SOURCE: My 42" LG LCD turns itself off
There is probably a firmware update on the LG website that should take care of this.Go to the downloads area and enter the model number for available updates.

it sounds like a loose connection with your signal but if the connection is tight i have seen loose connectors on the small signal board itself which may be resolveable by resoldering connector on signal board which would be far less expensive than replacing signal board itself

It could be the mainboard or the powerboard.
You need to check those boards in order to figure it out wich one need to be replaced

If it is hot were you live , That model of t.v doesn't like heat, anything about 35 degrees celsius could cause a problem with the card components.

Since the sound remains, the power suply board is probably OK. There is a circuit called the "inverter" circuit that powers the backlight of the panel that could be defective. It is possible for the panel to be defective, but that is not common. If you can update this with the model number, I will locate the inverter board part number and cost. That is the most common failure part. Also, if this set is still under warranty (less than a year old), request warranty repair.
