SAMSUNG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | QN50Q60TAG | Tsound is no image, the backlight turns on. | Defect in v-com | Break the vhg trail near r44 (on the v-com board). | Baguatech |
| SAMSUNG | UE55H6200AWXXC | Power supply bn44-00711a.stdby power supply on this power supply is 8v on stdby and 13v on pwr-on. it had 4v | The icm801 pwm does not provide impulse from pin 11 to the qm802cs gate | Replace the icm801 (fa6ao1) and the cm813 and cm816 capacitors (2x 22μF - 50v) | Electrohd |
| SAMSUNG | PL60F5000 | Blurred image | Two 120Ω resistors each open are in position r5084 and r5097 | In this case they must be in parallel because measuring on the 60Ω board it is right at the tip of the ysus board | Claudio de Oliveira |
| SAMSUNG | UN50TU8000 | Turns on without image and turns off | A bad screen loosens the flex cable that comes out of the main board. If it sticks, it's a screen defect. You can try putting some tape on the brown cable, but it's not always 100x100. | Cabeça | |
| SAMSUNG | T24C310LB | Doesn't start | Ic1601 (tps54328 or tps54327) makes the 5v supply and ic201 (1g1n or 1g1d 3v3 regulator), this tv uses an external 14v power supply if you put it higher it burns | Julian C Braga | |
| SAMSUNG | CL21A551MLMXDD | The sound cutting | Replace resistior 4k7 r914 | Joel Isidoro da Silva Reis | |
| SAMSUNG | UN40F6400 | Standby LED flashing, TV does not start. no image, backlight does not light up. | The problem appears to be the main board, if you disconnect the TCON TV it will work normally again. | Tcon replace | TREK |
| SAMSUNG | LN46C530F1M | It didn't turn on, it stayed on stand by | Ci of the aoz1031 main board, just change it and it will work again, to see if it is the main board, disconnect the cable that goes from it to the power supply board, if the screen turns on it is a sign that the power supply board is good. | Alice eccel | |
| SAMSUNG | UN40EH5300 | Burning leds | Voltage of the LEDs with 210.5v | Replace the leds and replace the value of r9113 to 1.2r (voltage drops to 184.5v ÷ 60 leds = 3.075v for each led) | Evando Viana |
| SAMSUNG | UN40EH5300 | It turns on immediately and restarts (in a loop) sometimes it works normally. | Short on the 1.5v line (1.5v voltage only with 0.98v...) causing the shorted dft smd capacitor c1170. | Replace the c1170 for another identical one. good luck... | Evando Viana |
| SAMSUNG | 47LA6200 | Image with stripes, tcom makes a snoring sound. | Tcon voltage with 11v, change q2407 in the main, feeds 12v to tcon. | joaomvjr | |
| SAMSUNG | LN26R71BAX | No image (blue), white image, locked image, sometimes connected with green stripes. | When you flick the TV the image comes back, one of the flats, on mine on the right. cold solder on the acf, on the side that presses on the v-com | Tsound are 2 screws that hold the v-com in the housing, if you loosen it, that solves it, in my case I still prefer to solder with tin only on the side written 0821-a (on the flex) the 14 pins | lucian oliveira 61991271532 DIGITAL TECH |
| SAMSUNG | TA550 TA27A550 | Turns on, the LEDs do not light up, maintaining a very dim image that is noticeable only by lighting the screen with a flashlight | Suppressor capacitor pcx2-337 (470nk275v, pikor, blue, only on the power supply board) | Capacitor replaced | Marcelo Simões |
| SAMSUNG | PL43F4900 | Negative image, all pigmented and reddish | Change video card | Cabeça | |
| SAMSUNG | CL-29K40MQ | Do not turn on, LED off power supply goes into protection, high power supply 160v. | An oxidized jamp, that feeds the memory, p-281 | Matheus | |
| SAMSUNG | LN26D450G1G | The screen flashes and sometimes restarts | Lack of pfc actuation (400v), caused by the ps-on command being low | The defect is in the q202 transistor, npn transistor, just replace it with another one and go for a hug! | Lucas |
| SAMSUNG | LN26D450G1G | The screen flashes and sometimes restarts | Lack of pfc actuation (400v), caused by the ps-on command being low | The defect is in the q202 transistor, npn transistor, just replace it with another one and go for a hug! | Lucas |
| SAMSUNG | PL43F4000 | Image progressively grainy in some parts | A sus repair kit was replaced and the q 5000 rjp63k2 was fake | Replacing the q5000 transistor with an original one, be careful guys, tsound are a lot of these fake ones out tsound | PAULO PINHO |
| SAMSUNG | UN50TU8000G | One more case: turning off and on, loop | In the small flat (with to with) left side (wsound the flat cable from the main board comes in) from left to right (as it is written) isolated 3 tracks only, TV working normally | Claudio Jorge Eckert Junior | |
| SAMSUNG | UN49J5200 | LEDs burn out frequently. | When changing the LED bars, which are made of aluminum, completely isolate them from the TV housing. | The solution is to isolate the aluminum LED bars from the TV chassis | Antônio |
