Samsung Repair Guide: Common Issues and Fixes
Brand | Model | Fault | Detailed Problem | Solution | By |
---|---|---|---|---|---|
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 |
SAMSUNG | UN32FH4205 | Only the standby LED is on, all voltages are normal, you can press the power button and nothing happens. | Sem 3v3 no transistor q301 | Replace ic301, it is close to the headphone connector. | Naldo Lima |
SAMSUNG | PL43D490A1G RODRIGO COFFERI | It only turns on if the main board heats up | In addition to re-soldering everything on the other boards, check 1.2v at the output of ic204, on coil 202, if not, remove q206 next to the ic, aly | Rodrigo cofferi | Rodrigo cofferi |
SAMSUNG | MAX G55 | No cd/usb output | Opc capacitors 1, 3, 10, 13 - 10mf 16v from mpeg board | ||
SAMSUNG | MX-C730 | Doesn't start | Very oxidized power supply board, completely rusted jamp broken, cutting current. | Remove oxidized components and replace them. | JL-Eletronica (Jorge) |
SAMSUNG | UN32J4000AG | Lower current from LED bars | Connect an 18k resistor from pin 35 vref of the bd9397 ci to ground. It also works for Sony TVs that use this ci | Sérgio | |
SAMSUNG | UN32J4290 | The sound doesn't work | Burnt audio controller ic (ic301) | I checked the signals on the oscilloscope and tsound was no modulation on the 4 outputs, the input signals were ok, after the replacement it worked perfectly. | CDS_DIAS /LEDTECH |
SAMSUNG | UN32F4200AG | Image with excessive brightness | V-con board damaged by cockroach piss near dc circuit | Tip given by Andre, thank you brother. | MILENIO ELETRONICA |
SAMSUNG | UN40EH5000G | Standby LED blinks indicating that the TV has turned on, but the LEDs do not light up, all voltages are normal. | Metal connectors on the LED bars are loose, just tighten them and the LEDs will light up again. | DV Elêtronica | |
SAMSUNG | PL43F4000AG | Turning off after a while | Ts801cs and cs809s with cold soldering | Resoldering of ts801cs and cs809s | KAIO GARCIA |
SAMSUNG | UN50RU7100 | Does not turn on, LED is off. | Line 3.2 with zero volts. Cause: shorted smd capacitor c1409 below the processor heatsink. | It is used to shorting other capacitors on the same line. | ELETRONICA DANIEL |
SAMSUNG | UN32J4000AG AG | No video | Absence of voff voltage, 7v9 zenner with leak | D14 diode replacement | diego boeira |
SAMSUNG | 50RU7100 | No screen image | Shorted capacitor on vcon | Remove the capacitor that you find has a short in the VCON and replace the fuse on the main output board with Q221 | Lcjeletronico |
SAMSUNG | UN50F5500AG BH05 | Burning led bus | LED voltage too high | Replace the value of resistors r9163,r9263 (3r) to (4r7). | evando viana |
SAMSUNG | CL-21Z43MQ | Cup effect | R411 de 82k | Replace r411 of 81k cap100/25v which already had low capacitance | Rogério TV |
SAMSUNG | UN43RU7100 | No image and restart | Fuse y open (close to the connector that comes from the power supply) and c64 shorted on the vcon | Replace the two. | Maurilio |
SAMSUNG | BE49N | TV turns on normally for a few seconds image keeps changing colors red, blue, green etc! | Cleaning flat cables, or changing them! If you don't decide to change tcon with flet cables! if it does not receive a ground fault on the main board | Eletrônica Manauara | |
SAMSUNG | UN50NU7400 | Blurred image | Unidentified | ||
SAMSUNG | UN40J5200AG | No image, LEDs on. Note, first of all the LEDs didn't light up. | Fuse on the v-con board open and the 10uf ceramic capacitor CP6 leaking. Note, the capacitor is close to the up1 ci on the v-con board. | After changing the capacitor and fuse, the TV was ok. correcting the model (un43j5200ag) mentioned in another tip sent. | George Pontes |
