SAMSUNG Repair Guide: Common Issues and Fixes
Brand | Model | Fault | Detailed Problem | Solution | By |
---|---|---|---|---|---|
SAMSUNG | LN32B350F1 | Turns on without backlight, PFC 380v ok, after changing the caps. secondary did not turn on | Capacitor with bad insulation, ok capacitance 474nf, but faulty voltage (c1832) supply 1st transformer | Moraes | |
SAMSUNG | PL-50P5H | No image | Check 4 diodes na y-sus zd5016, zd5017, zd5023, zd5024 | ibramo | |
SAMSUNG | SCM5550 | No sound at output | Rd6 e rd1 | Matias ERP | |
SAMSUNG | CL 29Z43 MQ | Does not turn on or st by lights up | Primary power supply zener diode dz 813 shorted. | Primary power supply zener diode dz 813 shorted | JR tec |
SAMSUNG | UN40F5500AG | Does not accept functions/commands only from the remote control, the TV keyboard works normally | When taking voltage measurements on the control board, the IR pin had a voltage oscillating from 1.4v to 1.8v. | Defect in ic1201, after taking all measurements of IR line components. The only thing left was the ic1201 as a defect, after changing the ic, the IR voltage stabilized at 3v3 and started accepting commands via the remote control again. | EC |
SAMSUNG | UN40F5500AG | Does not accept functions/commands only from the remote control, the TV keyboard works normally | When taking voltage measurements on the control board, the IR pin had a voltage oscillating from 1.4v to 1.8v. | EC | |
SAMSUNG | UN32J4000AG | Sem backlight, as normal | At first we thought it was a burnt out backlight, but in the end it was working 100%, the defect was caused by a smd 334 (330k) resistor that is positioned right next to the backlight power plug, it is between the cn1401 plug and the fet q1401. the resistor in question was damaged, just change it. | Check the resistor in question and replace it if its characteristics have replaced. | EC |
SAMSUNG | UN48H4203AG | Connect everything else without image | Defect was cd10 on the vcon changed it was just removed | <small>This email address is being protected from spambots. You need JavaScript enabled to view it.</small> | |
SAMSUNG | CL21A551ML | White image with retraction line and cushion effect | 200v track starting between d407 and j252 | MEO-ELETRÔNICO Cajupiranga (RN) | |
SAMSUNG | LT22A550 T22A550 | It works but the back light doesn't come on. replacement of the ICD801, DD850, QD850 on the power supply PCI. | Icd801-oz9998bng , dd850-sr210 , qd850 10l01 (mosfet). | It worked perfectly after replacing the components described. I used the 15l01 instead of the 10l01 and it worked very well. This TV monitor is using the bn44-00448b or bn98-03094b board. | Ferrarini |
SAMSUNG | LN32A450C1 | Loses image after a few seconds leaving only the sound | Lamps turn off after a while due to protection being armed | Put a 10k resistor from pin 15 to the ground of the oz9966sn on the inverter board! | Lucas |
SAMSUNG | PL51F4000 | Dead sign board | Diodo zener do +b 3,3v em curto | Replace zener d901 prox power supply connector | edmilsompimentel |
SAMSUNG | PL51F4000 | Sometimes it called, sometimes it took a long time to call | 3v3 that feeds the eprom with 4v5v, right, it would be 3.3v | Replace the regulator IC on the IC806 signal PCI. | edmilsompimentel |
SAMSUNG | 32D5500 | 12 volts pulsating | Fet qm855, put a 120k resistor from gate to ground | Rafael's tip | HP ELETRONICA |
SAMSUNG | 32D4000 | 12 volts pulsating | Cm855 fet, place a 120k resistor from gate to ground | HP ELETRONICA | |
SAMSUNG | UN50TU8000G | Turns on, lights up LED bus and turns off, no image, stays in this loop | I saw several videos trying to isolate the cause with the famous tape on the flat, that procedure of searching until you find a point that releases the display short and the TV releases the image. | I couldn't do it that way, because the short was in the first left flat, that is, looking at the TV lying on the counter with the screen down, the flat that was preventing the TV from working was the first one on the left side. on the left side vcon board tsound is the test point "vgh", the track of this vgh that goes to this flat was cut and the TV worked perfectly without any scratches on the image, to make the cut easier the cut was made close to the r44 on the left side vcon board, please note Tsound you have the vgh point test and the cut I made right after, that is, I will remove this vgh reference that goes to the first left flat... | MIGUELTV |
SAMSUNG | LS20CFSKFMZD | Turn off fabric | Place a 39k resistor from ground to pin 3 of the inverter ci | Velk JVM | |
SAMSUNG | UN32F5500 | Does not turn on or turn on standby | Identified the following burned components (fuse 5a, qm801cs - stf10nm60nd, icm801 - s3310) | I replaced the components above, instead of the (10nm60) I used a kp11n60, instead of the s3310, I used an s3330, taken from another scrap Samsung power supply, everything worked 100% - note; merits also for waterfall electronics | CDS_DIAS / LED TECH |
SAMSUNG | LN32D450G1G | LED flashes 3 times TV does not turn on | Q202 na pci principal | Replace the same | Williangb robista |
SAMSUNG | UN32EH4000AG | Duplicated and flickering image | Remove r25 and r37 | In my case, just removing the r25 and the r37 solved the problem. clean image. | bileu |
