SAMSUNG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | UN32F4200 | Weak blinking backlight. LED voltage does not steady. LED bars ok | After analyzing the entire circuit, I realized that the 2 volt voltage at the gate of q9102c was pulsing | I replaced zd9104 zener 15 volts on the gate line of q9102c. resolved. | |
| SAMSUNG | T27A550 | It doesn't turn on and the standby LED doesn't turn on either. | Power supply board with all voltages and when disconnecting the cable that connects the power supply board to the main one, the display LEDs light up. | The defect is in the power supply. (cm807) replace the same 47x50 volts. | eletronica cachoeira |
| SAMSUNG | UN55F6800 | It doesn't turn on, the relay keeps hitting | Open ds806 diode | Ds806 replacement | Arnoltec |
| SAMSUNG | PL51F4500 | TV turns on normally, after warming up, the image appears. | Cp822 on the power supply board when it gets hot it shorts out, change it | Replace capacitor | CLAUDIO |
| SAMSUNG | LT 19B300 | TV works normally, turns off and shows blue, green and red colors with no image | The 202 ci e1 was replaced with no solution, returning the same defect, so I put a cooler on top of the processor and the result was nothing but the problem. | Defective pci card but it was mine and it was perfect until today, ok, sound's the solution for anyone who has one of these, ok, good luck and good service to everyone | eletronica publison natal rgn |
| SAMSUNG | UN40J5200 | Only the standby flashed, the LEDs did not activate after disconnecting the main power cable. | Faulty main transformer | Main transformer replacement | Arnoltec |
| SAMSUNG | PL43F4900AGXZD | Dull(weak) image with pigmentation | R4063, open smd resistor on the power supply board, x main circuit. | CARRIJO | |
| SAMSUNG | LN26A330 | White image | Power supply at vcom was low, 6v | As I didn't have the schematic for this board, I isolated the power supply paths from the flat that goes to the TCOM, soldered a wire to the VCOM fuse (screen board) and removed 12V directly from the power supply. it worked perfect. | TECNARDI |
| SAMSUNG 4K | UN49NU7100 | Image only in the middle of the screen. like a strip of light in the middle of the screen with a normal image and the sides, everything is dark! | Burned out led bars. | Replace the LED bars for identical ones. replace resistors r9201 and 9101 with this value (4r7 x 2w). Replace or sand the light diffuser acrylic as this TV model burns out the LED and also the acrylic. | EvandoViana |
| SAMSUNG | UN32EH4000G | Flickering image | Removing the resistor r47 0 from the display's v con board and placing a 1k resistor was perfect | badri eletronica | |
| SAMSUNG | PN51H4500AG | Istand bay blinks but doesn't turn on | 20 n polyester capacitor replace the same | Capacitor replaced | ELETRONICA SALES.NATAL RN |
| SAMSUNG | PL42C450B1 42UN | No audio | Short in capacitor c1371 | Removing the shorted capacitor | SMART TECH |
| SAMSUNG | UN40F5500AG | Stdby led flashes 2x and nothing turned on apparently shorted power supply board | Backlite did not light up and did not send a PCI signal. | Plate oxidized in short, I cleaned it and it came back to life. | RODRIGO GUIMARÃES |
| SAMSUNG | PL43E400 | Doesn't turn on, just blinks on standby | Main board, just change it and run for the hug | Voltages go and vs normal. | Cabeça |
| SAMSUNG | HG40NC450HG VERSÃO US01 | TV works, but with dark image and backlight off. | Ovp voltage of the IC9101 with almost 4V, causing the backlight to trip. | Glue of resistors r9103 r9104 and r9105 showing leakage. After cleaning, it started working normally again, with the correct voltage of 2.6v on pin 16 of the ic9101. | electronicssupplyparts - Gramado/RS |
| SAMSUNG | CL21Z40MQ | It turns on with a black screen with no image, as if the defect was abl, if you enlarge the screen, the white screen appears with lines of retraces. w | Change to memory. | DJ PITUKA | |
| SAMSUNG | LN32C530F1M LN37C530F1M | Stand by led on, TV doesn't turn on, doesn't accept commands, 13v missing. | Defective primary icm801. | electronicssupplyparts - Gramado/RS | |
| SAMSUNG | LN46D550K7GXZD | With sound, backlight does not come on | Cp 820 with small leak, almost imperceptible | Capacitor replaced | Telesom MS |
| SAMSUNG | UN55F6400 | The relay keeps hitting | R802 smd (next to ci ics801 on the power supply board) of 10 r is changed | Replace r802 | Eletronicaaeb |
| SAMSUNG | UN40B6000 | Turns on and off immediately or keeps trying to start giving the impression of corrupted memory | Defective t-com | C.i regulator ic107 faulty, with voltage below 1.5v | Stiltec |
