Turns on but has no image. the black light turns on but tsound is no image.. | After checking the voltages on the main board I saw that tsound was a lack of power on the BGA chip. cause of the defect ci402 this ci that regulates the voltage of 2.5v.. it was giving 0.12v. | Replace the 2.5v voltage regulator IC402 on the main board | Diego de Lima Costa Nova Timboteua Pará |
