Plug it into the socket and the LED comes on and goes off, it's very faint, when you put it in the socket the 130v is normal and drops, the 5v also drops to 3v and doesn't oscillate. | D432,d431,d840. | First d432 15v was replaced, then d431 9v1 and lastly d840 5v6 | Eronaldo(arteron) |

LC4245W
|
Enable Audio out output when using hdmi connection | 1) remove the smd resistors from positions r346 and r347. 2) replace the 33k smd resistors in positions r214 and r217 with 330k smd resistors 3) add jumpers from the positive terminal of capacitors c211 and c212 to the Audio out connector terminal, as detailed below. | technical bulletin | |

|
Low sound introduces noise in the audio | Isolate the PCI from the chassis, removing the SMD jumpers that connect the PCI ground to the chassis ground. in the position of the m806 screw, next to the tuner tsound is no jumper, so isolate the fixing screw with the chassis by placing a paper or plastic washer on the top and another on the bottom. | ||
