts on the t-com, the q202 is a 6-pin mosfet, I couldn't find the TV schematic to put an original one with a lot of research I adapted another smd mosfet code: ao3407a with 3 pins that works perfectly before connecting the t-com turn on the TV without the t-com flat being connected and check if it releases the 12v line, if it releases the main board it's fine again, turn on the t-com after checking for shorts in the capacitors, I got 2 TVs with this same burning problem of the q202 and different places on the t-com one of the problems on the t-com after solving the short it still did not release the vgl and vgh which it was another smd mosfet broken with leakage, in the qp1 position it has a 3-pin mosfet and has the symbol of a ci drawn on the board, without a diagram again i used the same mosfet that i had already used in the q202 or ao3407a and then it released again the vgl and vgh voltages, only after that I turned on the display flats, making sure that all the voltages were restored, knowing that if something killed the voltages again it would only be the display itself, but both TVs and displays were good, and they worked perfectly again! I hope to help the group, as I have already been helped with other good tips published sound! | Play Back |
| SAMSUNG | T27A550 | It turns on and off by itself, sometimes it stays on for a while but then turns off again. | Ic1204 - three-terminal smd on main board. | Replace ic1204 by removing it from another samsung tv. or replace it with a 3-terminal smd diode - bas21. | I.G |
| SAMSUNG | HT-DS100S | Went into protection and turned off | Voltage regulator aic3-1, ka7912 shorted | Replacement | Aurelio Machado |
| SAMSUNG | CL 14B501K | LED on, when turning on the TV b+ goes up to 140v blinks 5x and does not oscillate q 401 | Tip from this channel a t402 primary terminal broken by zinabre | Is it possible to recover or replace | GDP2 |
| SAMSUNG | LN32B350F1 | TV sometimes turns on, sometimes it doesn't. insists on staying on standby. | Capacitor cm852 - 1200 microfarads, 10volts estufado | Replace the component with a new one | Hernandes G. Bandeira |
| SAMSUNG | CL21Z43MQ | Connects with audio without image | D 242 or 241 | novin | |
| SAMSUNG | UN32D5500 | Restarting itself after a while on | Nand flash memory - ic1302 (main board) | Swap nand flash memory. It is necessary to save the firmware in memory or buy it already saved. | I.G |
| SAMSUNG | CL21C551ML | Plate or cushion defect | R 411 82k gray red orange | AIRTON PARAIPABA CE | |
| SAMSUNG | UN46F5500 | Defect in standby 5v dropping when turned on. | Change ds804 diode, resistance changes. | Replace ds804 diode. | TV CENTER GUAIBA |
| SAMSUNG | UN55F6400AG | Turns off via the control and doesn't turn on afterwards ONLY turns on if you unplug it | Power supply defect | Transistor qq852 and resistor 10r smd 100 position rs802 | JORGE TVPARANA |
| SAMSUNG | RT59EBPN | Doesn't work | Relay ry71 is dead, you must change it. and it will work | Observ: main board code: da41-00222a | Kaya Elektronik09 |
| SAMSUNG LED | UN46C8000 UN55C8000 | Burnout of the stand by transformer -tb801s - resolved | To solve it, you have to adapt another one in its place, you will find it on the power supply board of a Samsung TV - bn44-00357a - problem solved. I advise using the power supply scheme. | After placing the chopper that they sell as original in ML and that is produced in China, only disappointment, the TV returned twice under warranty with the same defect. Even changing the ci, capacitor d 47x35v, doesn't solve it. The best way was to adapt a chopper from a plate I found in my stock. the chopper code is: efd2525,600μH pd46f1n-stb | Eletrônica ALLFATV |
| SAMSUNG | LN46C530F1MXZD BN91-XXXX | It turns on normally, if it turns off after a while it won't turn on again (it won't start) | Defective main board | I replaced the main board and it solved the problem, compatible models lnxxc530f1m | Maike SR |
| SAMSUNG | P2270HN LS22EMS | It turns on but the lamps that illuminate the screen do not light up but tsound is sound, the panel works | Ci u201-lem2005 | Place 100k resistor from pin 1 of the ci u201-lem2005 to ground (ground) | LIPENDLICH |
| SAMSUNG | 2270HN | It turns on but the lamps that illuminate the screen do not light up but tsound is sound, the panel works | Place 100k resistor from pin 1 of the ci u201-lem2005 to ground (ground) | LIPENDLICH | |
| SAMSUNG | LN26B450C4M | It doesn't turn on, the LED lights up, keeps blinking and it takes a long time for it to work. This defect is misleading, because as we know, if we remove the cable that comes from the main board to the power supply and connect it to the power supply, the power supply, if it is good, allows the lamps to turn on, and this happened, so I suspected the main board, but the power supply persisted. I found the capa cm852 with low capacitance, 1200uf/10v, it was 600uf | Cm852 sold out. | Cm852 replace | MIGUELTV |
| SAMSUNG | UN32J4290 | Does not turn on, completely inoperative, external power supply with 19 volts normal. | In this case, heating was observed on the plate in the upper right corner. | Short in smd ceramic capacitor c17 next to the ic206 regulator, just replace it and the TV worked normally. | ToniTec |
