| SAMSUNG | TODAS | Turns on, the LED bars light up, but the screen does not show a gray screen image | Capacitor in the vcon short, just change it | Fernando | |
| SAMSUNG | PL-42S5S(L) | It doesn't turn on, it just turns on standby | Power supply board - 2 blown capacitors cm815 and cm816 | After replacement, it worked normally. | CELSOKAYRAN |
| SAMSUNG | UN40H5103 | League; but the screen keeps changing the colors of the plot; red, green blue and white, then repeat everything. | Flat cable that connects the main board to the screen, clean both sides and replace. | py1acb | |
| SAMSUNG | PL43E490 | TV turns on with no image, normal sound, VS and VA voltages appear and fall slowly, LED on the logic board lights up for 5 seconds and goes out for 2 seconds | Blue ceramic capacitor c5074 331 1kv on y/x sus board with leakage | shermanflima | |
| SAMSUNG | UN24K4000 | Backlight does not come on, no image | Power supply transistor fet dc-dc converter ap 9997gh shorted | Replace do transistor fet smd ap 9997gh | |
| SAMSUNG | CL-21Z58MQ | Blinking LED does not turn on | Micro inductor l808 which is in series with the +b line of the flayback was open!! | Replace l808 | Lucas |
| SAMSUNG | S19A300B | Doesn't start | Ci 402 faulty memory | Ci 402 s24cs0 | GUINGA sdia - goias |
| SAMSUNG | UN32H5550 | Power supply does not turn on | Switching ci, and have burnt out, | Replaced the IC with one from the known market s3330 and a fer 11n60. | Estevão |
| SAMSUNG | PS-42C91H BN44-00194H | Works less than 1 minute and turns off | Power supply with problems with capacitors c805 and c806 220µf/450v | Replace defective capacitors | Jocix |
