They could be lamps or candles.

Thanks Denis, you know of some simple method to try them. I live in Venezuela and everything is incomparable. Even an electrolytic capacitor are super expensive.

Today I connected the TV to the power, and I could see that the screen turned on well for a few seconds, and turned off again (it was protected). I haven't played the TV since yesterday. For the illumination of the screen I discard the CCFL lamps.

I already managed to turn on the TV, but if it has eprom memory failure, the volume to the maximum, lets press a key and locks. It does not work even with the remote control. Remove the control panel, check each of the buttons, and they are fine, check the associated resistors and they are fine, solve each button.

Hi friend, good morning. I have the same TV with the same or similar fault. I turn it on for a second how to try to give an image and the screen collapses. It does not give sound, because of the screws it is seen that the LED strips are giving brightness.

Reflow the main processor at 325 degrees and 4 air, for one minute, apply flux.

good night my friend, I have a 32lg30r TV that shows symbols, numbers and letters fail. There are moments that hang or turn off. I saw a tutorial apparently it is memory, someone knows how to replace it or reprogram it or a Garcia solution

The final problem was detected, because when you turn on the TV, the keyboard after a few seconds is locked, and you cannot use the remote control. The fault is the eeprom 24lc64 memory, it was tested with 24lc02, 24lc08 and 24lc16 memories, and the TV turns on starts with the auto-installation menu, the options can be selected, but when you start looking for the channels the screen goes black. The problem I am in Venezuela and I don't get that new eeprom.
