Doesn't start. nor the standby LED | Shorted smd ceramic capacitor. I replaced it with another one taken from another board and the TV turned on | Ewaldo Componel | |
| PANASONIC |
32FS600B
|
Burning leds | LED voltage is very high, around 71v. Tsound are 21 LEDs with a nominal voltage of 63v. | Reduce the LED voltage. remove r7820 and r7821 2r2. the voltage drops from 71 to 64v. | Katutto |

TV doesn't turn on only on ST BY. | Defective main board. | Shorted board swap, c382 and c383 10μF nano ceramic shorted, killing voltages on the board, located next to the ic206 8 pins. | RNSPTEC |
| SAMSUNG |
UN40J5200

TV turns on all voltages but no image | After several tests including on auto gen. The cause of the defect was in the ysus board transformer, which had one of the windings open. | When I removed it from the plate I noticed that it could be recovered. After recovery, the device started working normally again. | Valmir |
