TV turns on normally with sound without image, you can see the LEDs on the screen lit up | Shorted smd capacitor on the display board (screen) - it kills the voltage coming out of the t-con approx 16v generated in the coil circuit | I just removed it and the screen showed the image normally. | |

It doesn't turn on, it just flashes on standby. | Power supply does not arm, standby voltage ok, secondary with oscillating voltages. This power supply has protection, when an LED has a problem or the bars are disconnected it does not activate. I spent some time analyzing it, thinking it was something in the power supply, but it was a problem with the LED bars. | Disassemble the panel and solder the LED bar connectors (in the middle). This type of bar gives poor contact and opens the series of LEDs. | GABSENS |

Turns on but does not reproduce image in both digital and analogue, does not identify the vga cable | I found information on the websites that it was about recording the eprom 401 (25x40) and that was really it | As I didn't have a 25x40 eprom I used a 25q64 used on a Philips TV and recorded the file and it worked.....ok...be careful that tsound is the right file for the display, I bought the file on the free market at same file as my display, as reports say that if you record with the wrong file the equipment crashes.... | MIGUELTV |

It doesn't turn on, the relay keeps hitting or sometimes it doesn't even hit the relay | Qb852 on the power supply board | It didn't arm the 12v, it had the normal 5v and on pin 18 a voltage of 3v3 ~ 0v was oscillating (when connected to the main PCI). transistor qb852 (replaced), which is on the power on/off line, close to the pc802s photocoupler. | EC |
