Power supply: does not activate the high power supply (without 12v) | Ci driver u501 inoperative. reason: zener diode zd503 (5v6) killing the fadback voltage of the IC (pin 2 of the IC) obs voltage in very fast peaks, it is not possible to visualize it with a multimeter, only with an oscilloscope. | Replace of zd503 (5v6) is connected to pin 2 of ic u501 (ncp1207a) | Gênios Eletronica SJ SC |

Only lights up the LEDs without an image (only lights up LEDs) | Dirt in the fittings but it is very light, you have to clean it to see if it resolves it. | Cleaning the screen flat cable and cleaning the flat fitting on the board and screen side (clean with paper and cotton swab, then clean finally with contact cleaner) | Márcio Pereira |

In protection | C811, c812 r821. the 15v kia7815 regulator gets very hot....but apparently this is normal. it feeds all cards to output drivers with. 15vIf you leave the module outside the heatsink in the test, the module goes into protection as this regulator heats up and the power supply protects due to a lack of 15v voltage. Do not connect the module without the card board with the transistors...as they may short out | Replace days roasted components | Mitzko eletrônica |

Doesn't start. | Short circuit in the secondary 12v line of the power supply. smd capacitor positions c997 and c1000 short, and ci position u809 defective, inputs 5v and 12v but does not come out at the terminals (5 and 6 outputs 5v) and (7 and 8 outputs 12v) | Changing the capacitors, use two 10x16v or one 22x16v, and changing the ci me4953 | rafaelmoraes99 |

Lights up the light, doesn't show the logo and goes out, with the LED flashing 5 times. | I found that the voltage above the avdd point did not remain, sometimes tsound is a short in one of the 4 filter capacitors on that line, in my case it was the ci itself, the icd1, bm81204, I put the sm4154 in its place and it went boom. | Davi.sls | |
