The LED turns on, but it blinks after pressing the button. | Capacitors c17f and c21f (1000uf 25v), c23f and c48f (470ufx16v) and the two under the heatsink c20f and c18f (680ufx16v) all swollen, except the c48f which was measuring 187uf. | I also recommend tinning the terminals of this board that fit into the lamp connectors. tsound were two that were charred. | Flavio |

When turned on, it comes with audio, but with a high-pitched horn sound. | The cause of the defect is the clock oscillation x600 crystal. located next to two capacitors on the left facing away from the device. | Replace of the same. With the device turned on, place your finger on the indicated crystal and it will make a different noise. | JC Eletrônica Cícero |

Turn on normal image after about 3 minutes, turn off the LEDs | I tried all the good bars, I tested returns ok, I removed the transistor q3 and nothing, I noticed a difference in temperature between the two ci u1 and u201 on the inverter board, I solved it by putting a heat sink and it didn't turn off anymore note: you can change the ci | Eletrônica alternativa (TEC Mijail) | |
