| AOC | L19W931 | Lamps don't light | Even after changing c930 lamps do not light up, add another 1000 x 24v capacitor | Put capacitors in parallel...adding 2000 micro farads | Maurilio |
| PHILCO | TP20V56 | It doesn't turn on, it just stays on, the LED is on | When you press the switch, the LED flashes, the voltage does not arm and drops, the vertical stv9302a is defective, I replaced it and the electrolytic capacitor with its capacity depleted c918 and c914 - 1000ud 16v | Defect resolved | Andre |
| LG | 60PB6500 | Turns on and then turns off | Power supply vs high 240v | Open coupler photo. ic503 | Eletro Center |
