Samsung Repair Guide: Common Issues and Fixes
Brand | Model | Fault | Detailed Problem | Solution | By |
---|---|---|---|---|---|
SAMSUNG | LN40C530F1M | Stand-by LED is on, when you press power nothing happens. normal voltages of 13v b and 5v a and b. However, voltages b turn on and off while a remains stable | Ci hdmi (ic 1101) shorted or with faults preventing the TV from starting and triggering main board protection | Remove the CI and test the board again on the TV, if it works, replace the CI with a new one | Eletronica SV - Guaira PR |
SAMSUNG | UN48J6300 | The backlight does not come on, nor does it blink after replacing the complete LED panel, in addition to a defect in the LEDs, also in the power supply, probably the panel and LEDs caused an overload due to a short in one of the LEDs and the power supply failed. | I.c position ic9101 (7014x / 1449) smd in the secondary of the power supply, it switches the 02 fets that feed the LEDs and also the position transistor qm885 | I replaced it because I had scrap, but I don't know the correct nomenclature, without time to open a schematic. interesting in this project, because although the power supplies come out separately from the connector that goes to the LEDs, in fact in the power supply itself if you observe the rulers go in series from to to apr, tsound are 03 pairs of rulers... that is, 02 + 02 + 02 in series. | MIGUELTV |
SAMSUNG | UN32EH4000 BN44-00492A | Nothing turns on, not even the standby LED | After analysis, the open fuse was identified in position fp801s, transistor mdf10n60 position qm802s and ci sk2n3 smd in position icm801s | Replace them and the TV will be back to 100% | Luiz Sena Eletrónica HYK |
SAMSUNG | UN55RU7100 | Main electrical discharge | Has different versions. transferring components from one to another using the old board reference (if you have the other version on hand*) | Adaptation: place or remove regulator q410 and adjacent ones (cap and smd resistors around it), replace the ic1603_ut memory and remove and add some resistors close to the 2 lvds connections (with a lot of patience, compare and replace little by little so as not to get lost). works perfectly. If you don't replace the image memory, it will be turned to purple. God bless us! bysc | |
SAMSUNG | UN32FH4003G | Bn44-00492a = bn44-00554b, with identical voltages and identical connection, identical LED current voltage. | MIGUELTV | ||
SAMSUNG | LN26B350F1 | After a while, the PFC backlight +b turns off ok at around 388v, drive-on pin ok at around 4.7v | Possible weakening of the lamps, the PCI was also damaged, the two 47/50v caps were replaced in series and that didn't solve it either. | In the ci drive of the BD9893f lamps connected pin 10 to ground through an 82k resistor disabling the protection | You tube - Direto no defeito |
SAMSUNG | HW-E450 SOUNDBAR | Subwoofer box did not turn on stand by turned off | Subwoofer primary power supply defect | Replace do c.i. (1s1c01) - ice3br4765j | PAULO PINHO |
SAMSUNG | LN32C350D1MXZD BN91-06144J | Turning on and off normally, but without image/audio/backlight | Failure in ic203 (aoz1031ai) measured value was 1.13v instead of 3.3v | Replace ic203 (aoz1041ai) | leitemarcellus |
SAMSUNG | T27B350LB ... | It doesn't turn on, it just works on standby | Dm852 diode shorted at power supply | Dm852 diode shorted at power supply | Luiz Gabriel |
SAMSUNG | QN55Q70AAG NAO SEI | Dead | I changed the coupler photo I changed the oscillator, the same thing happened, the defect was in the diode in the dn 811 power supply, short | ELETRONICA DJ | |
SAMSUNG | UN50HU7000G TV | Does not turn on, with standby access. A blue LED is lit on the main board. all tensions present. | An smd c408 capacitor close to the audio output coils. | Replace or leave without...you choose. | JC Eletrônica Cícero |
SAMSUNG | UN48JU6000 | STBY LED flashes 5 times, no image, backlight working | Resistor on the v-com board in position r06 in the right corner of the screen and fuse on the t-com f800 | FABIO | |
SAMSUNG | UN40EH5000 | Mau contato no backlight | Ver r9119 | GIOVANO ELETRONICA | |
SAMSUNG | T220M | Lamps turning off after a few minutes on | Entering protection | Remove jamper j308 // felipe t repair electros! | TAVARES |
SAMSUNG | LN32C450 | Only turn on stand by | Shorted capacitor cp814 220nf by 2k | HP ELETRONICA | |
SAMSUNG | LN19R81 | Inverter protection | Wear of the LCD lamps. | Transistor q1 is responsible for the protection circuit when the lack of phase in reverse (shorted lamp or inoperative output) or one of the phases is uneven (lamp wear) and a potential direction is generated and q1 is activated, well I put a resistor 10k from the collector of this transistor to ground and the protection circuit stopped activating, when the collector raised the voltage above 1.0vdc the protection was activated, with this resistor the collector remained stable at 0.2vdc, hence the protection circuit was deceived | Edson Caeté |
SAMSUNG | 51F4000 | Turns on very weak and grainy image | Fet 9n25 on the y-sus almost at the tip of the board, tsound are two but only one was bad. I replaced it with the smk0460 and it was fine. | Sylvox | |
SAMSUNG | HTX625 | Protection | Energy | Rafhael | |
SAMSUNG | PL60F5000 | Pulsing power supply, turning off | I desoldered and resoldered capacitors and resistors around the ICP801 IC, I resoldered RP808 resistors and nearby resistors, I resoldered RP839 and nearby resistors, it seems that the glue under the resistors changes the resistance. | Marcelo | |
