Does not turn on LED. and when it turns on, it only turns on via the control and with the vertical closed at the bottom. | The reason why it only turns on via the control is the keys on the keyboard. and the cause hanging with closed vertical is the eepromm memory. note; also change the 100/35 volt c302 which was exhausted. | Replace the keyboard keys and the c302 with 100/35 vertical turns. | <small> |

Turns on the panel LEDs, but with no function and the display is off and tsound is no audio | Shorted smd diode d3 is next to coil l5 of diode d7 and resistor r18 | At first I was suspicious of the microprocessor but it wasn't checking the power supply PCI and it was normal, then I went to the mother PCI checking the components I found this diode short I saw that it wasn't a zener but a rectification diode, I looked for its diagram on the internet and it didn't work. I found it, I decided to put a common diode in its place (in4007) the device even turned on and worked, but after a short time in operation its panel started to weaken, I noticed that the diode I had placed was overheating, I turned it off immediately, I stopped To think about it, I decided to put another diode in its place, but with a high switching speed, like the ones used in TVs that come out of the flyback and feed the vertical output, for example, I put one of those from a TV and the device was zero, it worked normally, I left it for a long time under test (note the diode that I removed from the chassis of a scrap TV, its code is tvr10g) | rubertan |

Only tuning the vertical channels, and auxiliary socket not turning off when the device is turned off | Open smd transistor q101(1b) this code is on top of the transistor | Replace it with another one with the code (1bw) that I found in a scrap Philips TV, the device was zero | rubertan |

No audio | Carbonized resistor r131(33r), electrolytic capacitor c221(220/16v) shorted | At first I replaced the resistor which was cabled but as the capacitor was shorted the resistor began to char, I checked the circuit and saw that the resistor was on the power supply line of the audio ci u200 (la1140) and following the line I found this Shorted capacitor measuring 0Ω on the multimeter, I replaced the capacitor and the resistor the device was zero | rubertan |
