Tv lg 32ln540b shows the logo and then restarts.
The first thing is to check the source, the electrolytic capacitors that may have suffered the discharge, especially one like 10 micros aa 5ov well at the moment I do not remember the exact value is what filters the source of the blakley diodes that so that describes the problem is 1st by the filter as well as a diode of a strip that is burned.
hello I already did it remained the same but the damage is in the short main card at the entrance of 3.5vdc and earth I'm still looking for.
hello the source is fine the stable voltages the damage is in the main card has a short at the output of 3.5vdc and earth I'm still looking for greetings.
There is a very efficient way to find short circuits in the main, you have to circulate current through the line that is short, the component that is bad will hurt and heat
Watch this video is an example, I use a power source with regulated current
in the video they use a laser sensor, if you can't use the fingers, hehehe

Hi I can not do what you say because the TV does not respond to any command with the keys and control less. Greetings.
It is not with the remote control that the television has, it is a special one that sells the LG and works when the TV is turned off if it does not succeed, it will have to try another main
