Turns on, the LEDs that illuminate the panel light up but the display does not light up and no function works, because tsound is a lack of 12v that goes to the front panel | Diode d7, smd diode (in the body of the diode is s8) on the amplifier board, circuit that makes 12v that goes to the front panel | Replacing the s7 diode with a normal her105 diode. | MIGUELTV |

Vertical only opened from the middle down | After breaking the head, I changed capacitors, tested with another deflector, I re-recorded the eeprom, looked at resistors and diodes, but when I moved the board, the vertical one opened, I saw with a magnifying glass it had a small crack and even testing continuity with r3465 and c2463, it was good, so I made one wired jamp the tv was cool | Make a jamp with wire from c2463 to r3465 this model usually gives problems with trails | Bardock Eletronica |

Turns it on at DC ON and works normally, when you turn the key to AC ON, the green and red LED flashes but it doesn't charge, it doesn't work USB memory SD | I found some components in the primary power supply - ec1-100uf 450v making a liquid under the capacitor, I replaced it with the new c3-22uf 50v exhausted, r13-10r open smd u1-pc817 with leak, and in the secondary I found c8-1000uf 25v exhausted, c9 - 2200uf 25v exhausted, but c15 and c25 - 1000uf 16v exhausted zd3-c5v1 with leakage replace without measuring r27 and r16 - 22k smd all with weak resistance replace | Defect resolved amplifier box everything was ok | Andrei |
